You are cleaning the back of the truck after transporting a trauma patient to the emergency department. Which of the following contaminated items should not be placed in a plastic biohazard bag?

Correct Answer: A

Rationale: The correct answer is A: Plastic IV catheter. This should not be placed in a plastic biohazard bag because it is a sharp item that can puncture the bag and potentially harm someone handling it. It should be disposed of in a sharps container to ensure safe handling and disposal. Choices B, C, and D are all items that can be safely placed in a plastic biohazard bag as they do not pose a risk of puncturing the bag or causing harm during disposal.

Correct Answer: B

Rationale: The correct answer is B (2-5 mg of albuterol administered directly down the ET tube). After rapid sequence intubation in an adult with status asthmaticus, albuterol can be administered directly down the endotracheal tube to rapidly dilate the airways. The dose of 2-5 mg is appropriate for adult patients in this situation. Choice A (3 mg of levalbuterol administered directly down the ET tube) is incorrect because levalbuterol is not typically administered directly down the endotracheal tube, and the dose provided is not within the standard range for adult patients. Choice C (2.5 mg of albuterol in 3-mL solution, nebulized and delivered with ventilation) is incorrect because nebulized albuterol may not be as effective in rapidly dilating the airways compared to direct administration down the endotracheal tube in this critical situation. Choice D (

Correct Answer: D

Rationale: The correct answer is D because during an allergic reaction, mast cells degranulate, releasing histamines and other inflammatory mediators into the bloodstream. This leads to vasodilation, increased vascular permeability, and smooth muscle contraction, causing symptoms like itching, hives, and difficulty breathing. Choice A is incorrect because mast cells do not retain vasoactive amines; they release them. Choice B is incorrect as there is no hypermetabolic state associated with an allergic reaction. Choice C is incorrect because anaerobic metabolism is not a typical response to an allergic reaction.

Correct Answer: D

Rationale: The correct answer is D: Initiate full resuscitation efforts including advanced cardiac life support, and contact medical control. Rationale: 1. Patient is pulseless and apneic, indicating cardiac arrest. 2. Legal DNR order does not apply in this scenario as patient's collapse is sudden and not anticipated. 3. The priority is to provide immediate life-saving measures. 4. Advanced cardiac life support increases chances of successful resuscitation. 5. Contacting medical control ensures appropriate guidance and documentation. Summary: A: Waiting for approval could delay critical interventions. B: Stopping resuscitation based solely on the legal DNR order is inappropriate in this emergency. C: Allowing the family to override the legal order puts the patient at risk and is not recommended.

Correct Answer: C

Rationale: The correct next step is to perform endotracheal intubation (Choice C). In this scenario, the patient's presentation with a GCS of 6, dilated pupil, and contralateral weakness indicates significant neurological compromise likely due to increased intracranial pressure. Endotracheal intubation is crucial to protect the airway and ensure adequate oxygenation and ventilation in such critical conditions. Administering medications or performing diagnostic tests like a CT-scan (Choice A), decadron (Choice B), or mannitol (Choice D) should be secondary to securing the airway and stabilizing the patient's condition.
