LVN Infection Control & Safety Practices — Questions and Answers
Question 1: What is the primary goal of infection control in healthcare settings?
- To increase hospital stay duration.
- To enhance medication effectiveness.
- To prevent the spread of infections (Correct answer)
- To reduce staff workload.
Correct answer: To prevent the spread of infections
The primary goal of infection control in healthcare settings is to prevent the transmission of infectious agents among patients, staff, and visitors. By implementing various strategies like hand hygiene and PPE, healthcare facilities aim to minimize healthcare-associated infections (HAIs) and ensure a safe environment.
Question 2: Which of the following is considered a standard precaution?
- Using hand sanitizer before eating.
- Wearing gloves when touching blood or bodily fluids (Correct answer)
- Avoiding contact with coworkers.
- Covering windows with curtains.
Correct answer: Wearing gloves when touching blood or bodily fluids
Wearing gloves when touching blood, bodily fluids, non-intact skin, or contaminated items is a fundamental component of standard precautions. This practice creates a barrier to prevent the transmission of microorganisms and protect healthcare workers from exposure to potential pathogens.
Question 3: When should hand hygiene be performed?
- Only after patient contact.
- Only when wearing gloves.
- Before and after patient contact (Correct answer)
- Once per shift.
Correct answer: Before and after patient contact
Hand hygiene, including handwashing or using alcohol-based hand rub, must be performed before and after every patient contact. This critical practice prevents the transfer of microorganisms to and from patients, significantly reducing the risk of healthcare-associated infections.
Question 4: What is the correct way to dispose of a used needle?
- Recap it and throw in the trash.
- Place it in a sharps container without recapping (Correct answer)
- Leave it on the bedside table.
- Give it to another nurse.
Correct answer: Place it in a sharps container without recapping
Used needles must be immediately placed in a puncture-resistant sharps container without recapping. Recapping needles increases the risk of needlestick injuries, which can transmit bloodborne pathogens to healthcare workers.
Question 5: Which PPE is typically required for airborne precautions?
- Gown only.
- Surgical mask.
- N95 respirator (Correct answer)
- Face shield only.
Correct answer: N95 respirator
An N95 respirator is typically required for airborne precautions because it filters out at least 95% of airborne particles, including tiny droplet nuclei that can remain suspended in the air for extended periods. This specialized mask protects healthcare workers from inhaling infectious agents like tuberculosis or measles.
Question 6: What is the purpose of isolation precautions?
- To increase patient comfort.
- To avoid unnecessary documentation.
- To prevent disease transmission (Correct answer)
- To reduce medication errors.
Correct answer: To prevent disease transmission
The purpose of isolation precautions is to prevent the spread of infectious diseases from an infected or colonized patient to other patients, healthcare workers, and visitors. These precautions involve specific measures like PPE and dedicated equipment to break the chain of infection.
Question 7: Which of the following can reduce the risk of healthcare-associated infections (HAIs)?
- Using hand cream regularly.
- Wearing jewelry while caring for patients.
- Maintaining hand hygiene (Correct answer)
- Working double shifts.
Correct answer: Maintaining hand hygiene
Maintaining rigorous hand hygiene is the single most effective measure to reduce the risk of healthcare-associated infections (HAIs). Consistent handwashing or use of alcohol-based hand rub removes transient pathogens, preventing their spread between patients and surfaces.
Question 8: Which practice is essential when cleaning spills of blood or body fluids?
- Use a dry mop.
- Cover with paper towels and ignore it.
- Clean with appropriate disinfectant (Correct answer)
- Notify the patient only.
Correct answer: Clean with appropriate disinfectant
When cleaning spills of blood or body fluids, it is essential to use an appropriate disinfectant to effectively kill pathogens and decontaminate the area. This practice is crucial for infection control, preventing the spread of bloodborne pathogens and maintaining a safe environment.
Question 9: Which of the following best describes contact precautions?
- Wearing a face shield only.
- Using gloves and gown when in contact with patient or environment (Correct answer)
- Using a mask only when patient coughs.
- Avoiding patient contact completely.
Correct answer: Using gloves and gown when in contact with patient or environment
Contact precautions involve using gloves and a gown when entering the patient's room or coming into contact with the patient or their environment. These precautions are implemented for infections that can be transmitted by direct or indirect contact, such as MRSA or C. difficile.
