NCAS Infection Control and Prevention

Question 1

Which level of precautions is used for ALL patients regardless of suspected or confirmed infection status in US health care settings?

Accepted Answer

Standard Precautions

Answer

Standard Precautions apply to every patient interaction in all health care settings, treating all blood, body fluids, and non-intact skin as potentially infectious.

Question 2

A patient is diagnosed with active pulmonary tuberculosis. Which type of transmission-based precautions should the community nurse recommend?

Accepted Answer

Airborne Precautions with negative pressure room and N95 respirator

Answer

Active TB requires Airborne Precautions including a negative pressure isolation room and an N95 respirator because TB bacilli travel on small airborne particles.

Question 3

The community health nurse is teaching proper hand hygiene. According to CDC guidelines, which situation requires handwashing with soap and water rather than alcohol-based hand rub?

Accepted Answer

When hands are visibly soiled or after contact with a patient with Clostridioides difficile (C. diff)

Answer

Soap and water are required for visibly soiled hands and after caring for C. diff patients, as alcohol-based hand rubs are ineffective against C. diff spores.

Question 4

Which vaccine-preventable disease is characterized by a prodrome of Koplik's spots followed by a maculopapular rash spreading from head to trunk?

Accepted Answer

Measles (rubeola)

Answer

Koplik's spots (bluish-white spots on the buccal mucosa) followed by a cephalocaudal maculopapular rash are classic presentations of measles.

Question 5

A community nurse is managing a norovirus outbreak at a long-term care facility. Which action is MOST important to contain spread?

Accepted Answer

Cohort ill residents, implement Contact Precautions, enforce hand hygiene with soap and water

Answer

Norovirus outbreaks in congregate settings require cohorting ill persons, Contact Precautions, and soap-and-water handwashing because alcohol hand rub is less effective against norovirus.
