Correct Answer: B

Rationale: The correct answer is B: 'Statistics'. Statistics is the systematic approach of obtaining, organizing, and analyzing numerical facts to draw conclusions. Vital statistics, morbidity, and mortality are more specific terms within the field of statistics. Vital statistics focus on births, deaths, marriages, and divorces. Morbidity refers to the incidence of illness or disease in a population. Mortality specifically deals with deaths in a population. Hence, B is the most comprehensive and fitting choice for the definition provided.

Correct Answer: B

Rationale: To succeed as a change agent, being an information seeker is crucial. While being an information provider, motivator, and leader are important roles, actively seeking information is fundamental to understanding the community's needs, concerns, and challenges before implementing effective changes. This active information seeking helps in making informed decisions and developing strategies that address the specific issues faced by the community. Therefore, the correct choice is B. Choices A, C, and D are also important roles but may not be as fundamental as actively seeking information.

Correct Answer: A

Rationale: High protein levels in the cerebrospinal fluid are indicative of bacterial meningitis, as the presence of bacteria in the CSF leads to increased protein production. Elevated protein levels can be seen in inflammatory conditions like meningitis. Choice B, clear color, is not expected in meningitis as it is typically associated with cloudy or turbid CSF. Elevated sed rate (choice C) and increased glucose (choice D) are not typically associated with the laboratory findings seen in meningitis.

Correct Answer: D

Rationale: Observing swallowing patterns is crucial post-tonsillectomy and adenoidectomy to detect signs of bleeding. Offering ice chips instead of ice cream helps prevent throat irritation. Placing the child in a semi-Fowler's position promotes airway patency and reduces the risk of aspiration. Encouraging the child to drink from a cup instead of a straw minimizes the risk of dislodging the surgical site.

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.
