Which statement is true regarding the arterial system?

Correct Answer: B

Rationale: The correct answer is B: The arterial system is a high-pressure system. Arteries carry blood away from the heart to various parts of the body, and they experience high pressure due to the force exerted by the pumping heart. This pressure is essential for delivering oxygen and nutrients efficiently throughout the body. Therefore, choice B is correct. Choices A, C, and D are incorrect because arteries are not always large in diameter, the walls of arteries are thicker than veins for maintaining higher pressure, and arteries do not greatly expand like veins to accommodate large blood volume increases.

Correct Answer: C

Rationale: The correct sequence (C) starts with greeting the patient to establish rapport, then inviting the patient's story to understand their perspective. Next, establishing the agenda ensures all concerns are addressed. Expanding and clarifying the patient's story allows for a comprehensive assessment. Finally, negotiating a plan involves collaborative decision-making. Option A is incorrect because establishing rapport is essential before setting the agenda. Option B is incorrect as inviting the patient's story should come before negotiating a plan. Option D is incorrect as negotiating a plan should be the final step after understanding the patient's story.

Correct Answer: B

Rationale: The correct answer is B: Flight of ideas. Flight of ideas is a symptom commonly seen in manic episodes, where thoughts are rapidly moving from one idea to another, making it challenging to follow the conversation. In this scenario, the patient's fast and erratic speech pattern with disjointed ideas aligns with the classic presentation of flight of ideas. Derailment (A) refers to a sudden shift in the topic without any apparent connection, which is not the case here. Circumstantiality (C) involves providing unnecessary detail before reaching the main point, which does not fit the description provided. Incoherence (D) refers to speech that is illogical and incomprehensible, which is not the primary feature presented in the scenario.

Correct Answer: A

Rationale: The correct answer is A because evidence-based nursing practice involves combining clinical expertise with the use of nursing research to provide the best care for patients while considering the patient's values and circumstances. This approach ensures that nursing interventions are based on the best available evidence, tailored to individual patient needs, and aligned with patient preferences. It emphasizes the integration of research evidence, clinical expertise, and patient values to optimize patient outcomes. Choice B is incorrect because evidence-based nursing practice involves a comprehensive review of multiple research studies, not just one or two articles. Choice C is incorrect because completing a literature search is just one step in the evidence-based practice process, which also involves critically appraising and applying the evidence to patient care. Choice D is incorrect because evidence-based practice focuses on using research evidence, not value-based resources, to guide nursing actions.

Correct Answer: D

Rationale: The correct answer is D because trigger finger can be caused by Dupuytren's disease, ganglion of the tendon sheath, or rheumatoid arthritis. Dupuytren's disease can lead to the formation of nodules in the palm that can affect finger movement. Ganglion of the tendon sheath can cause tendon swelling and lead to triggering of the finger. Rheumatoid arthritis can result in inflammation of the tendon sheaths, causing trigger finger. Therefore, all of the above conditions are part of the differential diagnosis for trigger finger. Choices A, B, and C are incorrect individually because trigger finger can be associated with each condition separately.
