Physical Assessment - 2026 Exam Techniques

1. A nurse is conducting a physical assessment of a newly admitted client. Which of the following observations made during the "General Survey" is classified as a behavior assessment rather than a physical appearance assessment? A. The client has symmetrical facial features and upright posture. B. The client's skin is warm and dry, with no visible lesions. C. The client maintains eye contact during the interview and responds in a cooperative tone. D. The client is wearing clean, season-appropriate clothing. Correct Answer: C. The client maintains eye contact during the interview and responds in a cooperative tone. Rationale: The general survey includes assessments of physical appearance, body structure, mobility, and behavior. Eye contact, cooperation, mood, facial expressions, and speech are behavioral assessments. Posture (A), skin condition (B), and clothing/hygiene (D) are physical appearance and body structure observations. 2. When performing a head-to-toe physical assessment on a client, which standard sequence of physical examination techniques should the nurse follow for most body systems? A. Palpation, Inspection, Auscultation, Percussion B. Inspection, Palpation, Percussion, Auscultation C. Auscultation, Inspection, Palpation, Percussion D. Inspection, Auscultation, Palpation, Percussion Correct Answer: B. Inspection, Palpation, Percussion, Auscultation Rationale: The standard sequence of assessment for the physical exam is Inspection first (always look before touching), followed by Palpation (feeling), Percussion (tapping), and finally Auscultation (listening). This logical progression allows the nurse to collect visual data first and then gather tactile, density, and sound data. The only exception to this sequence is the abdominal exam (I-A-P-P). 3. The nurse is preparing to assess a client's abdomen. In which order should the nurse perform the examination techniques, and what is the clinical rationale for this sequence? A. Inspection, Palpation, Percussion, Auscultation; to prevent bruising the liver. B. Inspection, Auscultation, Percussion, Palpation; because palpation and percussion can stimulate bowel motility and falsely alter bowel sounds. C. Auscultation, Inspection, Palpation, Percussion; to hear the bowel sounds at their loudest baseline. D. Palpation, Percussion, Auscultation, Inspection; to locate pain first. Correct Answer: B. Inspection, Auscultation, Percussion, Palpation; because palpation and percussion can stimulate bowel motility and falsely alter bowel sounds. Rationale: For the abdominal exam, the sequence is modified to Inspection, Auscultation, Percussion, and Palpation (IAPP). Pressing or tapping on the abdomen (palpation and percussion) stimulates peristalsis and bowel activity, which can falsely increase the frequency and character of bowel sounds heard during subsequent auscultation. By auscultating first (after visual inspection), the nurse captures the true, undisturbed state of the bowel sounds. 4. During a physical assessment, the nurse wants to evaluate the temperature of a client's skin. Which part of the hand should the nurse use to perform this palpation? A. The palmar surface of the fingers. B. The fingertips. C. The dorsal aspect (back) of the hand. D. The ulnar surface of the hand. Correct Answer: C. The dorsal aspect (back) of the hand. Rationale: The dorsal aspect (back) of the hand has the thinnest skin, which makes it highly sensitive to temperature differences. Fingertips (B) are best for fine tactile discrimination (pulsations, texture, skin turgor). Palmar surfaces (A) and ulnar surfaces (D) are best for detecting vibrations (tactile fremitus). 5. The nurse is assessing a client's thorax for tactile fremitus (vibrational tremors). Which part of the hand is most sensitive to vibrations and should be used during this palpation? A. The fingertips. B. The dorsal aspect of the hand. C. The palmar surface of the hand or the ulnar border. D. The thumb. Correct Answer: C. The palmar surface of the hand or the ulnar border. Rationale: The ulnar border (side) and the palmar surface (metacarpophalangeal joints) of the hand are the most sensitive areas for detecting vibrations. Fingertips (A) are used for fine touch. The dorsal surface (B) is used for temperature. Thumbs (D) are not used due to their own strong arterial pulsations. 6. The nurse is performing indirect percussion of the thorax. Which technique describes the correct application of this percussion method? A. Strike the client's chest wall directly with the palm of the hand. B. Place the stationary middle finger of the non-dominant hand firmly against the client's skin, and tap the distal joint of this finger using the middle finger of the dominant hand, flexing at the wrist. C. Press all fingers of the non-dominant hand on the chest and strike the forearm with the fist. D. Use a reflex hammer to tap the chest wall directly. Correct Answer: B. Place the stationary middle finger of the non-dominant hand firmly against the client's skin, and tap the distal joint of this finger using the middle finger of the dominant hand, flexing at the wrist. Rationale: Indirect (bimanual) percussion involves placing the pleximeter (stationary finger, usually the middle finger of the non-dominant hand) firmly against the client's skin, lifting all other fingers off the skin to avoid dampening the sound. The plexor (striking finger, middle finger of the dominant hand) strikes the pleximeter at the distal interphalangeal joint with a quick, sharp bounce, using a motion that originates from the wrist. Direct chest striking (A, C) or reflex hammers (D) are incorrect. 7. A nurse is preparing to auscultate a client's abdomen for vascular sounds (bruits) and normal bowel sounds. How should the nurse utilize the stethoscope? A. Use the bell for bowel sounds and the diaphragm for bruits. B. Use the diaphragm for bowel sounds (high-pitched sounds) and the bell for bruits (low-pitched vascular sounds). C. Use the bell for both bowel sounds and bruits, pressing firmly. D. Use the diaphragm for both, pressing lightly. Correct Answer: B. Use the diaphragm for bowel sounds (high-pitched sounds) and the bell for bruits (low- pitched vascular sounds). Rationale: Stethoscope diaphragms are designed to detect high-pitched sounds, such as normal breath sounds, normal heart sounds, and bowel sounds; the diaphragm should be pressed firmly against the skin. The stethoscope bell is designed for low-pitched sounds, such as abnormal heart murmurs, S3/S4, and vascular bruits; the bell should be pressed lightly against the skin to avoid flattening the skin, which would turn the bell into a diaphragm. 8. A nurse measures a client's blood pressure using a cuff that is too narrow (too small) for the client's upper arm. How will this technical error affect the blood pressure reading? A. The reading will be falsely low. B. The reading will be falsely high. C. Only the diastolic pressure will be affected. D. The reading will be accurate if the client is sitting. Correct Answer: B. The reading will be falsely high. Rationale: If a blood pressure cuff is too narrow or small, the bladder within the cuff cannot compress the brachial artery effectively. Consequently, the cuff must be inflated to a higher pressure than necessary to occlude the artery, resulting in a falsely elevated (high) reading. Cuffs that are too loose or wide cause falsely low readings (A). 9. The nurse is measuring a client's blood pressure using a standard cuff. If the cuff is too wide (too large) for the client's arm, how will this affect the measurement? A. The reading will be falsely low. B. The reading will be falsely high. C. The reading will be accurate if the arm is kept at heart level. D. The systolic will be high and the diastolic will be low. Correct Answer: A. The reading will be falsely low. Rationale: A blood pressure cuff that is too wide or large distributes the pressure over a larger surface area of the arm, requiring less inflation pressure to compress and occlude the brachial artery. This results in a falsely low reading. Too narrow cuffs cause falsely high readings (B). 10. While deflating the blood pressure cuff, the nurse lets the air out at a rapid rate of 10 mmHg per second. What type of measurement error is likely to occur? A. Falsely high systolic and falsely low diastolic. B. Falsely low systolic and falsely high diastolic. C. Both systolic and diastolic readings will be falsely elevated by 20 mmHg. D. No error will occur if the pulse is regular. Correct Answer: B. Falsely low systolic and falsely high diastolic. Rationale: Standard clinical guidelines dictate deflating the blood pressure cuff at a slow, controlled rate of 2 to 3 mmHg per heart beat (or per second). If the cuff is deflated too rapidly, the nurse may miss the first Korotkoff sound (underestimating systolic, causing a falsely low reading) and may hear the disappearance of sound later than it actually occurred (overestimating diastolic, causing a falsely high reading). 11. A nurse is measuring a client's blood pressure. The client is resting their arm on a high table, placing the brachial artery about 10 cm above the level of the heart. How will this arm position affect the blood pressure reading? A. The reading will be falsely low. B. The reading will be falsely high. C. The position will have no effect on the measurement. D. The diastolic reading will be unaffected. Correct Answer: A. The reading will be falsely low. Rationale: During blood pressure measurement, the client's arm must be supported at heart level (level of the fourth intercostal space). If the arm is positioned *above* the heart level, the hydrostatic pressure of the blood is reduced, causing a falsely low blood pressure reading. If the arm is supported *below* heart level, gravity increases hydrostatic pressure, resulting in a falsely high reading (B). 12. The nurse is preparing to administer digoxin to a client. The nurse notes the client's radial pulse feels irregular. What action should the nurse take to obtain an accurate pulse rate? A. Count the radial pulse for 15 seconds and multiply by 4. B. Auscultate the apical pulse at the fifth intercostal space, midclavicular line, for a full 60 seconds. C. Check the carotid pulse for 30 seconds. D. Trust the reading on the pulse oximeter screen. Correct Answer: B. Auscultate the apical pulse at the fifth intercostal space, midclavicular line, for a full 60 seconds. Rationale: Apical pulse measurement for a full minute (60 seconds) is the standard protocol before administering cardiotonic drugs (like digoxin) or if the peripheral pulse is irregular. Counting for shorter durations (A) can cause the nurse to miss irregularities or miscalculate the rate. Pulse oximeters (D) can be inaccurate in cases of arrhythmias. The apical site is at the mitral area (fifth ICS, MCL). 13. While assessing a client's vital signs, why does the nurse count the client's respiratory rate immediately after checking the pulse, while keeping their fingers placed on the client's radial artery? A. To verify that the radial artery is still pulsing. B. To prevent the client from becoming aware that their breathing is being monitored, which can lead to conscious changes in breathing rate and depth. C. To measure the pulse-to-respiration ratio. D. To save time by doing both tasks simultaneously. Correct Answer: B. To prevent the client from becoming aware that their breathing is being monitored, which can lead to conscious changes in breathing rate and depth. Rationale: Respiration is under both autonomic and voluntary control. If a client is aware the nurse is watching their chest rise and fall, they will often consciously or unconsciously alter their breathing pattern (breathing faster, slower, or deeper). Keeping the hand on the wrist mimics a pulse check, keeping the client relaxed and ensuring a natural, baseline respiratory count. 14. A nurse is selecting the route to measure temperature in an adult client who is confused, mouth- breathing, and recovering from oral surgery. Which route is the most appropriate and accurate? A. Oral route B. Rectal or tympanic route C. Axillary route D. No check is needed because the client has no fever signs. Correct Answer: B. Rectal or tympanic route Rationale: Oral temperature is contraindicated in clients who have had oral surgery, are confused (risk of biting the thermometer), or are breathing through the mouth (causes cool air drafts, giving a falsely low reading). Rectal temperature is the most accurate core temperature route. Tympanic is also suitable. Axillary (C) is the least accurate route and is avoided in adults unless other routes are impossible. 15. A client with severe peripheral vascular disease has very cold fingers. The nurse places a pulse oximeter probe on the index finger. The screen displays an oxygen saturation of 82% with an unstable waveform. What action should the nurse take first? A. Call a code blue immediately. B. Relocate the probe to an alternative, well-perfused site such as the earlobe, nose bridge, or forehead, and check the client's clinical signs of oxygenation. C. Administer 100% oxygen via non-rebreather. D. Warm the oximeter probe in water. Correct Answer: B. Relocate the probe to an alternative, well-perfused site such as the earlobe, nose bridge, or forehead, and check the client's clinical signs of oxygenation. Rationale: Pulse oximetry relies on adequate arterial blood flow (perfusion) to detect light absorption changes. If a client's hands are cold or vaso-constricted (due to peripheral vascular disease), the signal is weak, resulting in inaccurate low readings and erratic waves. The nurse must move the probe to a warmer, more central site (earlobe, nose, forehead) and assess the patient's breathing before escalating. Calling a code (A) or starting high-flow oxygen (C) without validating the reading is inappropriate. Probes must not be wet (D). 16. The nurse is assessing a dark-skinned client for clinical signs of pallor (severe anemia). Which body areas should the nurse inspect to detect this skin change? A. The skin of the chest and abdomen. B. The palpebral conjunctiva, oral mucosa (gums), and nail beds. C. The sclera and hard palate. D. The tips of the ears. Correct Answer: B. The palpebral conjunctiva, oral mucosa (gums), and nail beds. Rationale: In dark-skinned clients, pallor cannot be easily detected on the skin surface due to melanin levels. The nurse must inspect areas with minimal pigmentation, such as the palpebral conjunctiva (should be pink, pale indicates pallor), oral mucosa/gums, and nail beds. Sclera and hard palate (C) are used to assess jaundice. Chest skin (A) is unreliable for dark-skinned clients.
