NEW QUESTION # 199
What patient conditions have an indication for the use of a CPAP device? Select the three answer options that are correct.
Answer: B,C,F
Explanation:
Comprehensive and Detailed Explanation (Based on NREMT standards):
Continuous Positive Airway Pressure (CPAP) is used in patients with moderate to severe respiratory distress who are conscious and able to maintain their airway. NREMT guidelines identify specific respiratory conditions where CPAP improves oxygenation and ventilation.
Option A (Chronic bronchitis) is correct because CPAP helps overcome airway collapse and improves gas exchange in COPD patients.
Option B (Pulmonary edema) is correct because CPAP reduces preload and afterload while forcing fluid out of alveoli, improving oxygenation.
Option C (Acute bronchospasms) is correct because CPAP helps splint open airways and reduce work of breathing.
Option D is incorrect because CPAP is not used for isolated myocardial infarction without respiratory failure.
Option E is contraindicated because positive pressure can worsen a pneumothorax.
Option F is contraindicated due to airway burns and potential inhalation injury.
NREMT stresses proper patient selection to prevent CPAP-related complications.

A 42-year-old male states, "I can't breathe" after being shot in his upper thigh. Bystanders have applied direct pressure to his thigh and the bleeding is controlled. You should first
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Thepatient's complaint of difficulty breathingis anairway/breathing issueand takes precedence over a controlled extremity bleed. The first action is toadminister oxygenand evaluate respiratory effort.
Though reassessing the wound is important,oxygenation is the prioritywhen airway compromise or respiratory distress is present. Tourniquets are foruncontrolled bleeding, which is not the case here.

NEW QUESTION # 201
A 31-year-old patient has an open femur fracture and an unstable pelvis after falling 15 feet. They are conscious and responsive to verbal stimuli. The vital signs are BP 86/42, P 136, R 24, and SpO# 92% on room air. The patient has which of the following types of shock? Select the two correct options.
Answer: B,D
Explanation:
This is a classic presentation of hypovolemic shock due to traumatic blood loss (open femur fracture, pelvic instability). Indicators include:
* Low BP (86/42) = hypotension
* High pulse (P 136) = compensation
* Mental status decline (responsive only to voice) = indicates decompensated shock Obstructive and distributive shock are not applicable. Compensated shock would show normal BP and alert mental status.

NEW QUESTION # 202
A 6-year-old female rode her bicycle into a parked car. She is in moderate respiratory distress and you palpate subcutaneous emphysema. Of the following, what is the most important management for her?
Answer: B
Explanation:
Subcutaneous emphysema following blunt chest trauma strongly suggests air leaking from the lung into surrounding tissues, often associated with pneumothorax. NREMT trauma priorities stress that airway and breathing take precedence over all other interventions.
Option D is correct because the child is already in moderate respiratory distress, indicating inadequate ventilation. Assisting ventilations with a BVM ensures oxygen delivery and adequate tidal volume while preparing for rapid transport.
Option A is important but does not address the immediate life threat.
Option B may help with pain or flail segments but does not correct ventilation.
Option C is no longer routinely indicated and does not address breathing.
NREMT emphasizes correcting life-threatening airway and breathing problems before movement or transport.
NEW QUESTION # 203
Following insertion of an oropharyngeal airway in an unresponsive 1-year-old male, he develops cyanosis and bradycardia. You should
Answer: C
Explanation:
The correct answer is A. Remove the airway and ventilate him.
In pediatric patients, improper placement or incorrect sizing of an oropharyngeal airway (OPA) can cause:
* Airway obstruction instead of opening
* Worsening hypoxia
* Leading to cyanosis and bradycardia
* The patient's cyanosis (low oxygen) and bradycardia (late hypoxia sign) indicate that the airway intervention has failed or worsened the situation.
* Immediate action is to:
* Remove the OPA
* Provide effective ventilations with BVM
* B. Continue ventilation with the airway in place # Incorrect because the airway is likely malpositioned or obstructing airflow
* C. Increase ventilation rate to 40-60 # Excessive and inappropriate; does not correct obstruction
* D. Start CPR if HR < 100 # In pediatrics, CPR begins if HR < 60 with poor perfusion, not < 100
* "If an airway adjunct worsens ventilation, it should be removed immediately."
* "Bradycardia in infants is a sign of hypoxia."
* "Ensure adequate ventilation before initiating compressions."
