question 2 (1 point)
you receive an order for gentamicin, the order is for 5 mg/kg in two divided doses. the patient weighs 198 lbs. calculate how many mg the patient will receive in one dose?
990 mg
225 mg
450 mg
90 mg

Explanation:

Step1: Calculate drops per day

The patient instills 2 gtts (drops) every 8 hours. There are 24 hours in a day. So the number of administrations per day is $\frac{24}{8}=3$. The number of drops per day is $2\times3 = 6$ drops.

Step2: Calculate total drops in 7 days

If there are 6 drops per day, for 7 days, the total number of drops is $6\times7=42$ drops.

Step1: Convert pounds to kilograms

We know that 1 kg = 2.2 lbs. The patient weighs 198 lbs. So the weight in kg is $\frac{198}{2.2}=90$ kg.

Step2: Calculate total daily dose

The order is 5 mg/kg. For a 90 - kg patient, the total daily dose is $5\times90 = 450$ mg.

Step3: Calculate single - dose amount

The total daily dose is divided into two doses. So the amount per dose is $\frac{450}{2}=225$ mg.

Answer:

42 gtts
