- To prevent cross-contamination between different medications, how often should a counting tray be cleaned?
Answer: After counting each different drug.
Best practice for infection and contamination control is to clean the counting tray and spatula with 70% isopropyl alcohol after every use, especially when switching between different drugs. This prevents drug residue from one medication from contaminating the next, which is crucial for patient safety.
- A pharmacy technician is required to wear personal protective equipment (PPE) including a gown and gloves while handling a hazardous drug. To prevent self-contamination, what is the correct sequence for removing this PPE?
Answer: Remove gloves, then remove gown.
The most contaminated item of PPE, the gloves, should be removed first. This prevents the technician from touching their clothing or skin with the contaminated gloves while removing the gown. After removing gloves and performing hand hygiene, the gown can be removed more safely.
- A pharmacy uses a new automated dispensing cabinet. What infection prevention consideration is most important regarding this equipment?
Answer: Following a regular schedule for cleaning the machine's drawers and surfaces.
Automated dispensing cabinets have many high-touch surfaces and areas where drug dust can accumulate. To prevent cross-contamination and the spread of infection, it is essential to have and follow a routine cleaning and disinfection schedule for all parts of the machine that technicians and pharmacists touch, as well as the cassettes and drawers that hold medication.
- When wearing a gown and gloves for handling hazardous materials, how should the gloves be worn to provide maximum protection?
Answer: Over the cuffs of the gown.
To create a complete barrier and prevent any skin exposure at the wrist, gloves should be pulled on over the cuffs of the gown. This ensures that no hazardous substance can get onto the skin between the end of the sleeve and the start of the glove.
- When should a pharmacy technician change their disposable gloves during the prescription filling process?
Answer: After handling a patient's insurance card and before handling medications.
Gloves should be changed when moving from a potentially contaminated task (like handling money or patient cards) to a clean task (like handling medications). This prevents the transfer of germs to the patient's medication. Relying only on visible soiling is insufficient, as gloves can be contaminated with invisible microorganisms.
- While counting tablets for a prescription, a pharmacy technician accidentally drops a tablet on the pharmacy floor. What is the correct action to take?
Answer: Pick up the tablet, discard it in the appropriate waste container, and continue counting.
Medication that has come into contact with the floor is considered contaminated and must not be dispensed. The correct procedure is to discard the tablet according to pharmacy policy (e.g., in a non-hazardous drug waste bin) and clean the hands before continuing the filling process. Attempting to clean the tablet is not sufficient to ensure it is safe for consumption.
- Which personal hygiene practice is most effective for preventing contamination of pharmacy work surfaces and sterile products from hair?
Answer: Tying back long hair and/or wearing a hair cover.
Hair can carry microorganisms and shed, potentially contaminating medications and work areas. The most effective control measure is to physically restrain hair by tying it back or containing it with a hair cover (bouffant cap), which is a standard requirement in cleanrooms and recommended in general dispensing areas.
- Why are personal items such as smartphones and keys considered a contamination risk in the direct prescription filling area?
Answer: They can harbor microorganisms and are not regularly disinfected.
Personal items are high-touch surfaces that are carried into various environments and are rarely cleaned to healthcare standards. They can act as fomites, transferring bacteria and viruses to hands, work surfaces, and ultimately to patient medications, posing a significant cross-contamination risk. While they can be distracting, the primary concern in this context is infection control.
- A technician is preparing to reconstitute a powdered antibiotic. Which piece of personal protective equipment (PPE) is most important to wear to prevent inhalation of drug particles?
Answer: Mask
When handling drug powders that can be aerosolized, such as during reconstitution, wearing a mask is essential to prevent inhalation of the particles. This protects the technician from potential respiratory irritation or allergic reaction. While other PPE may be required depending on the drug's hazardous nature, a mask directly addresses the inhalation risk.
- Which of the following is considered a critical step in infection prevention that a pharmacy technician must perform immediately after using the restroom and before returning to any prescription-filling duties?
Answer: Thoroughly washing hands with soap and water.
After using the restroom, hands are likely to be contaminated with microorganisms such as C. difficile, which are not effectively killed by alcohol-based sanitizers. Therefore, thorough handwashing with soap and water is mandatory to remove potential pathogens before resuming any pharmacy tasks.
- What is the most appropriate agent to use for cleaning the equipment to prevent cross-contamination?
Answer: 70% isopropyl alcohol
70% isopropyl alcohol is the standard cleaning agent for counting trays and equipment between prescriptions. It effectively removes drug residue and disinfects the surface, which is critical for preventing cross-contamination, especially with drugs like sulfa that can cause severe allergic reactions. Water alone or dry gauze is insufficient for removing all residue and sanitizing the equipment.
- A patient returns a medication to the pharmacy, stating they received the wrong drug. The vial has been opened. What is the correct infection control procedure for this medication?
Answer: Immediately quarantine the medication for proper disposal.
Once a medication has left the pharmacy and been in a patient's possession, its integrity and sterility can no longer be guaranteed, even if unopened. It is considered contaminated and must never be returned to stock or dispensed to another patient. The correct procedure is to quarantine it for disposal according to state and federal regulations.
- A technician observes a coworker apply alcohol-based hand sanitizer to their hands which are visibly soiled with drug powder. Why is this action incorrect?
Answer: Sanitizers are less effective when hands are visibly dirty or greasy.
Alcohol-based hand sanitizers are not designed to be effective on hands that are visibly soiled with dirt, grime, or other materials like drug powder. The organic matter interferes with the alcohol's ability to kill microorganisms. In such cases, the correct procedure is to wash hands with soap and water.
- A pharmacy technician is cleaning the dispensing countertop at the end of the day. A small spill of a non-hazardous liquid medication (e.g., a cough syrup) has dried on the surface. What is the proper procedure?
Answer: Wipe the area with a wet cloth, then disinfect with 70% isopropyl alcohol.
The proper cleaning procedure involves a two-step process: first cleaning, then disinfecting. The area should first be cleaned with a detergent or wet cloth to remove the visible soil (the dried syrup), and then disinfected with an appropriate agent like 70% isopropyl alcohol to kill any remaining microorganisms. The other options are either ineffective or inappropriate for a pharmacy setting.
- Before a filled prescription vial is presented to the pharmacist for final verification, what is a key contamination prevention step the technician must ensure?
Answer: The exterior of the vial and cap are clean and free of drug residue.
Ensuring the final prescription container is clean and free from any powder or residue is a critical quality and safety step. This prevents the patient or pharmacist from coming into contact with drug residue, which could cause a skin reaction or accidental ingestion, and it maintains a professional and clean appearance. The other options are part of the workflow but are not direct contamination prevention measures for the final product.
- While working in the pharmacy, a technician feels the need to sneeze. What is the most appropriate infection prevention action to take?
Answer: Step away from the work area, sneeze into the crook of their elbow, and perform hand hygiene.
Proper respiratory hygiene is crucial for preventing the spread of airborne droplets. The recommended procedure is to sneeze or cough into the crook of the elbow or a tissue. Sneezing into hands contaminates them directly. After any such event, it is imperative to perform hand hygiene before resuming work to prevent the spread of germs.
- According to CDC guidelines, what is the minimum amount of time a pharmacy technician should scrub their hands with soap and water to ensure effective hand hygiene?
Answer: 20 seconds
The Centers for Disease Control and Prevention (CDC) recommends scrubbing hands with soap and water for at least 20 seconds. This duration is necessary to effectively remove germs and prevent their spread. The other options represent insufficient time for proper handwashing.
- A pharmacy technician is asked to fill a prescription for methotrexate, a medication on the NIOSH list of hazardous drugs. What minimum personal protective equipment (PPE) is required for simply counting these tablets?
Answer: Two pairs of chemotherapy-rated gloves.
According to USP <800> standards for handling hazardous drugs (HDs), double gloving with chemotherapy-rated gloves is required for many activities, including counting and packaging certain HDs like methotrexate. This provides an extra layer of protection against accidental exposure from drug dust or residue. A single pair is insufficient, and other PPE might also be needed depending on the specific task.
- A pharmacy technician needs to perform hand hygiene after entering prescription data and before counting tablets. Their hands are not visibly soiled. Which method of hand hygiene is most appropriate in this situation?
Answer: Using an alcohol-based hand sanitizer.
When hands are not visibly dirty, an alcohol-based hand sanitizer with at least 60% alcohol is the preferred method for hand hygiene in healthcare settings because it is effective and efficient. Washing with soap and water is required when hands are visibly soiled. Wiping with a dry towel or rinsing with water alone is not effective for disinfection.
- To minimize the spread of infection, high-touch surfaces in the pharmacy, such as keyboards, mice, and phones, should be cleaned at least:
Answer: At the beginning of each shift or daily.
High-touch surfaces are common vectors for pathogen transmission. To effectively break the chain of infection, these surfaces should be cleaned and disinfected frequently, at least once daily or at the beginning of each shift, as part of a routine environmental cleaning schedule.
