RN HESI Pharmacology Exam 3 Questions
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 be set to deliver 200 mL/hr to infuse the entire dose over one hour.
Question 2 of 5
A client receives a prescription for penicillin 2 million units IM. The available vial is labeled, '600,000 units/2 mL.' How many mL should the nurse administer? (Enter numeric value only.)
Correct Answer: 4
Rationale:
To calculate: (2,000,000 units prescribed) ÷ (600,000 units/2 mL) = 2,000,000 × 2 ÷ 600,000 = 4 mL. The nurse should administer 4 mL to deliver the prescribed 2 million units.
Question 3 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: D
Rationale: Fluticasone/salmeterol is a maintenance therapy, not for acute asthma attacks, and should be used no more than twice daily to avoid side effects like oral thrush. Exhaling into the discus risks clumping the powder, and hypotension is not a common side effect.
Question 4 of 5
A female client starts a new prescription, oxybutynin, for symptoms of an overactive bladder. The client tells the nurse that she is training to run a half-marathon. Which Instruction should the nurse emphasize?
Correct Answer: D
Rationale: Oxybutynin’s anticholinergic effects reduce sweating, increasing dehydration and overheating risks during marathon training. Emphasizing hydration and heat precautions is critical. Bruising, infections, or sun injury are less relevant concerns.
Question 5 of 5
The nurse observes that a client has become lethargic 30 minutes after receiving an opioid injection for pain. Which vital sign should the nurse obtain first?
Correct Answer: D
Rationale: Opioids can cause respiratory depression, a life-threatening side effect presenting as lethargy. Assessing respiratory rate first identifies slowed breathing, guiding urgent interventions like naloxone. Pulse, blood pressure, or temperature are secondary concerns.
