NEW QUESTION # 145
An 83-year-old patient is unresponsive and lying on the floor. The patient has a large bruise and laceration on the forehead. The patient's vital signs are BP 90/60, P 126, and R 0. Which of the following conditions should the EMT most suspect?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Givenfall with head traumaandabsent respirations, the most concerning cause isspinal injury, particularly acervical spine fracture. Ahigh cervical injury (C1-C4)canparalyze the diaphragm, leading toapnea despite a beating heart.
Brain herniation can also depress respirations but often presents withunequal pupils,posturing, andCushing' s triad(not described here).Commotio cordisis sudden cardiac arrest from blunt chest trauma (not head).
Open pneumothoraxaffects chest mechanics, not directly linked here.

NEW QUESTION # 146
A 40-year-old patient is unresponsive following an electrical injury. What is the most likely cause of the patient's mental status?
Answer: B
Explanation:
Comprehensive and Detailed Explanation (Based on NREMT standards):
Electrical injuries commonly disrupt the heart's electrical conduction system. NREMT teaching emphasizes that cardiac dysrhythmias are the leading cause of unresponsiveness following electrical exposure, even when external burns appear minor.
Option A is correct because electrical current can induce lethal dysrhythmias such as ventricular fibrillation or asystole, resulting in sudden loss of consciousness.
Option B is incorrect because internal bleeding is not a primary consequence of electrical injury.
Option C may occur but does not typically cause immediate unresponsiveness.
Option D is less likely than cardiac involvement and is not the most common cause.
NREMT stresses continuous cardiac monitoring and rapid transport for all electrical injury patients due to the high risk of sudden cardiac arrest.
NEW QUESTION # 147
When using START triage, which of the following patients would the EMT consider to be a red tag? Select the two answer options that are correct.
Answer: A,E
Explanation:
The correct answers are A and C.
START triage categorizes patients based on respirations, perfusion, and mental status (RPM). A red tag (Immediate) is assigned to patients who have life-threatening conditions that can be rapidly treated.
START Criteria for Red Tag (Immediate):
Respirations > 30/min
Capillary refill > 2 seconds or no radial pulse
Unable to follow commands
Option A: Correct (Red Tag)
The child is unconscious (cannot follow commands) # immediate red classification Capillary refill is 4 seconds ( > 2 seconds) # poor perfusion Meets two red criteria Option C: Correct (Red Tag) Normal respirations (acceptable), BUT Capillary refill is 5 seconds ( > 2 seconds) # indicates poor perfusion/shock This alone qualifies for red tag Why the other options are incorrect:
B). Walking patient # Automatically categorized as green (minor) regardless of other findings D). No breathing after airway repositioning # Classified as black (deceased/expectant), not red E). Cannot walk but follows commands, normal breathing, normal pulse # Yellow (delayed) Exact Extracts:
"Patients who can walk are tagged as minor (green)."
"If capillary refill is greater than 2 seconds, tag the patient as immediate (red)."
"If the patient cannot follow simple commands, tag as immediate."
"If the patient is not breathing after airway repositioning, tag as deceased (black)." References:

NEW QUESTION # 148
What characteristics of the pediatric airway are different from the adult airway?
Answer: C
Explanation:
Compared to adults, pediatric patients have:
* A proportionately larger tongue, which increases the risk of airway obstruction
* A larger occiput, which causes natural neck flexion when lying supine, potentially occluding the airway This anatomical difference is why EMS providers often use a shoulder roll instead of a head tilt to maintain a neutral airway in infants and toddlers.

NEW QUESTION # 149
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: A,B
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."
