Nursing Elites

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. A client has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?

• A. Take this medication in the morning.
• B. Consume foods rich in potassium.
• C. Take this medication with a meal.
• D. Monitor for signs of dehydration.

Correct answer: D

Rationale: Hydrochlorothiazide is a diuretic that can lead to dehydration due to increased urination. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. It is essential to educate the client to monitor these signs and seek medical attention if they occur. Choice A is incorrect because Hydrochlorothiazide is usually taken in the morning to prevent disruption of sleep due to increased urination during the night. Choice B is incorrect because while Hydrochlorothiazide can lead to potassium loss, consuming foods rich in potassium is not a specific instruction related to this medication. Choice C is incorrect because taking Hydrochlorothiazide with a meal is not a specific requirement for its administration.

3. Which part of the body requires a continuous supply of oxygen and vital nutrients to support life and death?

• A. Liver
• B. Kidneys
• C. Brain
• D. Muscles

Correct answer: C

Rationale: The brain requires a continuous supply of oxygen and vital nutrients to support life and prevent death. Oxygen and nutrients are essential for brain function, and any interruption in the supply can lead to serious consequences, including brain damage or death. Therefore, ensuring a constant flow of oxygen and nutrients to the brain is vital for survival and overall health.

4. Which of the following is the antidote for benzodiazepine toxicity?

• A. Flumazenil
• B. Methylene blue
• C. Deferoxamine
• D. Alkalinize urine

Correct answer: A

Rationale: Flumazenil is the specific antidote for benzodiazepine toxicity. It acts as a competitive antagonist at the benzodiazepine binding site on the GABA receptor, reversing the sedative effects of benzodiazepines. Administration of flumazenil is indicated in cases of benzodiazepine overdose or toxicity to rapidly reverse the central nervous system depression caused by these drugs. It is important to note that flumazenil should be used cautiously in patients with a history of seizures or those who are physically dependent on benzodiazepines, as it can precipitate withdrawal symptoms or seizures.

5. Which drug classes are NOT typically used to treat angina?

• A. Calcium channel blockers
• B. Organic nitrates
• C. Alpha blockers
• D. Beta blockers

Correct answer: C

Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.
