A trauma patient has a systolic BP of 70 mmHg, heart rate of 130, and is unresponsive. Which fluid resuscitation strategy is preferred in penetrating torso trauma?
Answer: Permissive hypotension targeting SBP 80-90 mmHg
Permissive hypotension (targeting SBP 80-90 mmHg) is preferred in penetrating torso trauma to avoid diluting clotting factors while maintaining perfusion.
Which finding on a 12-lead ECG is MOST indicative of an ST-elevation myocardial infarction (STEMI) requiring immediate cath lab activation?
Answer: ST elevation ≥1 mm in two or more contiguous leads
ST elevation ≥1 mm in two or more contiguous leads is the hallmark ECG criterion for STEMI requiring emergent reperfusion therapy.
During a high-priority trauma transport, a patient's SpO2 drops from 98% to 82% with diminished breath sounds on the right. What is the MOST likely diagnosis?
Answer: Right-sided tension pneumothorax
Unilateral diminished breath sounds with acute SpO2 decline in a trauma patient is tension pneumothorax until proven otherwise.
What is the correct dose of epinephrine administered during adult cardiac arrest per current AHA ACLS protocol?
Answer: 1 mg IV every 3-5 minutes
Epinephrine 1 mg IV is given every 3-5 minutes during adult cardiac arrest as the primary vasopressor per AHA ACLS guidelines.
A 6-year-old child (22 kg) requires IV fluid resuscitation for dehydration. What is the correct initial bolus volume?
Answer: 220 mL normal saline
The standard pediatric fluid bolus is 20 mL/kg, so a 22 kg child receives 440 mL — but the initial safe bolus is commonly administered as 10-20 mL/kg; 20 mL/kg = 440 mL.
Which of the following is the MOST reliable field indicator of successful endotracheal intubation?
Answer: Continuous waveform capnography
Continuous waveform capnography (ETCO2) is the gold standard for confirming and continuously monitoring correct endotracheal tube placement.
In the management of a patient with severe anaphylaxis, epinephrine should be administered via which route FIRST?
Answer: Intramuscular injection in the anterolateral thigh
Intramuscular epinephrine in the anterolateral thigh achieves faster and more reliable absorption than subcutaneous injection in anaphylaxis.
