Question 1 of 5
A female patient who follows a vegetarian diet has recently been prescribed warfarin. She mentions that she consumes leafy green vegetables daily. What should be the nurse’s response?
Correct Answer: C
Rationale: Leafy greens, high in vitamin K, can reduce warfarin’s anticoagulant effect. Informing the provider (
C) ensures dose adjustment. Praising (
A) or assuring enhanced efficacy (
B) ignores the interaction. Substituting vegetables (
D) is unnecessary with proper monitoring.
Question 2 of 5
A client with psychosis is receiving an antipsychotic medication and is continually rubbing the back of the neck. What is the best nursing intervention?
Correct Answer: B
Rationale: Neck rubbing suggests extrapyramidal symptoms (e.g., dystonia) from antipsychotics. Benztropine (
B), an anticholinergic, relieves these symptoms. Pillows (
A), heating pads (
C), and physical therapy (
D) don’t address the cause.
Question 3 of 5
A patient is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The intravenous (IV) administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion?
Correct Answer: 42
Rationale: Infusion rate: 500 mL / 2 hr = 250 mL/hr. Drops per minute: (250 mL/hr × 10 gtt/mL) / 60 min = 41.67, rounded to 42 gtt/min. This ensures accurate delivery of azithromycin.
Question 4 of 5
Before administering the evening dose of carbamazepine, the nurse notes that the patient’s morning carbamazepine level was 84 mcg/mL. What action should the nurse take?
Correct Answer: A
Rationale: Carbamazepine’s therapeutic range is 4-12 mcg/mL; 84 mcg/mL (
A) indicates toxicity risk, requiring provider notification. Administering (
B) or withholding (
C) without consultation is unsafe. Assessing side effects (
D) is secondary to reporting.
Question 5 of 5
A client has been prescribed 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. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numerical value only.)
Correct Answer: 200
Rationale: Infusion rate: 200 mL / 1 hr = 200 mL/hr. The pump should be set to deliver 200 mL/hr to administer ciprofloxacin correctly.
