Introduction
This comprehensive examination is designed to assess the foundational knowledge
and clinical reasoning skills expected of a first-year Emergency Medicine resident
preparing for the ALIEM In-Training Examination. The questions span core domains
of emergency medicine practice, emphasizing the integration of basic science
principles with clinical application in high-acuity settings. Each scenario-based
question is crafted to mirror real-world patient presentations, challenging the
examinee to prioritize differential diagnoses, select appropriate diagnostic studies,
and implement evidence-based management strategies. The inclusion of regulatory,
ethical, and professional standards ensures a holistic evaluation of the resident's
readiness for independent practice. A balanced distribution of question difficulty is
provided to thoroughly gauge proficiency across all competency levels.
,Section One: Questions 1-50
1. A 68-year-old male with a history of COPD presents with acute onset of
severe dyspnea. He is unable to speak in full sentences, has a respiratory rate of
32/min, and uses accessory muscles. On auscultation, breath sounds are faint
with diffuse expiratory wheezes. His SpO2 is 86% on room air. What is the most
appropriate initial intervention?
A. Administer albuterol nebulizer
B. Obtain a STAT chest X-ray
C. Administer non-invasive positive pressure ventilation (NIPPV)
D. Perform a needle decompression
🟢 Correct Answer: C. Administer non-invasive positive pressure ventilation
(NIPPV)
🔴 Explanation: This patient presents with a severe COPD exacerbation and
respiratory failure (SpO2 < 90%, accessory muscle use). Non-invasive positive
pressure ventilation (NIPPV) is the first-line intervention for acute hypercapnic
respiratory failure in COPD patients, as it reduces the work of breathing, improves
gas exchange, and decreases the need for intubation.
2. A 45-year-old woman presents with sudden-onset, severe headache
described as "the worst of my life." Her blood pressure is 210/120 mmHg and
heart rate is 110 bpm. She is alert but nauseated. Which diagnostic test is most
critical to perform emergently?
A. Lumbar puncture
B. CT angiography of the head
C. Non-contrast CT of the head
D. Serum electrolyte panel
,🟢 Correct Answer: C. Non-contrast CT of the head
🔴 Explanation: The classic presentation of a sudden, severe "thunderclap"
headache with hypertension is highly concerning for subarachnoid hemorrhage
(SAH). A non-contrast CT of the head is the most critical initial diagnostic test, as
it has high sensitivity for detecting acute SAH within the first 6 hours.
3. A 32-year-old male is brought in by ambulance following a high-speed
motor vehicle collision. He is conscious but hypotensive. Focused Assessment
with Sonography in Trauma (FAST) exam reveals free fluid in the hepatorenal
space. What is the next best step in management?
A. Immediate CT scan of the abdomen and pelvis
B. Transfer to the operating room for exploratory laparotomy
C. Administration of 2 units of packed red blood cells
D. Placement of a diagnostic peritoneal lavage (DPL)
🟢 Correct Answer: B. Transfer to the operating room for exploratory laparotomy
🔴 Explanation: A positive FAST exam indicating free fluid (hemorrhage) in the
abdomen of a hypotensive trauma patient signifies hemodynamic instability from
intra-abdominal bleeding. The patient requires immediate surgical intervention;
thus, transfer to the operating room for an exploratory laparotomy is the next
best step, bypassing further diagnostic imaging.
4. Which of the following is the most common cause of cardiac arrest in infants
and children?
A. Ventricular fibrillation
B. Supraventricular tachycardia
, C. Asphyxia
D. Congenital heart disease
🟢 Correct Answer: C. Asphyxia
🔴 Explanation: Unlike adults, where ventricular fibrillation is the most common
initial rhythm, cardiac arrest in infants and children is typically the result of
progressive respiratory failure or shock leading to asphyxia. Effective ventilation
and oxygenation are paramount in pediatric resuscitation.
5. A 28-year-old female presents with palpitations. Her ECG shows a narrow-
complex tachycardia at a rate of 180 bpm with no visible P waves. She is
hemodynamically stable. Which of the following maneuvers is most
appropriate to attempt first?
A. Administer amiodarone 150 mg IV
B. Perform synchronized cardioversion
C. Perform carotid sinus massage
D. Administer adenosine 6 mg IV rapid push
🟢 Correct Answer: D. Administer adenosine 6 mg IV rapid push
🔴 Explanation: This ECG is consistent with supraventricular tachycardia (SVT). In
a hemodynamically stable patient, vagal maneuvers are attempted first, but
among the given options, adenosine (6 mg IV rapid push) is the appropriate first-
line pharmacologic intervention. Vagal maneuvers are preferred before
adenosine, but were not an option.
6. A 55-year-old male with a history of hypertension presents with acute
substernal chest pain radiating to his left arm. His initial ECG shows ST-segment
