A nurse is preparing to administer fluconazole 42 mg PO to an infant. The nurse should recognize that this is equivalent to how many g? (Round the answer to the nearest thousandth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.042"]

To convert milligrams (mg) to grams (g), one must remember that 1 gram is equivalent to 1000 milligrams. Therefore, to find the equivalent in grams for 42 mg, the amount in milligrams should be divided by 1000. Doing the math, 42 mg divided by 1000 gives 0.042 grams. When rounding this to the nearest thousandth, it remains 0.042, as the fourth decimal place is not significant enough to round up the third decimal place. Hence, 42 mg is equivalent to 0.042 g.

Correct Answer is ["250"]

Explanation

To calculate the infusion rate for an IV pump, you would divide the total volume of the IV fluid to be infused by the number of hours over which the infusion is to run. In this case, 500 mL of dextrose 5% in 0.9% sodium chloride is to be infused over 2 hours. Therefore, the calculation would be 500 mL divided by 2 hours, which equals 250 mL per hour. So, the nurse should set the IV pump to deliver 250 mL/hr.

Correct Answer is ["2"]

Explanation

To calculate the dosage of haloperidol for the child, first determine the total daily dose by multiplying the child's weight by the prescribed amount per kilogram. For a child weighing 40 kg, this would be 0.15 mg/kg/day * 40 kg, which equals 6 mg/day. Since the medication is to be administered in divided doses every 8 hours, divide the total daily dose by the number of doses per day. There are 24 hours in a day, so with doses every 8 hours, that's 3 doses per day. Therefore, 6 mg/day divided by 3 doses per day equals 2 mg per dose.
