Isolation of a child with measles belongs to what level of prevention?

Correct Answer: B

Rationale: The correct answer is B: Secondary prevention. Isolating a child with measles falls under secondary prevention because it aims to detect and treat the disease early to prevent its spread to others. Secondary prevention focuses on early detection, prompt treatment, and minimizing the impact of the disease. Isolation helps prevent the transmission of measles to unvaccinated individuals. A: Primary prevention aims to prevent the disease from occurring in the first place, such as vaccination against measles. C: Intermediate prevention is not a widely recognized level of prevention. D: Tertiary prevention focuses on managing the long-term effects of a disease and preventing complications, which is not applicable in this scenario.

Correct Answer: B

Rationale: The correct answer is B because a home visit enables the nurse to observe the living conditions, family dynamics, and environmental factors that can impact the patient's health. This firsthand appraisal helps in tailoring care plans to better suit the patient's needs. Choice A is incorrect as home visits usually limit the number of patients seen due to travel time. Choice C is incorrect because sharing experiences is not the primary purpose of a home visit. Choice D is incorrect as the main focus is on assessing the patient's home environment, not on developing the family's initiative in health provision.

Correct Answer: B

Rationale: The correct answer is B: "Should minimize if not totally prevent the spread of infection." The bag technique is crucial in maintaining asepsis during home visits. By ensuring that the items in the bag are sterile and using proper techniques to prevent contamination, the spread of infection can be minimized or prevented. This is essential to protect both the patient and the nurse. The other choices are incorrect because saving time and effort (A) should not compromise infection control, overshadowing concern for the patient and family (C) is not related to infection prevention, and using different techniques depending on the situation (D) may lead to inconsistent infection control practices.

Correct Answer: B

Rationale: The correct answer is B: Analytical. In this situation, the nurse is conducting a study to analyze the factors contributing to the high mortality rate due to heart diseases. Analytical epidemiology focuses on investigating the causes and risk factors associated with diseases, which aligns with the nurse's study. Descriptive epidemiology primarily involves summarizing the characteristics of a disease outbreak or health condition, not analyzing contributing factors. Therapeutic epidemiology focuses on treatment interventions, which is not the case here. Evaluation epidemiology involves assessing the effectiveness of health programs, not specifically studying the causes of a disease.

Correct Answer: A

Rationale: Rationale: A is correct because conducting assessments helps in early detection and containment of communicable diseases. It is crucial for epidemiologic surveillance. B is incorrect as it focuses on investigation, not nursing role. C is about health promotion, not directly related to epidemiologic function. D is an incomplete choice.
