1) A nurse is administering medication to a patient based

on their body weight. The medication dosage is 0.1 mg/kg.

If the patient weighs 70 kg, how many milligrams of

medication should be administered? Answer: 7 mg.

Rationale: Multiply the patient's weight (70 kg) by the

medication dosage (0.1 mg/kg) to get the dosage in

milligrams.

2) The hospital requires a nurse-to-patient ratio of 1:5. If

there are 25 patients on the floor, how many nurses should

be present? Answer: 5 nurses. Rationale: Divide the

number of patients by the desired nurse-to-patient ratio to

determine the number of nurses needed.

3) A nurse needs to calculate the flow rate of medication

for an intravenous infusion. The infusion pump delivers 60

mL/hour. If the medication order states to administer 120

mg over 4 hours, what should the flow rate be? Answer: 15

mL/hour. Rationale: Divide the total volume (120 mL) by

the total time (4 hours) to determine the flow rate.
