Nursing Elites

1. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

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

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

2. A preschool-aged boy is admitted to the pediatric unit following successful resuscitation from a near-drowning incident. While providing care to the child, the nurse begins talking with his preadolescent brother who rescued the child from the swimming pool and initiated resuscitation. The nurse notices the older boy becomes withdrawn when asked about what happened. Which action should the nurse take?

• A. Involve the older brother in supporting the child
• B. Ask the older brother how he felt during the incident
• C. Ask the parents for more information about the brother's behavior
• D. Reassure the brother that everything is fine now

Correct answer: B

Rationale: The older brother's withdrawal likely indicates emotional trauma or stress from the near-drowning event. Asking how he felt provides an opportunity for emotional support and allows the child to express feelings that may need addressing. Involving him in supporting the child may be overwhelming and not address his emotional needs directly. Asking the parents for more information may not allow the older brother to express his own feelings. Simply reassuring him that everything is fine now may dismiss his emotional experience without providing a chance for him to process his feelings.

3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

4. The nurse is caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?

• A. Disconnect the client from the ventilator and use a manual resuscitation bag
• B. Perform a quick assessment of the client's condition
• C. Call the respiratory therapist for help
• D. Press the alarm reset button on the ventilator

Correct answer: B

Rationale: The correct answer is to perform a quick assessment of the client's condition when the high-pressure alarm goes off on the ventilator. This assessment is crucial to determine the cause of the alarm and the client's current status. Option A is incorrect because disconnecting the client from the ventilator without assessing the situation can be harmful. Option C is incorrect as the nurse should first assess the client before seeking additional help. Option D is incorrect because resetting the alarm without understanding the underlying issue may lead to potential risks to the client.

5. A client is admitted with a severe burn injury. What is the nurse's priority intervention?

• A. Monitor the client's urine output.
• B. Administer intravenous fluids.
• C. Apply cool, moist compresses to the burn area.
• D. Cover the burn area with a sterile dressing.

Correct answer: B

Rationale: The correct answer is B: Administer intravenous fluids. In a client with severe burn injury, the priority intervention is to administer intravenous fluids to prevent shock. Monitoring urine output (Choice A) is important but not the priority. Applying cool, moist compresses (Choice C) can be beneficial but is not the priority over fluid resuscitation. Covering the burn area with a sterile dressing (Choice D) is important for wound care but is not the immediate priority in managing severe burns.
