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 B
Explanation
Choice A rationale:
1 cup of shredded lettuce is low in potassium and is not the best source of potassium for a client with heart failure. While vegetables like lettuce are generally healthy, they do not provide a significant amount of potassium.
Choice B rationale:
1 cup of cantaloupe is the best source of potassium among the given options. Cantaloupe is a fruit that contains a moderate amount of potassium. Including this fruit in the client's diet can help maintain a balanced potassium level, which is important for heart health.
Choice C rationale:
1 oz of tuna is a source of protein but is not particularly rich in potassium. While protein intake is important for overall health, other choices on the list provide more potassium, which is specifically needed for clients with heart failure.
Choice D rationale:
1 cup of raspberries is a good source of fiber and antioxidants, but it is not as rich in potassium as cantaloupe. While raspberries can be a healthy addition to the diet, they are not the best choice for addressing potassium needs in this scenario.
Correct Answer is D
Explanation
The correct answer is Choice D.
Choice A rationale: Ambulation assistance is expected in rehabilitation. It reflects motor recovery needs but does not pose an immediate safety or health risk requiring urgent referral.
Choice B rationale: Difficulty using utensils indicates fine motor deficits. While important for occupational therapy, it’s not a priority compared to airway protection concerns.
Choice C rationale: Expressive aphasia affects communication but does not compromise physical safety or airway integrity. Speech therapy is appropriate but not urgent.
Choice D rationale: Coughing after drinking signals aspiration risk. This can lead to pneumonia or airway obstruction, requiring immediate referral to speech-language pathology for swallow evaluation.
