The nurse is educating on the placement of a ventriculostomy (intraventricular catheter) to the patient diagnosed with a brain injury and their family. The nurse states, "The ventriculostomy is placed:

after the client has an electroencephalogram (EEG)."

due to having minimal risk for infection."

by threading it through the femoral artery to the brain."

to monitor intracranial pressure (ICP) and drain the cerebral spinal fluid."

Answer and Explanation

The Correct Answer is D

A. EEG is a monitoring tool for brain activity, but it is not a prerequisite for ventriculostomy placement.

B. While the procedure is carefully managed to reduce infection risk, ventriculostomy does have an infection risk due to its invasive nature.

C. Ventriculostomy is not inserted via the femoral artery; it is placed directly in the brain’s ventricles.

D. A ventriculostomy is used to monitor ICP and allows for the drainage of cerebrospinal fluid, which helps in managing elevated ICP in patients with brain injuries.

Correct Answer is ["16"]

Explanation

To calculate the dosage of Vancomycin, first convert the patient's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The patient weighs 110 lbs, which is equivalent to 50 kg (110 lbs / 2.2). Next, multiply the patient's weight in kilograms by the prescribed dosage of 20 mg/kg, resulting in a total dosage of 1000 mg (50 kg * 20 mg/kg). Since the vials contain 500 mg per 8 mL, divide the total dosage required by the amount per vial to find out how many milliliters should be withdrawn. This results in 16 mL (1000 mg / (500 mg/8 mL)).

A. Nitroprusside B. Furosemide C. 3% Normal Saline D. Norepinephrine

Correct Answer is C

Explanation

A. Nitroprusside is a vasodilator and is not used for managing ICP; it can increase intracranial pressure if not carefully monitored.

B. Furosemide is a diuretic but is less effective for ICP reduction compared to hypertonic saline or mannitol.

C. Hypertonic saline (3% Normal Saline) is used to reduce intracranial pressure by drawing fluid out of the brain tissue and into the bloodstream, which can help prevent cerebral edema.

D. Norepinephrine is a vasopressor and is not used specifically to manage intracranial pressure.
