Question 1 of 5
The nurse explains that is regard to regulation by the Dietary Supplement Health and Education Act, dietary supplements:
Correct Answer: A
Rationale: The correct answer is A because under the Dietary Supplement Health and Education Act, dietary supplements do not have to demonstrate effectiveness before being marketed. This is a key distinction from prescription drugs, which must undergo rigorous testing to prove their effectiveness. The Act allows manufacturers to market supplements without FDA approval as long as they do not claim to prevent, treat, or cure specific diseases.
Choices B, C, and D are incorrect because dietary supplements are not required to be proven safe, checked for label accuracy, or tested before being marketed. This lack of pre-market approval for effectiveness is a notable feature of the regulation of dietary supplements under the Act.
Question 2 of 5
Which of the following would reduce the absorption of ciprofloxacin?
Correct Answer: D
Rationale: The correct answer is D: Antacids or mineral supplements. Antacids containing calcium, magnesium, or aluminum and mineral supplements containing iron or zinc can bind to ciprofloxacin, reducing its absorption in the GI tract. This interaction can decrease the effectiveness of ciprofloxacin in treating infections. Alcohol (choice
A) does not directly affect ciprofloxacin absorption. Intense physical exertion (choice
B) does not have a significant impact on ciprofloxacin absorption. Fruit juices, especially grapefruit juice (choice
C), can interact with certain medications, but not specifically with ciprofloxacin.
Therefore, the correct choice is D because antacids and mineral supplements can interfere with ciprofloxacin absorption.
Question 3 of 5
The nurse is instructing a client who has been prescribed tetracycline (Sumycin). What should the nurse advise this client to avoid while taking this medication?

Rationale: The correct answer is B: Sunlight. Tetracycline can cause photosensitivity, leading to severe sunburns and skin damage. The nurse should advise the client to avoid prolonged exposure to sunlight and to use sunscreen. Green leafy vegetables (
A), exercise (
C), and foods high in tyramine (
D) are not contraindicated with tetracycline. Green leafy vegetables are a good source of nutrients, exercise is beneficial for overall health, and tyramine-rich foods are typically avoided with other medications like MAOIs.
Question 4 of 5
Which of the following drugs inhibit bacterial beta-lactamase?
Correct Answer: D
Rationale: The correct answer is D: Zosyn (piperacillin/tazobactam). Piperacillin is a beta-lactam antibiotic susceptible to beta-lactamase degradation. Tazobactam is a beta-lactamase inhibitor that protects piperacillin from degradation, enhancing its antibacterial activity. Goldenseal (
A) is an herb with no known beta-lactamase inhibitory properties. Ceftriaxone (
B) and Penicillin (
C) are beta-lactam antibiotics but do not inhibit beta-lactamase.
