What components are necessary to maintain adequate perfusion? Select the three correct options.
A. High alveolar pressure
B. Patent airway
C. Sufficient blood volume
D. Intact microcirculation
E. Hypoxic drive
F. Low ventilation-perfusion ratio
正解：B、C、D
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Perfusionrefers to delivery of oxygen and nutrients to tissues. It depends on three essential components:
* Patent airway: Ensures oxygen reaches lungs
* Intact microcirculation: Capillary-level exchange must function
* Sufficient blood volume: Maintains blood pressure and oxygen transport Hypoxic drive relates toCOPD physiology, not perfusion.High alveolar pressure(like from CPAP) may impede venous return, and alow ventilation-perfusion ratiomeans poor oxygenation efficiency, which negatively affects perfusion.

質問 # 63
In order for a plaintiff to recover damages in a lawsuit against an EMT, there must be a duty to perform, breach of duty, damage, and
A. Abandonment
B. Contributory neglect
C. Proximate causation
D. Malfeasance
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
To establishnegligence, four legal elements must be proven:
* Duty to act- a legal obligation to provide care.
* Breach of duty- failing to meet the standard of care.
* Damages- harm occurred.
* Proximate causation- the breach directly caused the damage.
"Proximate causation" means the EMT's action or inaction is closely linked to the harm suffered by the patient.

質問 # 64
A 65-year-old patient with a history of angina reports chest pain and shortness of breath after playing golf. The patient stated the pain began one hour ago and has not stopped with rest. The vital signs are BP 86/64, P 112, R 22, and SpO# 89% on room air. Which of the following actions should the EMT do next?
A. Give nitroglycerin
B. Provide nebulized albuterol
C. Administer CPAP
D. Obtain a 12-lead ECG
正解：D
解説：
Comprehensive and Detailed Explanation From Exact Extract:
This is ahigh-risk cardiac eventdue to unstable angina or possiblemyocardial infarction. The EMT should:
* Administer oxygenif SpO# is <94%
* Avoid nitroglycerinif systolic BP is <90 mmHg
* Obtain a 12-lead ECGto identify ST-elevation MI (STEMI) and transmit it if trained and authorized CPAP is indicated forpulmonary edema, and albuterol is forbronchospasm, neither of which applies here.

質問 # 65
A 12-year-old male suffered helmet-to-helmet contact while playing football. A bystander states, "He passed out for several seconds, then walked off the field under his own power." He is now unresponsive, and his vital signs are BP 180/110, P 90, and R 6. You should suspect
A. Subarachnoid hemorrhage
B. Intracerebral hematoma
C. Epidural hematoma
D. Subdural hemorrhage
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Anepidural hematomaclassically presents with a"lucid interval"- a brief period of regained consciousness following head trauma, followed by rapid deterioration. This is due to arterial bleeding, often from themiddle meningeal artery, leading to increasing intracranial pressure.
Signs include:
* High blood pressure
* Decreasing respiratory rate
* Altered LOC or unresponsiveness
Subdural hemorrhages are slower venous bleeds, common in elderly patients. Subarachnoid hemorrhage often presents with "worst headache of life." Intracerebral bleeds are less commonly linked to lucid intervals.

質問 # 66
A 27-year-old patient reports trouble breathing after being struck by a car. Which of the following findings are indicative of a possible chest wall injury? Select the three answer options that are correct.
A. Epigastric distension
B. Clavicle deformity
C. Jugular vein distention
D. Subcutaneous emphysema
E. Occipital depression
F. Unequal rise and fall
正解：B、D、F
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Clavicle deformity suggests potential rib or thoracic trauma. Unequal chest rise may indicate a flail segment, pneumothorax, or hemothorax. Subcutaneous emphysema, the presence of air under the skin, is a classic finding in pneumothorax or tracheobronchial injury.
Occipital depression is not chest related; epigastric distension is a GI symptom; and jugular vein distention would suggest tension pneumothorax or cardiac tamponade, which are more advanced complications.
