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 with a prescription for Vasopressin to treat Diabetes Insipidus is being taught by a healthcare professional. Which of the following client statements indicates an understanding of the teaching?

• A. I will reduce my sodium intake.
• B. I should increase my water intake.
• C. I will notify my doctor if I develop chest pain.
• D. I should take this medication with food.

Correct answer: C

Rationale: The correct answer is C because Vasopressin can cause vasoconstriction, potentially leading to chest pain. It is crucial for the client to inform their healthcare provider immediately if they experience chest pain while on Vasopressin therapy to address any potential cardiovascular complications promptly. Choices A, B, and D are incorrect. While maintaining adequate hydration is essential with Vasopressin therapy due to its antidiuretic effect, increasing water intake is not the most critical aspect to monitor. Reducing sodium intake may be beneficial in some cases but is not directly related to the potential side effects of Vasopressin. Taking the medication with food is not a specific instruction for Vasopressin administration.

3. During discharge instructions, a client with a new prescription for Phenytoin should be advised to take which of the following actions?

• A. Brush and floss your teeth regularly.
• B. Avoid drinking grapefruit juice.
• C. Take this medication on an empty stomach.
• D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct instruction for a client with a new prescription for Phenytoin is to brush and floss their teeth regularly. Phenytoin is known to cause gingival hyperplasia, a condition that affects the gums. By maintaining good oral hygiene practices such as regular brushing and flossing, the client can help minimize the risk of developing this side effect. Choices B, C, and D are incorrect. Avoiding grapefruit juice is more relevant for medications affected by grapefruit juice metabolism, taking medication on an empty stomach is not specifically indicated for Phenytoin, and increasing calcium-rich foods is not directly related to the side effects or administration of Phenytoin.

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

• A. Take this medication on an empty stomach.
• B. Take this medication with food.
• C. Take this medication at bedtime.
• D. Take this medication with antacids.

Correct answer: A

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, leading to reduced effectiveness of the medication.

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

• A. Take this medication with food.
• B. Avoid dairy products while taking this medication.
• C. Take this medication at bedtime.
• D. Increase your intake of vitamins.

Correct answer: A

Rationale: The correct instruction for a client prescribed Nitrofurantoin is to take the medication with food. Taking Nitrofurantoin with food helps enhance absorption and reduces the risk of gastrointestinal side effects. It is important for the nurse to emphasize this instruction to ensure the client benefits optimally from the medication. Choices B, C, and D are incorrect. Avoiding dairy products is not specifically required with Nitrofurantoin. Taking the medication at bedtime is not a standard instruction. Increasing vitamin intake is not necessary in relation to Nitrofurantoin therapy.
