1. A patient's dosage of medication is determined by their weight in
kilograms. If the dosage is 0.1 mg/kg, and the patient weighs 70 kg, how
many milligrams of medication should they receive?
Answer: 7 mg. Rationale: 0.1 mg/kg x 70 kg = 7 mg.
2. A nursing student needs to calculate the total volume of medication to
be administered to a patient over a 24-hour period. If the medication is
to be given at a rate of 5 ml/hour, how many milliliters of medication
should be prepared for the day?
Answer: 120 ml. Rationale: 5 ml/hour x 24 hours = 120 ml.
3. A patient's blood pressure is 140/90 mmHg. Calculate the patient's
mean arterial pressure (MAP) using the formula: MAP = (2/3 * diastolic) +
(1/3 * systolic).
Answer: 106.67 mmHg. Rationale: MAP = (2/3 * 90) + (1/3 * 140) = 106.67
mmHg.
4. A nurse needs to calculate the infusion rate for a medication to be
administered over 5 hours. If the medication is to be given at a rate of 50
mcg/min, how many micrograms per hour should be administered?
Answer: 15,000 mcg/hour. Rationale: 50 mcg/min x 60 min/hour = 3,000
mcg/hour. 3,000 mcg/hour x 5 hours = 15,000 mcg/hour.
5. A patient's body mass index (BMI) is calculated using the formula: BMI =
weight (kg) / height (m^2). If a patient weighs 70 kg and is 1.75 meters
tall, what is their BMI?
Answer: 22.86 kg/m^2. Rationale: 70 kg / (1.75 m)^2 = 22.86 kg/m^2.
6. A nursing student needs to calculate the dosage of a medication to be
administered to a patient based on their body surface area (BSA). If the
patient's BSA is 1.8 m^2 and the dosage is 10 mg/m^2, how manyÂÂ
