NEW QUESTION # 102
An 86-year-old patient involved in a motor vehicle collision struck a knee on the dashboard. What injuries are most associated with the knee impacting the dashboard? Select the two answer options that are correct.
Answer: B,E
Explanation:
The correct answers are B. Femur fracture and E. Posterior hip dislocation.
This mechanism is classically known as a "dashboard injury", where the knee strikes the dashboard during a motor vehicle collision. The force is transmitted along the femur toward the hip.
Why B is correct (Femur fracture):
The force applied to the knee travels up the femur, which can result in:
* Femoral shaft fractures
* Significant internal bleeding
NREMT trauma guidance states:
* "High-energy impacts to the lower extremities can result in femur fractures." Why E is correct (Posterior hip dislocation):
Dashboard injuries commonly cause:
* Posterior displacement of the femoral head from the acetabulum
* This occurs when the femur is driven backward while the hip is flexed NREMT-aligned content:
* "A blow to the knee in a seated position can result in posterior hip dislocation." Why the other options are incorrect:
* A. Tibia fracture: More commonly associated with direct lower leg trauma, not classic dashboard mechanism.
* C. Ruptured peritoneum: Not a typical injury from this mechanism.
* D. Rupture of the bladder: More associated with pelvic fractures, not isolated dashboard knee impact.
Exact Extracts:
* "A dashboard injury can transmit force up the femur causing hip dislocation."
* "Posterior hip dislocation is commonly associated with knee impact in MVCs."
* "Femur fractures are common in high-energy trauma."

NEW QUESTION # 103
A 60-year-old has severe shortness of breath. Audible wheezing is present. The patient has a history of COPD, asthma, and diabetes with prescribed medications. The vital signs are BP 138/80, P 110, R 30, and SpO# 89% on room air. What actions should the EMT take? Select the two answer options that are correct.
Answer: A,C
Explanation:
The correct answers are B. Apply continuous positive airway pressure (CPAP) and D. Administer a beta-2 agonist.
This patient is in moderate to severe respiratory distress with:
* Tachypnea (R 30)
* Hypoxia (SpO# 89%)
* Wheezing # indicates bronchoconstriction (asthma/COPD exacerbation)
Why B is correct (CPAP):
* CPAP helps keep alveoli open, improves oxygenation, and reduces work of breathing.
* It is indicated in patients who are awake, breathing, and in respiratory distress with hypoxia.
* Especially beneficial in COPD exacerbations.
Why D is correct (Beta-2 agonist):
* Beta-2 agonists (e.g., albuterol) relax bronchial smooth muscle, relieving wheezing and bronchospasm.
* This directly treats the underlying problem in asthma/COPD exacerbation.
Why the other options are incorrect:
* A. 3 LPM nasal cannula # Too low for significant hypoxia (SpO# 89%); patient needs more aggressive support
* C. Recovery position # Used for unconscious patients, not alert patients in respiratory distress
* E. Rescue breathing # Indicated for inadequate respirations, but this patient is breathing (though rapid) Exact Extracts:
* "CPAP is indicated for patients with respiratory distress who are breathing spontaneously."
* "Beta-agonists are used to relieve bronchospasm in asthma and COPD."
* "Patients with wheezing benefit from bronchodilator therapy."

NEW QUESTION # 104
Which of the following elements proves tort negligence in a court of law?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The legal concept oftort negligencein EMS requires the plaintiff to establish four elements:
* Duty to act
* Breach of that duty
* Damages (harm caused)
* Causation- a direct link between the EMT's action/inaction and the harm caused Causation(often termed "proximate cause") is the essential element that connects the EMT's breach to the patient's injury or outcome. Abandonment, assault, and false imprisonment are otherintentional torts, but not core elements of proving negligence.

NEW QUESTION # 105
A patient is experiencing acute coronary syndrome but is not hypoxemic. Which of the following results could come from oxygen administration? Select the two answer options that are correct.
Answer: A,D
Explanation:
The correct answers are C. Increased tissue damage and E. Coronary artery vasoconstriction.
In patients with acute coronary syndrome (ACS) who are NOT hypoxemic, routine oxygen administration is no longer recommended because it may actually be harmful.
Key pathophysiology:
1. Coronary Artery Vasoconstriction (E):
High concentrations of oxygen can cause vasoconstriction of coronary arteries, which reduces blood flow to already ischemic heart tissue.
"Supplemental oxygen in non-hypoxemic patients may cause coronary vasoconstriction."
2. Increased Tissue Damage (C):
Excess oxygen can lead to oxidative stress and worsen ischemic injury, potentially increasing infarct size or tissue damage.
"Hyperoxia may increase oxidative injury and worsen myocardial damage." Why the other options are incorrect:
A). Reduced mortality: Evidence does not support mortality benefit in non-hypoxemic ACS patients.
B). Resolution of chest pain: Oxygen does not reliably relieve ischemic chest pain unless hypoxia is present.
D). Reduction in infarction size: Studies show no benefit and possible harm.
NREMT/AHA-aligned guidance emphasizes:
"Administer oxygen only if SpO# is less than 94% or if the patient is hypoxic." Routine oxygen in normoxic patients is not recommended and may be harmful.
Exact Extracts (NREMT/AHA-aligned references):
"Avoid routine oxygen use in patients with normal oxygen saturation."
"Hyperoxia can cause coronary vasoconstriction."
"Excess oxygen may worsen myocardial injury."
Clinical Priority Summary:
In non-hypoxemic ACS patients, oxygen can cause harm rather than benefit, specifically vasoconstriction and increased tissue damage, making C and E correct.

NEW QUESTION # 106
A 58-year-old patient reports chest pain and difficulty breathing after missing their last three hemodialysis treatments. Which of the following signs and symptoms should the EMT suspect to find?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Missing dialysis leads tofluid overload, causing:
* Pulmonary edema, evident bycrackleson auscultation
* Dyspnea and chest discomfort
Bradycardia is less likely; patients more often present withtachycardiadue to volume stress. Fever would suggest infection (not stated here), and hypotension can occur later, but hypertension is more common in early fluid overload.
