PTCB PTCE - Pharmacy Technician Certification (CPhT) Exam

Prilosec (Omeprazole) is a delayed-release proton pump inhibitor (PPI)used forGERD, ulcers, and acid reflux. It comes incapsulescontainingenteric-coated granules, designed to protect the medication from stomach acid and ensure proper absorption.

Prilosec capsules contain enteric-coated granulesthat are safe to sprinkle on soft foodswithout chewing.

Applesauce is an ideal optionbecause it doesnot interfere with drug absorption or stability.

B. Chew and swallow the capsules❌→ Incorrect

Chewing destroys the enteric coating, leading to premature drug release and degradation by stomach acid.

C. Compound the capsules into a topical preparation❌→ Incorrect

Prilosecis not formulated for topical use. The medication must reach the stomach intact for proper effect.

D. Allow the capsules to dissolve under the tongue❌→ Incorrect

Sublingual administration is ineffectivebecauseomeprazole is not absorbed through the mucous membranesand needs enteric protection.

FDA Omeprazole Medication Guide– States that the contents can be sprinkled on applesauce.

ISMP Safe Medication Use Guidelines– Emphasizes proper administration of delayed-release capsules.

PTCB PTCE Exam Content Outline– Covers modified-release formulations and proper drug administration techniques.

Why Can the Capsules Be Opened?Why Not the Other Options?Key References:

TheVaccine Adverse Event Reporting System (VAERS)is a national system managed by theCDC and FDAto monitoradverse events following vaccination.

Anaphylaxisis asevere, life-threatening allergic reactionthat must beimmediately reported to VAERS, as it is a known but rareserious vaccine side effect.

Other serious events likeGuillain-Barré syndrome, myocarditis, and seizuresalso require VAERS reporting.

A. Constipation→ Incorrect;not a serious vaccine-related event.

C. Drowsiness→ Incorrect; commonbut not severeenough to require VAERS reporting.

D. Hyperlipidemia→ Incorrect;unrelated to vaccines.

Comprehensive and Detailed Step-by-Step Explanation:

Hazardous drugs (HDs)must be handled withpersonal protective equipment (PPE), including:

Gloves (chemotherapy-rated)

Gown (disposable, impermeable material)

Eye protection (if splashing risk exists)

Respirator (if airborne exposure is possible)

📌Explanation of Answer Choices:✅B. Wearing personal protective equipment→Correct.USP <800> mandatesPPEfor handling hazardous drugs.❌A. In a chemical safety cabinet→ Incorrect.Only sterile hazardous drugs require a biological safety cabinet.❌C. Using disposable gloves washed between each use→ Incorrect.Disposable gloves should be discarded, not washed.❌D. In a positive-pressure clean room→ Incorrect.Hazardous drugs require negative pressure rooms, not positive pressure.

📌Reference:

USP <800>: Hazardous Drug Handling

NIOSH Guidelines on PPE for Hazardous Drugs

Vistaril = Hydroxyzine, anantihistamine used for anxiety, nausea, and allergies.

Meclizine (Antivert) is also an antihistaminebut is used primarily formotion sickness and vertigo.

📌Reference:FDA Approved Drug List, PTCE Medication Guide.

Asmanex HFA (Mometasone) is an inhaled corticosteroid used for asthma.

A spacer improves medication delivery by holding the medication in a chamber, allowing better lung absorption.

This is especially important for children and elderly patients.

Why Other Options Are Incorrect:

A. Nebulizer?❌Not needed for an HFA inhaler; used for liquid medications.

C. Ventilator?❌Used for mechanical breathing, not asthma maintenance.

D. Glucometer?❌Used for blood sugar monitoring, unrelated to inhalers.

📌Reference:Global Initiative for Asthma (GINA) Guidelines, PTCB Respiratory Medication Guidelines.

Percocet (oxycodone/acetaminophen) and Tylenol (acetaminophen)should be avoided together becauseboth contain acetaminophen.

High doses of acetaminophen (>4,000 mg/day in adults)can causesevere liver toxicity, leading to acute liver failure.

Acetaminophen is metabolized by theliver enzyme CYP2E1, producingtoxic metabolitesthat, in excess, overwhelm the liver’s ability to detoxify them.

Why Other Options Are Incorrect:

Motrin (ibuprofen) + Ativan (lorazepam):No liver toxicity risk.✅

Motrin (ibuprofen) + Tylenol (acetaminophen):Not inherently dangerous but can causeGI bleedingandkidney damagewith long-term use.

Percocet (oxycodone/acetaminophen) + Ativan (lorazepam):Risk ofCNS depression, butnotliver toxicity.

📌Reference:FDA Acetaminophen Safety Guidelines,CDC Liver Toxicity Warnings.

TheInstitute for Safe Medication Practices (ISMP)maintains a list oferror-prone abbreviationsthat shouldnot be usedin medication orders to prevent misinterpretation and medication errors.

Analysis of the Answer Choices:Abbreviation

Meaning

ISMP Recommendation

U

Units

❌Do NOT use→ Can be mistaken for "0" or "4" (e.g., 10U could be misread as 100).Use"unit"instead.

AD

Right ear

❌Do NOT use→ Can be confused with "OD" (right eye).Use"right ear"instead.

AU

Both ears

❌Do NOT use→ Can be confused with "OU" (both eyes).Use"both ears"instead.

gtt

Drop

✅Accepted→ Common and not considered error-prone.

Since"gtt" for drop is not on ISMP's "Do Not Use" list, it is the correct answer.

ISMP List of Error-Prone Abbreviations– Confirms that "U," "AD," and "AU" should not be used in prescriptions.

Joint Commission "Do Not Use" List– Prohibits "U" and similar abbreviations to prevent dosing errors.

PTCB PTCE Exam Content Outline– Covers error prevention strategies, including abbreviation safety.

Needlegauge (G)refers to thediameter of the needle’s lumen(opening).The higher the gauge number, the smaller the needle diameter.

Lower gauge (e.g., 13G, 18G)→Larger needle(wider opening)

Higher gauge (e.g., 27G)→Smaller needle(narrower opening)

Common Needle Gauges and Their Uses:Gauge (G)

Needle Diameter (mm)

Common Use

13G

2.4 mm

IV drug administration (large-bore)

18G

1.2 mm

Drawing thick medications (e.g., oil-based injections)

20G

0.9 mm

General intramuscular (IM) injections

27G

0.4 mm

Subcutaneous (SC) or intradermal (ID) injections (e.g., insulin, vaccines)

Since27Gis the highest gauge listed, it corresponds to thesmallestneedle diameter, making it the correct answer.

A. 13G❌→ One of the largest gauges, used for IV fluids or blood transfusions.

B. 18G❌→ Large needle used for thick medications likedepot injections or contrast agents.

C. 20G❌→ Common forintramuscular injectionsbut larger than 27G.

PTCB PTCE Exam Content Outline– Covers needle gauges, injection routes, and proper medication administration.

USP <797> & USP <800>– Provide sterile compounding guidelines, including appropriate needle gauge selection.

CDC Vaccine Administration Guidelines– Recommend25-30Gfor subcutaneous and intradermal injections.

Diflucan (fluconazole) is an antifungal, whileDiprivan (propofol) is a sedative/anesthetic used for surgery.

Look-Alike, Sound-Alike (LASA) errorsoccur when medications havesimilar names but different indications.

Why Other Options Are Incorrect:

B. Clonidine (BP medication) & Klonopin (anxiolytic)→ LASA error but not antifungal vs. anesthetic.

C. Metronidazole (antibiotic) & Metformin (diabetes drug)→ LASA error but different categories.

D. Amiloride (diuretic) & Amlodipine (BP medication)→ LASA error but different categories.
