A physician prescribes Vancomycin 20 mg/kg IV. The client weighs 110 lbs. The medication is available in vials which contain 500 mg per 8 mL. What should the nurse withdraw from the vial?
The Correct Answer is ["16"]
To calculate the volume to be withdrawn from the vial, we need to follow these steps:
- Convert the client's weight from pounds to kilograms:
- 110 lbs * (1 kg / 2.2 lbs) = 50 kg
- Calculate the total dose of Vancomycin based on the prescribed dosage:
- 20 mg/kg * 50 kg = 1000 mg
- Calculate the volume to be withdrawn from the vial:
- 1000 mg * (8 mL / 500 mg) = 16 mL

Explanation
A. Stage IV pancreatic cancer often leads to bile duct obstruction, causing decreased bile flow into the intestines. This results in clay-colored stools due to the absence of bile pigments.
B. Hematuria, or blood in the urine, is not a common symptom of pancreatic cancer, even in advanced stages. It is more associated with conditions affecting the urinary system.
C. Jaundice causes dark, concentrated urine rather than pale, dilute urine due to the accumulation of bilirubin in the bloodstream, which is excreted through the kidneys.
