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: C

Rationale: Developing a safety plan is the most appropriate intervention as it helps the family prepare for potential emergencies and enhances their overall sense of security. Providing information on local crime statistics may raise awareness but does not directly address safety planning. Teaching self-defense techniques may have limited effectiveness in a high-crime area where the family may face multiple threats. Encouraging the family to move to a safer neighborhood is not always feasible due to various reasons such as financial constraints or social ties to the current community.

Correct Answer: A

Rationale: Setting up dental clinics in accessible locations is the most effective intervention to improve access to dental care. By having dental clinics in easily reachable places, community members are more likely to seek and utilize dental services. Distributing flyers may raise awareness, but it may not address the issue of physical accessibility to dental care. Offering transportation vouchers could help with transportation barriers but might not address the core issue of proximity to dental services. Partnering with local businesses to promote dental health is a good initiative, but it may not directly improve access to dental care as setting up clinics in accessible locations would.

Correct Answer: B

Rationale: A nurse with Marfan syndrome who is postmenopausal can safely care for the client because Marfan syndrome does not affect the ability to care for this client, and postmenopausal status minimizes the risk of radiation exposure affecting reproductive health. Choice A is incorrect because pregnancy increases the risk of radiation exposure to the fetus. Choice C is incorrect because a nurse with a cold may have a compromised immune system and should not be exposed to radiation therapy. Choice D is incorrect because lactation can increase the risk of radiation exposure to breast tissue.

Correct Answer: A

Rationale: Muscle weakness and cramps are characteristic signs of hypokalemia, a condition marked by low levels of potassium in the blood. Potassium is essential for proper muscle function, and its deficiency can lead to muscle weakness and cramps. In the context of a client with a nasogastric tube to low intermittent suction, the loss of potassium through suctioning can contribute to the development of hypokalemia. Nausea and vomiting (choice B) are more commonly associated with gastrointestinal issues rather than hypokalemia. Constipation (choice C) is not a typical finding of hypokalemia; instead, it can be a sign of other gastrointestinal problems. Increased blood pressure (choice D) is not a direct manifestation of hypokalemia; in fact, low potassium levels are more commonly associated with decreased blood pressure.
