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?
Correct answer
C
Rationale
The correct answer is C: Move the probe until a whooshing sound is present. When using a Doppler ultrasound stethoscope to assess pedal pulses in a client with peripheral vascular disease, the nurse should move the probe until a whooshing sound, known as the Doppler signal, is heard. This sound indicates blood flow through the vessel, helping to identify the presence and strength of the pulse. This technique ensures accurate assessment of the pedal pulses in clients with peripheral vascular disease.
Explanations for why the other choices are incorrect:
A: Exert firm pressure when placing the probe - Firm pressure can distort the signal and affect the accuracy of the assessment.
B: Apply the probe to the exterior aspect of the ankle - The probe should be placed over the pulse point for accurate assessment, not just on the exterior aspect of the ankle.
D: Hold the probe at a 30┬░ angle to the blood vessel - Holding the probe at a specific angle is not necessary for assessing pedal
