*Please show your work!*

A patient weighs 165 pounds. He must receive medication in the amount of 40 mg/kg/day. The medication, which is available in capsules of 150 mg, should be taken in 4 equal doses each day.


Calculate the total number of milligrams the patient must receive each day.



Calculate the number of capsules the patient should take in each dose.

Answer 1

1) 2993,6 mg/day

2) 5 equal doses of 150mg each day.

Step-by-step explanation:

1 pound = 0,45 kg

165 pounds = 74,84kg

if the patient has to receive medication in the amount of 40mg/kg/day the equation you have to do is:

40 mg/kg/day x 74.84kg = 2993.6 mg/day = 3g/day approximately

if one capsule has 150mg and it should be taken in 4 equal doses each day you have to do this calculation:

2993.6 mg / 150 mg = 19,957 capsules, you can use the number 20 to be more exactly.

By last, you have to divide the 20 capsules each day in 4 equal doses so.

20 / 4 = 5

Answer 2

a) 3000 mg

b) 5 capsules

Step-by-step explanation:

Given that:

The patient weighs 165 pounds ≈ 75 kg,

The amount of medication required by the patient = 40 mg/kg/day,

The capsules are in 150 mg and the patient should take 4 equal doses per day.

a) The total number of milligrams per day = Weight of the patient × amount of daily medication required by the patient.

Therefore, The total number of milligrams per day = 75 kg × 40 mg/kg/day = 3000 mg per day.

The patient requires 3000 mg per day.

b) Since the patient requires 3000 mg per day and it must be taken in 4 equal doses:

The number of milligram taken per dose = 3000 mg / 4 = 750 mg per dose.

since each capsule is 150 mg, the number of capsule taken per dose = 750 mg / 150 mg = 5 capsules
