Sample questions from Lehne's Pharmacology Nursing Care 12TH Edition Study Guide

This material has 20 questions with answers and rationales. Here are the first 5.

1. 1.A client receiving intravenous morphine is difficult to arouse. Respirations are 7/min and shallow; oxygen saturation is 96% on supplemental oxygen. Which action is the priority?

   • A.Document adequate oxygenation and reassess in 30 minutes.
   • B.Stop opioid administration, summon help, and support ventilation while preparing naloxone per protocol.
   • C.Ask the client to rate pain before making any medication change.
   • D.Increase supplemental oxygen without further assessment.

   Rationale: B is correct because the client has clinically significant respiratory depression requiring immediate airway and ventilation support and protocol-directed reversal. A delays necessary treatment and mistakes oxygenation for ventilation. C places a routine pain rating ahead of stabilization. D may improve oxygen saturation but does not correct inadequate ventilation or the drug effect.

2. 2.A client taking warfarin says, 'I have stopped eating spinach and broccoli completely.' Which response is best?

   • A.Keep vitamin K intake reasonably consistent and follow the prescribed INR testing schedule.
   • B.Take an extra warfarin tablet whenever you eat a green vegetable.
   • C.Replace vegetables with an herbal supplement.
   • D.That is necessary because any vitamin K makes warfarin ineffective.

   Rationale: C is correct because consistent vitamin K intake supports stable anticoagulation. A incorrectly requires complete avoidance of nutritious foods. B introduces potential interactions without benefit. D recommends unsafe self-adjustment that could cause bleeding.

3. 3.Before administering digoxin, the nurse finds an apical pulse of 46/min, new nausea, potassium 2.8 mEq/L, and worsening renal function. What should the nurse do?

   • A.Administer the dose because nausea is an expected harmless effect.
   • B.Give the drug with food and repeat the pulse tomorrow.
   • C.Withhold digoxin and obtain urgent clinical evaluation with rhythm assessment.
   • D.Administer an additional potassium-sparing diuretic independently.

   Rationale: D is correct because bradycardia, nausea, hypokalemia, and impaired clearance strongly suggest an unsafe response and possible toxicity. A and B expose the client to further harm and delay assessment. C is outside independent prescribing authority and does not safely address the rhythm disturbance.

4. 4.An alert client with diabetes has a glucose of 58 mg/dL and can swallow safely. Which intervention is most appropriate initially?

   • A.Give a large high-fat meal and recheck glucose in two hours.
   • B.Keep the client NPO until the prescriber rounds.
   • C.Administer scheduled rapid-acting insulin.
   • D.Give 15 g of rapid-acting carbohydrate and recheck glucose in 15 minutes according to protocol.

5. 5.A client taking lisinopril develops swelling of the tongue and difficulty swallowing. Which action has the highest priority?

   • A.Schedule a routine follow-up visit.
   • B.Offer ice water and monitor for resolution.
   • C.Prepare to administer the next dose with food.
   • D.Activate emergency assistance and assess and protect the airway.
