Which of the following statements concerning intraosseous infusion is TRUE?

Correct Answer: B

Rationale: Rationale for Correct Answer (B): 1. Aspiration of bone marrow confirms appropriate positioning of the needle: This statement is true because when the needle is correctly placed within the bone marrow cavity, aspiration of bone marrow confirms proper positioning and ensures that the infusion will be successful. Summary of Incorrect Choices: A: Only crystalloid solutions may be safely infused through the needle - Incorrect, as both crystalloid and colloid solutions can be infused through the intraosseous route. C: Intraosseous infusion is the preferred route for volume resuscitation in small children - Incorrect, as while it is commonly used in pediatric emergencies, it may not always be the preferred route depending on the situation. D: Intraosseous infusion may be utilized indefinitely - Incorrect, as intraosseous infusion is typically considered a temporary measure and is not meant for long-term use.

Correct Answer: C

Rationale: The correct answer is C: Chest x-ray. In this scenario, the patient is at risk for thoracic injuries due to the motor vehicle crash and the need for mechanical ventilation. A chest x-ray is essential to assess for potential life-threatening conditions such as pneumothorax, hemothorax, or pulmonary contusions. This information is crucial for the safe transfer of the patient to another facility. A: FAST exam is typically used to assess for intra-abdominal bleeding and is not mandatory in this case. B: Lateral cervical spine x-ray is not necessary as the patient is already in full spinal protection and needs definitive neurosurgical care, not initial evaluation. D: Administration of methylprednisolone is not mandatory at this stage and should be based on specific guidelines for spinal cord injury management.

Correct Answer: B

Rationale: The correct answer is B: "Preparation for laparotomy while initiating fluid resuscitation". In a trauma scenario with hemodynamic instability like this, the priority is to address potential intra-abdominal bleeding with a laparotomy. Fluid resuscitation is crucial to maintain perfusion and stabilize the patient before surgery. The other choices are incorrect because: A: "Transfusion of FFP and platelets" is not the immediate priority in this scenario as it does not address the source of bleeding. C: "Resuscitation with crystalloid and pRBC until base excess is normal" is not ideal as it delays definitive treatment and may worsen the patient's condition. D: "Fluid resuscitation and angioembolization" may be considered in stable patients, but in this case, the patient is hemodynamically unstable and needs immediate surgical intervention.

Correct Answer: D

Rationale: The correct answer is D: The resident. Residents are the focal point of care, and their needs and preferences should guide the care team. Physicians provide medical expertise but residents are the primary recipients of care. Nurses and nursing assistants play crucial roles in providing direct care, but ultimately, the resident's well-being is the top priority.

Correct Answer: D

Rationale: The correct answer is D because when a nursing assistant is suspected of abuse, immediate action is necessary to ensure the safety of residents. Suspending the nursing assistant allows for a thorough investigation without putting residents at risk. Choice A is incorrect as discussing the problem openly may compromise the investigation. Choice B is incorrect as the nursing assistant should be removed from the situation during investigation. Choice C is incorrect as confidentiality is crucial in abuse cases to protect the reporter and the victim.
