The least likely cause of a depressed level of consciousness in the multisystem injured patient is:

Correct Answer: C

Rationale: The correct answer is C: Hyperglycemia. In a multisystem injured patient, hyperglycemia is the least likely cause of a depressed level of consciousness because it typically does not directly affect brain function or consciousness. Shock (A), head injury (B), and impaired oxygenation (D) are more likely to cause a depressed level of consciousness in this patient population due to their direct impact on brain perfusion, injury, and oxygen delivery, respectively. Hyperglycemia, although an important consideration in the critically ill patient, is not a primary driver of altered consciousness in the setting of multisystem trauma.

Correct Answer: C

Rationale: The correct answer is C: "FAST exam." In this scenario, the patient presents with signs of hypovolemic shock likely due to internal bleeding from the chest wound. FAST exam (Focused Assessment with Sonography in Trauma) is a rapid bedside ultrasound used to assess for free fluid in the abdomen or pericardium, which can help identify the source of bleeding. This is crucial for immediate management as it can guide further interventions such as surgery or angiography. Choice A: "CT scan of the chest" is not the most immediate step as it takes time and may not provide rapid information needed for immediate management. Choice B: "12 lead ECG" is not the priority in this situation as the patient is hemodynamically unstable and requires rapid assessment for potential life-threatening bleeding. Choice D: "Begin infusion of RBCs" is important, but identifying the source of bleeding is crucial before deciding on the need for blood transfusion.

Correct Answer: C

Rationale: The correct answer is C because the chain of command refers to the hierarchical structure within an organization that outlines the line of authority and communication. This ensures that decisions and information flow efficiently from top management to frontline employees. Option A is incorrect as it describes legal responsibility. Option B is incorrect as it refers to a shift supervisor, not the entire chain of command. Option D is incorrect as it describes a specific department, not the overall structure of authority. Ultimately, understanding the chain of command is crucial for effective communication and decision-making within an organization.

Correct Answer: B

Rationale: The correct answer is B: Protect privacy of health information. HIPAA was enacted to safeguard individuals' sensitive health information, ensuring confidentiality and security. This is crucial in maintaining trust between patients and healthcare providers. Choices A, C, and D are incorrect as they do not directly relate to the primary purpose of HIPAA, which is to regulate the use and disclosure of protected health information. Nursing assistants' insurance coverage, care procedures, and abuse prevention are important but not the main focus of HIPAA.

Correct Answer: D

Rationale: The correct answer is D: Taste. Taste is not typically used in making observations because observations rely on external stimuli that can be seen, touched, or smelled. Taste involves consuming food or drink, which is not a common method of observation. Sight (A), touch (B), and smell (C) are commonly used senses in making observations. Each of these senses provides valuable information about the external world, making them essential for observation. Taste, on the other hand, is more subjective and personal, making it less reliable and applicable for objective observations.
