A community health nurse is participating in a natural disaster drill. This activity would fall into which of the following phases of the disaster management cycle?

Disaster prevention

Disaster response

Disaster preparedness

Disaster recovery

Answer and Explanation

The Correct Answer is C

A. Disaster prevention: This phase focuses on measures taken to avoid the occurrence of a disaster or minimize its effects, such as reinforcing buildings or implementing early warning systems. Participating in a drill does not prevent a disaster but prepares for response.

B. Disaster response: The response phase involves actions taken during or immediately after a disaster to manage its effects, such as triage, evacuation, or providing emergency care. A drill does not simulate real-time emergency relief but rather anticipates and trains for it.

C. Disaster preparedness: Drills are part of disaster preparedness, which involves planning, training, and educating staff and community members to ensure effective response when a disaster occurs. It allows practice of roles and identification of gaps in emergency plans.

D. Disaster recovery: Recovery includes efforts to restore services, rebuild infrastructure, and support emotional healing after a disaster. Since drills occur before a disaster, they do not represent recovery but proactive planning instead.

Correct Answer is A

Explanation

A. Primary prevention: This strategy aims to prevent the onset of disease or injury before it occurs. By educating adolescents on the dangers of smoking, the nurse is promoting behaviors that reduce the risk of starting tobacco use, thereby preventing potential health issues like cancer or cardiovascular disease.

B. Tertiary prevention: This involves managing and reducing complications in individuals who already have a disease. The nurse is not treating or managing existing health issues related to smoking but is trying to prevent tobacco use entirely.

C. Screening: Screening identifies individuals who may have a disease or risk factor early on. No diagnostic or early detection efforts are involved in this educational session.

D. Case findings: Case finding involves actively identifying individuals with a specific condition, often through outreach or assessment. The nurse is not identifying smokers or tobacco-related illness in this scenario.

A. A client who has undergone radiation therapy within the last 3 years B. A client who has received the bacille Calmette-Guerin vaccine within the last 10 years C. A client who has acquired immune deficiency syndrome D. A client who has lived in a country where tuberculosis is endemic

Correct Answer is B

Explanation

A. A client who has undergone radiation therapy within the last 3 years: Radiation therapy may suppress the immune response, potentially leading to a false-negative rather than a false-positive Mantoux test due to reduced ability to mount a reaction.

B. A client who has received the bacille Calmette-Guerin vaccine within the last 10 years: The BCG vaccine can cause a false-positive Mantoux result because the vaccine uses a strain of Mycobacterium bovis, which can trigger a reaction similar to TB exposure in skin testing.

C. A client who has acquired immune deficiency syndrome: Clients with AIDS are immunocompromised, which increases the likelihood of a false-negative Mantoux result, as their immune systems may not respond sufficiently to the test.

D. A client who has lived in a country where tuberculosis is endemic: This client is at higher risk for true TB exposure, and a positive result is more likely to reflect actual infection rather than a false-positive reaction.
