Final answer:
To fulfill a prescription of 1 gm of Tylenol, you would give three 5 gr capsules to the patient as needed for pain every 6 hours.
Step-by-step explanation:
To determine how many capsules of Tylenol you should give based on the doctor's order, we first need to convert the order from grams to grains since the supply is in grains. We know that 1 gram (gm) is equal to approximately 15 grains (gr). So, for 1 gm, we have:
1 gm × 15 gr/gm = 15 gr
The doctor has ordered 1 gm, and since we have 5 gr capsules, we need to divide the total grains prescribed by the grains per capsule:
15 gr ÷ 5 gr/capsule = 3 capsules
Therefore, you will give three 5 gr capsules to the patient as needed for pain every 6 hours.
