A nurse is using a Doppler ultrasound stethoscope to assess the pedal pulses of a client who has peripheral vascular disease. Which of the following actions should the nurse plan to take?
Exert firm pressure when placing the probe.
Apply the probe to the exterior aspect of the ankle.
Move the probe until a whooshing sound is present.
Hold the probe at a 30° angle to the blood vessel.
The Correct Answer is C
Choice A rationale:
Exerting firm pressure when placing the probe (Choice A) is not recommended because it can potentially compress the blood vessels and impede blood flow. This can lead to inaccurate readings and compromise the assessment of the pedal pulses in a client with peripheral vascular disease.
Choice B rationale:
Applying the probe to the exterior aspect of the ankle (Choice B) is not the standard approach for assessing pedal pulses. The pedal pulses are typically assessed on the dorsal (top) and posterior (back) aspects of the foot, as well as the lateral (side) aspects of the ankle. Placing the probe on the exterior aspect of the ankle might not yield accurate results.
Choice C rationale:
Moving the probe until a whooshing sound is present (Choice C) is the correct action when using a Doppler ultrasound stethoscope to assess pedal pulses. The whooshing sound, known as "Doppler sound," indicates the presence of blood flow. The nurse should gently maneuver the probe until this sound is heard, allowing for an accurate assessment of the pulses and blood flow status.
Choice D rationale:
Holding the probe at a 30° angle to the blood vessel (Choice D) is not a standard practice for assessing pedal pulses with a Doppler ultrasound stethoscope. The nurse should place the probe directly over the pulse site and adjust its position until the Doppler sound is detected.

Correct Answer is A
Explanation
The correct answer is choice A. 30° lateral.
Choice A rationale:
The 30° lateral position is recommended to reduce pressure on the client’s bony prominences. This position helps distribute the client’s weight more evenly and reduces the risk of pressure injury formation.
Choice B rationale:
The lateral semi-prone recumbent position may not be as effective in reducing pressure on bony prominences as the 30° lateral position. It could potentially increase pressure on certain areas, depending on the client’s body shape and condition.
Choice C rationale:
The supine position can increase pressure on the sacrum and heels, which are common sites for pressure injuries. Therefore, it is not the best position for a client at risk for pressure injury formation.
Choice D rationale:
The 45° supported Fowler’s position can increase pressure on the sacrum and ischial tuberosities, another common site for pressure injuries. Therefore, it is not the most effective position for reducing pressure on bony prominences for a client at risk for pressure injury formation.
Correct Answer is C
Explanation
Choice A rationale:
The walking gait test is used to assess a client's walking pattern and balance, particularly for identifying abnormalities in gait. However, it doesn't specifically evaluate sensory functions, making it an inappropriate choice for this scenario.
Choice B rationale:
The plantar reflex test, also known as the Babinski reflex test, assesses the neurological integrity of the corticospinal tract. It involves stimulating the sole of the foot to elicit specific reflex movements. While this test is important in assessing neurological function, it doesn't directly evaluate sensory functions as requested in the question.
Choice C rationale:
The finger-to-nose test is a part of the neurological examination used to assess a client's coordination and proprioception. In this test, the client is asked to touch their nose with their index finger while alternating between eyes closed and eyes open. This evaluates their ability to sense the position of their limbs in space (proprioception) and their coordination. It directly addresses the focus of the question, making it the correct choice.
Choice D rationale:
The Romberg test evaluates a client's balance and proprioception. It involves having the client stand with their feet together and their eyes closed to assess their ability to maintain balance without visual input. While this test is relevant to sensory functions, it primarily assesses proprioception and balance rather than coordination, which the question is specifically targeting.
