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.

NIOSH Guidelines on PPE for Hazardous Drugs

According toCDC Hand Hygiene Guidelines, pharmacy technicians should wash their hands withsoap and waterinstead of alcohol-based hand sanitizer when:

Hands are visibly dirty→ Alcohol-based sanitizers are ineffective against certain contaminants like dirt, grease, and some bacteria.

Before eating→ Prevents ingestion of harmful pathogens.

After using the restroom→ Soap and water are required to remove potential fecal contamination.

A. They have time, before eating, and after eating❌→Incorrect

Handwashing ismandatorywhen hands are dirty or after using the restroom, not just when there's time.

B. Their hands are visibly clean, after eating, and before each patient❌→Incorrect

Washing isnot required if hands appear clean—sanitizer is acceptable in most situations except when visibly soiled.

C. They have finished filling prescriptions, before eating, and after each patient❌→Incorrect

Hand hygiene is important, but hand sanitizer is typically used between patients unless hands are visibly dirty.

CDC Hand Hygiene in Healthcare Settings– Recommendssoap and waterfor visibly soiled hands and after restroom use.

USP <797> Guidelines for Aseptic Technique– Emphasizes proper handwashing for sterile compounding.

PTCB PTCE Exam Content Outline– Covers infection control and hand hygiene protocols.

Why Not the Other Options?Key References:

When a voluntary, nonpunitive medication error reporting system is introduced and safety culture improves, organizations commonly see an initial rise in reported errors. This does not necessarily mean more errors are occurring; rather, more errors are being reported due to increased staff comfort and encouragement to report. Punitive cultures (B) reduce reporting, not increase it. Distraction from dispensing (C) or false reporting (D) are not recognized primary drivers of such patterns in patient safety literature.

References (Pharmacy Technician documents / Study Guides):

• ISMP and AHRQ patient safety culture principles: nonpunitive, learning-focused reporting increases the number of reported events initially.

• NCC MERP recommendations on error reporting and safety culture.

• Pharmacy safety and quality improvement modules in PTCB/ExCPT study guides: trends in reporting after implementing voluntary systems.
