When administering verapamil by IV, what adverse effect should a nurse monitor for?

1. Hypotension

2. Visual disturbances

3. Dry mouth

4. Insomnia

The correct answer is: Hypotension

When administering verapamil by IV, a nurse should monitor for hypotension as an adverse effect. Verapamil is a calcium channel blocker used to treat hypertension, angina, and cardiac dysrhythmias. It works by relaxing blood vessels and reducing the heart's workload. One common adverse effect of verapamil is hypotension, which can lead to symptoms such as dizziness, lightheadedness, and fainting. Therefore, close monitoring for signs of hypotension is crucial to prevent complications and provide timely intervention if necessary. Visual disturbances, dry mouth, and insomnia are not typically associated with verapamil administration and are not the primary adverse effects to monitor for in this case.
