A physician prescribes Vancomycin 20 mg/kg intravenous (IV). The patient weighs 110 lbs. The medication is available in vials which contain 500 mg per 8 mL. What should the nurse withdraw from the vial? (round to the nearest whole number)

Answer and Explanation

The Correct Answer is ["16"]

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500 mg per 8 mL, divide the total dosage required by the amount per vial to find out how many milliliters should be withdrawn.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)).

Correct Answer is C

Explanation

A. This is a correct statement, as using multiple drugs helps to reduce the likelihood of resistance and enhances viral suppression.

B. This is accurate; if resistance develops, alternative medications or combinations can be considered.

C. This statement indicates a misunderstanding. Antiretroviral medications do not kill the virus; they suppress its replication. Lifelong adherence to antiretroviral therapy is necessary to manage HIV and prevent viral rebound.

D. Correct, as an effective regimen should lead to an increase in CD4 count and improved immune function.

A. Use the head tilt chin lift method to maintain the airway B. Control any external bleeding C. Do not move the victim from the accident D. Stabilize the cervical spine until help arrives

Correct Answer is D

Explanation

A. The head tilt chin lift method should be avoided due to the risk of aggravating a spinal injury; the jaw-thrust maneuver is safer if airway management is necessary.

B. While controlling bleeding is important, cervical spine stabilization takes priority in trauma with suspected spinal injury.

C. Not moving the victim is appropriate, but stabilizing the cervical spine provides active support to avoid further injury.

D. Stabilizing the cervical spine is crucial to prevent potential spinal cord damage in an unconscious trauma victim, particularly in a motor vehicle accident. This action helps prevent exacerbation of any spinal injury.
