Question 1 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 deliver 200 mL/hr to infuse the entire dose over one hour.
Question 2 of 5
A client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?
Correct Answer: D
Rationale: Metronidazole with alcohol causes a disulfiram-like reaction (flushing, nausea). Avoiding alcohol during and 48 hours post-treatment is critical. Refrigeration, specific water intake, or post-meal dosing are not required.
Question 3 of 5
A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?
Correct Answer: A
Rationale: Tamsulosin, an alpha-blocker, can cause orthostatic hypotension. Monitoring blood pressure detects this adverse reaction. Urine output, weights, or bladder scans assess BPH symptoms, not tamsulosin’s side effects.
Question 4 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 5 of 5
To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?
Correct Answer: B
Rationale: Fluticasone/salmeterol is for maintenance, used twice daily maximum to avoid side effects. Rapid exhalation, acute attack use, or hypotension are incorrect.
