Systolic blood pressure starts to decrease in which class of hemorrhage?

Correct Answer: C

Rationale: In Class 2 hemorrhage, systolic blood pressure starts to decrease due to significant blood loss (15-30%). This reduction triggers compensatory mechanisms to maintain perfusion. In Class 0, there is no blood loss, so blood pressure remains stable. In Class 1, minimal blood loss occurs, causing little impact on blood pressure. In Class 3, severe blood loss leads to a rapid decrease in blood pressure, making it unlikely for systolic blood pressure to start decreasing gradually.

Correct Answer: A

Rationale: The correct answer is A because cardiac tamponade is a life-threatening condition where fluid accumulation in the pericardial sac compresses the heart. Surgical intervention, such as pericardial drainage or pericardiotomy, is often required to relieve the pressure on the heart. Choice B, needle pericardiocentesis, is a temporary measure and may not definitively manage the condition. Choice C, Beck's triad (hypotension, elevated jugular venous pressure, muffled heart sounds), may be present but is not always diagnostic. Choice D, Kussmaul breathing (deep, labored breathing), is indicative of other conditions like metabolic acidosis rather than cardiac tamponade.

Correct Answer: D

Rationale: The correct answer is D: "Decreased pulse pressure." Airway compromise typically leads to increased pulse pressure due to increased sympathetic activity. A: "Change in voice" can indicate vocal cord dysfunction. B: "Stridor" is a high-pitched sound during inspiration, indicating upper airway obstruction. C: "Tachypnea" is rapid breathing, a compensatory mechanism in response to airway compromise.

Correct Answer: A

Rationale: The correct answer is A because holding oneself accountable involves taking responsibility for one's actions, including admitting mistakes and apologizing for them. This demonstrates honesty, integrity, and a willingness to learn and improve. Choices B, C, and D are incorrect because they do not directly address the concept of accountability. Speaking positively, working with diverse backgrounds, and caring about others are important qualities, but they do not specifically relate to the act of holding oneself accountable.

Correct Answer: C

Rationale: The correct answer is C because negligence refers to the failure to provide reasonable care that results in unintended harm or injury to a person. This involves a breach of duty of care leading to harm. Choice A and B refer to physical contact without permission, which is not directly related to negligence. Choice D is about emotional harm rather than negligence involving a failure to provide proper care.
