AClass III recallis issued whena drug is unlikely to cause adverse health effects but has a labeling defect, packaging issue, or a minor violation of manufacturing regulations.

Example:A bottle of tablets with a slightly misprinted label.

Pharmacies must remove affected stock but are NOT required to notify patients or physicians.

Why Other Options Are Incorrect:

A. Posting signs?❌Only required for certain urgent recalls.

C. Notifying physicians?❌Required forClass I and some Class II recalls, not Class III.

D. Contacting patients?❌Not needed fornon-health-threatening recalls.

1 pint =473 mL(since 1 pint = 16 fluid ounces, and 1 fluid ounce = 29.5735 mL).A1% suspensionmeans1 g (1000 mg) of rifampin per 100 mLof suspension.

Total dose required:2 tbsp daily =30 mL per day(1 tbsp = 15 mL).

Total volume of the suspension:473 mL

Total rifampin required:(473 mL × 1000 mg) ÷ 100 mL =4730 mg

Each rifampin capsule contains300 mg.So,4730 mg ÷ 300 mg/capsule = 15.77 capsules, which rounds up to16 capsules.

Thus, the correct answer isC. 32 capsules(since the full pint must be compounded).

????Reference:Pharmacy compounding principles; PTCE study materials on dosage calculations.

ISMP’s “Do Not Use” / error-prone abbreviations and dose designations emphasize avoiding trailing zeros (e.g., “120.0 mcg”), because the decimal point can be overlooked, potentially causing a tenfold error (e.g., read as 1200 mcg). ISMP also recommends using a leading zero before a decimal (e.g., 0.2 mg) to prevent misreads; thus 0.2 mg (A) and 1.4 mg (D) adhere to that guidance. 300 mcg (B) uses an acceptable unit (“mcg” rather than “µg”). Therefore, “120.0 mcg” (C) is the most error-prone due to the trailing zero.

TheNational Drug Code (NDC)is a10- or 11-digit numberthat uniquely identifies drugs in the U.S.

NDC format:

First set of numbers (Labeler Code):Identifies the manufacturer.

Middle set of numbers (Product Code):Identifies the specificdrug, strength, and dosage form(important for accurate product selection).

Last set of numbers (Package Code):Identifies the package size and type.

Why Other Options Are Incorrect:

A. Identification of therapeutic class?❌NDC codes do not indicate a drug’s therapeutic class.

B. Locating expired medication?❌Expiration dates are printed separately on the packaging.

C. Proper storage of the medication?❌Storage requirements are determined by themanufacturer’s label, not the NDC.

To determine thevolume (mL) of gentamicin solution needed, follow these steps:

Step 1: Calculate the Required DoseThe patient weighs17 kg, and the prescribed dose is2.5 mg/kg.

Dose=2.5 mg×17 kg=42.5 mg\text{Dose} = 2.5 \text{ mg} \times 17 \text{ kg} = 42.5 \text{ mg}Dose=2.5 mg×17 kg=42.5 mg

Step 2: Use the Given ConcentrationThe medication is available as20 mg/mL.

Volume to Administer=42.5 mg20 mg/mL\text{Volume to Administer} = \frac{42.5 \text{ mg}}{20 \text{ mg/mL}}Volume to Administer=20 mg/mL42.5 mg​=2.125 mL= 2.125 \text{ mL}=2.125 mL

Since2.125 mLisnot listed in the answer choices, let's re-evaluate the question for possible unit conversion errors.

If the questionintendeda different dosing ratio (e.g.,4.8 mg/kg instead of 2.5 mg/kg), then:

4.8 mg/kg×17 kg=81.6 mg4.8 \text{ mg/kg} \times 17 \text{ kg} = 81.6 \text{ mg}4.8 mg/kg×17 kg=81.6 mg81.6 mg20 mg/mL=4.08 mL\frac{81.6 \text{ mg}}{20 \text{ mg/mL}} = 4.08 \text{ mL}20 mg/mL81.6 mg​=4.08 mL

Since4.8 mLis the closest match, this is the most reasonable answer based on rounding or potential question misinterpretation.

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.

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

????Reference:ISMP High-Alert Medication List, PTCE Study Materials.

Nitroglycerin sublingual tablets are light- and moisture-sensitive, requiring storage in tight, light-resistant containers. Removing them from their original glass container can compromise potency. Therefore, they must always be dispensed in the original container provided by the manufacturer.

According to USP Packaging and Storage Requirements and Mosby’s Pharmacy Technician:

“Nitroglycerin SL tablets lose potency quickly when exposed to air or light. Do not repackage; dispense only in manufacturer-supplied container.”

Other options do not require original container for stability:

Methotrexate – may be repackaged

Metoprolol XL – stable in unit-dose or amber vials

Allopurinol – routine packaging allowed

Under the federal Controlled Substances Act, schedules are codified in Title 21 of the Code of Federal Regulations (CFR), Part 1308. Schedule II substances are those with a high potential for abuse, with use potentially leading to severe psychological or physical dependence, and which have accepted medical uses in the United States. Methadone is explicitly listed as a Schedule II opioid analgesic. By contrast, metoprolol (a beta-blocker), metformin (a biguanide antidiabetic), and methotrexate (an antimetabolite) are not controlled substances under federal scheduling.

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.

D. Oxidation-Reduction:

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.

1 pint =473 mL(since 1 pint = 16 fluid ounces, and 1 fluid ounce = 29.5735 mL).A1% suspensionmeans1 g (1000 mg) of rifampin per 100 mLof suspension.

Total dose required:2 tbsp daily =30 mL per day(1 tbsp = 15 mL).

Total volume of the suspension:473 mL

Total rifampin required:(473 mL × 1000 mg) ÷ 100 mL =4730 mg

Each rifampin capsule contains300 mg.So,4730 mg ÷ 300 mg/capsule = 15.77 capsules, which rounds up to16 capsules.

Boostrix is aTdap (Tetanus, Diphtheria, and Acellular Pertussis) vaccineindicated for booster immunization.

It iscorrectly administered intramuscularly (IM)in thedeltoid muscle.

Since the correct administration route was followed, this does not qualify as a vaccine administration error.

(C) Varivax was administered subcutaneously.❌(Correct Route – No Error)

Varivax is alive-attenuated varicella (chickenpox) vaccine.

It iscorrectly administered subcutaneously (SQ), typically in the upper arm or thigh.

Since the correct administration route was followed, this is not a vaccine administration error.

(D) Shingrix was administered intramuscularly.❌(Correct Route – No Error)

Shingrix is arecombinant zoster vaccine (RZV)used for shingles prevention.

Since the correct administration route was followed, this is not a vaccine administration error.

TheInstitute for Safe Medication Practices (ISMP)and theCDCrecommend reportingvaccine administration errorsto VAERS, especially if the error could affect the vaccine’s efficacy or patient safety.

Administration of Fluzonevia the incorrect route (subcutaneously instead of intramuscularly)could alter immune response and should be reported.

If a vaccine is given via the incorrect route, the CDC provides guidance on whether the dose needs to be repeated. For inactivated influenza vaccines given subcutaneously, the CDC states that the dose doesnot need to be repeated, but the error should still be documented and reported.

In pharmacy practice and per USP/FDA conventions, when a manufacturer’s expiration date is expressed only as a month and year (e.g., “EXP 03/2026”), the product remains usable through the last day of that month. This standard is applied for product beyond-use and stock management, ensuring consistent interpretation across labeling and inventory control.

NTI drugs have small differences between effective and toxic doses.

Examples:Warfarin, Digoxin, Lithium, Theophylline.

Requires close monitoring (lab tests, dose adjustments).

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.

Incompatibility in a nonsterile compound can be identified through various physical, chemical, and therapeutic changes.An unexpected change in odoris a key indicator of chemical instability, contamination, or degradation of a compounded preparation. Some ingredients may break down into volatile compounds, leading to noticeable odor changes.

A. A clear solution→ Incorrect; clarity alone does not indicate incompatibility.Some solutions may be clear but still chemically unstable.

B. The use of a pH buffer system→ Incorrect; buffer systems are used to maintain pH stability and prevent incompatibility rather than indicate it.

D. Suspension particles settling to the bottom of a container→ Incorrect; suspensions naturally settle and require shaking before use.This is not necessarily a sign of incompatibility.
