The nurse is caring for a patient who is taking a calcium-channel blocker.
What adverse effects would the nurse caution this patient about?

Choice A rationale

While a complete blood count (CBC) is an essential lab value for monitoring many conditions and potential side effects, it is not the primary concern when administering high doses of azithromycin, especially with co-administration of acetaminophen. The focus should be on liver function.

Choice B rationale

Urinalysis is useful in diagnosing and monitoring various conditions but is not directly relevant to monitoring the side effects of azithromycin and acetaminophen. These medications do not typically cause urinary abnormalities that would necessitate frequent urinalysis.

Choice C rationale

Electrolytes are not directly affected by azithromycin and acetaminophen use. Although monitoring electrolytes can be essential in broader contexts, these specific medications do not primarily impact electrolyte balance requiring focused monitoring.

Choice D rationale

Liver enzymes are the key lab values to monitor when administering high doses of azithromycin and acetaminophen. Both medications are metabolized by the liver and can cause hepatotoxicity. Monitoring liver enzymes helps in detecting early signs of liver damage and preventing further complications.

Choice A rationale

While "Drug Facts and Comparisons" is a comprehensive source, it is primarily used by pharmacists rather than nurses. Nurses might find it less practical for their day-to-day needs as it is detailed and more suited to in-depth drug comparisons.

Choice B rationale

A nurse drug guide is designed specifically for nurses and includes practical information for administering medications, understanding side effects, and nursing considerations. It’s tailored to the needs of nursing practice.

Choice C rationale

A drug package insert provides detailed information about a specific drug, including indications, dosage, and side effects. However, it lacks the breadth of information about multiple drugs and nursing considerations compared to a nurse drug guide.

Choice D rationale

The Physician’s Drug Reference (PDR) is an excellent resource but is more suited for physicians. It provides detailed drug information but may not focus on nursing-specific considerations and practical administration advice.
