Extract:
Question 1 of 5
A nurse is caring for a client who is taking digoxin for heart failure and develops indications of severe digoxin toxicity. Which of the following medications should the nurse prepare to administer?
Correct Answer: D
Rationale: Fab antibody fragments (Digibind or DigiFab) bind to digoxin, neutralizing its effects and treating severe toxicity, which can cause life-threatening arrhythmias.
Question 2 of 5
A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate: 125 mcg = 0.125 mg; 0.125 mg ÷ 0.25 mg/tablet = 0.5 tablets, ensuring the correct digoxin dose.
Question 3 of 5
A nurse is caring for a client who is on warfarin therapy for atrial fibrillation. The client's INR is 5.2. Which of the following medications should the nurse prepare to administer?
Correct Answer: D
Rationale: Vitamin K reverses warfarin's anticoagulant effects by promoting clotting factor synthesis, reducing the high INR of 5.2, which indicates an increased bleeding risk.
Question 4 of 5
A nurse is administering a powdered medication to a client. Which of the following actions should the nurse take first?
Correct Answer: D
Rationale: Checking for allergies first prevents potential allergic reactions, ensuring the medication is safe for the client.
Question 5 of 5
A nurse is teaching a client who has a new prescription for cyclobenzaprine. Which of the following information should the nurse include in the teaching?
Correct Answer: B
