CNA Safety and Infection Control 3

Question 1

An 88-year-old resident with dementia suddenly becomes more confused, refuses to eat, and has a new onset of urinary incontinence. They do not have a fever. What is the most likely cause for these changes that the CNA should report immediately?

Accepted Answer

An atypical presentation of an infection.

Answer

Older adults, especially those with cognitive impairments, often do not exhibit classic signs of infection like fever. Instead, infections can manifest as a sudden change in mental status (confusion), a decline in function (incontinence), or behavioral changes like loss of appetite. These subtle signs should be considered potential indicators of an underlying infection, such as a UTI or pneumonia, and require immediate reporting for further evaluation.

Question 2

You are providing care for a resident with a Clostridioides difficile (C. diff) infection. Which of the following cleaning and disinfection practices is most critical for preventing the spread of C. diff spores?

Accepted Answer

Cleaning the commode and high-touch surfaces with a bleach-based or other EPA-approved sporicidal disinfectant.

Answer

C. difficile forms spores that are resistant to standard disinfectants and alcohol-based hand sanitizers. Effective environmental cleaning requires the use of a sporicidal agent, such as a bleach solution or an EPA List K registered product, to kill the spores on surfaces and equipment. While hand washing with soap and water is crucial for hand hygiene, environmental disinfection requires a specific type of chemical agent.

Question 3

A resident is receiving internal radiation therapy (brachytherapy) with a temporary implant. Which safety principle is the highest priority for the CNA entering the room to provide brief, essential care?

Accepted Answer

Maximizing the distance from the resident whenever possible.

Answer

The core principles of radiation safety are time, distance, and shielding. For a CNA providing care to a patient with an internal radiation source, maintaining the greatest distance possible from the radioactive source (the resident) is a key strategy to minimize radiation exposure. While minimizing time in the room and using shielding (like lead aprons, if required by facility policy) are also important, maximizing distance is a fundamental and effective protective measure.

Question 4

During a facility-wide evacuation drill, what is the CNA's primary responsibility after ensuring the immediate safety of their assigned residents?

Accepted Answer

Contacting residents' family members to update them on the situation.

Answer

In an evacuation, a CNA's primary role is resident safety. This includes moving them to a safe location and then accounting for every resident they were assigned to. Reporting to the command center or designated assembly point and confirming that all assigned residents are present and safe is a critical step in the facility's overall emergency response plan.

Question 5

You discover a small, contained chemical spill from a cleaning agent in the utility room. After alerting your supervisor, what is the most appropriate first step according to standard safety protocols?

Accepted Answer

Consult the Safety Data Sheet (SDS) for the specific chemical.

Answer

Before taking any action to clean a chemical spill, it is essential to consult the Safety Data Sheet (SDS). The SDS provides critical information about the chemical's hazards, required personal protective equipment (PPE), and specific procedures for safe cleanup and disposal. Acting without this information could lead to injury or an improper response.
