Correct Answer: A

Rationale: The correct answer is A: Hemoglobin of 12 g/dL. Erythropoietin therapy stimulates red blood cell production, leading to an increase in hemoglobin levels. A hemoglobin level of 12 g/dL indicates that the therapy is effective in managing anemia associated with chronic kidney disease. Choice B, a reticulocyte count of 1%, is not a direct indicator of the effectiveness of erythropoietin therapy. Choice C, a blood pressure of 130/80 mm Hg, is important to monitor in clients with chronic kidney disease but does not specifically indicate the effectiveness of erythropoietin therapy. Choice D, a serum ferritin level of 100 ng/mL, is related to iron stores in the body and may be monitored during erythropoietin therapy but does not directly reflect the therapy's effectiveness in increasing red blood cell production.

Correct Answer: A

Rationale: The correct short-term goal for the client in this scenario is option A: 'Eat 50% of six small meals each day by the end of the week.' This goal is specific, measurable, and time-bound, which aligns with the SMART criteria for goal setting in nursing care. It addresses the client's nutritional needs directly, focusing on increasing meal frequency to meet body requirements and counteract weight loss. Option B, 'Gain 5 pounds by the end of the month,' is not as suitable as it lacks specificity and a short-term timeline, making it less achievable within the immediate care plan. Option C, 'Have increased caloric intake,' is vague and does not provide a measurable target for the client to work towards. Option D, 'Show improved nutritional status,' is a broad goal that lacks the specificity needed for effective short-term goal setting in nursing care. Therefore, option A is the most appropriate choice for this client's short-term goal.

Correct Answer: D

Rationale: Conducting a community needs assessment is the most appropriate initial intervention when addressing domestic violence in the community. This step helps the nurse identify existing resources, gaps, and specific needs of the community related to domestic violence. By understanding the community's needs through a needs assessment, the nurse can tailor subsequent interventions effectively. Option A, establishing a support group, may be beneficial later but should not be the first step. Developing educational materials (Option B) and partnering with law enforcement (Option C) are important strategies; however, without understanding the community's specific needs through a needs assessment, the interventions may not be as targeted or effective.

Correct Answer: D

Rationale: Decreased deep tendon reflexes are a critical finding in hypokalemia that indicates severe potassium deficiency affecting neuromuscular function. Immediate intervention is necessary to prevent life-threatening complications such as respiratory failure or cardiac arrhythmias. Muscle weakness, irregular heart rate, and increased urinary output are also associated with hypokalemia but do not pose the same level of urgency as decreased deep tendon reflexes.

Correct Answer: B

Rationale: A reduction in fasting blood glucose levels indicates the effectiveness of the diabetes management education provided. Monitoring blood glucose levels is a crucial aspect of diabetes management, and a decrease in average readings signifies improvement in managing blood sugar levels. Choices A, C, and D are not direct outcome evaluations related to the effectiveness of the education provided in managing diabetes. Parking convenience, attendance, and teaching strategies are not direct indicators of the impact on the clients' health outcomes.
