Nursing Elites

1. A patient is admitted to the hospital with a diagnosis of primary hyperparathyroidism. A nurse checking the patient's lab results would expect which of the following changes in laboratory findings?

• A. Elevated serum calcium
• B. Low serum parathyroid hormone (PTH)
• C. Elevated serum vitamin D
• D. Low urine calcium

Correct answer: A

Rationale: In primary hyperparathyroidism, there is excess secretion of parathyroid hormone (PTH) leading to increased resorption of calcium from bones and decreased excretion of calcium by the kidneys. This results in elevated serum calcium levels. Elevated serum calcium is a hallmark characteristic of primary hyperparathyroidism, making it the correct answer. Low serum parathyroid hormone (PTH) (Choice B) is incorrect because primary hyperparathyroidism is associated with elevated PTH levels due to the malfunction of the parathyroid glands. Elevated serum vitamin D (Choice C) is incorrect because primary hyperparathyroidism is not typically associated with elevated vitamin D levels. Low urine calcium (Choice D) is incorrect as primary hyperparathyroidism leads to decreased calcium excretion by the kidneys, resulting in high levels of calcium in the urine.

2. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

3. A 7-year-old child is seen in a clinic, and the pediatrician documents a diagnosis of nighttime (nocturnal) enuresis. What information should the nurse provide to the parents?

• A. Nighttime (nocturnal) enuresis does not respond to treatment.
• B. Nighttime (nocturnal) enuresis is caused by a psychiatric problem.
• C. Nighttime (nocturnal) enuresis requires surgical intervention to improve the problem.
• D. Nighttime (nocturnal) enuresis is usually outgrown without therapeutic intervention.

Correct answer: D

Rationale: Nighttime (nocturnal) enuresis is common in children and is characterized by a child who has never been dry at night for extended periods. Most children eventually outgrow bedwetting without therapeutic intervention. This condition is due to the child being unable to sense a full bladder and not awakening to void, often related to delayed maturation of the central nervous system. It is important for parents to understand that nighttime (nocturnal) enuresis is not caused by a psychiatric problem, does not typically require surgical intervention, and usually resolves on its own over time.

4. A nurse and client are discussing the client's progress toward understanding his behavior under stress. This is typical of which phase in the therapeutic relationship?

• A. Pre-interaction
• B. Orientation
• C. Working
• D. Termination

Correct answer: C

Rationale: The correct answer is the working phase. During this phase, the nurse and client actively work together to explore alternative behaviors and techniques. Discussions in this phase focus on understanding the underlying meaning behind the behavior and implementing strategies for change. Pre-interaction (choice A) refers to the phase before the nurse and client first meet and establish a relationship. The orientation phase (choice B) involves introductions, setting goals, and establishing boundaries. Termination (choice D) is the phase where the therapeutic relationship concludes, and closure is achieved.

5. A home care nurse instructs the mother of a 5-year-old child with lactose intolerance about dietary measures for her child. The nurse should tell the mother that it is necessary to provide which dietary supplement in the child's diet?

• A. Fats
• B. Zinc
• C. Protein
• D. Calcium

Correct answer: D

Rationale: In lactose intolerance, the inability to digest lactose, the sugar in dairy products, can lead to calcium deficiency if dairy products are removed from the diet. Calcium is crucial for bone health and other bodily functions, so alternative calcium sources like fortified non-dairy milks or leafy greens must be included to prevent deficiency. While fats and proteins are important nutrients, they are not typically deficient in lactose intolerance. Zinc, although an essential mineral, is not the primary concern in this case.
