Answer: 110.2 lbs

Explanation: First, let's determine how many kg the patient masses. Since the dose is 3.000 mg/kg we can convert that to 0.003000 g/kg. So

0.1500 g / 0.003000 g/kg = 50 kg.

So we know the patient has a weight of 50 kg. Now we simply multiply by 2.20462 to get lbs. So

50 kg * 2.20462 lbs/kg = 110.231 lbs

Rounding to 1 decimal place gives 110.2 lbs

Answer:

The patient’s weight is 121.4011 pounds.

Step-by-step explanation:

Amount of medication given as dosage = 3.000 mg/kg of body weight

Amount of medication given = 0.1651 g = 165.1 mg

Let the weight of the person be x

When 3.000 mg of medication given to person with weight 'x' is equal to 165.1 mg.


3.000 mg* x=165.1 mg


x=(165.2 mg)/(3.000 mg)=55.067 kg

1 kg = 2.20462 pounds

55.067 kg =
55.067 kg* 2.20462 pounds=121.4011 pounds

The patient’s weight is 121.4011 pounds.
