a pharmacy technician receives a prescription for a 10-ml vial of insulin that contains 100 units/ml. the patient should take 20 units subcutaneously in the morning and 20 units in the evening which of the following is the days supply the patient will receive?
60 days

Explanation:

Step1: Determine total drops per day

The patient instills 1 drop in each eye twice daily. So per eye: \(1 \text{ drop} \times 2 = 2 \text{ drops}\) per day. For two eyes: \(2 \text{ drops/eye} \times 2 \text{ eyes} = 4 \text{ drops/day}\)

Step2: Determine total drops in 5 - mL bottle

Assume 1 mL has 20 drops (standard conversion for eye drops). So 5 mL has \(5 \text{ mL} \times 20 \text{ drops/mL} = 100 \text{ drops}\)

Step3: Calculate days' supply

Days' supply \(=\frac{\text{Total drops}}{\text{Drops per day}}=\frac{100}{4} = 25\)? Wait, no, wait. Wait, maybe my standard conversion is wrong? Wait, no, wait, let's check again. Wait, maybe 1 mL is 20 drops, so 5 mL is 100 drops. But wait, the options have 15,10,20,25. Wait, maybe I made a mistake. Wait, let's re - calculate. Wait, 1 drop per eye, twice daily. So per day: 2 eyes 1 drop 2 times = 4 drops per day. 5 mL: if 1 mL is 20 drops, 520 = 100 drops. 100 / 4 = 25? But wait, maybe the standard is 1 mL = 20 drops, but maybe the question uses a different conversion? Wait, no, maybe I messed up. Wait, let's check the options. Wait, maybe the correct conversion is 1 mL = 20 drops, but let's recalculate. Wait, 5 mL 20 drops/mL = 100 drops. Daily usage: 2 eyes 1 drop 2 times = 4 drops. 100 / 4 = 25. But the options have 25 as an option. Wait, but maybe I made a mistake. Wait, no, let's check again.

Wait, another way: maybe 1 mL is 10 drops? No, standard is 20 drops per mL for eye drops. Wait, let's see the options. If we take 5 mL, 20 drops per mL, so 100 drops. Daily: 2 eyes 1 drop 2 times = 4 drops. 100 / 4 = 25. So the answer should be 25 days.

Wait, but let's check the first calculation again.

Step 1: Drops per day. Two eyes, 1 drop each, twice a day. So 2 (eyes) 1 (drop per eye per administration) 2 (administrations per day) = 4 drops per day.

Step 2: Total drops in 5 - mL bottle. If 1 mL has 20 drops, then 5 mL has 5 * 20 = 100 drops.

Step 3: Days' supply = Total drops / Drops per day = 100 / 4 = 25 days.

Answer:

25 days (the option with "25 days")
