while still in the hospital, the doctor writes an order for an antibiotic at 400mg / kg / day. You are nervous now because the nurse was wrong before. Assuming that you weigh 132 lb, determine how many milligrams should you be given. What is the equivalent number of grams? ( Hint: 1000mg = 1 g and mg / kg / day = mg/ kg × day)

Answers

Answer:

Patient will require 23950 mg or 23.95 gm of the antibiotic per day.

Step-by-step explanation:

The doctor has written an antibiotic at 400 mg per Kg body weight per day (400 mg/Kg/day).

Weight of patient is 132 lb.

So we will convert it into kilograms.

Since 1 lb = 0.4536 Kg

Therefore, 132 lb = 132 × 0.4536

                            = 59.875 kg

Weight of the patient is 59.875 kg

Now we can calculate the dose of the antibiotic by this weight of the patient.

∵ 1 Kg patient requires dose of antibiotic = 400 mg

∴ 59.875 Kg patient will require the dose = 400 × 59.875

                                                                     = 23950 mg

We know 1 mg = (1)/(1000) gms

So 23950 mg = (23950)/(1000) gms

                       = 23.95 gm per day

Therefore, patient will require 23950 mg or 23.95 gm of the antibiotic per day.
123 lb * (0.4536 kg/lb) * 300mg/(kg · day) = (123 * 0.4536 * 300) mg/day = 16737.84 mg/day 16737.84 mg/day * 1g/(1000mg) = 16.73784 g/day
