A community health nurse is planning an intervention to reduce the incidence of type 2 diabetes in the community. Which strategy is most effective?

• A. Hosting cooking classes on preparing healthy meals
• B. Offering free blood glucose screenings
• C. Distributing pamphlets on diabetes prevention
• D. Organizing a community walking program

Correct Answer: A
Rationale: The most effective strategy to reduce the incidence of type 2 diabetes in the community is hosting cooking classes on preparing healthy meals. This intervention provides practical skills and education that can directly impact dietary habits, leading to a decreased risk of developing type 2 diabetes. Offering free blood glucose screenings (Choice B) may help in early detection but does not address prevention. Distributing pamphlets on diabetes prevention (Choice C) provides information but lacks the interactive and hands-on approach of cooking classes. Organizing a community walking program (Choice D) promotes physical activity, which is beneficial, but dietary changes have a more significant impact on preventing type 2 diabetes.

After coronary artery bypass graft surgery, a male client is admitted to the coronary care unit. Which nursing diagnosis is of the highest priority?

• A. Ineffective breathing pattern.
• B. Impaired gas exchange.
• C. Acute pain.
• D. Risk for infection.

Correct Answer: B
Rationale: Impaired gas exchange is the highest priority nursing diagnosis because it directly impacts the client's oxygenation. Following coronary artery bypass graft surgery, ensuring adequate oxygen exchange is crucial for the client's recovery. Ineffective breathing pattern, although important, may not be as critical as impaired gas exchange in the immediate postoperative period. Acute pain, while significant, can be managed effectively with appropriate interventions and is not as emergent as addressing impaired gas exchange. Risk for infection is also a valid concern post-surgery, but ensuring optimal gas exchange takes precedence to prevent complications associated with inadequate oxygenation.

A client with a history of hypertension is prescribed enalapril (Vasotec). Which statement by the client indicates a need for further teaching?

• A. I will monitor my blood pressure regularly.
• B. I will report any signs of infection to my healthcare provider.
• C. I will avoid using salt substitutes.
• D. I will increase my intake of potassium-rich foods.

Correct Answer: D
Rationale: The correct answer is D. Increasing potassium intake can lead to hyperkalemia, especially in clients taking ACE inhibitors like enalapril. Hyperkalemia is a potential side effect of ACE inhibitors and can be exacerbated by consuming potassium-rich foods. Monitoring blood pressure regularly (A) is important when taking antihypertensive medications. Reporting signs of infection (B) is crucial as ACE inhibitors can lower the immune response. Avoiding salt substitutes (C) is necessary because they may contain potassium chloride, leading to increased potassium levels, which can be harmful in combination with ACE inhibitors.

A teenage boy with a history of recurring atopic dermatitis (eczema) tells the school nurse that he wants to play high school football. Which action should the nurse take?

• A. encourage the teenager to join the swim team instead of the football team
• B. notify the parents of the problems associated with perspiration for those with eczema
• C. tell the teenager to shower with a non-perfumed soap immediately after practice
• D. inform the football coach of the teenager's skin condition and its manifestations

Correct Answer: C
Rationale: The correct action for the nurse to take is to advise the teenager to shower with a non-perfumed soap immediately after practice. This recommendation can help reduce the risk of eczema flare-ups by removing sweat and irritants from the skin. Choice A is incorrect as it does not address the specific concerns related to eczema and football. Choice B, notifying the parents of perspiration problems, is not as direct as instructing the teenager on proper skincare. Choice D, informing the football coach, is not the most immediate and relevant action to address the teenager's individual needs.
