Nursing Elites

1. Which electrolyte imbalance is a common concern for patients on loop diuretics?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A, Hypokalemia. Loop diuretics can lead to potassium loss, resulting in hypokalemia. This imbalance is a common concern because potassium plays a vital role in various physiological functions, including maintaining proper heart function. Choices B, C, and D are incorrect because loop diuretics typically do not cause hyperkalemia, hyponatremia, or hypercalcemia.

2. A healthcare provider is reviewing the laboratory report of a client with a prescription for digoxin. Which result requires withholding the medication?

• A. Digoxin 0.8 ng/mL
• B. Sodium 145 mEq/L
• C. BUN 20 mg/dL
• D. Potassium 3.1 mEq/L

Correct answer: D

Rationale: The correct answer is D. A low potassium level (3.1 mEq/L) can increase the risk of digoxin toxicity. Hypokalemia can potentiate the effects of digoxin on the heart, leading to serious dysrhythmias. Choices A, B, and C are within normal ranges and do not indicate a need to withhold digoxin.

3. A client is being discharged with a new prescription for metoprolol. Which of the following instructions should the nurse include?

• A. Do not discontinue this medication suddenly.
• B. Take this medication in the evening to decrease the risk of falls.
• C. Monitor your heart rate before taking this medication.
• D. Avoid grapefruit juice while taking this medication.

Correct answer: C

Rationale: The correct instruction for a client prescribed metoprolol is to monitor their heart rate before taking the medication. Metoprolol is a beta-blocker that can cause bradycardia (slow heart rate), so it is essential for clients to check their heart rate before each dose. Choice A is incorrect because abruptly stopping metoprolol can lead to adverse effects, so it should not be discontinued suddenly. Choice B is incorrect because there is no specific recommendation to take metoprolol at night to reduce falls. Choice D is incorrect because grapefruit juice can interact with metoprolol, affecting its absorption, and should be avoided.

4. A nurse is providing dietary teaching to a client with irritable bowel syndrome. Which of the following recommendations should the nurse include?

• A. Consume foods high in bran fiber.
• B. Increase intake of milk products.
• C. Sweeten foods with fructose corn syrup.
• D. Increase intake of foods high in gluten.

Correct answer: A

Rationale: The correct answer is A: Consume foods high in bran fiber. Bran fiber helps alleviate symptoms of irritable bowel syndrome by promoting regular bowel movements. Choice B is incorrect as increasing intake of milk products may exacerbate symptoms in some individuals with irritable bowel syndrome who are lactose intolerant. Choice C is incorrect as fructose corn syrup may worsen symptoms due to its high fructose content, which can be poorly absorbed in some individuals with irritable bowel syndrome. Choice D is incorrect as increasing foods high in gluten may be problematic for individuals with irritable bowel syndrome who have gluten sensitivity or celiac disease.

5. Which electrolyte imbalance is a common concern in patients receiving loop diuretics?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: C

Rationale: The correct answer is Hypokalemia (Choice C). Loop diuretics can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is a common concern with loop diuretic therapy and necessitates regular monitoring. Hyperkalemia (Choice A) is not typically associated with loop diuretics but with conditions like renal failure. Hyponatremia (Choice B) is more common with thiazide diuretics. Hypercalcemia (Choice D) is not a typical concern with loop diuretic use.
