Before dispensing a prescription, pharmacy technicians and pharmacists must ensure that it iscomplete, clear, and unambiguousto avoid medication errors.

Medication:Lisinopril

Strength:20 mg (Clear)

Route:PO (by mouth) (Clear)

Directions:Take 1 tab PO q8h (every 8 hours)❌(Needs Clarification)

Quantity:30 tablets (Clear)

Refills:12 (Needs verification but is not the main issue)

Lisinopril is an ACE inhibitorused for hypertension and heart failure.

Standard dosing is once daily (q24h), not every 8 hours (q8h).

A frequency of q8h (three times daily) is unusual and could be a prescribing error.

Pharmacists must verify with the prescriber before dispensing.

(A) Directions for use✅Correct – "q8h" is incorrect for lisinopril and needs clarification.

(B) Medication strength❌Incorrect – "20 mg" is a standard strength for lisinopril.

(C) Route of administration❌Incorrect – "PO" (by mouth) is correct.

(D) Number of refills❌Incorrect – While 12 refills is uncommon for chronic medications, it is not the primary issue.

Analysis of the Prescription:Why the Directions Need Clarification:Analysis of Answer Choices:References for Pharmacy Technicians:

Look-alike/sound-alike (LASA) medications pose asignificant risk of medication errors. To reduce this risk, pharmacies should:

Use both brand and generic nameson labels to clarify drug identity.

Example:"Celexa (Citalopram)" vs. "Celebrex (Celecoxib)."

B. Place the drug next to another look-alike/sound-alike drug on the shelf if they are alphabetical.❌→Incorrect

LASA drugs shouldnotbe stored next to each other.

Example:Hydroxyzine and Hydralazine should be stored separatelyto avoid mix-ups.

C. Review the first five digits of the NDC to confirm the correct product.❌→Incorrect

The first five digits (manufacturer code) only identify the manufacturer, not the specific drug.

Instead, checking theentire NDC (all 10-11 digits) is necessary.

D. Take hazardous drug precautions.❌→Incorrect

LASA errors are a labeling issue, not a hazardous drug issue.

Institute for Safe Medication Practices (ISMP) LASA Guidelines– Recommends usingboth brand and generic names on labels.

FDA & Joint Commission LASA Drug Safety Recommendations– Emphasizes labeling improvements for LASA drugs.

TheM-M-R II (Measles, Mumps, and Rubella) vaccinemust bereconstituted only with the manufacturer-supplied diluentto maintain its efficacy and stability.

The manufacturer-provided diluent contains stabilizing agents that preserve the live attenuated virus.

Using normal saline can alter the pH and degrade the vaccine, making it ineffective.

The vaccine must be discarded if reconstituted incorrectlyand not administered.

A. Administer the vaccine as the diluents are equivalent.❌→Incorrect

Normal saline is NOT equivalent to the manufacturer’s diluentand can compromise the vaccine’s potency.

B. Report the incident to the Drug Enforcement Administration (DEA).❌→Incorrect

Vaccine errors should be reported to the CDC’s Vaccine Adverse Event Reporting System (VAERS), not the DEA(which handles controlled substances, not vaccines).

C. Contact the Environmental Protection Agency (EPA) for guidance.❌→Incorrect

The EPA regulates hazardous waste, not vaccine errors.The CDC or vaccine manufacturer should be contacted for guidance.

CDC Vaccine Storage and Handling Guidelines– States thatvaccines must be reconstituted only with manufacturer-supplied diluents.

FDA Guidelines for M-M-R II Vaccine– Confirms that improper reconstitutionrenders the vaccine ineffective.

Why Is Normal Saline Not an Acceptable Diluent?Why Not the Other Options?Key References:

The CDC emphasizes that handwashing prevents illness primarily because germs (pathogens) are commonly spread when people touch contaminated surfaces, objects, or other people and then touch their eyes, nose, or mouth. Proper handwashing removes these pathogens and interrupts this transmission route. The other options are incorrect: (B) is not a reason recognized by CDC; (C) misstates the mechanism (pathogens on hands don’t “weaken the immune system” directly—transmission to entry sites causes infection); and (D) is false—soap and water are often preferred, and alcohol-based sanitizer does not work against all organisms (e.g., spores like C. difficile and some viruses), whereas handwashing does.

• CDC Hand Hygiene guidance for the public and healthcare settings highlighting touch as a primary transmission pathway and the effectiveness of handwashing.

• PTCB/ExCPT study materials on infection control and hand hygiene principles in pharmacy practice.

• USP <795>/<797> introductory hygiene expectations reinforcing handwashing to reduce contamination risk.

• DEA Form 41 (“Registrants Inventory of Drugs Surrendered”) is the federal form used to document the destruction (disposal) of controlled substances by a registrant.

• Opioid analgesics are controlled substances and therefore require DEA Form 41 for authorized destruction.

• NSAIDs, penicillins, and most monoclonal antibodies are not controlled substances and do not require DEA Form 41 for disposal.

Enteric-coated (EC) tabletsare designed todelay drug release until they reach the intestine, preventing stomach irritation and degradation by gastric acid. The coatingresists stomach acidbut dissolves in thehigher pH environment of the intestines.

Aspirin EC(prevents stomach irritation)

Pantoprazole EC(proton pump inhibitor)

Diclofenac EC(NSAID)

A. Buffered→ Incorrect; buffered formulationsneutralize stomach acidbut do not delay release until the intestines.

C. Controlled release→ Incorrect; controlled-release formulationsgradually release medicationover time but are not specifically designed tobypass the stomach.

D. Buccal→ Incorrect; buccal tablets dissolve in thecheek mucosa, bypassing the digestive system entirely.

Diflucan (Fluconazole) is an antifungal medicationused to treatsystemic and local fungal infections, including:

Candidiasis (oral thrush, vaginal yeast infections)

Cryptococcal meningitis

Fungal infections in immunocompromised patients (HIV/AIDS, chemotherapy patients, etc.)

Fluconazole works byinhibiting fungal ergosterol synthesis, which is essential for fungal cell membrane integrity.

A. Bacterial infections❌→Incorrect

Fluconazole does NOT treat bacterial infections; antibiotics are required instead.

B. Gastroesophageal reflux disease (GERD)❌→Incorrect

Proton pump inhibitors (PPIs) or H2 blockers(e.g., omeprazole, ranitidine) are used for GERD.

C. Altitude sickness❌→Incorrect

Acetazolamide (Diamox) is used for altitude sickness, not fluconazole.

FDA Fluconazole Drug Label– Confirms antifungal indications.

Centers for Disease Control and Prevention (CDC) Guidelines– Lists fluconazole asa treatment for candidiasis and cryptococcal meningitis.

Handling and internal transport of hazardous waste in the workplace require compliance with OSHA standards, including Hazard Communication and HAZWOPER (29 CFR 1910.120) training for personnel involved in hazardous waste operations. While external shipment of hazardous materials involves DOT/EPA rules, within pharmacy and healthcare settings, technicians moving hazardous waste containers to storage must have OSHA-mandated training. DEA pertains to controlled substances, FDA regulates drug approval/labeling, and ISMP is a safety organization but does not mandate training.

Cyanocobalamin (Vitamin B12)is used to treatpernicious anemia, a condition caused byVitamin B12 deficiencydue to the body’s inability to absorb it properly.

Pernicious anemiais an autoimmune disorder where the stomach does not produceintrinsic factor, a protein needed for Vitamin B12 absorption.

Symptoms includefatigue, weakness, neurological issues (numbness, tingling), and megaloblastic anemia.

Cyanocobalamin is given viaIM injection or high-dose oral supplementation.

(A) Pernicious anemia✅Correct – Cyanocobalamin is the primary treatment.

(B) Alcohol withdrawal❌Incorrect – Thiamine (Vitamin B1) is used for alcohol withdrawal, not cyanocobalamin.

(C) Hypothyroidism❌Incorrect – Treated withlevothyroxine (Synthroid), not Vitamin B12.

(D) Narrow-angle glaucoma❌Incorrect – Treated withtimolol, acetazolamide, or surgery, not cyanocobalamin.
