A. Nifedipine [Adalat XL] is a long-acting calcium channel blocker, and it should be swallowed whole to maintain its extended-release properties and ensure proper absorption.
B. Blood pressure should be monitored regularly, but taking it in the morning is not specifically related to nifedipine's use.

B. Captopril (Capoten) is an ACE inhibitor and is not associated with visual disturbances like halos.
C. Verapamil (Calan) is a calcium channel blocker and does not typically cause visual symptoms such as halos.
D. Digoxin (Lanoxin) toxicity can lead to visual disturbances, including blurry vision and seeing yellow/green halos, which are classic signs of toxicity.

A. Adding another drug is premature; fluoxetine may need more time to show effects.
B. While some antidepressants may show effects in 1-3 weeks, fluoxetine typically requires a full 4-6 weeks to demonstrate its therapeutic effects.
C. Switching to another antidepressant after only one week may be premature; fluoxetine often takes longer to be effective.

B. Both ACE inhibitors and ARBs are used to treat heart failure, not just ACE inhibitors.
C. Both ARBs and ACE inhibitors can affect potassium levels, and ACE inhibitors can impact white blood cell counts. Monitoring is required.
D. Both ARBs and ACE inhibitors are contraindicated during pregnancy due to potential risks to the fetus, such as renal damage and other complications.

A. Lithium is a mood stabilizer specifically used to treat acute mania and stabilize mood in bipolar disorder.
B. Diazepam (Valium) is used for anxiety management, not for treating acute mania.
C. Bupropion (Wellbutrin) is an antidepressant that is not typically used for treating acute mania.
D. Paroxetine (Paxil) is an antidepressant used for depression and is not indicated for treating acute mania.

1. Convert micrograms to milligrams:
   • 750 mcg = 0.75 mg
2. Calculate the number of pills:
   • 0.75 mg / 0.25 mg/tablet = 3 tablets

Therefore, the nurse should administer 3 tablets of digoxin.
