Question

When teaching the patient about the signs and symptoms of cardiac glucoside toxicity, the nurse should alert the patient to watch for

a. visual changes such as photophobia.
b. flickering lights or halos around lights.
c. dizziness when standing up.
d. increased urine output.

Answer 1

Patients should be alerted to watch for visual changes like blurred vision or halos around lights as signs of cardiac glucoside toxicity, along with other symptoms like nausea and confusion.

Step-by-step explanation:

When teaching a patient about the signs and symptoms of cardiac glucoside toxicity, the nurse should alert the patient to watch for visual changes such as blurred vision or seeing halos around lights. These symptoms are indicative of toxicity and require immediate attention. While dizziness upon standing might occur, it is more commonly associated with orthostatic hypotension rather than cardiac glucoside toxicity. Moreover, increased urine output is not typically a sign of this toxicity. Patients should also be advised to monitor for other symptoms such as nausea, vomiting, and confusion, which could also indicate toxicity.
