1. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?

A. Sodium phosphate
B. Psyllium
C. Bisacodyl
D. Polyethylene glycol

Correct answer: A

Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.

2. What is a common side effect that typically occurs with the initial therapy of Nitroglycerine as a result of increased vasodilation?

A. Abdominal cramps
B. Calf pain
C. Headache
D. Blurred vision

Correct answer: C

Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.

3. A client has a new prescription for Metoprolol to treat hypertension. Which of the following instructions should the nurse include?

A. Stop taking the medication if your heart rate is below 70/min.
B. Take the medication with food.
C. Avoid sudden changes in position.
D. Increase your fluid intake while taking this medication.

Correct answer: C

Rationale: The correct instruction for a client starting Metoprolol is to avoid sudden changes in position. Metoprolol can cause orthostatic hypotension, leading to dizziness and falls if the client changes positions quickly. By advising the client to make position changes slowly, the nurse helps prevent these adverse effects and promotes safety.

4. What is a desired outcome of the drug Phenytoin?

A. Decrease symptoms of PTSD
B. Resolution of signs of infection
C. Decrease or cessation of seizures without excessive sedation
D. Prevention or relief of bronchospasm

Correct answer: C

Rationale: The correct answer is C: Decrease or cessation of seizures without excessive sedation. Phenytoin is primarily used as an antiepileptic medication to manage and prevent seizures. It does not directly impact symptoms of PTSD (Choice A), resolution of signs of infection (Choice B), or prevention or relief of bronchospasm (Choice D). Therefore, the desired outcome of Phenytoin is to control seizures effectively while avoiding excessive sedation.

5. Which of the following is considered a class IA Sodium Channel blocker?

A. Mexiletine
B. Amiodarone
C. Quinidine
D. Procainamide

Correct answer: D

Rationale: Procainamide is a class IA antiarrhythmic drug that acts as a sodium channel blocker by blocking fast sodium channels. Mexiletine is a class IB antiarrhythmic drug, not class IA. Amiodarone is a class III antiarrhythmic, and Quinidine is a class IA antiarrhythmic but not a sodium channel blocker.
