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. These leads correspond to the inferior part of the heart supplied by the right coronary artery. The ST elevation in these leads suggests acute injury or infarction in this area. The other choices are incorrect because: A: Lateral wall is typically indicated by ST elevation in Leads I, aVL, V5-V6. C: Anterior wall is typically indicated by ST elevation in Leads V1-V4. D: Septal wall is typically indicated by ST elevation in Leads V1-V2.

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 is the failure to exercise the standard of care that a reasonably prudent person would have in a similar situation. 2. In this scenario, the paramedic in charge failed to ensure the equipment was adequately charged or had backup batteries, leading to the device shutting off during a critical moment. 3. This failure to provide proper equipment falls below the standard of care expected in the field of emergency medical services. 4. As a result, the patient's death could be attributed to the paramedic's negligence in ensuring equipment readiness. Summary: A: Manslaughter charges require a higher level of intent and causation, not applicable here. C: Battery charges refer to physical harm, not applicable in this context. D: Defamation charges involve false statements damaging a person's reputation, not relevant to the situation described.

Correct Answer: D

Rationale: The correct answer is D because the absolute volume of blood loss required to produce shock in children is not the same as in adults. Children have a smaller blood volume compared to adults, so even a smaller amount of blood loss can lead to shock. This is due to their smaller size and lower total blood volume. A: Vital signs are age-related - True, children have different normal vital signs compared to adults. B: Children have greater physiologic reserves than do adults - True, children have more reserves to compensate for shock. C: Tachycardia is the primary physiologic response to hypovolemia - True, tachycardia is a common response to maintain perfusion in hypovolemic shock.

Correct Answer: A

Rationale: The correct answer is A: Log-rolling may be destabilizing to fractures from T12 to L1. Log-rolling involves moving a patient as a unit to prevent further spinal cord injury. In patients with thoracic spine injuries at T12 to L1, log-rolling can cause disruption or misalignment of the fractured vertebrae, leading to potential neurological damage or increased spinal instability. Therefore, avoiding log-rolling in these cases is crucial to prevent further harm. Choice B is incorrect because the scoop stretcher may not provide adequate immobilization for thoracic spine injuries due to its limitations in maintaining proper spinal alignment. Choice C is incorrect as spinal cord injuries below T10 can affect bowel and bladder function due to the involvement of the sacral segments. Choice D is incorrect because hyperflexion fractures in the upper thoracic spine are generally considered stable, not inherently unstable.

Correct Answer: A

Rationale: The correct answer is A: "Subcapsular hematoma of the spleen" because DPL (Diagnostic Peritoneal Lavage) is a diagnostic procedure used to assess for intra-abdominal injuries, particularly to organs like the liver, bowel, and pancreas. A subcapsular hematoma of the spleen is an injury specific to the spleen, which is not directly evaluated by DPL. The other choices (B: Liver laceration, C: Bowel injury, D: Pancreatic injury) are all potential injuries that can be detected by DPL due to their location within the abdominal cavity and the presence of free intra-abdominal fluid.
