Correct Answer: A

Rationale: The most important intervention for the nurse to implement prior to the discharge of a homeless client with alcohol dependency who had a tuberculin skin test prescribed is to identify how the client will follow-up to have the results read. This is crucial to ensure proper diagnosis and treatment. Providing written information (Choice B) is helpful but not as critical as ensuring the follow-up plan. Determining if the client understands the purpose of the test (Choice C) is important but not as immediate as ensuring the follow-up plan. Explaining when the results should be read (Choice D) is important, but the priority is to make sure the client has a plan in place for follow-up.

Correct Answer: A

Rationale: Using an albuterol inhaler before exercising is appropriate for clients with COPD to prevent exercise-induced bronchospasm.

Correct Answer: A

Rationale: Validating that the children sent home did develop chickenpox is the most crucial initial step for the nurse. This intervention ensures that the appropriate public health measures are implemented for the containment of chickenpox. Reporting a viral endemic or confirming the number of children with symptoms may be important but are secondary to confirming the diagnosis. Determining the number of people exposed comes after confirming the diagnosis to assess the extent of the outbreak and implement necessary control measures.

Correct Answer: A

Rationale: The regular pulsation at the epigastric area when the client is supine is a normal finding. This phenomenon is caused by the regular and recurrent expansion and contraction of an artery due to waves of pressure caused by the ejection of blood from the left ventricle. Choices B, C, and D describe abnormal findings during a physical assessment. A loud, harsh murmur at the second right intercostal space indicates an abnormal heart sound, dullness over the lung fields may suggest consolidation or fluid in the lungs, and increased tactile fremitus can be a sign of lung consolidation or pathology.

Correct Answer: D

Rationale: The correct answer is D: number of people without access to healthcare. Ensuring access to healthcare is fundamental to addressing a wide range of health issues and is a priority for improving overall community health. Option A, overuse of diagnostic technology, though important, is not the highest priority when considering basic access to healthcare. Option B, government-based health insurance, is relevant but may not directly address the issue of lack of access for all individuals. Option C, neonatal and infant mortality rates, is crucial but addressing access to healthcare for all individuals is a more immediate and foundational concern for the community health project.
