The Pharmacy Technician Certification (CPhT) Exam (PTCE)

• The prescribed dose is 2 teaspoons per dose, which equals 10 mL (1 tsp = 5 mL). Therefore, the most appropriate device is a 10 mL oral syringe, which allows accurate measurement of the full dose in a single draw and provides superior dosing accuracy compared with household spoons or cups.

• Pharmacy technician training materials and medication safety guidance emphasize that oral syringes are preferred over cups for pediatric and liquid medications due to greater accuracy, especially when doses are measured in mL.

• Why the other options are not best:

– 1 mL oral syringe (A): Too small; would require 10 fills per dose, increasing error risk.

– 1 oz dosage cup (C): 1 oz = 30 mL; cups are less accurate for small/precise volumes and increase risk of mismeasurement.

– 1 tbsp dropper (D): Droppers are not suitable for large volumes; tablespoon is 15 mL and mismatched to the 10 mL dose.

Comprehensive and Detailed Step-by-Step Explanation:

Clozapine (Clozaril)is anatypical antipsychoticused to treatschizophrenia. However, it has a severe side effect calledagranulocytosis, which causesa dangerous drop in white blood cells (WBCs) and neutrophils (ANCs), increasing the risk of infections.

???? Explanation of Answer Choices:✅D. Clozapine→Correct.Patients must be enrolled in theClozapine REMS program, and pharmacies must verifyANC and WBC resultsbefore dispensing.❌A. Aripiprazole→ Incorrect.Aripiprazole (Abilify) does not require ANC monitoring.❌B. Fluoxetine→ Incorrect.Fluoxetine (Prozac) is an SSRI and does not require blood monitoring.❌C. Amitriptyline→ Incorrect.Amitriptyline is a tricyclic antidepressant and does not require ANC monitoring.

PTCB Exam: Medication Safety & Risk Evaluation

To determine theweight/weight (w/w) percentage strength, use the formula:

\text{w/w % strength} = \left( \frac{\text{Mass of Active Ingredient (g)}}{\text{Total Mass of Final Product (g)}} \right) \times 100

Given:

Mass of zinc oxide (active ingredient) = 4.5 g

Total mass of final ointment = 30 g

\text{w/w % strength} = \left( \frac{4.5}{30} \right) \times 100 =0.15×100= 0.15 \times 100=0.15×100 =15%= 15\%=15%

(A) 0.25%❌Incorrect – This is too low.

(B) 10%❌Incorrect – This would be true if 3 g of zinc oxide were used in 30 g total.

(C) 15%✅Correct – The calculation confirms this answer.

(D) 17.5%❌Incorrect – This would be true if 5.25 g of zinc oxide were used in 30 g total.

Analysis of Answer Choices:References for Pharmacy Technicians:

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.

TheDrug Enforcement Administration (DEA)requires that theft or significant loss ofcontrolled substancesbe reported usingDEA Form 106.

(A) Pregabalin✅Schedule V (Controlled Substance – Must be Reported to DEA)

Pregabalin (brand name:Lyrica) is classified as aSchedule V controlled substanceunder theControlled Substances Act (CSA).

Pharmacies must report its theft or significant loss to the DEA using DEA Form 106.

(B) Piroxicam❌Not a Controlled Substance – No Reporting Required

Piroxicam is anonsteroidal anti-inflammatory drug (NSAID).

It isnot a controlled substance, so DEA reporting isnot requiredfor theft or loss.

(C) Prochlorperazine❌Not a Controlled Substance – No Reporting Required

Prochlorperazine is anantiemetic and antipsychotic.

It isnot a controlled substance, so DEA reporting isnot requiredfor theft or loss.

(D) Pioglitazone❌Not a Controlled Substance – No Reporting Required

Pioglitazone (brand name:Actos) is anantidiabetic medication (thiazolidinedione).

It isnot a controlled substance, so DEA reporting isnot requiredfor theft or loss.

Thepharmacist-in-charge (PIC)must fileDEA Form 106in the event of a significant loss or theft of anySchedule II–V controlled substance.

The loss must be reportedwithin one business dayto theDEAand local law enforcement.

Minor losses due to inventory miscounts do not require DEA reporting but should be documented internally.

Controlled Substance Classification of Each Drug:DEA Reporting Requirements for Pharmacy Technicians:References for Pharmacy Technicians:

For aqueous solutions such as water, proper volumetric technique requires placing the graduated cylinder at eye level and reading the bottom of the meniscus to avoid parallax error and obtain an accurate measurement. Reading at the top of the meniscus or holding the cylinder above eye level produces inaccurate results. This technique is standard in compounding and measurement guidance used in pharmacy training.

References (Pharmacy Technician documents/Study Guides):

• USP < 795 > Pharmaceutical Compounding—Nonsterile Preparations: Accurate measurement and meniscus reading for liquids.

• USP general laboratory technique guidance used in pharmacy education (volumetric measurement best practices).

• PTCB/ExCPT Compounding sections: Use of graduated cylinders and meniscus reading.

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.

• USP < 800 > Hazardous Drugs—Handling in Healthcare Settings: personnel training expectations and references to OSHA standards for safe handling.

• OSHA Hazard Communication Standard and HAZWOPER training requirements as cited in pharm tech safety modules.

Chemotherapy drugs (e.g., methotrexate, cisplatin)arehigh-alertdue to theirtoxicity, risk of overdose, and narrow therapeutic index.
