A nurse is preparing to administer 1 mg of vitamin K to a newborn. The medication is available in 1 mg/0.5 mL. How much should the nurse administer? (Round to the nearest tenth. Use a leading zero when applicable. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To calculate the volume of vitamin K to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 1 mg / 1 mg/mL
Volume (mL) = 1 mL
However, the medication is available in a 0.5 mL vial containing 1 mg of vitamin K. This means that the entire 0.5 mL vial contains the desired dose of 1 mg.
Therefore, the nurse should administer 0.5 mL of vitamin K.

Correct Answer is ["175.0"]
Explanation
First, convert the infant's weight from grams to kilograms:
3500 g x (1 kg / 1000 g) = 3.5 kg
Next, calculate the cephazolin dose:
Dose = 50 mg/kg x 3.5 kg
Dose = 175 mg
Therefore, the nurse should administer 175.0 mg of cephazolin per dose.
