ARTICLES
A clean tray containing
- A bottle with disinfectant solution (dettol 1: 40/savlon 1:20)
- A bottle with water
- Thermometer (rectal thermometer in case of rectal method)
- A small bowl with cotton swabs
- Paper bag/kidney tray
- Pens
- Flow sheet/graphic chart/paper
- Lubricant (in case of rectal/method)If using more than one thermometer, use 3 bottles (2 with antiseptic solution and one with water).
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1 | Ascertain method of taking temperature and explain procedure to the patient and instruct him how to co-operate. | |
a. In case of oral method, ensure that patient had not taken any hot or cold food and fluids orally or smoked in 15–30 minutes prior to procedure. | Causes alteration in temperature reading. | |
b. For rectal method, provide privacy and position the patient in a Sim's position. In young children position laterally with knees flexed or prone across lap. | Position ensures easy access to insert thermometer. | |
c. For axillary method, expose axilla and pat dry with a towel. Avoid vigorous rubbing. | Friction produced by rubbing can cause increase in temperature. | |
2 | Wash hands | |
3 | Prepare equipment | |
a. If glass thermometer is in disinfectant solution, transfer it to container with plain water using dominant hand. | Ensures complete removal of disinfectant and reduces irritation to tissues. Using dominant hand reduces chances of accidental breakage. | |
b. Wipe thermometer dry, using a clean cotton swab using rotatory motion from bulb to stem. | Wiping from an area of least contamination to an area of greatest contamination prevents spread of organisms. | |
c. Shake down the mercury (if needed) by holding thermometer between thumb and forefinger at the tip of stem. Shake till mercury is below 35 degree centigrade (95 degree Fahrenheit). | Reduces chances of error in reading temperature. | |
4 | Take temperature | |
a. For oral method | ||
| Blood supply is more in this area and hence reflects the temperature of blood in the larger blood vessels. | |
| Clenching teeth can cause the thermometer to break and cause injury. | |
| Ensures accurate recording | |
b. For rectal method | ||
| ||
| Lubricant facilitates easy insertion without irritating mucous membrane. | |
| Taking deep breathe relaxes external sphincter thereby facilitating easy insertion. | |
| Ensures accurate recording | |
| Prevents thermometer from falling down. Ensures accurate recording | |
c. For axillary method
| ||
5 | Remove thermometer | |
Wipe using a cotton ball from stem to bulb in a rotatory manner. | Wiping from an area of least contamination to an area of greatest contamination will help in preventing spread of microorganisms. | |
6 | Read the temperature, holding thermometer at eye level and rotate it till reading is visible and read it accurately. | Holding at eye level prevents error in reading. |
7 | Shake down the mercury level | |
8 | Clean thermometer using soap and water. | Removes organic material. |
9 | Dry it and store it in disinfectant solution. | |
10 | Document temperature | |
11 | Wash hands | Reduces risk of transmission of microorganisms. |
12 | Replace articles. |
SPECIAL POINTS
- It is always best to use individual thermometer for each patient.
- When individual thermometer is not used in patient care-units (wards), axillary method is recommended.
- For converting temperature from centigrade to Fahrenheit following conversion formula can be used.C = 5/9 × F-32[C = degree centigrade][F = degree Fahreheit]
1.2: ASSESSMENT OF PULSE
DEFINITION
Checking pulse rate, rhythm, volume, etc. for assessing circulatory status.
PURPOSES
- To establish baseline data
- To check abnormalities in rate, rhythm and volume
- To monitor any change in health status of the patient.
- To check the peripheral circulation.
|
ARTICLES
- Wrist watch with second hand
- Pen (color as per agency policy)
- Vital signs chart and flowsheets
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1 | Explain procedure to patient and check if the patient had been involved in any activity. If so allow the patient to rest for 10 minutes before taking pulse. | Activity can increase the pulse rate. |
2 | a. Select the pulse site | Usually radial pulse is selected. If any particular extremity is to be assessed then another pulse site is to be selected. |
b. Assist the patient to a comfortable position. For radial pulse, keep the arm, resting over chest or on the side with palm facing downward. In sitting position, keep the arm resting over thigh with palm facing downward. | ||
3 | Palpate and check pulse | |
a. Place tips of 3 fingers other than thumb lightly over pulse site. | Thumb is not used for assessing pulse as it has its own pulse which can be mistaken for patient's pulse. | |
b. After getting the pulse regularly, count the pulse for one whole minute looking at the second hand on the wrist watch. | Irregularities can be noticed only if pulse is counted for one whole minute. | |
c. Assess for rate, rhythm and volume of pulse and condition of blood vessel. | ||
4 | Document and report pertinent data in the appropriate record. | |
5 | Wash hands. |
SPECIAL POINTS
- Never press both carotids at the same time, as this can cause reflex drop in blood pressure/pulse rate.
- Carotid pulse is used for victims of shock and cardiac arrest when pulse is not palpable at other sites.
- Brachial and femoral sites are used with cardiac arrest in infants.
1.3: ASSESSING RESPIRATION
DEFINITION
Monitoring inspiration and expiration in a patient.
PURPOSES
- To assess rate, rhythm and volume of respiration.
- To assess for any change in condition and health status.
- To monitor the effectiveness of therapy related to respiratory system.
ARTICLES
Wrist watch with second hand, graphic record, pen (color according to agency policy).
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1 | Ensure that patient is relaxed Assess other vital signs such as pulse or temperature prior to counting respirations. | Awareness of the procedure may alter the rate of respiration. Conscious patients when relaxed and unaware of procedure tend to have accurate respiratory rate. |
2 | Assess for factors that may alter respiration. | Allows nurse to accurately assess for presence and significance of respiratory alteration. |
3 | Wait for 5 –10 minutes before assessing respiration if patient had been active. | Activity may increase rate and depth of respiration. |
4 | Position patient in sitting or supine position with head elevated at 45–60 degree. | Ensures proper assessment. |
5 | Keep your fingers over the wrist as if checking pulse, and position patient's hand over his lower chest or abdomen. | Makes the patient less aware of his respiration. Keeping hand over chest or abdomen makes the movement of chest more visible. |
6 | Observe one complete respiratory cycle-inspiration and expiration. | |
7 | Assess rate, depth, rhythm and character of respiration. | Depth of respiration reveals volume of air moving in and out of lungs. Abnormalities of rhythm and character reveals specific disease condition. |
8 | Count respiration for one whole minute. | |
9 | Wash hands | |
10 | Record the findings and report any abnormal findings. |
1.4: MONITORING BLOOD PRESSURE
DEFINITION
Measuring blood pressure using a sphygmomanometer.
PURPOSES
- To determine patient's blood pressure as a baseline for comparing future measurements.
- To aid in diagnosis.
- To aid in the assessment of cardiovascular system preoperatively and postoperatively, during and after invasive procedures.
- To monitor change in condition of the patient.
- To assess response to medical therapy.
- To determine patient's hemodynamic status.
ARTICLES
- A sphygmomanometer comprising of:
- Compression bag/inflatable rubber bladder enclosed in a cloth cuff (appropriate size)
- An inflating bulb (by which pressure is raised)
- A manometer (mercury) from which pressure is read.
- A screw type release valve for inflation and deflation (pressure control.)
- Stethoscope.
- Patient chart for recording.
- Black/blue pen for charting.
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1 | Check physician's order, nursing care plan and progress notes | Obtains any specific instruction/information. |
2 | Explain the procedure and reassure the patient. Ensure that patient has not smoked, ingested caffeine or involved in strenuous physical activity within 30 minutes prior to procedure. | Obtains patient consent and co-operation and also relieves anxiety. Smoking, caffeine can increase blood pressure. |
3 | Wash and dry hands | Prevents cross-infection |
4 | Assist the patient to either sitting or lying down position | Obtains an accurate reading |
5 | Collect and check equipment | Ascertains evidence of malfunction |
6 | Position the sphygmomanometer at approximately heart level of the patient ensuring that mercury level is at zero. (Figure 1.4(a)) | Helps in obtaining accurate reading. |
7 | Select a cuff of appropriate size (Figure 1.4(b)) | Ensures that compression bladder width is at least 20% wider than the diameter of the mid-point of the exterimity used. If the bladder is too wide the reading may be erroneously low. If it is too small, the reading may be erroneously high. |
8 | Expose the arm to make sure that there is no constrictive clothing above the placement of cuff. | Ensures accurate reading. |
9 | Apply the cuff approximately 2.5 cm above the point where brachial artery can be palpated. The cuff should be applied smoothly and firmly with the middle of the rubber bladder directly over the artery (Figure 1.4(c)). | Ensures accurate reading Wrapping the cuff too tightly will impede circulation. Wrapping the cuff very loosely will lead to false elevation of pressure. |
10 | Secure the cuff by tucking the end under or by fixing the velcro fastener. | Prevents unwrapping of the cuff. |
11 | Place the entire arm at the patient's heart level. | Obtains accurate reading. For every cm that the cuff is above/below heart level. Blood pressure varies by 0.8 mm of mercury. |
12 | Keep the arm well rested and supported | Ensures comfort of the patient thereby enabling an accurate reading. Movement of arm can cause noise when auscultating. |
13 | Place yourself in a comfortable position. | |
14 | Connect the cuff tubing to the manometer tubing and close the valve of the inflation bulb. | |
15 | Palpate the radial pulse and inflate the cuff until pulse is obliterated | Estimates systolic pressure in order to determine how high to pump the mercury in order to avoid error related to auscultatory gap. |
16 | Inflate the compression bag a further 20–30 mm of mercury and then deflate cuff slowly. Note the point at which pulse reappears. Release the valve. | Ensures that mercury column is high enough to minimize error related to auscultatory gap. The point at which pulse reappears is the systolic pressure. |
17 | Palpate brachial artery and place diaphragm of the stethoscope lightly over the brachial artery. Ensure that ear pieces of the stethoscope are placed correctly (slightly tilted forward and ensure that tubing hangs freely) Raise mercury level 20–30 mm of mercury above the point of systolic pressure obtained by means of palpatory method (Figure 1.4(d)). | Ensures accurate reading. If diaphragm is placed too firmly the artery gets compressed. Sounds are heard better with correct placement of stethoscope. Rubbing of stethoscope against an object can obiliterate Korot-Kov's sounds. |
18 | Release the valve of the inflation bulb, so that mercury column falls at the rate of 2–3 mm of mercury/sec. | Prevents venous congestion and falsely elevated pressure reading due to slower rate of deflation and prevents erroneous reading due to faster rate of deflation. |
19 | When first sound is heard, the mercury level is noted, this denotes systolic pressure. | First sound is heard when the blood begins to flow through brachial artery. |
20 | Continue to deflate the cuff. When the sound disappears note the mercury level. This is diastolic pressure. | |
21 | Deflate cuff completely. Disconnect the tubing and remove the cuff from the patient's arm. | Occlusion of artery during the pressure reading causes venous congestion in the forearm. |
22 | Repeat the procedure after one minute if there is any doubt about the reading. | Waiting time of one minute allows venous blood to drain completely. |
23 | Ensure that patient is comfortable. | |
24 | Remove equipment and clean ear piece with a spirit swab. | |
25 | Wash and dry hands | Prevents chances of cross-infection. |
26 | Document the reading in appropriate observation chart or flow chart. | |
27 | Report any abnormal findings. |
SPECIAL PRECAUTIONS
- Do not take blood pressure on a patient's arm if
- The arm has an intravenous infusion on it
- The arm is injured/diseased.
- The arm has a shunt/fistula for renal dialysis.
- On the same side if the patient had a radical mastectomy
- If the arm is paralysed.
- Always check supine measurement before checking upright measurement.
- If blood pressure has to be taken at the same time in two or more positions— Lying, sitting or standing at the same time for comparison, wait for a minimum of 3 minutes after assuming that position before taking the reading.
- If comparison is needed for blood pressure in lying/standing position, the patient must be in lying/standing position for a minimum of 3 minutes.
- Appropriate sized cuff should be used.

3. | Reassure the patient and explain that relatively little blood will be taken | Obtains patient's co-operation and confidence. |
4. | Wash hands and put on gloves | Protects health care worker from possible exposure to blood. |
5. | Select and examine the vein, visualize the vein, including the antecubital area, wrist, dorsum (back) of the hand and top of foot (if necessary). Palpate the vein | Select a vein that is visible, palpable and fixed to the surrounding tissues so that it does not roll away |
6. | Instruct the patient to extend his arm. Hold the arm straight at the elbow with fist clenched | Proper positioning reduces risk of injury |
7. | Apply the tourniquet 5 to 15 cm above the selected site with just sufficient pressure to obstruct venous flow | A tourniquet when applied increases venous pressure and makes the vein more prominent and easier to enter. |
9. | Cleanse the skin with alcohol swab in a circular motion - center to periphery. Allow to dry | Cleansing the skin reduces the number of microorganisms |
10. | Fix chosen vein with thumb and draw the skin taut immediately below the site before inserting needle to stabilize the vein. | The vein may roll beneath the skin when the needle approaches its outer surface, especially in elderly and extremely thin patients. |
11. | Hold the syringe between the thumb and last three fingers with the bevel up and directly in line with the course of the vein. Insert the needle quickly and smoothly under the skin and into the vein (Figure 1.18(a)) | |
12. | Obtain blood sample by gently pulling back on the plunger (Figure 1.18(b)) | Use minimal suction to prevent hemolysis of blood and collapse of vein. |
13. | Release the tourniquet as soon as the specimen is obtained and ask the patient to open the fist. | |
14. | Apply sterile 2’ × 2’ gauze piece to puncture site without applying pressure and withdraw needle slowly along the line of vein | Slow withdrawl of the needle is less painful and reduces trauma |
15. | Request patient to apply gentle but firm pressure to site for 2 – 4 minutes | Firm pressure over puncture site prevents leakage of blood into surrounding tissues with subsequent hematoma development |
16. | Remove the needle from the syringe as soon as possible after withdrawing blood, gently eject the blood sample into the appropriate container without forming bubbles in the test tube or bottle (Some tests require container with anticoagulant) | Gentle ejection of blood prevents hemolysis |
17. | Invert the tube gently several times to mix blood with anticoagulant where applicable. For some tests blood is allowed to coagulate in the test tube | Gentle handling of specimen prevents risk of hemolysis. |
18. | Label specimen correctly and send to laboratory immediately with completed requisition forms. | Specimen should reach the laboratory with the minimum of delay for optimum reliability. |
19. | Dispose the needle and syringe in appropriate containers. | Avoids possible spread of blood-borne diseases. |
20. | Clean all spills with 10% bleach (sodium hypochlorite) solution. Remove gloves and wash hands. | Avoids possible spread of blood–borne diseases. |
21. | Record in the patient's chart the procedure and the tests for which the sample was sent to the laboratory. | |
22. | Replace the tray with the reusable articles in proper place |

3 | Gather articles at the bedside | Provides an organised approach during the procedure. |
4 | Explain the procedure to the patient. | Helps to gain patient's co-operation |
5 | Have the patient wash hands with soap and water. Use warm water if available. | Washing hands reduces transmission of microorganisms. |
6 | Position the patient comfortably in a semi-fowlers position or upright position | Increases blood flow to puncture site. |
7 | Wash hands. Don disposable gloves | Prevents spread of microorganisms. Gloves protects from exposure to blood and body fluids. |
8 | Remove test strip from the container and recap container immediately | Immediate recapping protects strips from exposure to light and discoloration. |
9 | Turn monitor on and check whether the code number on strip matches with the code number on the monitor screen. | Matching the code numbers on the strip and glucometer ensures that machine is calibrated correctly |
10 | Take the lancet without contaminating it. Select appropriate puncture site. | Aseptic technique maintains sterility. |
11 | Massage side of finger for adults (heel for children) toward puncture site and wipe with alcohol swab. | Massage increases blood flow to the area. |
12 | Hold lancet perpendicular to skin and prick site with lancet. (Figure 1.19(a)) | Holding lancet in proper position facilitates proper skin penetration. |
13 | Wipe away the 1st drop of blood from the site. | The first drop may impede accurate result because it may contain large amount of serous fluid. |
14 | Lightly squeeze or milk the puncture site until a hanging drop of blood has formed. | The blood droplet should be large enough to cover the test pad on the strip and it also facilitates accurate test results. |
15 | Gently touch the drop of blood to pad on the test strip without smearing it (Figure 1.19(b)). | Smearing of the blood will alter results. |
16 | Insert strip into glucometer according to directions for that specific device. Some devices require that the drop of blood is applied to a test strip that has already been inserted in the monitor. (Figure 1.19(c)) | Correctly inserted strip allows glucometer to read blood glucose level accurately. |
17 | Apply pressure to puncture site using a dry cotton ball. | This will stop bleeding at the site. |
18 | Read blood glucose results displayed on the monitor and inform the patient about results. (Figure 1.19(d)) | |
19 | Turn off the glucometer | |
20 | Dispose supplies appropriately and discard lancet in sharp's container. | Reduces contamination by blood. Sharps must always be handled properly to protect others from accidental injury. |
21 | Remove gloves and discard. Wash hands. | |
22 | Record blood glucose level in the chart | This facilitates documentation of procedure and provides for comprehensive care. |
SPECIAL CONSIDERATIONS
- In patients who require regular blood-glucose monitoring, shallow penetration should be encouraged to avoid tissue damage.
- Rotate or change sites to allow time for the penetrated site to heal.
- To reduce pain, choose side of fingertips or side of heel for children. where few nerve endings are present rather than central part of fingertips.
- Patients should compare their personal glucometer reading with the laboratory measured blood glucose level, every 6–12 months.

- Sign at bedside that patient is on intake and output measurement.
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1. | Identify the patient | |
2. | Explain the methods of maintaining. Intake and output. All fluids taken orally must be recorded on the patient's intake and output form (Input and output flow sheet) | Helps to obtain patient's co-operation and encourages patient's participation. |
3. | Wash hands every time prior to giving oral fluids | Reduces transmission of microorganisms |
4. | Measure all oral fluids in accordance with institutional policy Example: a. Water glassful = 200 ml b. Cupful = 120 ml Paper cup a. Large = 200 ml b. Small = 120 ml Soup bowl full = 180 ml Water pitcher full = 1000 ml Measure all fluids in the graduated cup/tumbler before giving to patient. | Provides for consistency of measurement |
5. | Record time and amount of fluid intake in the designated space on bedside chart. Include all semi solid and liquid food rich in fluids (oral, IV, tube feedings and IV fluids) | Documents the amount of fluids accurately |
6. | Transfer eight hours total fluid intake from bedside intake and output chart to 24 hour intake and output record in patient's chart. | Provides for data analysis of the patient's fluid status every 8 hour shift. |
7. | Record all fluid intake in the appropriate column of the 24-hour record | Documents intake by type and amount |
8. | Complete 24-hour intake record by adding all eight hour totals. | Provides consistent data for analysis of the patient's fluid status over a 24 hours. |
9. | For measuring output include urinary output and other drainage from patient. (Figure 1.24(a)). | Documents the amount of output accurately. |
10. | Urinary output • After each voiding measure the urine using a measuring container and record it with the time of voiding on the intake and output form (Figure 1.24(b)). | |
• For patients with retention catheter empty the drainage bag into a measuring container at the end of the shift or at prescribed times if output is measured more often. • For infants and incontinent patients the output may be measured by first weighing diapers or incontinent pads that are dry and then subtracting this weight from the weight of soiled items Note and record it. | ||
11. | The amount and type of fluid (urine, drainage from NG tube, drainage tube) are recorded in the intake and output form | Documents output. |
12. | Transfer 8 hour output total to 24 hours intake and output record on the patient's chart. | Provides for data analysis of the patient's fluid status. |
13. | Complete 24 hours output record by totaling all 8 hours total. | Provides consistent data for analysis of the patient's fluid status over a 24 hours period |
SPECIAL CONSIDERATIONS
- Proper aseptic technique should be taken while handling patient's body fluid output viz blood, urine etc.
- Remember that fluids taken to swallow pills must be recorded as intake
- Do not have visitors or family members empty bedpan, urinal or catheter bags.
1.25: TEACHING BREAST SELF-EXAMINATION (BSE)
DEFINITION
Breast self–examination is a technique which women use to assess their own breasts to detect breast carcinomas at the earliest.
ARTICLES
- Mirror
- Gloves
- Small pillow/rolled towel.
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1. | Identify the patient and review personal history and family health history. | Identifies risk factors and previous baseline data |
2. | Explain procedure to the patient. Ask her to disrobe to the waist and to put on a gown with the opening in the front | Provides easy access while maintaining maximum privacy |
3. | Wash hands. Don gloves if required by agency policy | Prevents transfer of microorganisms and possible contact with discharge when palpating nipples |
4. | Provide privacy and assist the patient to sitting position facing you and expose chest and breasts. | Allows comparison of breasts bilaterally |
5. | Explain and teach breast self–examination as you examine. For inspection, ask the patient to stand before the mirror and check both breasts for anything unusual with patients:
| • Flesh color, slight inequities in size and symmetry, rounded shape and smooth skin surface is normal. • Redness, blue hue, retraction, dimpling, enlarged pores, edema, lumps, lesions, rashes, ulcers and discharge are abnormal. • Supernumerary nipples along the milk line are a normal variant. |
6. | Explain and teach the palpation method. Teach the patient to use the right hand to palpate the left breast and vice versa. During the examination, place the patient's fingers under your fingers | Teaching during examination reinforces the need for and understanding of breast examinations, and enables the patient to identify normal breast tissue and abnormal tissue if present thus increasing confidence in performing BSE |
7. | Using the pads of the palmar surfaces of the fingertips, palpate the right breast by gently compressing the mammary tissues against the chest wall. Palpation may be performed from the periphery to the nipple, in either concentric circles, wedge sections or vertical strip (Figure 1.25(b)). | Warm temperature, elasticity, tenderness, pain, erythema, masses or nodules are abnormal. |
8. | Palpate areola and nipple using a similar circular technique as with breast. Pay special attention to subareolar part and gently press the nipple between the fingers | Inflammation, discharge, nodules fissuring and lesions are abnormal. |
9. | Palpate into axilla starting at anterior axillary line and continuing at an angle to the mid axillary line and up into the axilla (using same circular fingertip motion). Have patient place arm at side and palpate deep into the axilla. Identify posterior axillary, central axillary, anterior axillary and lateral axillary node locations. | Nodes should be less than 1 cm and non tender |
10. | Repeat steps 7–9 on the left breast, areola, nipple and axilla. Identify normal versus abnormal as with the right breast. Compare breasts bilaterally | |
11. | Assist the patient to supine position. Place arm on examination side under the head, and place a small pillow under the same side scapula | This position spreads breast tissue over the chest wall maximizing palpation accuracy |
12. | Assist the patient to palpate the breast, areola and nipple as in steps 7–9 with the other hand and vice versa | Re-evaluate examination findings in second position |
13. | Assist the patient to a sitting position. Review the steps and ask the patient to demonstrate breast self-examination | Provide more comfort for patient. Evaluate success of the teaching |
14. | Allow patient to dress | Provide for patient's comfort |
15. | Remove gloves and wash hands | Reduce transmission of micro-organisms |
16. | Give the patient written materials to reinforce teaching | Reinforce teaching. Provides a readily available form to patient for reference when at home |
17. | Record date, time, findings of abnormalities and absence of abnormalities, patient's response to findings and teachings |
SPECIAL CONSIDERATIONS
- Instruct patients not to use creams, lotions or powders and not to shave underarms 48 hours before the scheduled assessment, because these things could alter the breast skin or cause folliculitis and lymph node enlargement.
- Explain that BSE is best performed after menses (5th –7th day) for pre-menopausal women and first day of the month for postmenopausal women.
- Educate even men to perform a monthly BSE and obtain a clinical examination every 1 to 3 years because 1% of all breast cancer is found in men.
- Advise the patient to palpate her breasts during shower, as the fingers will glide easily over soapy skin, so that one can concentrate on feeling for changes in the breasts.
- During BSE pay special attention to upper outer quadrant area and the tail of Spence, where about 50% of breast cancers develop.
- Instruct patient that a baseline mammogram is to be obtained at 35 years and followed by annual mammogram after 40 years.
- Determine if patient is taking oral contraceptives, digitalis, diuretics, steroids or estrogen hormones. These medications may cause nipple discharge and hormones may cause fibrocystic changes in breast.
- Instruct mother to report if any lumps, tenderness or nipple discharge exists.
1.26: TEACHING TESTICULAR SELF–EXAMINATION (TSE)
DEFINITION
Testicular self-examination is a technique used to examine the testes by self for detecting abnormalities like testicular cancer.
PROCEDURE
Nursing action | Rationale | |
---|---|---|
1. | Identify the patient and review personal history, medication, and family health history | Identifies risk factors and previous baseline data |
2. | Explain the procedure to patient, provide privacy and ask the patient to disrobe completely and to put on a gown | Obtains patient's co-operation and provides easy access while maintaining maximum privacy |
3. | Wash hands, and apply clean gloves | Practices clean technique |
4. | Instruct the patient to stand and fold up his gown to expose the genitalia | Provides best exposure for examination |
5. | Advise the patient to use both hands to palpate the testes. The normal testicle is smooth and uniform in consistency. Note the size, lie, shape, consistency and tenderness The length of a normal testes should be greater than 4 cm and the volume greater than 20 ml | The left testicle normally sits slightly lower than right testicle. The testicles are rubbery and approximately equal in size Pressure on testes normally produces a deep visceral pain. Twisting or torsion of the testes causes venous obstruction, edema and eventually arterial obstruction. |
6. | Advise the patient to palpate each testis one at a time and feel for any evidence of a small, pea size lump or abnormality (Figure 1.26(a)) | |
7. | Teach the patient to locate and palpate the spermatic cord and vas deferens between the thumb and fingers (from epididymis to the inguinal ring) (Figure 1.26(b)) | Note any nodules or swelling |
8. | Explain that it is normal to find that one testis is larger than the other | |
9. | Assist the patient to a comfortable position. Review the steps and ask the patient to redemonstrate testicular self-examination | Provides more comfort for patient. Evaluate success of the teaching given. |
10. | Remove gloves and wash hands | Reduces risk of transmission of microorganism |
11. | Give the patient written materials if available. | Reinforces teaching. Provides a readily available form to patient for reference when at home |
12. | Record date, time, findings of palpation and patient's response to findings and teaching. |
SPECIAL CONSIDERATIONS
- Advise patient to perform testicular self–examination on one particular day of each month.
- It is advisable to perform testicular self–examination after a warm relaxing shower.
