Sample questions from Community Health RN 2026 Study Guide

This material has 24 questions with answers and rationales. Here are the first 5.

1. 1.A community nurse organizes a fall-prevention exercise class for older adults who have not fallen and have no related injury. Which prevention level best describes the program?

   • A.B. Secondary prevention
   • B.D. Diagnostic case finding
   • C.A. Primary prevention
   • D.C. Tertiary prevention

   Rationale: A is correct because the program aims to prevent an initial injury. B involves early detection of an existing problem. C reduces disability or complications after an established condition. D identifies possible existing disease and does not describe this exercise program.

2. 2.During a one-week outbreak, 30 of 150 residents who attended a shared meal develop the defined illness. What is the attack rate among meal attendees?

   • A.B. 20%
   • B.D. 50%
   • C.C. 30%
   • D.A. 5%

   Rationale: B is correct: 30 divided by 150, multiplied by 100, equals 20%. A, C, and D do not result from the correct numerator and denominator. The denominator is the defined at-risk group of attendees, not the entire town.

3. 3.A nurse observes damaged sidewalks and few grocery stores during a windshield survey. Which action best strengthens the assessment?

   • A.D. Begin a program without consulting the community
   • B.C. Compare observations with resident interviews and local health data
   • C.A. Diagnose malnutrition in all neighborhood residents
   • D.B. Conclude that residents do not value exercise

   Rationale: C is correct because assessment should integrate observation, community perspectives, and quantitative data. A assigns an unsupported diagnosis. B makes a value judgment unsupported by observation. D excludes residents and risks selecting an intervention that does not match their priorities or actual needs.

4. 4.A client at a community clinic reports a persistent cough, night sweats, and weight loss. The nurse suspects pulmonary tuberculosis. What is the best initial action?

   • A.B. Begin routine nutrition counseling
   • B.A. Leave the client in the waiting area until test results return
   • C.C. Explain that a skin test will determine contagiousness immediately
   • D.D. Provide source control as tolerated, separate the client, and arrange prompt evaluation with appropriate precautions

   Answer and rationale are in the full material.

5. 5.An asymptomatic client has a positive interferon-gamma release assay. Which explanation by the nurse is most accurate?

   • A.A. 'Additional evaluation is needed to determine whether you have latent infection or active tuberculosis disease.'
   • B.C. 'This result proves that your lungs contain active tuberculosis disease.'
   • C.D. 'Because you have no symptoms, no further evaluation is needed.'
   • D.B. 'You are definitely contagious until this test becomes negative.'
