Correct Answer: C

Rationale: For a client with COPD requiring assistance for short-distance ambulation, suggesting a bedside commode for toileting is the most appropriate intervention. This recommendation helps reduce the need for the client to walk long distances, thereby minimizing the risk of exertion and potential falls. Disconnecting oxygen during ambulation (Choice A) is not safe for a client with COPD, as oxygen therapy should be continuous. Administering a breathing treatment before ambulation (Choice B) may not directly address the client's need for assistance with toileting. Asking for additional assistance (Choice D) can be beneficial but providing a bedside commode specifically addresses the current issue of ambulating short distances for toileting.

Correct Answer: C

Rationale: Peripheral edema in a client with cirrhosis can indicate fluid overload and worsening liver function, necessitating immediate intervention to prevent further complications such as respiratory distress, cardiac issues, or renal impairment. Jaundice (choice A) is a common manifestation of cirrhosis but may not require immediate intervention unless severe. Ascites (choice B) is also a common complication of cirrhosis that may require intervention but is not as urgent as addressing peripheral edema. Spider angiomas (choice D) are typically benign skin lesions associated with cirrhosis but do not require immediate intervention unless bleeding or rupture occurs.

Correct Answer: B

Rationale: The correct answer is B: botulism toxin. The symptoms described, including symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth, are classic manifestations of botulism, which is caused by a toxin produced by Clostridium botulinum. This toxin affects the nervous system, leading to muscle weakness and paralysis. Choice A, ricin, typically presents with gastrointestinal symptoms and organ failure. Choice C, sulfur mustard, causes blistering skin and respiratory issues. Choice D, yersinia pestis, is associated with the plague and presents with fever, chills, weakness, and swollen lymph nodes.

Correct Answer: D

Rationale: The correct answer is D: number of people without access to healthcare. Ensuring access to healthcare is fundamental to addressing a wide range of health issues and is a priority for improving overall community health. Option A, overuse of diagnostic technology, though important, is not the highest priority when considering basic access to healthcare. Option B, government-based health insurance, is relevant but may not directly address the issue of lack of access for all individuals. Option C, neonatal and infant mortality rates, is crucial but addressing access to healthcare for all individuals is a more immediate and foundational concern for the community health project.

Correct Answer: C

Rationale: The correct answer is C. Sudden, severe abdominal pain can indicate a perforated ulcer, which is a medical emergency requiring immediate intervention. Epigastric tenderness (choice A) may be expected in a client with peptic ulcer disease but does not necessarily require immediate intervention. Hypoactive bowel sounds (choice B) are concerning but not as urgent as sudden, severe abdominal pain. Hyperactive bowel sounds (choice D) are more indicative of conditions like gastroenteritis rather than a perforated ulcer, making it a less critical finding compared to sudden, severe abdominal pain.
