Question 1 of 5
The nurse is administering sucralfate to a client with stomatitis secondary to chemotherapy. The client wants to take the medication after breakfast. How should the nurse respond?
Correct Answer: D
Rationale: Sucralfate forms a protective barrier over irritated stomach and intestinal areas, requiring an empty stomach for optimal effectiveness. Taking it at least 1 hour before meals ensures proper coating without food interference. Post-meal administration reduces efficacy, and documenting refusal is inappropriate without education.
Question 2 of 5
A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: B
Rationale: Smoking impairs ulcer healing. Reducing to a pack daily is insufficient; quitting is ideal. Monitoring sexual dysfunction, reporting lethargy, and timing with antacids are appropriate.
Question 3 of 5
A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 31
Rationale: Calculate: (500 mL ÷ 240 min) × 15 gtt/mL = 31.25 gtt/min, rounded to 31 gtt/min. This ensures the correct infusion rate for the dextrose solution.
Question 4 of 5
The healthcare provider prescribes propylthiouracil (PTU) and Lugol’s solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?
Correct Answer: B
Rationale: Lugol’s solution reduces thyroid hormone production, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.
Question 5 of 5
The nurse is planning the home care of a client who is receiving a mydriatic medication. Which environment is best for this client?
Correct Answer: A
Rationale: Mydriatics dilate pupils, causing photophobia. A dimly lit room reduces discomfort from light sensitivity. Warm temperatures, humid air, or quiet environments do not address this primary issue.
