Nursing Elites

1. Which client is at risk for hypomagnesemia?

• A. Client with a history of heart disease
• B. Client taking magnesium-based antacids
• C. Client with a parathyroid disorder
• D. Client admitted with alcohol abuse

Correct answer: D

Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.

2. A client complaining of chest pain is prescribed an intravenous infusion of nitroglycerin (Nitro-Bid). After the infusion is initiated, the occurrence of which symptom warrants the nurse discontinuing an intravenous infusion of nitroglycerin?

• A. Frontal headache
• B. Orthostatic hypotension
• C. Decrease in intensity of chest pain
• D. Cool clammy skin

Correct answer: D

Rationale: The correct answer is 'Cool clammy skin.' This assessment finding indicates decreased cardiac output that could result from excessive vasodilation. Cool clammy skin is a sign of poor perfusion, suggesting that the blood pressure might be dropping too low. Discontinuing the nitroglycerin infusion is crucial to prevent further complications. Choice A, 'Frontal headache,' is a common side effect of nitroglycerin but not a reason to discontinue the infusion unless severe or persistent. Choice B, 'Orthostatic hypotension,' may occur as a side effect of nitroglycerin but does not necessarily warrant discontinuation unless severe. Choice C, 'Decrease in intensity of chest pain,' is actually an expected therapeutic response to nitroglycerin and indicates improved myocardial perfusion, so it is not a reason to stop the infusion.

3. A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?

• A. 1.0 mEq/L
• B. 1.1 mEq/L
• C. 1.2 mEq/L
• D. 1.3 mEq/L

Correct answer: D

Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.

4. One of the major functions of the kidneys in maintaining normal fluid balance is:

• A. the manufacture of antidiuretic hormone.
• B. the regulation of calcium and phosphate balance.
• C. the regulation of the pH of the extracellular fluid.
• D. the control of aldosterone levels.

Correct answer: C

Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

5. A mother who has never breastfed a child before is having trouble getting the baby to latch on to the breast. The baby has lost 3% of its birth weight within the first 2 days of life. The best statement is:

• A. The baby will eventually take to the breast.
• B. I can prepare a bottle if you want to try that.
• C. A small amount of weight loss in the first few days is normal.
• D. I can arrange for the charge nurse to come and talk to you about breastfeeding.

Correct answer: C

Rationale: The correct answer is 'A small amount of weight loss in the first few days is normal.' It is important to reassure the mother that a small amount of weight loss, such as 5-10% of birth weight, in the first few days of life is considered normal for newborns. This reassurance helps alleviate the mother's concerns. Option A is incorrect because it does not address the concern about weight loss; it focuses more on the baby eventually latching on. Option B is not recommended as the first solution for breastfeeding issues, as introducing a bottle early on may lead to nipple confusion. Option D involves escalating the situation to the charge nurse when it can be addressed by providing appropriate information and support directly, making it less necessary in this scenario where reassurance and education are key.
