Your suspected myocardial infarction patient has exhibited ST elevation in Leads II, III, aVF on the electrocardiogram. What area of the heart do you suspect is being damaged?

Correct Answer: B

Rationale: The correct answer is B: Inferior wall. ST elevation in Leads II, III, aVF indicates an inferior wall myocardial infarction, commonly caused by occlusion of the right coronary artery. Lead II views the inferior part of the heart, and Leads III/aVF view the inferior and posterior parts. This pattern suggests damage to the inferior wall supplied by the right coronary artery. Other choices are incorrect as ST elevation in these leads does not correspond to lateral (A), anterior (C), or septal (D) wall infarctions.

Correct Answer: B

Rationale: The correct answer is B: Negligence charges could be brought against the paramedic in charge of the unit. Rationale: 1. Negligence: In this scenario, the paramedic failed to ensure the equipment was properly charged, leading to the death of the patient. 2. Duty of Care: The paramedic had a duty to ensure the equipment was functional to provide appropriate care to the patient. 3. Breach of Duty: By not ensuring the defibrillator had adequate battery power, the paramedic breached their duty of care. 4. Proximate Cause: The lack of functioning equipment directly contributed to the patient's death. 5. Legal Liability: Negligence in providing care can result in legal charges being brought against the individual responsible for the patient's care. Summary: A: Manslaughter charges are not applicable as there was no intent to harm the patient. C: Battery charges are not relevant as it refers to physical harm, not the lack of battery power in equipment

Correct Answer: D

Rationale: The correct answer is D because the absolute volume of blood loss required to produce shock in children is typically lower than in adults due to their smaller size. A: Vital signs are age-related in children, so they may differ from those in adults. B: Children actually have limited physiologic reserves compared to adults, making them more vulnerable to shock. C: Tachycardia is a common response to hypovolemia in children, but it is not the only physiologic response. Therefore, D is false because children require less blood loss to develop shock compared to adults.

Correct Answer: A

Rationale: The correct answer is A: Log-rolling may be destabilizing to fractures from T12 to L1. This is true because log-rolling involves rotating a patient to prevent movement of the spine, but in thoracic spine injuries from T12 to L1, this maneuver can cause further damage and destabilize the fractures. Choice B is incorrect because a scoop stretcher does not provide sufficient immobilization for thoracic spine injuries. Choice C is incorrect as spinal cord injury below T10 can still affect bowel and bladder function due to the autonomic nervous system involvement. Choice D is incorrect because hyperflexion fractures in the upper thoracic spine are typically stable, not inherently unstable.

Correct Answer: A

Rationale: The correct answer is A because DPL (Diagnostic Peritoneal Lavage) is primarily used to detect intra-abdominal bleeding. Subcapsular hematoma of the spleen is a type of intra-abdominal bleeding that can be detected using DPL due to the accumulation of blood in the spleen. Liver laceration, bowel injury, and pancreatic injury may also lead to intra-abdominal bleeding, but they are not specific to the purpose of DPL, which is to detect bleeding. Therefore, A is the correct choice as it directly relates to the main objective of using DPL.
