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. A client has a new prescription for Ramelteon and is receiving teaching from a nurse. The nurse should instruct the client to avoid which of the following foods while taking this medication?

• A. Baked potato
• B. Fried chicken
• C. Whole-grain bread
• D. Citrus fruits

Correct answer: B

Rationale: The correct answer is B: Fried chicken. High-fat foods like fried chicken can prolong the absorption of Ramelteon, potentially reducing its effectiveness. It is important to avoid such foods to ensure the medication works as intended.

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

• A. Take the medication with food.
• B. Monitor your blood pressure weekly.
• C. Notify your provider if you develop a persistent cough.
• D. Avoid using salt substitutes to prevent hyperkalemia.

Correct answer: C

Rationale: Clients prescribed with Captopril, an ACE inhibitor, are at risk of developing a persistent cough as a common adverse effect. It is essential for the client to inform their healthcare provider promptly if this side effect occurs to evaluate the need for a medication change or adjustment.

4. A client has a new prescription for Brimonidine ophthalmic drops and wears soft contact lenses. Which of the following instructions should the nurse include in the teaching?

• A. This medication can stain your contacts.
• B. This medication can cause your pupils to constrict.
• C. This medication can absorb into your contacts.
• D. This medication can slow your heart rate.

Correct answer: C

Rationale: The correct answer is C. Brimonidine can absorb into soft contact lenses. To prevent this, the client should remove their contacts, instill the medication, and wait at least 15 minutes before putting the contacts back in to avoid potential absorption of the medication by the lenses. Choices A, B, and D are incorrect because Brimonidine's main concern with contact lenses is its absorption into the lenses rather than staining contacts, causing pupil constriction, or affecting heart rate.

5. A healthcare provider is preparing to administer metoprolol to a client. Which of the following findings should the provider identify as a contraindication to receiving this medication?

• A. Bradycardia
• B. Hypertension
• C. Fever
• D. Rash

Correct answer: A

Rationale: Metoprolol, a beta-blocker, is contraindicated in clients with bradycardia as it can further lower the heart rate, potentially leading to more serious complications. Bradycardia is defined as a heart rate below 60 beats per minute, and administering metoprolol in such cases can exacerbate this condition, causing adverse effects on cardiac output. Hypertension, fever, and rash are not contraindications for metoprolol administration.
