質問 # 188
A 3-year-old patient has drooling and stridor. The vital signs are BP 82/40, P 132, R 34, SpO# 94%, and T
102.4°F (39.1°C). Which of the following interventions should the EMT perform?
正解：A
解説：
The correct answer is D. Apply humidified oxygen.
This patient presentation is highly suggestive of epiglottitis, a life-threatening upper airway infection commonly seen in pediatric patients.
Key findings:
* Drooling # inability to swallow secretions
* Stridor # upper airway obstruction
* Fever (102.4°F) # infection
* Anxiety and tachycardia # respiratory distress
Why D is correct:
* The priority is to maintain airway patency without agitating the child.
* Humidified oxygen helps improve oxygenation while minimizing airway irritation.
* It is the safest initial intervention in suspected epiglottitis.
Why the other options are incorrect:
* A. Visualize the airway # Can trigger complete airway obstruction due to swelling
* B. Suction posterior pharynx # May stimulate gag reflex and worsen obstruction
* C. Insert oropharyngeal airway # Contraindicated in conscious or semi-conscious patients and may cause airway collapse Exact Extracts:
* "Do not attempt to visualize the airway in suspected epiglottitis."
* "Avoid any procedure that may agitate the child and cause airway obstruction."
* "Provide humidified oxygen and transport promptly."

質問 # 189
A 12-year-old male suffered helmet-to-helmet contact while playing football. A bystander states, "He passed out for several seconds, then walked off the field under his own power." He is now unresponsive, and his vital signs are BP 180/110, P 90, and R 6. You should suspect
正解：D
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Anepidural hematomaclassically presents with a"lucid interval"- a brief period of regained consciousness following head trauma, followed by rapid deterioration. This is due to arterial bleeding, often from themiddle meningeal artery, leading to increasing intracranial pressure.
Signs include:
* High blood pressure
* Decreasing respiratory rate
* Altered LOC or unresponsiveness
Subdural hemorrhages are slower venous bleeds, common in elderly patients. Subarachnoid hemorrhage often presents with "worst headache of life." Intracerebral bleeds are less commonly linked to lucid intervals.

質問 # 190
Which of the following are signs or symptoms of a hypertensive emergency? Select the two answer options that are correct.
正解：A、B
解説：
For this one, focus on what makes hypertension an emergency rather than just a high blood pressure reading:
evidence of acute end-organ involvement . Two important clues are headache from possible neurologic involvement and orthopnea from possible acute pulmonary edema/heart failure . Authoritative references on hypertensive emergency describe it as severe hypertension with target-organ damage such as pulmonary edema and neurologic symptoms, and headache is a common presenting complaint while orthopnea points to pulmonary congestion. ( NCBI ) So in an EMT testing context, the best two choices are B. Orthopnea and E. Headache because they fit the pattern of a hypertensive crisis with serious organ-system effects, not just isolated elevated blood pressure. ( NCBI )
質問 # 191
What finding indicates that a mild airway obstruction has become a severe obstruction?
正解：B
解説：
NREMT distinguishes mild versus severe airway obstruction primarily by the patient's ability to move air. In a mild obstruction, the patient can cough forcefully, speak, and exchange air. A severe obstruction occurs when airflow is critically impaired.
Option A (Ineffective cough) is the key indicator that a mild obstruction has progressed to a severe one. An ineffective or silent cough means the patient can no longer generate enough airflow to clear the obstruction, placing them at imminent risk of hypoxia and cardiac arrest.
Option B is a late sign of hypoxia but does not define severity of obstruction.
Option C is not specific to airway obstruction severity.
Option D indicates a mild obstruction, not severe.
NREMT teaches that once a cough becomes ineffective, immediate airway intervention is required.
質問 # 192
You are transporting a febrile 62-year-old male who has a cough and body aches. His vital signs are BP 136
/80, P 100, R 16, and his SpO# is 99% on room air. You should first:
正解：A
解説：
The correct answer is A. Place a surgical mask on him.
This question focuses on infection control and standard precautions, which fall under EMS Operations in NREMT content.
The patient presents with:
* Fever
* Cough
* Body aches
These are classic signs of a respiratory infectious illness, and EMS providers must immediately take steps to prevent transmission.
According to NREMT-aligned infection control principles, the first priority when dealing with a potentially infectious respiratory patient is source control, which means placing a surgical mask on the patient to limit the spread of droplets.
Why A is correct:
* A surgical mask on the patient reduces transmission of respiratory droplets.
* This is considered an immediate and appropriate standard precaution.
Why the other options are incorrect:
* B. Administer oxygen: The patient's SpO# is 99% on room air, indicating adequate oxygenation.
NREMT guidelines emphasize that oxygen should be administered based on clinical need, not routinely.
* C. Place an N95 mask on him: N95 respirators are intended for healthcare providers, not patients. The patient should receive a surgical mask, not an N95.
* D. Transport him in the recovery position: This position is used for patients with decreased level of consciousness or risk of airway compromise, which is not indicated here.
Exact Extract (EMT-aligned educational content):
* EMS providers must use standard precautions and take appropriate measures to prevent disease transmission.
* For patients with suspected respiratory infections, placing a surgical mask on the patient helps prevent the spread of droplets.
* Oxygen should be administered only when there are signs of hypoxia or respiratory distress, not when oxygen saturation is normal.
