PTCB Guide to Prescriptions and Order Entry.

Prescriptions as a Topic on the PTCB Exam.

Prescriptions are a foundational topic of the pharmacy technician exam. Pharmacy technicians are required to have a very strong understanding of prescriptions and order entry-fill process.

On the PTCB exam, prescriptions and order entry are heavily tested because they reflect core daily pharmacy technician responsibilities.

Exam questions typically focus on the following three factors:

• Accuracy
• Compliance with FDA regulations
• Patient safety

At a foundational level, technicians are required to learn all legal elements of a valid prescription.

This mandatory information includes patient name and address, date of prescription, drug name, strength, dosage form, quantity, directions for use (Sig), prescriber name and signature, and (for controlled substances) DEA number. Though most prescriptions are written by physicians, they may also be written by other healthcare professionals (depending on the US state you reside in), including:

• Dentists
• Veterinarians
• Physician assistants
• Certified nurse practitioners

Though all these healthcare professionals can write prescriptions, there are constraints on what medicines they are licensed to prescribe.

Technicians are also required to understand the difference between new prescriptions, refills, transfers, and partial fills, especially for controlled substances. You can expect exam questions on when a prescription expires (non-controlled vs. controlled), what information must be documented during a transfer, and when a new prescription is required.

Order entry accuracy is another major focus. Examinable topics include:

• Interpreting and translating Sig codes (e.g. “1 tab po bid prn”)
• Identifying look-alike/sound-alike drugs
• Entering correct NDC numbers
• Calculating days’ supply and quantity to dispense
• Selecting correct dosage form and strength
• Detecting errors before processing

Technicians should also understand labeling requirements. The Food and Drug Administration requires prescription labels to include key elements such as pharmacy name and address, prescription number, date filled, patient name, prescriber name, directions, and cautionary statements.

Auxiliary labels and medication guides may also be tested.

What details are required to appear on a prescription?

All hard copies of prescriptions must include the following details:

• Name, address, and contact details of the prescriber
• Patient details: name, phone number and date of birth
• Date the prescription was written
• Inscription – name, dosage form, strength, route of administration, and quantity of medicine
• Signa – directions of use
• Subscription – details to the pharmacist on whether refills are permitted, or whether a generic drug can be used in lieu of a trade name. If these details are not needed, DAW – or ‘dispense as written’ should be noted
• Drug Enforcement Administration (DEA) number of the prescriber
• Signature of the physician

Controlled drug prescriptions must include the following additional details:

• Prescriber address
• Prescriber’s DEA number
• Patient address

How to Process a Prescription Safely and Accurately.

For the PTCB exam, pharmacy technicians are required to understand medication order entry and fill process in considerable detail. You will typically be asked scenario-based questions (see below for examples) and asked to identify the source of error.

To correctly process a prescription, pharmacy technicians must forensically analyse the document for all possible sources of error. A systematic approach is recommended.

Pharmacy technicians should identify the following:

• Ensure that the prescription is valid by reviewing date, name, medication, and what quantity of medicine has been prescribed.
• Verify that the name stated on the prescription matches the name given by the patient. For additional authentication, some pharmacies may ask for photo identification.
• Date of birth should be recorded. This is necessary for insurance purposes as well as to distinguish between patients who may share the same name.
• Phone number should be recorded. Patients may need to be contacted regarding their treatment.
• Address should be recorded. This has two functions: first, to ensure that the pharmacy’s patient database is up to date. Second, an address is needed for controlled substances (II through to V) according to the Controlled Substances Act.
• Discuss patient allergies. Discuss with the patient whether they have any allergies. There are two reasons for this – first, to prevent an allergic reaction and second, to prevent any allergies manifesting from any future prescription.
• Record insurance details. Insurance details must be collected to ensure that patients do not pay the full price of the medicine. They are recorded purely for billing purposes.

How to Enter Prescription Details.

Entering prescription details accurately is a fundamental responsibility of a pharmacy technician, as even small errors can affect patient safety and medication efficacy.

This process involves carefully translating the prescriber’s instructions into the pharmacy’s computer system while ensuring compliance with federal and state regulations. From verifying patient and prescriber information to recording drug name, strength, dosage, quantity, directions, and refill information – every element must be checked for accuracy.

Additionally, controlled substances require special attention to DEA requirements, refill limits, and documentation. Below, we review all details that technicians should cover (though we cover Controlled Substances in a separate guide):

• Patient identification. When searching for a patient in the pharmacy’s database, it’s important to first enter the patient’s surname, then the first letter of their first name. A list of names then appears on-screen. Technicians should choose the correct name, and verify that name with the patient’s date of birth.
• Verify insurance details. For example, this is done when the patient presents their new insurance card.
• Prescriber identification. Like when searching for patients in the database, the same process should be followed to identify the prescriber. An insurance audit may be performed, or an oversight on behalf of the pharmacist, if the incorrect provider is listed.
• Drug to be dispensed. This can be achieved by entering the drug name or entering the National Drug Care (NDC) number, which is an 11-digit number with the following sequence: 28754-2500-45. The first 5-digits refer to the drug manufacturer; the next 4-digits refer to drug/strength, whilst the last 2-digits refer to packaging size.
• Quantity dispensed. Due to insurance limits, quantities may have to be adjusted. For example, most insurance companies cover quantities up to 30-days-worth of medicine, and not more.
• Directions for use. This is important because if the pharmacy technician incorrectly interprets the prescription, and the pharmacist also misses the mistake, the patient may be prescribed a harmful dose of the medicine.
• Daily supply. If the quantity of drug is specified as 30 tablets and the directions for use state BID (twice daily), the daily dose is 2 tablets per day.
• Refills. Number of refills must be stated. For example: controlled drugs (III through to V) are permitted to have up to 5 refills with the prescription valid for 6-months only. Controlled drugs II are not permitted to have refills. Non-controlled drugs may have up to 11 refills, with the prescription valid for 1-year from the date it was written.
• Expiration date. Pharmacy technicians must enter a valid expiration date from the stock bottle. An incorrectly entered expiry date could result in a patient taking expired medicines. A practical example of this is tetracycline antibacterial drugs. Taking expired tetracyclines can cause Fanconi syndrome.
• Patient insurance. The final step where the patient’s insurance is processed to ensure that the medicine can be dispensed through the pharmacy.

PTCB Exam-Style Prescription Questions.

Below you can find five sample PTCB exam questions on the topic of prescriptions.

These five questions reflect the type of questions that get tested about order entry and fill process on the exam – both the style and difficulty. As always, have a go at the questions yourself before comparing your answers with the explanations (in the section below).

Question 1.

A pharmacy technician is entering a new prescription for Levothyroxine. Which of the following is not required for a valid prescription?

a. Patient name and address

b. Prescriber name and signature

c. Patient insurance copay amount

d. Drug name, strength, and directions

Question 2.

A prescription reads: “Simvastatin 20 mg, 1 tab po qhs.” Which of the following is the correct way to enter the directions in the pharmacy system?

a. Take 1 tablet by mouth every morning

b. Take 1 tablet by mouth at bedtime

c. Take 20 tablets once daily

d. Take 1 tablet sublingually at night

Question 3.

A new prescription for esomeprazole does not list the quantity. What should the pharmacy technician do?

a. Enter a default quantity based on typical therapy

b. Contact the prescriber to clarify before entering the prescription

c. Leave the field blank and dispense immediately

d. Estimate the quantity based on previous patient prescriptions

Question 4.

A prescription for atorvastatin allows three refills over 12 months. How should this information be entered into the system?

a. Enter the total number of refills and expiration date of the prescription

b. Leave the refills blank and let the pharmacist decide

a. Enter the prescription without the signature and note it in the system

b. Contact the prescriber for clarification before entering the prescription

c. Enter the prescription and allow the pharmacist to sign

d. Replace the signature with the technician’s initials

Answer Explanations.

Answer to Question 1 – c. Patient insurance copay amount

Insurance information is entered separately for billing purposes but is not a required element of the prescription itself. Required prescription details include patient info, prescriber info, drug name, strength, dosage form, directions, quantity, and refills (if applicable).

Answer to Question 2 – b. Take one tablet every night

“po” = by mouth; “qhs” = every night at bedtime. Accurate entry ensures the patient receives correct instructions and supports proper labeling.

Answer to Question 3 – b. Contact the prescriber to clarify before entering the prescription

Pharmacy technicians must verify missing or unclear information with the prescriber before entering it into the system. Accuracy and completeness are critical to prevent medication errors.

Answer to Question 4 – a. Enter the total number of refills and expiration date of the prescription

Technicians must record exact refill limits and prescription expiration date as written to ensure compliance and proper dispensing tracking.

Answer to Question 5 – b. Contact the prescriber for clarification before entering the prescription

A prescriber’s signature is a required element.

Technicians must verify missing information with the prescriber before entering the prescription. Entering incomplete or altered information violates federal and state regulations.
