The nurse observes the practical nurse (PN) stroke the lateral side of the sole and across the ball of the foot with the end of a reflex hammer. The client's toes curl downward. Which action should the PN perform next?

Rationale:

A. Clavicle: The clavicle is a bony structure that does not overlie lung tissue, so placing the stethoscope here would not allow auscultation of lung sounds. It is important to position the stethoscope over areas where airflow can be heard clearly.

B. Sternum: The sternum is also a central bony structure and does not provide access to lung fields. Auscultation over the sternum would mainly transmit cardiac sounds, not lung sounds, limiting the assessment of pulmonary function.

C. Lung apex: The apex of the lung, located just above the clavicles, is the correct starting point for auscultation. Beginning at the apex allows the PN to assess airflow in the upper lung fields first and then move systematically downward and posteriorly to compare lung sounds bilaterally, ensuring a thorough respiratory assessment.

D. Aortic site: The aortic site refers to a cardiac auscultation landmark, not a pulmonary field. Placing the stethoscope here is used to assess heart sounds, specifically the aortic valve area, and would not provide reliable information about lung function.

Rationale:

A. Give the client an object to hold: Providing an object is not necessary for assessing basic muscle strength and may interfere with accurately evaluating the client’s ability to perform isolated movements. It is more relevant in functional or fine motor assessments rather than strength testing.

B. Palpate the client's muscle tone: Before testing active movements like flexion, the nurse should assess muscle tone through palpation. This allows the PN to detect hypotonia, hypertonia, or spasticity, which can affect strength testing and provide baseline information about neuromuscular function.

C. Instruct the client to close their eyes: Closing the eyes may be useful for assessing proprioception or coordination but is not essential for evaluating basic upper extremity muscle strength. Vision does not significantly impact isolated strength assessment.

D. Apply resistance to the client's arms: Resistance testing occurs after observing the client’s active movement. Applying resistance prematurely could cause discomfort or injury if the nurse has not first assessed baseline tone and voluntary control of the muscles.
