Question

you are assessing an unresponsive patient known to have an implanted left ventricular assist device (lvad). the patient is not breathing, the patients skin is pale and cool, and capillary refill is inadequate. how do you assess whether the lvad is functioning? choose the correct answer assess the carotid pulse auscultate for heart sounds listen for device hum measure blood pressure with a large cuff

Explanation:

In patients with an implanted LVAD, the device typically produces a characteristic hum when functioning properly. Assessing the carotid pulse may be inaccurate as LVADs can alter normal arterial pulsations. Auscultating for heart sounds may not be reliable due to the LVAD's influence. Measuring blood - pressure with a large cuff may not accurately reflect LVAD function.

Answer:

Listen for device hum
