A patient presents with a tension pneumothorax. Which clinical finding is most specific to this condition?
Answer: Tracheal deviation away from the affected side
Tracheal deviation away from the affected side is a classic late sign of tension pneumothorax caused by mediastinal shift from accumulating pressure.
When using a bag-valve-mask device on an adult patient, what tidal volume should you target to avoid gastric insufflation?
Answer: 500–600 mL delivered over 1 second
A tidal volume of 500–600 mL over about 1 second is sufficient for oxygenation and minimizes the risk of gastric insufflation and aspiration.
Which of the following is the correct initial dose of epinephrine for anaphylaxis in an adult?
Answer: 0.3–0.5 mg IM (1:1,000) into the anterolateral thigh
The standard adult anaphylaxis dose is 0.3–0.5 mg of 1:1,000 epinephrine injected intramuscularly into the anterolateral thigh for fastest absorption.
A 68-year-old male has a blood pressure of 80/50 mmHg, JVD, and muffled heart sounds after blunt chest trauma. What condition do these findings suggest?
Answer: Cardiac tamponade
Beck's triad—hypotension, JVD, and muffled heart sounds—is classic for cardiac tamponade, where pericardial fluid compresses the heart.
During spinal immobilization, a patient with a suspected cervical spine injury becomes combative. What is the priority action?
Answer: Maintain manual in-line stabilization while assessing airway and oxygenation
Manual in-line stabilization must be maintained while simultaneously assessing airway and oxygenation, since hypoxia is a common cause of combativeness.
Which medication is the first-line treatment for a patient in symptomatic bradycardia with a pulse?
Answer: Atropine 0.5 mg IV
Atropine 0.5 mg IV is the first-line drug for symptomatic bradycardia, working by blocking vagal tone to increase heart rate.
You arrive on scene to find a 3-year-old child who is unresponsive and apneic with a strong femoral pulse. What is the most appropriate next action?
Answer: Open the airway and deliver 2 rescue breaths
In a pediatric patient with a pulse but no breathing, rescue breathing is initiated immediately because pediatric arrests are usually respiratory in origin.
