A patient has been prescribed oral tetracycline for the treatment of acne. Which of the following must the nurse include in the patient teaching plan?
Take the drug on an empty stomach.
Take the drug along with a meal.
Take the drug along with milk or fruit juice.
Take the drug immediately after meals.
The Correct Answer is A
A. Take the drug on an empty stomach is correct because tetracycline should be taken without food for optimal absorption, ideally 1 hour before or 2 hours after meals.
B. Take the drug along with a meal is incorrect as it can reduce the absorption of tetracycline.
C. Take the drug along with milk or fruit juice is incorrect because calcium and magnesium can bind to tetracycline, decreasing its effectiveness.
D. Take the drug immediately after meals is also incorrect as food can hinder absorption, making this timing ineffective for treatment.

Correct Answer is C
Explanation
A. Metformin does not stimulate the pancreas to produce more insulin; that action is characteristic of sulfonylureas.
B. Metformin does not increase the absorption of glucose in the intestines; rather, it works by reducing the amount of glucose released into the bloodstream.
C. Metformin primarily decreases glucose production in the liver and improves insulin sensitivity in peripheral tissues, which helps lower blood sugar levels. This makes it effective for managing type 2 diabetes.
D. While metformin can have effects on fat metabolism, its primary action is not to decrease fat breakdown but to manage blood glucose levels.
Correct Answer is A
Explanation
A. Acetaminophen is primarily an analgesic and antipyretic; it does not have anti-inflammatory properties, so it will not reduce swelling or inflammation.
B. While some medications may take time to show effects, this is not applicable to acetaminophen regarding inflammation, as it does not address that symptom.
C. Although acetaminophen is used for pain relief, saying it has only clinical use for pain is misleading; it is not effective for inflammation.
D. Monitoring for bleeding is important for medications that can affect coagulation, such as NSAIDs, but acetaminophen does not typically cause this risk.
