NEW QUESTION # 32
A 38-year-old patient is dyspneic and has facial swelling after eating at a restaurant. What should the EMT do first?
Answer: C
Explanation:
The correct answer is C. Administer epinephrine.
This patient is presenting with classic signs of anaphylaxis, a life-threatening allergic reaction:
* Dyspnea (respiratory distress)
* Facial swelling (angioedema)
* Recent exposure to a likely allergen (food)
Why C is correct (Epinephrine):
Epinephrine is the first-line, life-saving treatment for anaphylaxis. It works by:
* Dilating bronchioles (improving breathing)
* Constricting blood vessels (improving blood pressure)
* Reducing airway swelling
NREMT-aligned guidelines state:
* "Administer epinephrine immediately in patients with signs of anaphylaxis."
* "Do not delay epinephrine administration in life-threatening allergic reactions." Why the other options are incorrect:
* A. Provide oxygen: Important, but not the priority over epinephrine in anaphylaxis.
* B. Initiate rapid transport: Necessary, but after immediate life-saving intervention.
* D. Obtain vital signs: Should not delay treatment in a critical patient.
Key Concept:
* In anaphylaxis, epinephrine is the first and most critical intervention.
* Delays in administration significantly increase mortality risk.
Exact Extracts:
* "Epinephrine is the drug of choice for anaphylaxis."
* "Immediate administration is critical in respiratory distress with allergic reactions."
* "Airway swelling and bronchoconstriction must be rapidly treated."

NEW QUESTION # 33
An Emergency Medical Responder is ventilating an apneic adult using a BVM. He is forcefully delivering each ventilation in less than 1 second. You should
Answer: C
Explanation:
NREMT guidelines specify that adult ventilations with a BVM should be delivered over approximately 1 second, just enough to see visible chest rise. Forceful, rapid ventilations increase the risk of gastric inflation, aspiration, barotrauma, and hypotension.
Option B is correct because slowing the rate and reducing force improves ventilation effectiveness and patient safety.
Option A may be important, but the primary error described is ventilation speed.
Option C is inappropriate for an apneic patient.
Option D is only indicated if the patient is pulseless.
NREMT emphasizes controlled, gentle ventilations to minimize complications.
NEW QUESTION # 34
A 15-year-old patient is unresponsive following an assault. The patient has a stab wound on the chest, which is gurgling. The vital signs are BP 76/48 mmHg, P 146/min, R 26/min, and SpO# 90% on room air.
Which of the following types of shock is the most likely cause of the patient's presentation?
Answer: C
Explanation:
Comprehensive and Detailed Explanation (Based on NREMT standards):
This patient has signs of penetrating chest trauma, severe hypotension, tachycardia, and respiratory distress.
A gurgling chest wound suggests an open pneumothorax, which can progress to tension pneumothorax.
Option C (Obstructive shock) is correct because air trapped in the chest can compress the heart and great vessels, preventing adequate cardiac output.
Option A is less likely because although blood loss may be present, the chest injury suggests impaired circulation due to pressure.
Option B involves pump failure, not trauma-related compression.
Option D involves abnormal vessel dilation, not mechanical obstruction.
NREMT emphasizes rapid recognition of obstructive shock and immediate intervention with occlusive dressings and rapid transport.
NEW QUESTION # 35
What sign is the best indication that an 8-year-old is in hypovolemic shock?
Answer: B
Explanation:
In pediatric patients, NREMT emphasizes that hypotension is a late and ominous sign of shock. Children compensate well and may maintain blood pressure until shock is severe.
Option C (Tachypnea) is the earliest and most reliable indicator of hypovolemic shock in children. Increased respiratory rate reflects metabolic acidosis and compensatory mechanisms for poor perfusion.
Option A may be present but is less specific.
Option B is a very late finding.
Option D indicates decompensated shock and impending cardiovascular collapse.
NREMT stresses early recognition of shock through subtle signs such as tachypnea and tachycardia.
NEW QUESTION # 36
A 67-year-old patient is short of breath and sitting in a tripod position. The patient has bilateral wheezing, is coughing up green sputum, and is breathing through pursed lips. The vital signs are BP 122/90 mmHg, P 108
/min, R 28/min, and SpO# 93% on home oxygen. Which of the following conditions best explains this patient
' s presentation?
Answer: D
Explanation:
The correct answer is D. Chronic obstructive pulmonary disease (COPD).
Key findings in this scenario:
* Tripod position # classic for COPD patients trying to improve ventilation
* Pursed-lip breathing # hallmark COPD compensation technique
* Bilateral wheezing # indicates lower airway obstruction
* Productive cough with sputum # common in chronic bronchitis (COPD subtype)
* Use of home oxygen # suggests chronic respiratory disease
Why COPD is correct:
COPD (including chronic bronchitis and emphysema) commonly presents with:
* Wheezing
* Productive cough
* Pursed-lip breathing
* Tripod positioning
* Chronic oxygen use
NREMT-aligned references state:
* "COPD patients often present with wheezing, productive cough, and use of accessory muscles."
* "Pursed-lip breathing and tripod position are characteristic findings." Why the other options are incorrect:
* A. PneumoniaTypically presents with fever, localized crackles, not pursed-lip breathing or tripod positioning
* B. Pulmonary embolusUsually presents with sudden dyspnea, clear lungs, and no productive cough
* C. Congestive heart failurePresents with crackles, pulmonary edema, and possibly pink frothy sputum, not wheezing with green sputum Exact Extracts (NREMT-aligned EMT educational references):
* "COPD patients may sit in a tripod position and use pursed-lip breathing."
* "Wheezing and productive cough are common findings."
* "Many patients require home oxygen therapy."
Clinical Priority Summary:
The combination of tripod position, wheezing, productive cough, pursed-lip breathing, and home oxygen use clearly indicates COPD, making D the correct answer.
