To evaluate the effectiveness of mannitol, the nurse should monitor:

Sodium level.

Fluid intake.

Heart rate.

Urine output.

Answer and Explanation

The Correct Answer is D

Choice A reason:

Monitoring sodium levels is important when administering mannitol, but it is not the primary indicator of the drug's effectiveness. Mannitol is an osmotic diuretic used to reduce intracranial pressure, and its effectiveness is better assessed by other means.

Choice B reason:

Fluid intake is important to monitor to ensure proper hydration status, but it does not directly indicate the effectiveness of mannitol. The primary focus should be on the patient's output to assess the diuretic effect.

Choice C reason:

Heart rate monitoring is essential for overall patient care but does not directly indicate the effectiveness of mannitol. Changes in heart rate can occur due to various factors and are not specific to mannitol's action.

Choice D reason:

Urine output is the most direct measure of mannitol's effectiveness. As an osmotic diuretic, mannitol promotes diuresis, and increased urine output indicates that the drug is effectively reducing intracranial pressure.

Correct Answer is D

Explanation

Choice A reason:

Encouraging the patient to deep breathe and use an incentive spirometer is important for lung expansion and preventing atelectasis. However, it is not the most immediate action following extubation.

Choice B reason:

Offering the patient medication for sedation is not appropriate immediately following extubation, as it could depress respiratory function and interfere with the patient's ability to clear secretions and maintain an open airway.

Choice C reason:

Assessing the patient's ability to speak is important to ensure that the vocal cords were not damaged during the intubation process. However, this is secondary to ensuring that the patient is breathing effectively and maintaining adequate oxygenation.

Choice D reason:

Assessing vital signs and effort of breathing is the most immediate and important action following extubation. Monitoring the patient’s respiratory status ensures that they are maintaining a patent airway, breathing effectively, and not experiencing respiratory distress or failure.

Correct Answer is ["83"]

Explanation

To calculate the infusion rate, divide the total volume of fluid to be infused by the total time over which the infusion should occur.

$\frac{330 \text{ mL}}{4 \text{ hours}} = 82.5 \text{ mL/hr}$

Rounding to the nearest whole number, the nurse should set the pump to deliver 83 mL/hr.
