Question 1 of 5
Which of the following would the nurse correctly include in client teaching about nitroglycerin (Nitrostat)?
Correct Answer: A,B,C,D
Rationale: Sublingual use, proper storage, timely replacement, and posture precautions ensure nitroglycerin efficacy and safety. Headaches are common and not a reason to stop.
Question 2 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 3 of 5
The nurse is assessing a client who suffers from panic disorder. Which SNRI drug can induce remission and prevent relapse for this disorder?
Correct Answer: A
Rationale: Venlafaxine, an SNRI, is effective for long-term panic disorder management. Escitalopram is an SSRI, alprazolam is short-term, and buspirone is for generalized anxiety.
Question 4 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.

The nurse is assessing therapeutic blood levels for a client receiving lithium (Lithobid). The nurse should recognize which of the following levels as toxic for this drug?
Correct Answer: C
Rationale: Lithium levels of 1.5-2 mEq/L are toxic, requiring intervention. Lower ranges are therapeutic or subtherapeutic.
