References for Pharmacy Technicians:

According tofederal law,a reverse distributor must issue a DEA Form 222 (or electronic equivalent) when a pharmacy requests the destruction of a Schedule II controlled substance.

Reverse distributorshandle the return and disposal ofexpired, damaged, or unusable controlled substances.

DEA Form 222 (or CSOS, the electronic equivalent) is required for Schedule II drugs.

Hydrocodone with acetaminophen (e.g., Norco, Vicodin)is aSchedule II controlled substance, requiringDEA Form 222for reverse distribution.

A. Acetaminophen with codeine❌→Schedule III

Does not require DEA Form 222; instead, DEA Form 41 is used for disposal.

C. Promethazine with codeine❌→Schedule V

Lower abuse potential; does not require DEA Form 222.

D. Pseudoephedrine with ibuprofen❌→Not a controlled substance

Pseudoephedrine is regulated under the Combat Methamphetamine Epidemic Act (CMEA), not the DEA controlled substance schedules.

DEA Controlled Substances Act (CSA)– Confirms thatSchedule II drugs require DEA Form 222 for reverse distribution.

PTCB PTCE Exam Content Outline– Covers controlled substances and reverse distribution requirements.

DEA Diversion Control Division Guidelines– Listshydrocodone as a Schedule II drug requiring Form 222 for disposal.

Understanding DEA Form 222 and Reverse Distribution:Why is Hydrocodone with Acetaminophen the Correct Answer?Why Not the Other Options?Key References:

A reverse distributor is an entity authorized to receive, manage, and dispose of outdated, damaged, or unusable medications from pharmacies, including coordinating credits and compliant destruction. A secondary wholesaler resells products but does not primarily manage disposal. A cancer drug repository is a donation program in some states—not a disposal service. A prime vendor is the contracted primary wholesaler for routine purchasing, not for expired drug destruction.

• Pharmacy inventory management operations: definitions and roles of wholesalers vs. reverse distributors; expired drug handling.

• DEA/State guidance on handling returns and disposal (reverse distribution) for prescription and controlled medications.

• PTCB/ExCPT study guides: reverse distribution and compliant destruction processes.

Controlled substances (Schedules I–V) are classified by the DEA based on their potential for abuse, medical use, and dependence risk.

Schedule I (highest risk, no medical use):Heroin, LSD, Ecstasy.

Schedule II (high abuse potential, medical use):Oxycodone, Morphine, Fentanyl.

Schedule III (moderate abuse potential):Codeine combinations, Ketamine.

Schedule IV (low abuse potential):Alprazolam, Zolpidem.

Schedule V (lowest risk):Cough syrups with low doses of codeine.

Why Other Options Are Incorrect:

B. All contain hydrocodone?❌OnlySchedule II and IIImay contain hydrocodone.

C. FDA-approved indications?❌Schedule I drugs haveno FDA-approved medical use.

D. Insurance verification?❌Not all controlled drugs require insurance verification.

???? Reference:DEA Controlled Substance Act, PTCB Controlled Substances Guide.

Under federal DEA requirements for transferring controlled substance prescriptions in Schedules III–V, the receiving pharmacist must document key original prescription details, including the date of original dispensing, the original date of issuance, the original number of refills authorized, the number of refills remaining, and pertinent information about the transferring pharmacy (name, address, DEA, and Rx number), as well as the name of the transferring pharmacist. Information such as the medication’s expiration date or the receiving pharmacy’s DEA number is not required to be newly noted by the receiving pharmacy for the transfer record. The prescriber’s DEA number is part of the original prescription, but federal transfer documentation specifically requires noting the original dispensing date rather than re-recording the prescriber’s DEA.

High-alert medications are those that bear a heightened risk of causing significant patient harm when used in error. Parenteral potassium chloride (KCl) for injection is a classic example on institutional high-alert lists due to the risk of fatal cardiac arrhythmias with inadvertent bolus administration, concentration mix-ups, or compounding errors. This designation is not based on name similarity (A), packaging color schemes (B), or prescribing preference (C), but on the severity of harm from errors.

Pharmacy technicians must ensure all critical patient safety information is present before processing, including allergy status. If allergy information is missing, the technician should consult the pharmacist immediately to determine next steps (e.g., hold processing, contact patient/prescriber) because dispensing without allergy screening poses a safety risk. While missing prescription elements like quantity or duration (D) do require clarification with the prescriber, triage and clinical judgment on how to proceed are pharmacist-directed. Items like the date/time written (A) and a prescriber fax number (C) are administrative and typically do not require pharmacist consultation during clinical data entry unless there is a legal validity concern.

References (Pharmacy Technician documents/Study Guides):

• ASHP/PTCB scope of practice: technician responsibilities include gathering and relaying information; pharmacists perform clinical judgment and verification.

• Community pharmacy workflow standards: allergy verification is a required safety step prior to filling.

• ISMP best practices: ensure allergy documentation and screening before medication processing and dispensing.

PTCB Dosage Conversions

eMAR/CPOE safety practices include setting automatic stop parameters such as a total number of doses or defined stop dates (e.g., for antibiotics), so therapy automatically discontinues when intended, preventing unnecessary or prolonged treatment. “Continuation orders” (Option B) extend therapy and do the opposite of preventing prolongation. Insurance information (A) and standard precautions (D) are unrelated to eMAR stop controls.

To calculate:

20 mEq per 15 mL

We need 40 mEq, so:

(40 mEq)÷(20 mEq)=2×15 mL=30 mL(40 \, \text{mEq}) \div (20 \, \text{mEq}) = 2 \times 15\, \text{mL} = 30\, \text{mL}(40mEq)÷(20mEq)=2×15mL=30mL

Now, convert to teaspoons:

1 tsp = 5 mL

30 mL ÷ 5 = 6 tsp

Lorazepam oral concentrate is a high-potency liquid formulation often dispensed in 2 mg/mL. Due to its strength and risk of dosing errors, it must be dispensed with a calibrated oral syringe for accurate dosing, especially in pediatric or geriatric patients.

From Pharmacy Technician Certification Exam Review:

“Concentrated oral liquids should always be dispensed with calibrated measuring devices to prevent overdose or underdose.”

Other options:

Enoxaparin – subcutaneous injection

Albuterol/ipratropium – inhalation

Polyethylene glycol 3350 – powder mixed with water (no syringe required)

Amoxicillin/clavulanate is a penicillin-class (β-lactam) antibiotic. Its labeling includes a contraindication in patients with a history of hypersensitivity to β-lactams (e.g., penicillins; often caution with cephalosporins due to cross-reactivity). Allergy to quinolones (B) is unrelated pharmacologically. Pregnancy or breastfeeding (C) is not an absolute contraindication (risk/benefit assessment is used). Hypertension (D) is not relevant. Therefore, beta-lactam hypersensitivity is the clear contraindication.

References (Pharmacy Technician documents/Study Guides):

• Drug labeling standards: contraindication for penicillin hypersensitivity in amoxicillin-containing products.

• ISMP safety guidance: allergy screening for β-lactam antibiotics.

Cytotoxic agents are drugs that kill or damage cells, particularly rapidly dividing cells. They are primarily used in the treatment of cancer (chemotherapy) because cancer cells multiply quickly. These medications interfere with cell division (mitosis), leading to cell death.

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

“Cytotoxic drugs are most commonly used in oncology. Their use requires special handling and storage protocols to protect healthcare workers and patients.”

Additional Notes:

Diabetes treatments involve insulin or oral antidiabetics, not cytotoxics.

Rosacea and allergies are treated with antimicrobials and antihistamines/steroids, respectively.

Under federal controlled substance recordkeeping requirements, pharmacies must maintain prescription records for controlled substances for at least 2 years from the date of last activity (e.g., last fill). This includes both original and transferred controlled prescriptions. While some states require longer retention, federal law establishes a minimum of 2 years.

References (Pharmacy Technician documents / Study Guides):

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.

Pharmacy staff should always visually inspect nonsterile compounds for signs of incompatibility to ensure medication safety and efficacy. The presence ofprecipitationis a key indicator of an incompatibility issue in nonsterile compounded preparations. Precipitation occurs when a solute (drug) comes out of solution, forming visible solid particles. This can result from changes in pH, solvent composition, or chemical interactions between ingredients.

A. Photolysis:

Decomposition of a drug due to light exposure, leading to color changes or potency loss, but it is not a physical incompatibility visible as precipitation.

B. Hydrolysis:

Chemical breakdown of a drug due to water, common in ester and amide-containing drugs, but not a visual incompatibility like precipitation.

Dilution formula:C₁V₁ = C₂V₂

C₁ = 20%, V₁ = 100 mL, C₂ = 2%

(20)(100) = (2)(V₂) → V₂ = 1000 mL(final volume after dilution).

Convert to oz:1000 mL ÷ 59 mL (2 oz) = 16 bottles.
