Correct Answer: B

Rationale: The correct answer is B - 'All of these.' The Magna Carta of Public Health Workers aims to achieve multiple objectives, including developing the skills and capabilities of health workers to deliver health projects/programs, encouraging those with proper qualifications to remain in government service, and promoting the social and economic well-being of health workers. Choice A, C, and D are all part of the comprehensive goals outlined in the Magna Carta for Public Health Workers.

Correct Answer: A

Rationale: The correct answer is A: Primary prevention. Administering a booster dose of DTaP vaccine to an infant is an example of primary prevention. Primary prevention aims to prevent disease or injury before it occurs by preventing exposure to risk factors. Tertiary prevention focuses on reducing the impact of a disease or injury that has already occurred, while secondary prevention involves early detection and treatment to prevent the progression of disease. Choice B, tertiary prevention, is incorrect as it deals with managing the consequences of a disease rather than preventing it. Choice C, secondary prevention, is also incorrect as it focuses on early detection and treatment rather than vaccination to prevent the disease. Choice D, primary nursing, is unrelated to the level of prevention being implemented in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Preventing the onset of disease. Health promotion activities aim to prevent illnesses and promote overall well-being through education, lifestyle changes, and preventive measures. Choice A is incorrect as health promotion is not primarily about treating existing health conditions but rather preventing them. Choice C is incorrect because palliative care focuses on providing relief and comfort to patients with serious illnesses, not on preventing diseases. Choice D is also incorrect as conducting clinical trials is a research activity to test new treatments or interventions, not a focus of health promotion.

Correct Answer: D

Rationale: The correct answer is D: 4 to 6 years of age. The CDC recommends the MMR booster for children in this age group. Choice A (13 to 18 years of age) is incorrect as it is not the recommended age range for the MMR booster. Choice B (11 to 12 years of age) is also incorrect as it does not align with the CDC guidelines for the MMR booster. Choice C (18 to 24 months of age) is not the correct age range for the MMR booster according to CDC recommendations.

Correct Answer: D

Rationale: When determining the priority health problem within a family, one key criterion to consider is the modifiability of the problem. This means assessing whether the health issue can be changed or improved through interventions. Choices A, B, and C are not directly related to the priority of the health problem within the family. The expected consequence of the problem, cooperation and support of the family, and involvement of family members are important factors but do not specifically address the priority of the health issue based on modifiability.
