Question 1 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: B
Rationale: Mydriatic medications dilate pupils, causing light sensitivity. A dimly lit room reduces discomfort from bright light. Quiet environments, warm temperatures, or humid air do not address the primary issue of photophobia.
Question 2 of 5
A female client with a history of peptic ulcer disease receives a prescription for misoprostol. Which information provided by the client indicates to the nurse a need for further teaching?
Correct Answer: A
Rationale: Misoprostol’s administration is not tied to menstrual cycles; it’s used to prevent NSAID-induced ulcers and requires no specific cycle timing. Contacting providers for conception risks, using contraception, and confirming negative pregnancy tests are critical due to teratogenic risks.
Question 3 of 5
A client receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)
Correct Answer: 200
Rationale: Infusion rate = 200 mL ÷ 1 hour = 200 mL/hr. The pump should be set to deliver 200 mL/hr to infuse the entire dose over one hour.
Question 4 of 5
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 37.5
Rationale: Convert 4 grams to 4000 mg. Infusion rate = (300 mg/hr) ÷ (4000 mg/500 mL) = 300 × 500 ÷ 4000 = 37.5 mL/hr. The pump should be set to 37.5 mL/hr.
Question 5 of 5
A client with eczema receives a prescription for betamethasone cream. Which client statement indicates to the nurse that further teaching is needed?
Correct Answer: C
Rationale: Occlusive dressings increase betamethasone absorption, risking side effects like skin thinning, and are not routinely recommended unless prescribed. Using on intact skin, limiting to 2 weeks, and avoiding sunlight are appropriate.
