Diazepam (Valium) is prescribed to a client with alcohol withdrawal. Which of the following statements made by the client indicates an understanding of the treatment regimen?

Correct Answer: C

Rationale: The statement "I'll have my physician lower my dosage once I start to feel okay" indicates an understanding of the treatment regimen because it shows that the client recognizes the need to continue the medication as prescribed and not discontinue it abruptly. It highlights that the client intends to follow up with their physician for appropriate adjustments to the dosage as needed. This demonstrates a responsible approach to managing their alcohol withdrawal with diazepam (Valium).

Correct Answer: C

Rationale: Metoprolol is metabolized primarily by hepatic enzymes in the smooth endoplasmic reticulum via CYP450 pathways.

Correct Answer: D

Rationale: Antibiotics have a maximum dose beyond which efficacy plateaus-more risks toxicity (e.g., ototoxicity), not faster cure, a pharmacodynamic limit. Checking with the doctor delays a clear answer. Interactions aren't the sole issue-toxicity is. Time-based increase lacks basis. Maximum dose explains efficacy ceiling, educating safely.

Correct Answer: C

Rationale: Ace Inhibitors generally end in the suffix "-pril". This class of medications works by inhibiting the angiotensin-converting enzyme (ACE), leading to relaxation of blood vessels and decreased blood pressure. Common examples of ACE inhibitors include enalapril, lisinopril, and captopril.

Correct Answer: C

Rationale: Fat-soluble vitamins (A, D, E, K) are stored in the liver and adipose tissue and excreted slowly, making them more likely to accumulate and cause toxicity if taken in excess. They are not metabolized rapidly (A) and can be stored in the liver (B). They can be toxic (D) if consumed in large amounts.
