Q

hich of the following patients would most likely need to use a rating of perceived exertion scale when self-monitoring exercise intensity?

a patient taking diuretics
a patient with neuropathy in the hands
a patient with coronary artery disease
a patient with bradycardia

A

Correct Answer: a patient with neuropathy in the hands

A patient with neuropathy in the hands would likely have sensory loss and therefore would have difficulty palpating a pulse to self-monitor exercise intensity.
