Safety Flashcards

A cleanser similar to an iodophor can be used to disinfect surfaces. What classification is this?

Answer: Intermediate level.

Although they are not suitable for sterilization, iodophor-type cleansers can be beneficial as surface disinfectants. It is advised to pre-clean units in order to lower the operatory's bioburden levels. Although this step is frequently skipped in an attempt to save time, it is crucial for office infection control procedures.

What should the employer do for the exposed employee when they receive a report of an exposure occurrence at the dentist office?

Answer: An employee should receive a private medical evaluation from the company, along with a follow-up visit from a licensed medical professional.

The bloodborne pathogens requirement states that an employer must send a qualified physician to do a private medical evaluation and follow-up for an exposed employee after receiving a report of an exposure incidence at a dental clinic. This involves giving the exposed person blood tests to find out if they have HIV or hepatitis B. It is necessary to record the exposure route as well as the conditions surrounding the exposure incidence.

The following are all instances of mechanical instrument cleaning, with the exception of:

Answer: glutaraldehyde solution.

When cleaning contaminated equipment mechanically, contact of some kind with the surface being scrubbed clean is implied. Holding solutions, often known as glutaraldehyde (""cold sterile"") solutions, function without making direct or abrasive contact with the surface. The only appropriate kind of apparatus for hand cleaning is a long-handled brush; nonetheless, because of the possibility of puncture injuries, this is the least preferred approach.

How many air exchanges per hour should a room with allogenic hematopoietic stem cell transplantation (HSCT) recipients have?

Answer: 12

Allogenic hematopoietic stem cell transplant recipients must to be kept in rooms with a minimum of 12 air exchanges per hour or point-of-service HEPA filtration with a 99.97% efficiency level that can eliminate particles with a size of at least 3 mcm. Although periodic environmental sampling is not necessary, air quality should be monitored since patients are particularly vulnerable to Aspergillus-related diseases. It is imperative to maintain aseptic technique and provide visitors with instruction on hand hygiene and basic precautions.

The longest period of infusion that a parenteral lipid bag can run is as follows due to the higher risk of infection associated with parenteral nutrition:

Answer: Six hours.

Parenteral lipid emulsions are highly susceptible to microbial growth because they provide an excellent culture medium for bacteria. Limiting the infusion time to six hours significantly reduces the risk of bacterial proliferation within the solution. This strict time limit is a critical infection prevention measure to minimize the chance of bloodstream infections associated with parenteral nutrition, ensuring patient safety.

The most efficient way to manage hospital-acquired infections is as follows:

Answer: cleaning one's hands.

Hand hygiene is universally recognized as the single most effective measure to prevent the spread of hospital-acquired infections (HAIs). Healthcare workers' hands are a primary vehicle for transmitting pathogens between patients and surfaces. Consistent and proper hand cleaning breaks the chain of infection, significantly reducing the incidence of HAIs and protecting patients.

The most common reason why mastitis occurs in nursing mothers is:

Answer: baby that had Staphylococcus aureus colonization.

Mastitis, an inflammation of the breast, is most commonly caused by bacterial infection, with Staphylococcus aureus being the predominant pathogen. This bacterium is often carried in the baby's nose or throat and can be transferred to the mother's breast during feeding, entering through cracked nipples or milk ducts. Therefore, the baby's colonization with S. aureus is a primary risk factor for the mother developing mastitis.

A German Shepherd that serves as a service animal for a crippled patient demands to be allowed to remain in the hospital room in order to help the patient. In conjunction with risk management, the appropriate response is to:

Answer: Make plans to accommodate the animal.

Under the Americans with Disabilities Act (ADA), service animals are generally permitted in hospitals and other public places to assist individuals with disabilities. Hospitals must make reasonable accommodations for service animals unless their presence poses a direct threat or fundamental alteration to the facility's operations. Therefore, the appropriate response is to collaborate with risk management to develop a plan that safely accommodates the service animal while adhering to infection control guidelines.

The nurse and the patient are talking about Rocky Mountain spotted fever, or Rickettsia rickettsii. Which of the patient's statements to the nurse demonstrates knowledge of the disease's route of transmission?

Answer: I'm going to wear insect repellent when camping.

Rocky Mountain spotted fever (RMSF), caused by Rickettsia rickettsii, is transmitted to humans through the bite of infected ticks. Therefore, the most effective way to prevent this disease is to avoid tick bites. Wearing insect repellent, especially one containing DEET or permethrin, is a crucial preventive measure when spending time in tick-infested areas like during camping, demonstrating knowledge of the disease's transmission route.

A group of preschool employees is attending an instructional session led by the nurse. The group is reminded by the nurse of the most crucial action to do in order to stop the infection from spreading. Which details did the nurse give the preschool staff?

Answer: After every interaction with a child, wash their hands.

In a preschool environment, children frequently touch shared surfaces and interact closely, making hand hygiene the most critical measure to prevent the spread of infections. Regular handwashing by staff, especially after every interaction with a child, significantly reduces the transmission of germs. This practice is more impactful than other options for direct infection prevention in this setting.

A patient with pneumonia is being cared for by the nurse during orientation, along with a new nurse. Which of the new nurse's statements best demonstrates that she understands this condition?

Answer: Pneumonia is an infectious disease that may not be dangerous to other people.

While pneumonia is an infectious disease, its transmissibility varies depending on the underlying cause (e.g., bacterial, viral, fungal). Many forms of pneumonia, especially bacterial pneumonia, are not highly contagious through casual contact and do not typically require strict isolation measures like negative pressure rooms. The statement correctly acknowledges its infectious nature but implies it's not always a high-risk threat for widespread transmission to others, demonstrating understanding of its varying contagiousness.
