Correct Answer: A

Rationale: The correct answer is A: Primary prevention. Primary prevention focuses on preventing the development of diseases or injuries before they occur by promoting healthy behaviors and lifestyles. In this scenario, the health program targeting lifestyle modifications to reduce chronic diseases aligns with primary prevention efforts. Choice B, secondary prevention, involves early detection and treatment to prevent the progression of disease. Choice C, tertiary prevention, focuses on managing and treating existing diseases to prevent complications. Choice D, quaternary prevention, relates to actions taken to mitigate or avoid the consequences of unnecessary or excessive interventions in healthcare.

Correct Answer: B

Rationale: The correct answer is to assess the child's asthma management plan. This is the priority action as it allows the nurse to evaluate the current treatment regimen, identify any gaps or areas for improvement, and ensure that the plan is being effectively implemented. Teaching the child how to use an inhaler (Choice A) may be important but should come after assessing the management plan. Discussing the importance of school attendance with the parents (Choice C) is secondary to ensuring proper asthma management. Referring the child to a pulmonologist (Choice D) may be necessary but is not the priority at this stage; first, the nurse needs to evaluate the current plan in place.

Correct Answer: D

Rationale: The correct answer is D - 'overcrowding and its effect.' While overcrowding is an important topic, it will be given least priority compared to the other choices when conducting health education sessions for a group of mothers. Proper selection and preparation of food (Choice A) is crucial for ensuring adequate nutrition, handwashing before preparing food (Choice B) is essential for preventing foodborne illnesses, and cutting children's fingernails short (Choice C) is important for maintaining good hygiene. Overcrowding, although significant in the context of public health, might be considered less immediately relevant for a group of mothers in a health education session focused on more direct and practical aspects of family health and hygiene.

Correct Answer: B

Rationale: Integrative models of human health consider health factors as intertwined and interactive, involving various components like physical, psychological, and social aspects. This holistic approach recognizes that health is influenced by a combination of factors, not just physical phenomena (choice A). While psychosocial problems can impact health, integrative models go beyond attributing health solely to psychosocial issues (choice C). Additionally, integrative models do not imply that health is effective only when combined with alternative therapies (choice D), but rather emphasize the interconnectedness of various health components.

Correct Answer: B

Rationale: The correct answer is B: Hepatitis B. The Hepatitis B vaccine is crucial for pregnant women as it helps prevent transmission of the virus to the baby during childbirth. Measles-mumps-rubella vaccine (choice A) is not directly related to the current situation of the client being pregnant. Human papillomavirus vaccine (choice C) is recommended for adolescents but is not specifically indicated in this case. Pneumococcal vaccine (choice D) is not a priority in this scenario compared to Hepatitis B, which is crucial for preventing vertical transmission.
