Explanation: The lot number, identified as 'LOT F789GHI', is the unique code used to track a specific manufacturing batch. The NDC number identifies the manufacturer, product, and package size; '500' is the strength; and '12/2026' is the expiration date.

Question 3

A patient reports a severe adverse reaction to a recently filled prescription. To help the manufacturer investigate the issue, which piece of information from the dispensed medication is most important to provide?

  1. The dispensing date.
  2. The lot number. (correct answer)
  3. The prescription number.
  4. The quantity dispensed.
Explanation: The lot number allows the manufacturer to trace the specific batch of medication the patient received. This is crucial for investigating potential quality control issues, such as contamination or incorrect formulation, that might be limited to that single batch.

Question 4

A pharmacy technician is conducting an inventory of controlled substances. They notice two bottles of the same medication with different expiration dates. This difference is most likely associated with the medications having different:

  1. DEA schedules.
  2. NDC numbers.
  3. lot numbers. (correct answer)
  4. therapeutic indications.
Explanation: Medications are produced in batches, each identified by a unique lot number. Each batch will also have its own expiration date assigned during manufacturing. Therefore, different expiration dates on identical products indicate they came from different manufacturing lots.

Question 5

For which of the following routine prescriptions would a pharmacy technician least likely be required by standard pharmacy procedures to document the manufacturer's lot number at the point of dispensing?

  1. Influenza vaccine
  2. Lisinopril 10 mg tablet (correct answer)
  3. A compounded sterile vancomycin IV bag
  4. An isotretinoin capsule under the iPLEDGE REMS program
Explanation: While good practice, lot number tracking is not universally required for routine dispensing of common, non-biologic oral medications like lisinopril. In contrast, it is a strict requirement for vaccines (for tracking adverse events), compounded sterile products (for quality control), and many REMS drugs (as part of the safety protocol).

Question 6

A pharmacy receives a tote of medications from its wholesaler. The packing slip lists the NDC, quantity, and lot number for each item. Why should a technician verify the lot numbers on the physical products against the packing slip?

  1. To ensure the correct drug strength was sent.
  2. To confirm the shipment complies with DSCSA track-and-trace requirements. (correct answer)
  3. To calculate the total cost of the order accurately.
  4. To check if the medications are hazardous substances.
Explanation: Verifying the lot number, along with other data points, is a crucial step in the receiving process under the Drug Supply Chain Security Act (DSCSA). It confirms that the physical product received matches the electronic transaction data, which helps ensure the product is legitimate and not counterfeit or suspect.

Question 7

If a medication is repackaged from a bulk stock bottle into unit-dose packaging, what information must be included on the new unit-dose label?

  1. The original manufacturer's lot number. (correct answer)
  2. The wholesale acquisition cost (WAC).
  3. The DEA number of the supervising pharmacist.
  4. The original prescription number from the bulk bottle.
Explanation: To maintain traceability, the original manufacturer's lot number must be included on the label of any repackaged medication. This ensures that if the original bulk product is recalled, all unit doses created from that batch can be identified and removed from inventory.

Question 8

The lot number on a medication package is assigned by the:

  1. Food and Drug Administration (FDA).
  2. Drug Enforcement Administration (DEA).
  3. dispensing pharmacy.
  4. manufacturer. (correct answer)
Explanation: The lot number is an internal control number assigned by the drug manufacturer during the production process to identify a specific batch of medication. Regulatory bodies like the FDA and DEA do not assign lot numbers, nor does the dispensing pharmacy.

Question 9

When preparing a high-alert medication such as a chemotherapy agent, the lot numbers of the drug and diluent are recorded in the patient's electronic health record (EHR) and on the compounding worksheet. This practice primarily supports:
