Question

a pharmacy technician is processing a prescription for 60 tablets of a medication. the instructions read, 1 tab po qid. the technician should identify that which of the following is the days supply for this prescription? 30 days 20 days 10 days 15 days question 25 a pharmacy technician receives a prescription for insulin 100 units/ml with instructions to inject 30 units daily for 28 days. how many 3-ml vials should the technician plan to dispense? one two three

Explanation:

First Question (Days' Supply)

Step1: Understand "qid"

"qid" means 4 times a day. So daily dose is 1 tab × 4 = 4 tabs/day.

Step2: Calculate days' supply

Total tablets = 60. Days' supply = $\frac{60}{4}$ = 15? Wait, no, wait: Wait, 1 tab po qid: po is by mouth, qid is 4 times daily. So 1 tab × 4 times = 4 tabs per day. Then 60 tabs ÷ 4 tabs/day = 15 days? Wait, but let's check again. Wait, maybe I made a mistake. Wait, 1 tab qid: 4 times a day, so 4 tabs daily. 60 ÷ 4 = 15. Wait, but the options have 15 days. Wait, but let's re-express:

Wait, the first question: 60 tablets, 1 tab po qid (4 times daily). So daily consumption: 1 * 4 = 4 tablets. Days' supply = total tablets / daily tablets = 60 / 4 = 15 days? Wait, but the options are 30,20,10,15. So 15 days. Wait, but maybe I miscalculated. Wait, no: 1 tab four times a day is 4 tabs per day. 60 divided by 4 is 15. So the answer is 15 days? Wait, but let's check again.

Wait, maybe I misread "qid". Qid is four times a day. So 1 tab × 4 = 4 tabs daily. 60 tabs / 4 tabs per day = 15 days. So the correct option is 15 days.

Step1: Calculate total units needed

Daily units: 30 units, for 28 days. Total units = 30 × 28 = 840 units.

Step2: Calculate units per vial

Insulin is 100 units/mL, vial is 3 mL. So units per vial = 100 units/mL × 3 mL = 300 units per vial.

Step3: Calculate number of vials

Number of vials = $\lceil \frac{840}{300}
ceil$ (ceiling function, since we can't dispense partial vials). 840 ÷ 300 = 2.8. So we need 3 vials? Wait, no: Wait, 300 units per vial. 2 vials would be 600 units, which is less than 840. 3 vials: 900 units, which is enough. Wait, but let's check again.

Wait, total units: 30 units/day × 28 days = 840 units.

Each 3-mL vial has 100 units/mL × 3 mL = 300 units.

Number of vials needed: 840 ÷ 300 = 2.8. Since we can't dispense 0.8 of a vial, we need to round up to 3? Wait, but maybe the options are One, Two, Three, etc. Wait, the problem says "How many 3-mL vials should the technician plan to dispense?"

Wait, 30 units daily for 28 days: 30*28=840 units.

Each vial is 3 mL, 100 units/mL: 3*100=300 units per vial.

840 / 300 = 2.8. So we need 3 vials (since 2 vials would give 600 units, which is not enough for 840 units). So the answer is Three.

Answer:

15 days (the option: 15 days)

Second Question (Insulin Vials)
