NEW QUESTION # 159
A 48-year-old patient was shot in their left shoulder. The EMT observes bright red blood pulsating from the wound. Which of the following actions should the EMT perform first?
Answer: D
Explanation:
The correct answer is B. Apply direct pressure.
This patient is experiencing severe arterial bleeding, as indicated by:
Bright red blood
Pulsating flow
Direct pressure is the first-line treatment for external bleeding, including arterial hemorrhage.
It is the fastest and most effective immediate intervention to control bleeding.
EMT protocols emphasize controlling life-threatening bleeding before other interventions.
A). Place a tourniquet # Appropriate if direct pressure fails or bleeding is uncontrollable, but not the first step C). Sling and swathe # Used for immobilization, not hemorrhage control D). Oxygen # Important, but bleeding control takes priority (circulation first in trauma) Exact Extracts:
"Control external bleeding with direct pressure as the first step."
"Arterial bleeding is characterized by bright red, pulsating blood."
"Tourniquets are used when direct pressure fails to control severe bleeding." References:

NEW QUESTION # 160
A patient is having an asthmatic attack. The EMT receives orders from medical control to assist with the patient's inhaler. What are the expected side effects of this medication? Select the three correct options.
Answer: A,C,F
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Albuterol, a commonbeta-2 adrenergic agonistused in inhalers, stimulates bronchial smooth muscle relaxation. However, stimulation of beta receptors can also produce systemic effects such as:
* Tachycardia(due to beta-1 cross-reactivity)
* Nervousness(from central stimulation)
* Coughing(a local airway response)
Confusion and drowsiness are not typical side effects of beta-agonists. Hypotension is rare unless severe overdose occurs.

NEW QUESTION # 161
Which of the following is a potential complication of positive pressure ventilation?
Answer: B
Explanation:
Positive pressure ventilation (PPV) forces air into the lungs under pressure rather than relying on negative intrathoracic pressure. NREMT education emphasizes that while PPV is lifesaving, it carries important risks- most notably decreased venous return to the heart.
Option C (Profound hypotension) is correct because increased intrathoracic pressure reduces preload by compressing the vena cava, which can significantly lower cardiac output and blood pressure. This effect is especially pronounced in hypovolemic or trauma patients.
Option A is incorrect because diaphragmatic movement is not a complication.
Option B is unrelated to ventilation.
Option D describes a ventilation parameter, not a complication.
NREMT stresses careful ventilation rates and volumes to avoid hypotension, gastric inflation, and barotrauma.
NEW QUESTION # 162
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: C,D
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 # 163
While responding to an emergency, a car is tailgating the ambulance. Which of the following actions should the EMT take?
Answer: B
Explanation:
In situations where a vehicle is tailgating an emergency unit, tapping the brakes briefly is a standard defensive driving maneuver to alert the driver behind to increase distance. It is less risky than slowing dramatically or pulling over, which could endanger crew or delay response.
Speeding up could reduce your reaction window or increase accident risk. EMS operators must follow safe driving practices per NFPA 1002 and DOT Emergency Vehicle Operation Guidelines.
