A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

Correct Answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

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.

Correct Answer: B

Rationale: The correct first action when a client receiving a blood transfusion develops a fever is to stop the transfusion and notify the healthcare provider. This is crucial to prevent further reactions and ensure prompt intervention. Administering an antipyretic (Choice A) may mask symptoms and delay appropriate treatment. Slowing the rate of the transfusion (Choice C) might not address the underlying cause of the fever. Continuing the transfusion and reassessing in 15 minutes (Choice D) could worsen the client's condition if there is a severe reaction occurring.

Correct Answer: B

Rationale: The correct answer is B: Decreased fatigue and improved energy levels. Levothyroxine is a medication used to treat hypothyroidism by providing the body with the thyroid hormone it lacks. Therefore, a positive response to the medication would manifest as decreased fatigue and improved energy levels due to the correction of the thyroid hormone imbalance. Choices A, C, and D are incorrect because improved tolerance to cold, reduced anxiety, and increased sensitivity to heat are not direct indicators of the effectiveness of levothyroxine in managing hypothyroidism.

Correct Answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical condition requiring immediate intervention to improve oxygenation. Hypoxemia can lead to tissue hypoxia and further complications. A productive cough with yellow sputum is common in pneumonia but may not require immediate intervention unless it worsens or is associated with other concerning symptoms. A respiratory rate of 20 breaths per minute is within the normal range, indicating adequate ventilation. A heart rate of 90 beats per minute is also within a normal range and may not require immediate intervention unless it is accompanied by other abnormal findings.
