Apidra (insulin glulisine)is arapid-acting insulinthat must bestored between 36°F and 46°F (2°C to 8°C)in the refrigerator. If frozen,it is no longer usableand shouldnever be thawed or dispensed. The best course of action is toreturn it to the distributorto ensure medication integrity and patient safety.

A. Thawed and stored in a refrigerator→ Incorrect;frozen insulin loses its potencyand shouldnot be used.

B. Sent to the prescriber→ Incorrect; the prescriber does not handle medication storage or replacements.

C. Dispensed to a patient→ Incorrect;frozen insulin is ineffectiveand could harm the patient.

Manufacturer Storage Requirements for Apidra (Sanofi-Aventis)

Thevaricella (chickenpox) vaccine(brand nameVarivax) is alive attenuated virus vaccinethat requiresfreezingto maintain stability.

TheCDC and manufacturers (Merck) require that Varicella vaccine be stored in a freezer at:

Temperature range: -50°C to -15°C (-58°F to +5°F)

Acceptable range:-20°C to -10°C (-4°F to 14°F)

Do NOT store in the refrigerator–Refrigeration deactivates the live virus, making the vaccine ineffective.

Store in a stand-alone freezer(not in a refrigerator/freezer combo) to ensure temperature stability.

B. In the refrigerator (2°C to 8°C/36°F to 46°F)❌→Incorrect.

Refrigerationcompromises the vaccine’s potency, leading to inactivation of the live virus.

C. At room temperature (15°C to 30°C/59°F to 86°F)❌→Incorrect.

Room temperature storage causes rapid degradation of the live virus, rendering the vaccine ineffective.

D. In a warmer (30°C to 40°C/86°F to 104°F)❌→Incorrect & Unsafe.

Thisdestroysthe vaccine and makes it completely ineffective.

Centers for Disease Control and Prevention (CDC) Vaccine Storage and Handling Guidelines– States that varicella vaccinesmust be stored in the freezer at -50°C to -15°C (-58°F to +5°F).

Manufacturer (Merck) Guidelines for Varivax– Specifies strict freezer storage requirements.

When a patient is prescribed two medications from the same therapeutic class, the pharmacy's prescription processing system may flag this as"therapeutic duplication."

This alert is meant toprevent potential adverse effectssuch as excessive lowering of blood pressure or heart rate.

A. Prior authorization required→ Not applicable unless the insurance requires special approval before covering the drug.

C. NDC not covered→ Would appear if the specific drug product (based on its National Drug Code) is not covered by insurance, but this scenario relates to duplication, not coverage.

D. Refill too soon→ This applies to refilling a medication before the allowed time frame, but the scenario describes a new prescription.

Repatha (evolocumab) is a PCSK9 inhibitor used for lowering LDL cholesterol. One of its common side effects includes musculoskeletal pain, such as muscle aches and cramps. According to the FDA package insert for Repatha, clinical trials observed arthralgia, myalgia, and back pain as notable adverse events.

In contrast:

Requip (ropinirole) may cause dizziness or nausea.

Restasis (cyclosporine ophthalmic) causes eye irritation.

Restoril (temazepam) is associated with sedation.

Phenobarbital is abarbiturateused forseizure control, sedation, and epilepsy management. It is commercially available in both:

Oral tablet form(commonly used for long-term seizure control).

Injectable solution form(used in hospital settings for status epilepticus and acute seizure episodes).

B. Paroxetine❌→Available only as oral tablets and oral suspension.

C. Pioglitazone❌→Available only as oral tablets (for diabetes management).

D. Pramipexole❌→Available only as oral tablets (for Parkinson’s disease and restless legs syndrome).

The original sig reads:

“i tab PO t.i.d.” which means “take one tablet by mouth three times a day”.

If the label instructs twice daily (b.i.d.) instead of t.i.d., it is a dosage frequency error, leading to under-dosing.

According to Mosby’s Pharmacy Technician: Principles and Practice:

“A transcription error in the frequency of administration can result in subtherapeutic dosing or treatment failure. Accuracy in translating sig codes is essential.”

Other options:

Route (PO) is correct.

Days supply is still 7 days.

Dosage form (tablet) is unchanged.

A. Highlights the similarities in drug names.→ Incorrect. Tall Man lettering highlightsdifferences, not similarities, toprevent confusion.

B. Ensures all trade names will be capitalized.→ Incorrect. Tall Man lettering applies toboth brand and generic names, but it is used specifically for drugs with look-alike names.

D. Keeps the pharmacy inventory in alphabetic order.→ Incorrect. Inventory order is based onstandard drug names, not Tall Man lettering.

When adrug recalloccurs due totemperature excursions(exposure to temperatures outside the manufacturer’s recommended range during transport or storage), the pharmacy mustimmediately remove all affected productfrom its inventory to prevent dispensing compromised medication.

Remove the Affected Product:Quarantine the recalled drug to ensure it is not dispensed.

Verify the Recall Details:Confirm the lot number, expiration date, and reason for the recall using FDA or manufacturer recall notices.

Document the Recall Action:Log details in the pharmacy's recall records for compliance.

Follow Manufacturer or FDA Instructions:Some recalls require returning the product, while others require disposal according to hazardous waste guidelines.

Notify Patients and Providers (If Necessary):If the medication has already been dispensed, further action may be needed depending on recall severity.

B. Contact patients who received a therapeutically equivalent product.→ Incorrect. The recall applies to thespecificaffected lot, not all similar medications. Pharmacists would first verify which patients received the recalled drugbefore contacting them.

C. Switch patients from the oral solution to oral capsules.→ Incorrect. The recall does not automatically require a formulation change. The pharmacy must verify availability of unaffected stock or alternative treatments before making substitutions.

D. Contact all prescribers who recently prescribed the product.→ Incorrect. While prescribersmayneed notification if the recall affects patient treatment, thefirst stepis ensuring the recalled product is removed from stock to prevent further dispensing.

Under the federal Controlled Substances Act, schedules are codified in Title 21 of the Code of Federal Regulations (CFR), Part 1308. Schedule II substances are those with a high potential for abuse, with use potentially leading to severe psychological or physical dependence, and which have accepted medical uses in the United States. Methadone is explicitly listed as a Schedule II opioid analgesic. By contrast, metoprolol (a beta-blocker), metformin (a biguanide antidiabetic), and methotrexate (an antimetabolite) are not controlled substances under federal scheduling.

Alot numberis a unique identifier assigned to a specific batch of a medication during manufacturing.

TheNational Drug Code (NDC)andserial numberare different from the lot number.

On medication stock bottles, the lot number is often preceded by"(10)", which is present in this case:

(10)ABC123→This represents the lot number.

B. 55555444422→ This appears to be aGTIN (Global Trade Item Number), which identifies the product but is not the lot number.

C. 051526→ This could represent a manufacturer’s internal code or part of the packaging details, but not the lot number.

D. 11262026→ This follows the(21) identifier, which represents theexpiration date (November 26, 2026).
