Correct Answer: B

Rationale: Under the present system, the local government unit is responsible for all the listed activities. This includes the operation and maintenance of health facilities, implementation of health programs/projects, and delivery of health services. Therefore, choice B, 'All of these activities,' is the correct answer. Choices A, C, and D are incorrect because they are all responsibilities that fall under the local government unit's jurisdiction as well.

Correct Answer: D

Rationale: The client's symptoms of shortness of breath, headache, dizziness, and nausea are indicative of carbon monoxide poisoning, which can result from exposure to gasoline-powered equipment like pressure washers. Asbestos (Choice A) exposure would typically present with respiratory issues and cancer but not the rapid onset of symptoms described. Silica dust (Choice B) exposure is associated with respiratory conditions like silicosis, not the multisystem symptoms in the scenario. Histoplasmosis (Choice C) is a fungal infection that primarily affects the lungs and is not related to the client's exposure to a gasoline-powered pressure washer.

Correct Answer: A

Rationale: The correct answer is A, maternal mortality. Maternal mortality specifically measures the risk of dying from pregnancy-related causes. Neonatal death rate, fetal death rate, and infant mortality rate focus on different populations and timeframes. Neonatal death rate refers to deaths within the first 28 days of life, fetal death rate measures stillbirths, and infant mortality rate includes deaths of infants under one year of age. Therefore, A is the most appropriate measure for assessing the risk of dying from causes related to pregnancy, childbirth, and puerperium.

Correct Answer: D

Rationale: The correct answer is D: Foods rich in vitamin K. Foods rich in vitamin K can interfere with the effectiveness of Coumadin (warfarin) by promoting blood clotting. It is crucial for clients on this medication to maintain a consistent intake of vitamin K and avoid sudden dietary changes. Choices A, B, and C are incorrect as they are not directly related to the interaction of Coumadin (warfarin) with vitamin K. Large indoor gatherings, exposure to sunlight, and active physical exercise do not have a significant impact on the effectiveness of Coumadin (warfarin) in comparison to the interaction with foods rich in vitamin K.

Correct Answer: A

Rationale: Administering analgesics on a fixed schedule is the most appropriate pain management strategy for a client with terminal cancer experiencing severe pain. This approach ensures consistent pain control and helps prevent breakthrough pain. Administering analgesics only when the client requests (Choice B) may lead to uncontrolled pain as the client may delay requesting medication until the pain becomes unbearable. Using non-pharmacological methods only (Choice C) may not provide adequate pain relief for a client experiencing severe pain. Increasing the dose of analgesics when the client complains of pain (Choice D) may result in inconsistent pain control and could lead to potential overdose or adverse effects.
