Correct Answer: B

Rationale: In the management of acute respiratory infection in a child, it is essential to address various aspects of care. Providing safe remedies to relieve symptoms like sore throat and cough (Choice A) helps in managing discomfort. Advising the mother to monitor for signs of pneumonia (Choice C) is crucial for early detection and intervention if complications arise. Ensuring proper nutrition (Choice D) is important for the child's overall health and immune function during illness. Therefore, all the listed interventions are appropriate in managing acute respiratory infection, making Choice B the correct answer. Choices A, C, and D are incorrect on their own as they address only specific aspects of care and not the comprehensive management of acute respiratory infection.

Correct Answer: A

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

Correct Answer: D

Rationale: A decrease in chest wall expansion suggests that the client may be experiencing a serious complication, such as worsening pneumonia or respiratory failure, requiring immediate medical attention. This finding indicates a potential decrease in lung function, which could lead to respiratory distress. Pleuritic pain on inspiration may be related to the disease process but does not indicate an immediate need for intervention. Dry mucus membranes in the mouth may require attention but are not as critical as a decrease in chest wall expansion. A decrease in respiratory rate could be concerning but is not as urgent as a decrease in chest wall expansion, which directly impacts respiratory function.

Correct Answer: D

Rationale: The correct answer is D: greater use of contraception among teens. This outcome indicates successful prevention of pregnancies by demonstrating that teens are taking proactive steps to avoid unintended pregnancies. Increased attendance at health education classes (choice A) may show improved knowledge but does not directly measure the prevention of pregnancies. While a decreased number of repeat pregnancies among teens (choice B) is positive, it does not necessarily indicate prevention of initial pregnancies. A higher number of teens seeking prenatal care (choice C) is important for maternal and fetal health but does not directly reflect the prevention of teen pregnancies.

Correct Answer: B

Rationale: The correct answer is B: Primary health care. Primary health care is the initial point of contact between community members and the healthcare system. This level of care focuses on preventive and primary treatment services. Choices A, C, and D are incorrect because secondary, tertiary, and intermediate care levels are more specialized and are usually accessed after primary care, depending on the complexity of the health issue.
