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.

????Reference:ISMP List of High-Risk LASA Medications.

AUstands for"auris utraque", meaning"both ears".✅

Sig codes (Signa codes)are abbreviations used in prescriptions to indicate how a medication should be taken or applied.

Why Other Options Are Incorrect:

q.s. (quantum satis):Means "a sufficient quantity," NOT"shake well."❌

IN:Refers tointranasal, NOTintramuscular (IM).❌

q.i.d. (quater in die):Means"four times a day,"NOT"three times a day".❌

????Reference:PTCB Official Sig Code List,Institute for Safe Medication Practices (ISMP) Approved Abbreviations.

The abbreviation"PO"means"by mouth" (per os).

The abbreviation"ac"stands for"before meals" (ante cibum).

The phrase"daily for 14 days"indicates that the patient should take the medication once a day for a total of 14 days.

Thus, the correct label instructions should be:"Take one capsule by mouth before a meal once daily for 14 days."

PTCB PTCE Exam Content Outline – Prescription Interpretation– Covers standard medical abbreviations.

ISMP (Institute for Safe Medication Practices) List of Common Pharmacy Abbreviations– Defines "PO" (by mouth) and "ac" (before meals).

To determine how muchdrug (active ingredient)is in2 oz (ounces) of cream, we use the given ratio and perform unit conversions.

120 gof cream contains3 gof drug.

2 ozof cream =2 × 28.35 g(since1 oz = 28.35 g)

2 oz = 56.7 g

Step 1: Identify Given DataStep 2: Set Up a Proportion3 g drug120 g cream=x g drug56.7 g cream\frac{3 \text{ g drug}}{120 \text{ g cream}} = \frac{x \text{ g drug}}{56.7 \text{ g cream}}120 g cream3 g drug​=56.7 g creamx g drug​

Step 3: Solve forxxxx=3×56.7120=170.1120=1.42≈1.5 gx = \frac{3 \times 56.7}{120} = \frac{170.1}{120} = 1.42 \approx 1.5 \text{ g}x=1203×56.7​=120170.1​=1.42≈1.5 g

Thus,1.5 g of drugis present in2 oz of cream.

B. 6 g→ Incorrect; this would assume a higher drug concentration.

C. 15 g→ Incorrect; this is a miscalculation of the ratio.

D. 60 g→ Incorrect; far exceeds the total weight of the cream.

Risedronate (Actonel)is abisphosphonateused to treat osteoporosis.

Bisphosphonates can causesevere esophagitis and esophageal ulcersif not taken properly.

Patients must take the medication witha full glass of waterand remainupright for at least 30 minutesafter administration to reduce esophageal irritation.

Other medications in the options:

Ropinirole: A dopamine agonist for Parkinson’s disease; no such requirement.

Repaglinide: A meglitinide for diabetes; no such requirement.

Rifampin: An antibiotic for tuberculosis; no such requirement.

????Reference:PTCE study materials; drug administration guidelines forbisphosphonates.

Total daily dose = 23 units (AM) + 17 units (PM) = 40 units/day

60 days × 40 units = 2,400 units needed

Each NPH insulin vial contains 1,000 units (10 mL × 100 units/mL)

2,400 units ÷ 1,000 units/vial = 2.4 vials → round up to 3 vials

From Pharmacy Technician Certification Exam Review:

“When calculating insulin quantities, always round up to ensure the patient has sufficient supply. Insulin is typically dispensed in 10 mL vials containing 100 units/mL.”

A medication'sstabilityrefers tohow well it maintains potency, effectiveness, and safety over time. Several factors candegrade medications, includingoxygen, moisture, temperature, and light.

Oxygen exposurecan causeoxidation, leading to drug degradation and loss of potency.

Many medications, especiallyvitamins (e.g., vitamin C), biologics, and certain antibiotics, are susceptible to oxidative damage.

Medications requiring protection from oxygen are often packaged inair-tight containersorblister packs.

A. Allergies→ Incorrect; allergies affect thepatient, not the drug’sstability.

B. Equivalence→ Incorrect; equivalence refers tobioavailabilitybetween generic and brand-name drugs, not drug stability.

D. Indications→ Incorrect; indications refer toapproved uses of a drug, not factors affecting its stability.

Methotrexateis achemotherapy agentand animmunosuppressantused for cancer and autoimmune diseases.

It is classified ashazardous pharmaceutical wasteunderResource Conservation and Recovery Act (RCRA)due to itstoxicity.

It must be disposed of followingEPA guidelines for hazardous waste disposal.

????Reference:RCRA hazardous waste disposal regulations;USP <800> guidelines for hazardous drugs.

According toUSP Chapter <800>(Hazardous Drugs—Handling in Healthcare Settings), solid oral dosage forms ofantineoplastic hazardous drugs (e.g., chemotherapy medications like methotrexate or tamoxifen)shouldnotbe placed inautomated counting or packaging machinesbecause:

Risk of Contamination– Tablets and capsulesmay generate dust or powder residue, which can spread hazardous drug particles into the environment.

Exposure Risks– Pharmacy staff may beexposed to hazardous particleswhen refilling, cleaning, or maintaining the machine. This poses a risk ofinhalation, dermal exposure, or accidental ingestion.

Strict USP <800> Compliance– Hazardous drugs requirespecial handling precautions, includingdesignated counting trays, dedicated equipment, and proper personal protective equipment (PPE). Automated machinesdo not provide the necessary containmentfor hazardous drug particles.

USP Chapter <800>– Mandates specific safety measures for handling hazardous drugs in pharmacies, including avoiding automated dispensing systems for hazardous solids.

NIOSH (National Institute for Occupational Safety and Health) List of Hazardous Drugs– Identifies drugs requiring special handling to minimize occupational exposure.

OSHA (Occupational Safety and Health Administration) Hazardous Drug Guidelines– Reinforces the need to prevent aerosolization of hazardous drug particles.

PTCB PTCE Exam Content Outline– Covers hazardous drug handling, personal protective equipment (PPE), and compliance with USP <800>.

Key References:????Why Not the Other Options?

A. Require a sterile environment❌→ Tablets and capsules arenon-steriledosage forms, and USP <800> focuses on hazardous drug containment rather than sterility.

B. Are often involved in dispensing errors❌→ While hazardous drugs must be dispensed carefully,dispensing errors are not the main reason for avoiding automated machines.

D. Expire sooner than other medications❌→ Expiration dates are unrelated tohazardous drug contamination risks.
