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: B

Rationale: A nurse with Marfan syndrome who is postmenopausal can safely care for the client because Marfan syndrome does not affect the ability to care for this client, and postmenopausal status minimizes the risk of radiation exposure affecting reproductive health. Choice A is incorrect because pregnancy increases the risk of radiation exposure to the fetus. Choice C is incorrect because a nurse with a cold may have a compromised immune system and should not be exposed to radiation therapy. Choice D is incorrect because lactation can increase the risk of radiation exposure to breast tissue.

Correct Answer: C

Rationale: A temperature of 102�F (38.9�C) is the most important assessment finding to report to the healthcare provider in a client with pancreatitis and a history of alcoholism. Fever in this context can indicate infection, which is a serious complication requiring immediate intervention. Nausea and vomiting (choice A) are common symptoms of pancreatitis but may not require immediate intervention unless severe. Epigastric pain radiating to the back (choice B) is a classic symptom of pancreatitis and should be addressed, but a fever takes precedence. Mild jaundice (choice D) may be present in pancreatitis but is not as urgent as a high temperature signaling possible infection.

Correct Answer: A

Rationale: The number of home-bound seniors visited is the best measure of the project's effectiveness as it directly reflects the reach and impact of the program. Choice B is incorrect as it does not directly relate to the effectiveness of the program for home-bound seniors. Choice C is irrelevant as the average annual income of home-bound members is not a direct measure of the program's effectiveness. Choice D, calls showing interest, is not as direct a measure as the actual visits to the home-bound seniors.

Correct Answer: D

Rationale: An elevated ammonia level of 80 mcg/dL indicates hepatic encephalopathy, a serious complication of liver cirrhosis that requires immediate intervention. Ammonia is a neurotoxin that accumulates in the blood due to impaired liver function, leading to cognitive impairment and altered mental status. Monitoring and lowering ammonia levels are crucial in managing hepatic encephalopathy to prevent further neurological deterioration. Prothrombin time, bilirubin, and albumin levels are important parameters in assessing liver function and overall health status in clients with liver cirrhosis, but an elevated ammonia level poses an immediate threat to neurological function and warrants prompt attention.
