Providing oral care per protocol.

Elevating the head of the bed.

Answer and Explanation

Correct Answer : B,D,E

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.

Correct Answer is C

Explanation

Choice A reason:

A decrease in specific gravity is not the primary therapeutic outcome of desmopressin in the treatment of diabetes insipidus. Desmopressin works by increasing water reabsorption in the kidneys, which leads to a decrease in urine output and an increase in urine concentration, reflected by an increase, not a decrease, in specific gravity.

Choice B reason:

A decrease in the level of consciousness is not an intended therapeutic outcome and would be concerning if observed. Desmopressin aims to control symptoms of diabetes insipidus, not alter the patient’s mental status.

Choice C reason:

A decrease in urine output is the primary therapeutic outcome of desmopressin in a patient with diabetes insipidus. Desmopressin mimics the action of antidiuretic hormone (ADH), leading to increased water reabsorption in the kidneys and reduced urine volume.

Choice D reason:

Desmopressin does not primarily aim to decrease blood pressure. Its main effect is on water reabsorption in the kidneys, thereby reducing urine output. While it can have some impact on blood pressure, this is not its primary therapeutic outcome.

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.
