Which medication should not be administered with tetracycline?

Correct Answer: D

Rationale: The correct answer is D: Mylanta. Tetracycline can form insoluble complexes with divalent or trivalent cations, such as aluminum, magnesium, calcium, and iron, reducing its absorption and effectiveness. Mylanta contains aluminum and magnesium, which can bind to tetracycline, leading to reduced therapeutic effects. Choices A, B, and C (Ativan, Tylenol, Colace) do not contain cations that interfere with tetracycline absorption.

Correct Answer: C

Rationale: The correct answer is C: Fluconazole. This drug is appropriate for the patient likely suffering from a fungal infection like Candida. Nystatin (A) is also an antifungal but is more commonly used topically. Metronidazole (B) is an antibiotic used for bacterial infections. Acyclovir (D) is an antiviral used for herpes infections. In this case, the patient's symptoms point towards a fungal infection, making Fluconazole the most suitable choice.

Correct Answer: C

Rationale: Rationale: 1. Candida albicans is a type of yeast commonly causing fungal infections. 2. Nystatin is an antifungal medication effective against Candida species. 3. Nystatin works by binding to fungal cell membranes and disrupting their integrity. 4. Griseofulvin (Choice A) is used to treat fungal skin infections, not Candida. 5. Terbinafine (Choice B) is mainly used for dermatophyte infections, not Candida. 6. Caspofungin (Choice D) is more suitable for invasive fungal infections like aspergillosis, not Candida. Summary: - Choice A, B, and D are incorrect because they do not target Candida albicans specifically. - Choice C is correct as nystatin is the appropriate treatment for Candida albicans infections.

Correct Answer: A

Rationale: The correct answer is A: Muscle pain. Statins are known to cause myopathy, a condition characterized by muscle pain or weakness. This is due to statins affecting the production of Coenzyme Q10, which is essential for muscle function. Other choices are incorrect because weight loss is not a common side effect of statins; dizziness is more commonly associated with blood pressure medications or other classes of drugs; and statins are actually used to help lower blood pressure in patients with hypertension, so it is not a common side effect of statins.

Correct Answer: A

Rationale: The correct answer is A because enalapril is an angiotensin-converting enzyme (ACE) inhibitor that works by inhibiting the conversion of angiotensin I to angiotensin II. This leads to vasodilation, decreased aldosterone secretion, and reduced sodium and water retention, ultimately lowering blood pressure. Choices B, C, and D are incorrect because enalapril does not block beta-1 adrenergic receptors, relax vascular smooth muscle directly, or inhibit aldosterone secretion from the adrenal glands.
