Question 1 of 5
The nurse is teaching the client prescribed verapamil to avoid which of the following foods?
Correct Answer: A
Rationale: Grapefruit increases verapamil levels by inhibiting metabolism, risking toxicity. Apples, bananas, and oranges have no significant interaction.
Question 2 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 3 of 5
The nurse is screening a client with a new prescription for beta blocker adrenergic propranolol [Inderal LA]. The nurse recognizes that this medication is contraindicated in the presence of which of the following conditions?
Correct Answer: C
Rationale: Propranolol can cause bronchoconstriction, contraindicating it in asthma. It's used for angina, tachycardia, and not affected by gout.
Question 4 of 5
A client with type 1 diabetes is taking propranolol [Inderal], acting confused, and reports weakness and feeling shaky. What must the nurse check first?
Correct Answer: B
Rationale: Propranolol masks hypoglycemia symptoms in type 1 diabetes; confusion and shakiness suggest low glucose, requiring immediate check over renal, BP, or electrolytes.
Question 5 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.
