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.
