AEMCA MCQ 2

Question 1

A patient presents with a tension pneumothorax. Which clinical finding is most specific to this condition?

Accepted Answer

Tracheal deviation away from the affected side

Answer

Tracheal deviation away from the affected side is a classic late sign of tension pneumothorax caused by mediastinal shift from accumulating pressure.

Question 2

When using a bag-valve-mask device on an adult patient, what tidal volume should you target to avoid gastric insufflation?

Accepted Answer

500–600 mL delivered over 1 second

Answer

A tidal volume of 500–600 mL over about 1 second is sufficient for oxygenation and minimizes the risk of gastric insufflation and aspiration.

Question 3

Which of the following is the correct initial dose of epinephrine for anaphylaxis in an adult?

Accepted Answer

0.3–0.5 mg IM (1:1,000) into the anterolateral thigh

Answer

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.

Question 4

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?

Accepted Answer

Cardiac tamponade

Answer

Beck's triad—hypotension, JVD, and muffled heart sounds—is classic for cardiac tamponade, where pericardial fluid compresses the heart.

Question 5

During spinal immobilization, a patient with a suspected cervical spine injury becomes combative. What is the priority action?

Accepted Answer

Maintain manual in-line stabilization while assessing airway and oxygenation

Answer

Manual in-line stabilization must be maintained while simultaneously assessing airway and oxygenation, since hypoxia is a common cause of combativeness.
