PTCE Order Interpretation and Medication Preparation 1 — Questions and Answers
Question 1: A physician orders 250 mg of a medication to be given to a patient. The medication is available in 500 mg tablets. How many tablets should the pharmacy technician dispense?
- 1/2 tablet (Correct answer)
- 1 tablet
- 2 tablets
- 5 tablets
Correct answer: 1/2 tablet
To calculate the amount, divide the ordered dose by the available strength: 250 mg (ordered) / 500 mg (available) = 0.5. Therefore, the pharmacy technician should dispense 1/2 of a tablet.
Question 2: What is the correct interpretation of the following prescription? <br> "Amoxicillin 500 mg, take 1 capsule every 8 hours for 10 days."
- The patient should take 1 capsule once a day for 10 days
- The patient should take 1 capsule every 8 hours for 10 days (Correct answer)
- The patient should take 2 capsules every 8 hours for 10 days
- The patient should take 1 capsule twice a day for 10 days
Correct answer: The patient should take 1 capsule every 8 hours for 10 days
The prescription explicitly states "take 1 capsule every 8 hours for 10 days." This means the patient should take one capsule three times a day (24 hours divided by 8 hours) for the specified duration of ten days.
Question 3: A prescription reads "Lidocaine 5% cream, apply a thin layer to the affected area every 12 hours as needed for pain." How should the technician prepare this medication for the patient?
- Dispense a 5% solution of lidocaine
- Dispense a 5% cream for topical use (Correct answer)
- Dispense a 5% ointment for oral use
- Dispense a 5% patch for transdermal use
Correct answer: Dispense a 5% cream for topical use
The abbreviation "PO" stands for "per os," meaning by mouth or orally, and "once" indicates a single dose. Therefore, the order instructs to dispense a 150 mg oral tablet of Fluconazole to be taken one time only.
Question 4: A prescription is written for Digoxin 0.25 mg daily. The available tablet strength is 0.125 mg. How many tablets should be dispensed to fulfill a 30-day supply?
- 15 tablets
- 30 tablets
- 60 tablets (Correct answer)
- 120 tablets
Correct answer: 60 tablets
The patient needs 0.25 mg daily, and the available tablet strength is 0.125 mg. This means 2 tablets are required per day (0.25 mg / 0.125 mg = 2 tablets/day). For a 30-day supply, the total number of tablets needed is 2 tablets/day * 30 days = 60 tablets.
Question 5: If a prescription reads: <br> "Fluconazole 150 mg PO once" <br> How should the pharmacy technician interpret this order?
- Dispense a 150 mg oral tablet to be taken once (Correct answer)
- Dispense 150 mg oral suspension to be taken daily
- Dispense 150 mg injectable fluconazole to be taken once
- Dispense a 150 mg oral tablet to be taken daily
Correct answer: Dispense a 150 mg oral tablet to be taken once
