The correct answer is B. Ventricular tachycardia only.
Key Concept: Shockable Rhythms and Pulse Presence
The two primary shockable rhythms are:
Ventricular fibrillation (VF)
Ventricular tachycardia (VT)
Ventricular Fibrillation (VF):
Chaotic, disorganized electrical activity
No effective cardiac output
Always pulseless
NREMT-aligned reference:
"Ventricular fibrillation results in no pulse due to ineffective quivering of the ventricles." Ventricular Tachycardia (VT):
Rapid, organized ventricular rhythm
May be:
Pulseless VT (cardiac arrest)
Perfusing VT (with a pulse)
NREMT-aligned reference:
"Ventricular tachycardia may present with or without a pulse."
Why B is correct:
Only ventricular tachycardia can sometimes produce a pulse
VF never produces a pulse
Why the other options are incorrect:
A). VF only # Incorrect; VF is always pulseless
C). Both # Incorrect; VF cannot produce a pulse
D). Neither # Incorrect; VT can produce a pulse
Exact Extracts (NREMT/AHA-aligned references):
"Shockable rhythms include ventricular fibrillation and pulseless ventricular tachycardia."
"Ventricular tachycardia may be with or without a pulse."
"Ventricular fibrillation produces no cardiac output."
Clinical Priority Summary:
Among shockable rhythms, only ventricular tachycardia can still produce a pulse, making B the correct answer.

The correct answer is D because stridor and erythema in this context strongly indicate anaphylaxis with upper airway involvement . Stridor is a sign of airway swelling , which can rapidly lead to complete airway obstruction.
NREMT-aligned EMT guidelines emphasize that epinephrine is the first-line treatment for anaphylaxis , as it rapidly reduces airway swelling (vasoconstriction), improves breathing (bronchodilation), and supports circulation. Early administration is critical to prevent deterioration.
While oxygen is important, epinephrine takes priority because it directly treats the underlying life- threatening allergic reaction.

Personal injury prevention supplies are designed to protect EMS providers from physical injuries, rather than infection.
Option C (Pair of leather gloves) is correct because leather gloves protect against cuts, abrasions, and puncture injuries during rescue operations such as vehicle extrication.
Option D (N95 respirator) is personal protective equipment (PPE) for infection control, not injury prevention.
Option A and B are related to biohazard handling and decontamination.
NREMT differentiates PPE from injury-prevention equipment to ensure proper risk management.

The correct answer is B. Place padding under the torso only.
Key Pediatric Anatomical Difference:
Children (especially under ~8 years old) have a larger occiput (back of the head) relative to their body. When lying flat on a backboard:
The head is naturally pushed forward (flexed position)
This can compromise the airway and spinal alignment
Correct Technique:
To achieve a neutral airway and spinal alignment:
Padding is placed under the torso (shoulders/back)
This raises the body and allows the head to fall into a neutral position NREMT-aligned guidance states:
"Due to a larger occiput, pediatric patients may require padding under the torso to maintain a neutral airway."
"Avoid placing padding under the head alone, as this worsens flexion."
Why the other options are incorrect:
A). Padding under the head only# Worsens neck flexion, potentially compromising airway C). Padding under both head and torso# Unnecessary and may misalign the spine D). No padding# Leaves the head in a flexed, non-neutral position Exact Extracts (NREMT-aligned EMT educational references):
"Children have a proportionally larger head, causing flexion when supine."
"Padding under the torso helps achieve neutral alignment."
"Maintain neutral in-line stabilization during immobilization."
Clinical Priority Summary:
Because pediatric patients naturally fall into neck flexion on a backboard, placing padding under the torso restores neutral alignment, making B the correct answer.

The symptoms described are classic for a stroke (CVA). Additional hallmark findings include:
Arm drift (motor weakness or hemiparesis)
Facial droop (Cranial nerve VII involvement)
Slurred speech (dysarthria or aphasia)
These form the basis of prehospital stroke assessment tools like FAST:
Face drooping
Arm weakness
Speech difficulty
Time to call 911
Miosis (pupil constriction) and tremors are not associated with stroke in EMS context. Syncope is an isolated event and not a reliable CVA symptom.
