OSCE Emergency Assessment 4

Question 1

A patient presents with ST-elevation in leads II, III, and aVF. Which coronary artery is most likely occluded?

Accepted Answer

Right coronary artery

Answer

ST elevation in the inferior leads (II, III, aVF) indicates an inferior STEMI, most commonly caused by right coronary artery occlusion.

Question 2

During a secondary survey, a patient reports flank pain, gross hematuria, and you note a seatbelt sign across the abdomen. Which organ injury is MOST suspected?

Accepted Answer

Renal injury

Answer

Flank pain combined with hematuria strongly suggests renal injury, which is common with deceleration trauma and lateral compression.

Question 3

Which rhythm requires immediate unsynchronized defibrillation?

Accepted Answer

Ventricular fibrillation

Answer

Ventricular fibrillation is a pulseless, chaotic rhythm with no organized activity, requiring immediate unsynchronized defibrillation.

Question 4

In a pediatric patient, which formula is used to estimate the correct endotracheal tube size (uncuffed)?

Accepted Answer

(Age/4) + 4

Answer

The formula (Age/4) + 4 estimates uncuffed ETT size in mm for pediatric patients, a standard PALS teaching point.

Question 5

A patient presents with hypotension, distended neck veins, and muffled heart sounds after a stab wound to the chest. This is MOST consistent with:

Accepted Answer

Cardiac tamponade

Answer

Beck's triad — hypotension, JVD, and muffled heart sounds — is classic for cardiac tamponade caused by blood accumulating in the pericardial sac.
