Practice Pack 2026 |Questions |Answers |Rationales
1. A community health nurse is planning a primary prevention strategy for
communicable diseases. Which of the following activities should the nurse
include?
A. Providing tuberculin skin testing for at-risk employees
B. Leading a support group for clients living with HIV
C. Administering a measles, mumps, and rubella (MMR) vaccine to a preschooler
D. Teaching a client with chlamydia about the importance of partner notification
Answer: C

Which level of prevention is the nurse performing?
A. Primary prevention
B. Quaternary prevention
C. Tertiary prevention
D. Secondary prevention
