A client with chronic kidney disease is receiving erythropoietin therapy. Which finding indicates that the therapy is effective?

• A. Hemoglobin of 12 g/dL.
• B. Reticulocyte count of 1%.
• C. Blood pressure of 130/80 mm Hg.
• D. Serum ferritin level of 100 ng/mL.

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.

A community health nurse is addressing the issue of elder abuse in the community. Which intervention should be prioritized?

• A. providing education on the signs of elder abuse
• B. setting up a support group for elder abuse survivors
• C. partnering with local law enforcement to increase patrols
• D. creating a confidential hotline for reporting abuse

Correct Answer: D
Rationale: The prioritized intervention for addressing elder abuse in the community should be the creation of a confidential hotline for reporting abuse. A confidential hotline offers a safe and accessible way for individuals to report elder abuse and seek help promptly. Providing education on the signs of elder abuse (Choice A) is important but may not directly address immediate reporting and intervention needs. Setting up a support group for elder abuse survivors (Choice B) is beneficial for emotional support but may not address the primary need for reporting abuse. Partnering with local law enforcement to increase patrols (Choice C) focuses on prevention rather than providing a direct reporting mechanism for victims.

A public health nurse is addressing the issue of childhood lead poisoning in a low-income community. Which intervention should be prioritized?

• A. Providing free blood lead level testing for children
• B. Distributing pamphlets on the dangers of lead exposure
• C. Conducting home inspections for lead-based paint
• D. Educating parents about lead poisoning prevention

Correct Answer: A
Rationale: Providing free blood lead level testing for children should be prioritized as it directly identifies children who are at risk and in need of intervention. This intervention allows for early detection and timely implementation of necessary measures to prevent further lead exposure or address existing poisoning. Distributing pamphlets (choice B) may raise awareness but does not directly identify at-risk children. Conducting home inspections (choice C) is important but may not be as immediate and targeted as blood lead level testing. Educating parents (choice D) is essential but may not directly identify and address individual cases of lead poisoning as testing does.

On a day when the temperature is expected to drop below freezing during the night, the nurse is asked to determine which homeless adults are most in need of the limited spaces available in a shelter. It is most important for which person to be admitted at night?

• A. an adult who was hit by a car 3 weeks ago
• B. a young person with diabetes mellitus
• C. a middle-aged person who has hypertension
• D. an older person who is malnourished

Correct Answer: D
Rationale: Malnourished individuals are at higher risk of severe complications from cold exposure due to their weakened immune system and decreased ability to regulate body temperature. This places them at a greater risk of hypothermia and other cold-related conditions, making them the most vulnerable group in need of shelter. Choice A is not the most critical as the injury is from 3 weeks ago and should have received appropriate medical care by now. Choice B, a young person with diabetes mellitus, while vulnerable, can manage their condition with proper medication and care. Choice C, a middle-aged person with hypertension, may need monitoring but is less susceptible to immediate harm from cold exposure compared to a malnourished individual.
