ATI Community Health Proctored Exam 2026

Home Environmental Safety:

1. A home health nurse performs a home safety evaluation. Which findings require action? (Select all that apply.)

• A. The water heater is set at 54.4°C (130°F).
• B. An extension cord extends across the floor of the living room.
• C. The living room floor is carpeted.
• D. Rubber-backed mats are placed at the entryways.

Answer: A and B. Water heaters must be set below 120°F (49°C) to prevent scalding burns, and unsecured cords across walkways present a severe tripping hazard. Carpet and rubber-backed mats actually increase traction and decrease falls, so they aren't hazards.

Program Planning:

2. A nurse is developing a health-screening program for clients at risk for hypertension. Which action should the nurse take first?

• A. Secure funding for blood pressure equipment.
• B. Conduct a survey to identify the community's need for hypertension screening.
• C. Recruit volunteer nurses for the screening event.
• D. Advertise the screening program to the community.

Answer: B. According to the nursing process, assessment is the primary step. The nurse must assess population needs before designing interventions or securing funding.

Epidemiology Calculations:

3. 3,144 new cases of chlamydia occurred in a population of 325,986 over one year. What is the annual incidence rate?

• A. About 1 reported case per 1,000 population.
• B. About 10 reported cases per 1,000 population.
• C. About 100 reported cases per 1,000 population.
• D. About 32 reported cases per 1,000 population.

Answer: B. (3,144 ÷ 325,986) × 1,000 = 9.64 ≈ 10 cases per 1,000 residents.

Epidemiological Triangle:

4. In a mumps outbreak among school children, which element is the host?

• A. The mumps virus.
• B. The school facility.
• C. The children.
• D. The school nurse.

Answer: C. Host = the susceptible human/organism (the children). Agent = the mumps virus. Environment = the school facility.

Levels of Prevention:

5. Which action is an example of a secondary prevention activity?

• A. Administering a childhood vaccination.
• B. Genetic testing for cystic fibrosis.
• C. Teaching bicycle helmet safety.
• D. Providing physical therapy after a stroke.

Answer: B. Genetic screening/testing detects disease state or carrier status early in asymptomatic individuals — that's secondary prevention. Vaccinations and helmet education are primary prevention; post-stroke rehab is tertiary.

Nationally Notifiable Conditions:

6. Which of the following client findings require national notification?

• A. Elevated blood lead level (12 mcg/dL).
• B. Active tuberculosis (positive PPD >10mm + hemoptysis).
• C. Strep throat.
• D. Shingles.

Answer: A and B. Active TB and elevated blood lead levels are nationally reportable conditions. Strep throat and shingles do not require CDC notification.

Ethical Dilemmas:

7. In a homeless shelter during a pandemic, which situation represents a true ethical dilemma?

• A. Determining the arrangement of residents within limited space to prevent infection while refusing admission to unsheltered individuals.
• B. Deciding whether to document a resident's vital signs before or after meals.
• C. Choosing which brand of hand sanitizer to stock.
• D. Assigning staff to different shifts based on availability.

Answer: A. A true ethical dilemma exists when two compelling ethical principles conflict — here, public health protection via bed-density limits versus the duty to shelter vulnerable individuals.
