Question 1 of 5

A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for the nurse to provide this client?

Correct Answer: D

Rationale: Isotretinoin is highly teratogenic, causing severe birth defects. Discontinuing 1 month before conception (
D) is critical. Breastfeeding (
A) and liver tests (
B) are secondary. Vitamin A (
C) avoidance is relevant but less urgent. Note: Explanation suggests D was intended.

Question 2 of 5

The healthcare provider prescribes the antibiotic tetracycline HCl for an adult client that arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?

A. Protect the skin from sunlight while taking the drug. B. Take with orange juice to enhance GI absorption. C. Return to the clinic weekly to obtain serum drug levels. D. Take with milk or antacids to prevent gastrointestinal (GI) irritation.

Correct Answer: A

Rationale: Tetracycline causes photosensitivity, increasing sunburn risk, so sun protection (
A) is essential (matches 55-Q9/22). Orange juice (
B) contains calcium, impairing absorption. Weekly drug level checks (
C) are not required. Milk/antacids (
D) reduce absorption by chelating tetracycline.

Question 3 of 5

A female client who is a vegetarian has a new prescription for warfarin. The client states she eats leafy green vegetables every day. How should the nurse respond?

A. Suggest that the client replace the leafy vegetables with a protein source such as nuts or beans. B. Commend the client for her healthy lifestyle and encourage her to continue her current diet habits. C. Advise the client that the healthcare provider needs to be made aware of her current diet. D. Confirm that her diet choices will help the medication be more effective in preventing blood clots.

Correct Answer: C

Rationale: Leafy greens, high in vitamin K, reduce warfarin’s anticoagulant effect (
C) (matches 55-Q46). Informing the provider ensures dose adjustment. Substituting vegetables (
A) is unnecessary. Praising (
B) or claiming enhanced efficacy (
D) ignores the interaction.

Question 4 of 5

The nurse is planning to administer the antiulcer gastrointestinal (GI) agent sucralfate to a client with peptic ulcer disease. Which action should the nurse include in this client's plan of care?

A. Give sucralfate on an empty stomach. B. Assess for secondary Candida infection. C. Administer sucralfate once a day, preferably at bedtime. D. Monitor for electrolyte imbalance.

Correct Answer: A

Rationale: Sucralfate forms a protective barrier over ulcers and should be given on an empty stomach (
A), 1 hour before meals or at bedtime (matches 55-Q10). Candida infection (
B) and electrolyte imbalances (
D) are not associated. Once-daily dosing (
C) is incorrect; it’s typically 4 times daily.

Question 5 of 5

The nurse is preparing a discharge teaching plan for a client who is taking ciprofloxacin hydrochloride tablets, which were prescribed because of a suspected anthrax exposure. Which instruction(s) should be included in the teaching plan?

A. Crush and mix the tablets with pudding if you have trouble swallowing the tablets. B. Report any tendon pain or swelling to the healthcare provider immediately. C. Increase fluid intake while taking the medication. D. Use nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve mild joint aches and pains caused by the medication. E. Limit exposure to sunlight and avoid tanning beds.

Correct Answer: B,C,E

Rationale: Ciprofloxacin requires reporting tendon pain (
B) due to rupture risk, high fluid intake (
C) to prevent crystalluria, and sun protection (E) due to photosensitivity (matches 55-Q24). Crushing tablets (
A) alters release. NSAIDs (
D) increase seizure risk.
