Nursing Elites

1. Potassium-sparing diuretics primarily affect which part of the kidney?

• A. Proximal convoluted tubule
• B. Loop of Henle
• C. Collecting duct
• D. Distal convoluted tubule

Correct answer: D

Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.

2. Which of the following is not a side effect of loop diuretics?

• A. Alkalosis
• B. Nausea
• C. Hypotension
• D. Potassium deficits

Correct answer: B

Rationale: Nausea is not commonly associated with loop diuretics. Loop diuretics are known to cause electrolyte imbalances such as potassium deficits, metabolic alkalosis, and hypotension due to excessive fluid loss. Nausea is not a typical side effect of loop diuretics.

3. A client has a new prescription for Sucralfate to treat a duodenal ulcer. Which of the following instructions should be included?

• A. Take the medication with meals.
• B. Swallow the tablet whole.
• C. Take the medication 1 hour before meals.
• D. Chew the tablet before swallowing.

Correct answer: C

Rationale: The correct instruction for taking Sucralfate is to take it 1 hour before meals. This timing allows the medication to coat the stomach lining, providing a protective barrier against stomach acid, which aids in healing the duodenal ulcer. Option A is incorrect as it contradicts the correct timing for taking Sucralfate. Option B is not necessary as it does not pertain to how the medication should be taken in relation to meals. Option D is incorrect as chewing the tablet before swallowing is not the correct administration method for Sucralfate.

4. A client has a new prescription for atenolol. Which of the following findings should the nurse instruct the client to monitor for as an adverse effect of this medication?

• A. Tachycardia
• B. Hypoglycemia
• C. Bradycardia
• D. Hypertension

Correct answer: C

Rationale: The correct answer is 'C: Bradycardia.' Atenolol, a beta-blocker, commonly causes bradycardia as an adverse effect. It works by slowing down the heart rate, which can lead to a decreased heart rate known as bradycardia. Monitoring for signs of bradycardia is essential to prevent any potential complications while on atenolol. Choices A, B, and D are incorrect because atenolol is not known to cause tachycardia, hypoglycemia, or hypertension as common adverse effects.

5. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take one tablet at the first sign of chest pain.
• B. If pain is not relieved, take another tablet in 10 minutes.
• C. You can take up to five tablets in 15 minutes.
• D. Swallow the tablet with water.

Correct answer: A

Rationale: The correct instruction for a client with a new prescription for nitroglycerin sublingual tablets is to take one tablet at the first sign of chest pain. If the pain is not relieved after 5 minutes, the client should call 911 and take a second tablet. Taking more than the recommended dose can lead to serious side effects, and swallowing the tablet would not provide the rapid effect needed in cases of chest pain. Choice A is correct because it aligns with the standard protocol for nitroglycerin use in treating angina. Choice B is incorrect as the second tablet should be taken after 5 minutes, not 10 minutes. Choice C is incorrect as taking up to five tablets in 15 minutes is excessive and can result in serious complications. Choice D is incorrect as nitroglycerin sublingual tablets should be placed under the tongue for rapid absorption, not swallowed.
