During a skin assessment of an adult client, which finding is considered expected?

Rationale:

A. The dorsalis pedis pulse is palpated on the dorsum (top) of the foot, just lateral to the extensor hallucis longus tendon, between the first and second toes. This pulse represents the continuation of the anterior tibial artery and provides important information about peripheral circulation to the foot and lower extremity. It is frequently assessed in patients with conditions such as peripheral arterial disease, diabetes, or vascular compromise. Assessing the dorsalis pedis pulse helps determine the adequacy of blood flow, detect arterial obstruction, and monitor changes in perfusion over time. A strong, palpable pulse indicates good arterial perfusion, whereas a weak or absent pulse may signal ischemia or arterial blockage, requiring further evaluation.

B. This is the location of the posterior tibial pulse, not the dorsalis pedis. The posterior tibial pulse is palpated behind the medial malleolus (inner ankle) and is also used to assess circulation to the foot, particularly the plantar surface. While both pulses are important in assessing peripheral circulation, they are anatomically distinct.

C. This describes the radial pulse, which is located on the lateral aspect of the wrist near the thumb. The radial pulse is commonly used to assess heart rate, rhythm, and peripheral perfusion to the hand but is not related to the dorsalis pedis pulse or lower extremity circulation.

D. This corresponds to the carotid pulse, which is used to assess central circulation. It is particularly important in emergency situations such as cardiac arrest or shock but does not provide information about peripheral arterial flow in the lower extremities.

Rationale:

A. Allowing the patient to talk during the procedure is incorrect because talking can artificially elevate blood pressure readings. The patient should remain quiet and relaxed to obtain an accurate measurement.

B. Inflating the cuff quickly to 200 mmHg regardless of the patient’s normal blood pressure is incorrect because unnecessarily high inflation can cause discomfort and pain and may increase the risk of vascular injury. Blood pressure should be measured by inflating the cuff 30 mmHg above the patient’s estimated systolic pressure.

C. Wrapping the cuff over clothing is incorrect because clothing can interfere with accurate readings by preventing proper cuff inflation and transmission of pressure. Additionally, the stethoscope should be placed over the brachial artery, not the radial artery, when measuring blood pressure manually.

D. Placing the cuff on the patient’s bare arm, ensuring it is level with the heart, and positioning the stethoscope over the brachial artery is correct. Proper positioning ensures that the cuff compresses the artery evenly, the stethoscope accurately detects Korotkoff sounds, and the reading reflects true blood pressure. Accurate technique involves the patient seated or lying with the arm supported at heart level, cuff size appropriate to arm circumference, inflation above systolic pressure, and slow deflation while listening for the first and last Korotkoff sounds to determine systolic and diastolic pressures.
