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: B

Rationale: Obtaining a peripheral O2 saturation reading is the priority intervention in this scenario. It helps assess the client's oxygenation status quickly, which is crucial in a client with signs of respiratory distress, such as shortness of breath and bilateral pulmonary crackles. Ordering a chest X-ray (Choice A) may be necessary later but does not address the immediate need for oxygen assessment. Obtaining an order for a complete blood count (Choice C) is not the priority in this situation as it does not directly address the client's respiratory distress. Instructing the patient to stay in bed (Choice D) does not address the underlying issue of potential hypoxia and respiratory compromise.

Correct Answer: D

Rationale: In this situation, the nurse should first stabilize the client's neck to prevent potential spinal cord injuries. Logrolling the client or performing other assessments should only be done after ensuring spinal stabilization. Opening the airway immediately is important in cases of airway obstruction, but stabilizing the neck takes priority in this scenario. Performing a complete neurological assessment may delay immediate stabilization, which is crucial in suspected spinal injuries.

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.

Correct Answer: D

Rationale: The correct answer is D. The Department of Health (DOH) retains regulatory functions for inspecting food establishments, and it is not transferred to local government units. Choices A, B, and C are correct because devolution allows people to participate in policymaking for healthcare, enhances community life quality, and empowers the barangay to set criteria for healthcare service prioritization.
