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500 mg per 8 mL, divide the total dosage required by the amount per vial to find out how many milliliters should be withdrawn.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

Explanation

A. A pH within the normal range, a PaCO2 within the normal range, and an improved PaO2 level suggest effective treatment for an asthma attack, indicating adequate gas exchange and resolution of respiratory distress.

B. A pH of 7.52 and low PaCO2 suggest respiratory alkalosis, which can occur with hyperventilation and may indicate overventilation rather than effective asthma treatment.

C. This result shows elevated PaCO2 and borderline low PaO2, indicating ongoing respiratory acidosis and hypoxia, suggesting the treatment is not yet effective.

D. This ABG result shows low pH, indicating acidosis, and a low bicarbonate level, which may indicate metabolic acidosis rather than effective asthma management.
