Correct Answer: A

Rationale: The correct information the nurse should provide is that anthrax infection occurs when spores enter a host. Choice B is incorrect as mature anthrax bacteria do not live dormant on inanimate objects. Choice C is incorrect as anthrax spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.

Correct Answer: C

Rationale: The correct answer is C. A CD4 count less than 200 cells/mm³ is a diagnostic criterion for AIDS. Choices A, B, and D are incorrect. Choice A is vague and does not reflect the diagnostic criteria for AIDS. Choice B is not accurate, as the presence of opportunistic infections, not their absence, is indicative of AIDS. Choice D is unrelated to the diagnosis of AIDS in adults.

Correct Answer: A

Rationale: A community hospital is categorized under secondary level health care. Secondary level health care facilities, like community hospitals, provide specialized outpatient care, diagnostic services, and treatment that are more complex than what is offered in primary health care settings. Choice B, primary health care, refers to basic and routine health care services typically provided by family doctors or general practitioners, which is not the level of care provided by community hospitals. Tertiary level care (choice C) involves highly specialized and complex medical services such as neurosurgery or organ transplants, which are beyond the scope of services provided by community hospitals. Intermediate level care (choice D) is not a recognized category in the hierarchy of health care levels.

Correct Answer: D

Rationale: The correct answer is D: Elevated creatinine phosphokinase (CPK). Elevated CPK levels indicate muscle damage, including damage to the cardiac muscle, which aligns with the diagnosis of myocardial infarction. Choice A, low serum albumin, is not directly related to myocardial infarction. Choice B, high serum cholesterol, is more associated with conditions like atherosclerosis rather than acute myocardial infarction. Choice C, abnormally low white blood cell count, is typically not a lab value associated with myocardial infarction; instead, it could suggest other conditions like infections or bone marrow issues.

Correct Answer: A

Rationale: The correct first step for thermal protection of a newborn is to dry the baby thoroughly immediately after birth. This helps prevent heat loss and is crucial in maintaining the baby's body temperature. Choice B, covering the baby with a clean, dry cloth after the cord has been cut, is not the initial step as drying the baby comes first. Choice C, drying the baby thoroughly after the cord has been cut, is also not the first step. Choice D, covering the baby with a clean, dry cloth immediately after birth, is not as effective as drying the baby to prevent heat loss.
