Infection Control Flashcards

Blood-borne infections include

Answer: hepatitis

Hepatitis, particularly Hepatitis B and C, is a well-known blood-borne infection. These viruses are transmitted through contact with infected blood or other body fluids, such as during needle-stick injuries, unprotected sex, or from mother to child. The other options are typically spread through respiratory droplets or direct contact.

While Mr. Jones is visiting his wife, you notice that he is sneezing and blowing his nose. What is the best step?

Answer: Teach him proper hand washing.

In a healthcare setting, preventing the spread of infection is paramount. Since Mr. Jones is exhibiting symptoms of a respiratory illness, teaching him proper hand washing techniques is the most effective way to reduce the transmission of germs, protecting both his wife and other vulnerable individuals in the facility.

While emptying the trash in a client's room, you get stuck by a needle that should have been placed in the sharps container. What is the first thing to do?

Answer: Wash the site for several minutes.

In the event of a needle stick injury, the immediate first aid response is to thoroughly wash the affected area with soap and water for several minutes. This action helps to cleanse the wound and reduce the potential for infection. After this immediate step, the incident should be reported and medical evaluation sought.

Precautions for a patient in respiratory isolation include all EXCEPT

Answer: gown

Respiratory isolation precautions, such as for airborne or droplet-borne diseases, primarily focus on preventing the spread of pathogens through the air. This typically involves a private room, special air handling systems (for airborne), and the use of a mask. A gown is primarily used for contact precautions or when there is a risk of clothing contamination from body fluids, not typically a standard requirement solely for respiratory isolation.

When washing your hands, apply the soap

Answer: after wetting your hands.

When washing hands, it is essential to wet them first before applying soap. This allows the soap to lather effectively and spread evenly over the entire hand surface. Applying soap to dry hands can make it less effective at creating friction and lifting germs, reducing the overall efficacy of the handwashing process.

To prevent the spread of infection, how should the nurse aide handle the soiled linens removed from a client’s bed?

Answer: Put them in the dirty linen container.

Soiled linens are considered contaminated and can harbor various pathogens. To prevent the spread of infection, they must be immediately placed into a designated dirty linen container. This practice minimizes contact with contaminated materials, preventing microorganisms from transferring to other surfaces, staff, or clients.

After cleaning a resident's dentures, you remove and discard your gloves. What is the next step?

Answer: Wash your hands.

Even after removing gloves, there is always a risk of microscopic contamination from the gloves themselves or from contact with the soiled item. Handwashing is the single most effective way to remove any remaining pathogens and prevent their spread. This critical step ensures proper infection control and breaks the chain of infection after completing a task involving potential exposure to bodily fluids or contaminants.

At the start of a bed bath, Mrs. Smith takes washcloth to clean her perineal area and puts it back into the basin of water. The nurse aide should

Answer: clean the basin and replace the water.

The perineal area is considered contaminated, and using a washcloth there immediately contaminates the entire basin of water with potential pathogens. To prevent the spread of bacteria and ensure proper hygiene for the rest of the bath, the nurse aide must discard the contaminated water, clean the basin, and refill it with fresh, clean water. This maintains a clean environment and prevents cross-contamination during patient care.

During dinner, a client who is HIV-positive accidentally breaks a glass and cuts himself. What is the proper procedure?

Answer: Block off the area until it can be cleaned.

A broken glass with blood presents both a biohazard and a physical hazard. Blocking off the area immediately prevents others from stepping on glass or coming into contact with the blood, which is considered potentially infectious under standard precautions. This allows for a safe and controlled environment for proper cleanup using appropriate personal protective equipment (PPE) and disinfection protocols.

All body fluids are considered infectious EXCEPT

Answer: sweat

Under standard precautions, all body fluids are treated as potentially infectious for bloodborne pathogens, with the notable exception of sweat. While sweat can contain some microorganisms from the skin, it is not considered a vehicle for transmitting serious bloodborne diseases like HIV or Hepatitis B and C. Therefore, it is generally not classified as an infectious body fluid in the same way as blood, semen, or saliva (especially if blood is present).

Personal Protective Equipment (PPE) is used to

Answer: reduce exposure for health care workers.

Personal Protective Equipment (PPE), such as gloves, gowns, masks, and eye protection, creates a physical barrier between healthcare workers and infectious materials. Its primary purpose is to minimize the risk of exposure to pathogens, thereby protecting the wearer from acquiring infections. By reducing direct contact with contaminants, PPE plays a crucial role in ensuring the safety of healthcare personnel.

When wearing gloves, it is important to remember

Answer: gloves are worn when using disinfectants.

Disinfectants contain harsh chemicals that can irritate, damage, or cause allergic reactions to the skin. Wearing gloves provides a protective barrier, preventing direct skin contact with these potentially hazardous substances. This ensures the healthcare worker's hands are protected from chemical burns, dryness, or other adverse effects during cleaning and disinfection procedures.

Which conditions promotes the growth of bacteria?

Answer: dark, warm, moist

Bacteria are microorganisms that require specific environmental conditions to grow and reproduce effectively. They generally thrive in dark areas away from direct sunlight, warm temperatures similar to the human body, and moist environments which are essential for their metabolic processes. These conditions are commonly found in many healthcare settings, highlighting the importance of rigorous infection control.

It is important that a client's dressings remain

Answer: clean and dry.

Dressings serve to protect wounds from external contamination and promote an optimal healing environment. Keeping them clean prevents the introduction of new pathogens to the wound site, which could lead to infection. Maintaining dryness prevents moisture buildup that can macerate the skin, promote bacterial growth, and compromise the dressing's integrity, thus ensuring effective wound care and reducing infection risk.

When caring for a patient with MRSA, the nurse aide should wear

Answer: gown and gloves

MRSA (Methicillin-resistant Staphylococcus aureus) is a highly contagious bacteria often spread through direct contact with an infected person or contaminated surfaces. To prevent its transmission, healthcare workers must implement contact precautions, which specifically require wearing a gown and gloves when entering the patient's room or having direct contact with the patient or their environment. This barrier prevents the bacteria from contaminating the aide's clothing or hands.

The most important way to prevent the spread of infection is

Answer: Hand washing

Hand washing, or hand hygiene, is universally recognized as the single most effective and fundamental method to prevent the spread of infection in all settings, especially healthcare. It physically removes transient microorganisms from the hands, effectively breaking the chain of infection. While other measures like antibiotics and vaccinations are important, consistent and proper hand washing has the broadest impact on preventing pathogen transmission and saving lives.

Used disposable supplies and equipment should be discarded

Answer: in a designated receptacle.

Used disposable supplies and equipment are often contaminated with bodily fluids or pathogens and pose an infection risk. Discarding them in a designated receptacle, such as a biohazard bin or a sharps container, ensures they are handled safely and disposed of according to facility policies and regulations. This practice prevents accidental exposure to pathogens, minimizes environmental contamination, and maintains a clean, safe environment for everyone.

After Mr. Johnson’s bath, the nurse aide realizes she needs another towel to completely dry Mr. Johnson. The nurse aide should

Answer: ask a co-worker to bring a towel from the clean linen cart.

Leaving a client unattended, especially during a bath, can compromise their safety, privacy, and dignity. Asking a co-worker to retrieve a clean towel ensures the client remains safe and attended to, while also maintaining the sterility of the clean linen supply. This demonstrates good teamwork, adherence to patient safety protocols, and efficient workflow without compromising care.

Infection control practices that prevent the transmission of disease are called

Answer: standard precautions.

Standard precautions are a fundamental set of infection control practices applied to the care of all patients, regardless of their diagnosis or presumed infection status. They involve treating all blood, body fluids, non-intact skin, and mucous membranes as potentially infectious. These practices include essential measures like hand hygiene, use of personal protective equipment, safe injection practices, and safe handling of contaminated equipment or surfaces to prevent disease transmission.
