Postmortem care includes

Correct Answer: C

Rationale: The correct answer is C: Positioning the body in proper alignment. This is because proper alignment helps maintain dignity, prevent postmortem changes, and facilitate care such as cleaning and dressing. Covering the body completely (A) is important for privacy but not part of postmortem care. Propping the eyes open (B) is unnecessary and can be disturbing. Leaving on the oxygen (D) is not typically done as it is not beneficial after death.

Correct Answer: A

Rationale: The correct answer is A: The type of landing surface involved. Evaluating the landing surface is crucial in predicting injuries as it can impact the distribution of forces on the body. A hard surface can result in more severe injuries compared to a softer surface. The other choices are incorrect. B (ambient temperature) is irrelevant to predicting injuries from a fall. C (neurological status) is important but not as directly related to predicting injuries from a fall as the landing surface. D (body parts struck) is important post-injury assessment but not as critical in predicting injuries at the scene.

Correct Answer: A

Rationale: The correct approach is A: Wait for responding police to control the situation and say that it is safe for EMS. This is the safest option because the scene has not been secured by law enforcement, and your safety is paramount. By waiting for the police to arrive and ensure the scene is safe, you are minimizing the risk of potential harm to yourself and allowing for a coordinated and controlled response. It is crucial to prioritize personal safety and follow established protocols in such high-risk situations. Summary of other choices: B: Waiting for police to arrive before entering is important, but going in with them could still expose you to unnecessary risk. C: Driving up to the driveway without police presence could put you in harm's way and compromise scene safety. D: Heading into the house without police clearance is extremely dangerous and could escalate the situation further.

Correct Answer: A

Rationale: The correct answer is A: The intravenous administration of 2-4 mg of morphine per a medical-control physician's order. Morphine is commonly used in myocardial infarction to reduce cardiac preload and afterload by dilating blood vessels, reducing workload on the heart. This helps improve blood flow to the heart muscle. Choice B is incorrect because medications like procainamide, atropine, and verapamil are used to control specific dysrhythmias, not specifically to reduce preload and afterload. Choice C is incorrect as sublingual nitroglycerin therapy primarily works by dilating coronary arteries to improve blood flow to the heart, rather than specifically reducing preload and afterload. Choice D is incorrect as high-flow oxygen therapy helps to increase oxygen delivery to tissues but does not directly reduce preload and afterload.

Correct Answer: D

Rationale: The correct answer is D: Diphenhydramine. Diphenhydramine is an anticholinergic medication that can effectively reverse the signs and symptoms of dystonia by blocking acetylcholine receptors. This helps reduce muscle spasms and involuntary movements associated with dystonia. Promethazine (A) and morphine sulfate (B) are not typically used to treat dystonia. Lidocaine (C) is a local anesthetic and is not effective in treating dystonia. Diphenhydramine is the most appropriate choice due to its mechanism of action in blocking acetylcholine receptors, making it effective in reversing dystonia symptoms.
