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.

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.

TheFDA classifies recalls into three levels, withClass III being the least severe:

Class I Recall→Most severe→ Issued when a drugmay cause serious harm or death.

Class II Recall→Moderate severity→ The drug may causetemporary or medically reversible adverse effects.

Class III Recall→Least severe→ The productis unlikely to cause harm but violates FDA regulations(e.g., labeling errors, minor packaging issues).

A. Is issued when there is a reasonable probability that the product will cause serious adverse health consequences or death.❌→Incorrect

Describes a Class I recall, not Class III.

B. Is initiated by the FDA if a manufacturer has violated the adulteration provisions of the Food, Drug, and Cosmetic Act (FDCA).❌→Incorrect

FDA action due to adulteration typically leads to Class I or Class II recalls, depending on severity.

C. Occurs when a product may cause temporary or medically reversible adverse health consequences.❌→Incorrect

Describes a Class II recall, not Class III.

FDA Drug Recall Guidelines– Defines Class I, II, and III recalls.

PTCB PTCE Exam Content Outline– Covers recall classifications and pharmacy responsibilities.
