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: Creating a confidential hotline for reporting abuse is the most critical intervention when addressing domestic violence. A hotline offers a safe and confidential way for individuals experiencing abuse to report incidents, seek help, and access support services. This intervention prioritizes immediate safety and support for victims. Providing education on the signs of domestic violence (Choice A) is important for prevention but may not address the urgent needs of individuals currently experiencing abuse. Setting up a support group for survivors (Choice B) is valuable for emotional support but may not reach those who are not yet identified as survivors. Partnering with local law enforcement to increase patrols (Choice C) focuses more on the law enforcement response rather than providing a direct avenue for victims to seek help and support.

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.

Correct Answer: A

Rationale: The correct answer is early adolescent girls. Scoliosis is most commonly diagnosed during early adolescence, with girls being more affected than boys. Including early adolescent girls in the screening clinic aligns with the age group that is at higher risk for scoliosis. Late adolescent boys (choice B) are less likely to develop scoliosis compared to early adolescent girls. 7-10 year old boys (choice C) are typically younger than the age group where scoliosis is commonly diagnosed. Preschoolers of both genders (choice D) are too young for scoliosis screening as the condition usually manifests during adolescence.

Correct Answer: A

Rationale: Installing grab bars in the bathroom is crucial to reducing the elderly client's risk of falling at home. Grab bars provide physical support and stability, especially in areas like the bathroom where slips and falls are common among older adults. While providing a walker for ambulation (Choice B) can assist with mobility, it may not directly address the environmental hazards at home. Educating the client on fall prevention strategies (Choice C) is important but may not be sufficient if the physical environment is not modified to reduce fall risks. Referring the client to a physical therapist (Choice D) may help improve strength and balance but does not directly address the immediate environmental risk of falling at home.
