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 ["B","D","E"]

Explanation

Choice A reason:

Suctioning the patient on a regular schedule is not recommended as it can increase the risk of infection and trauma to the airway. Suctioning should be done as needed based on clinical assessment.

Choice B reason:

Adherence to proper hand hygiene is a fundamental practice in preventing infections, including ventilator-associated pneumonia. Hand hygiene helps prevent the transmission of pathogens.

Choice C reason:

Administering antiulcer medication is important for preventing stress ulcers but is not directly related to preventing ventilator-associated pneumonia.

Choice D reason:

Providing oral care per protocol is essential in reducing the risk of ventilator-associated pneumonia. Oral care helps decrease the bacterial load in the oropharynx and prevent aspiration of contaminated secretions.

Choice E reason:

Elevating the head of the bed to 30-45 degrees helps prevent aspiration of gastric contents and is a key practice in preventing ventilator-associated pneumonia.

A. Provide small doses of opioid analgesia B. Maintain pCO2 of 35-45 C. Administer an anti-anxiety agent D. Monitor blood pressure every four hours

Correct Answer is B

Explanation

Choice A reason:

Providing small doses of opioid analgesia is important for pain management, but it is not the highest priority in a patient with a closed head injury on mechanical ventilation. Pain control should be balanced with the need to monitor neurological status.

Choice B reason:

Maintaining pCO2 of 35-45 is critical for patients with a closed head injury on mechanical ventilation. Proper pCO2 levels help manage intracranial pressure (ICP) and prevent secondary brain injury. Hyperventilation to lower pCO2 can reduce ICP but must be carefully controlled to avoid cerebral ischemia.

Choice C reason:

Administering an anti-anxiety agent can help manage agitation and anxiety, but it is not the highest priority. Sedation must be used cautiously in head injury patients to avoid masking changes in neurological status.

Choice D reason:

Monitoring blood pressure every four hours is necessary for overall patient care, but continuous monitoring and immediate interventions are more critical in managing intracranial pressure and preventing secondary brain injury.
