Final answer:
To fulfill the Nembutal prescription of 0.1 grams, convert the amount to milligrams (100 mg) and then divide by the capsule strength (50 mg) to determine that two capsules need to be administered.
Step-by-step explanation:
The question involves calculating the number of Nembutal capsules to administer to a patient for sleep. The prescription is for 0.1 g of Nembutal to be taken by mouth at bedtime as needed (pro re nata, prn). The medication comes in 50 mg capsules.
First, convert the prescribed amount from grams to milligrams: 0.1 grams is equivalent to 100 milligrams. Now, divide the prescribed dose (100 mg) by the strength of each capsule (50 mg) to determine the number of capsules needed:
100 mg / 50 mg per capsule = 2 capsules.
Therefore, you will give the patient two 50 mg capsules of Nembutal for the desired 0.1 g dose.
