Question 1 of 5
A client has been diagnosed with a life-threatening recurrent ventricular fibrillation that has not responded to other medications or defibrillation. Which of the following does the nurse anticipate will be prescribed next?
Correct Answer: D
Rationale: Amiodarone is a potent antiarrhythmic used for refractory ventricular fibrillation when other treatments fail. Quinidine is less effective for this, digoxin treats heart failure/atrial issues, and atropine is for bradycardia.
Question 2 of 5
A c+2:34lient has a medical prescription for nifedipine [Adalat XL]. Which of the following should the nurse teach the client about this medication?
Correct Answer: A
Rationale: Nifedipine [Adalat XL] is an extended-release calcium channel blocker that must be swallowed whole to maintain its controlled release properties. Monitoring BP, OTC cautions, and timing are not specific teaching priorities for this formulation.
Question 3 of 5
Which of the following is the federal statute that regulates drugs and medications in Schedules I through V?
Correct Answer: C
Rationale: The Controlled Substances Act (CS
A) governs the regulation of drugs in Schedules I-V based on abuse potential. CDC, HIPAA, and FDA have different roles.
Question 4 of 5
The nurse is monitoring the aPTT level for an assigned client. Which of the following medications requires this type of laboratory monitoring?
Correct Answer: D
Rationale: Heparin requires aPTT monitoring to ensure therapeutic anticoagulation. Clopidogrel, warfarin (INR), and enoxaparin don't use aPTT.
Question 5 of 5
The nurse is preparing to administer enoxaparin (Lovenox) to a client before hip replacement surgery. Which of the following conditions would prevent the nurse from administering this drug?
Correct Answer: B
Rationale: A bleeding disorder contraindicates enoxaparin due to hemorrhage risk. It's used for DVT/PE prevention, and a HR of 60 is normal.
