PERFECT SCORE A+
◉ What is the highest priority diagnostic test for suspected acute
coronary syndrome (ACS)? Answer: A 12-lead ECG, to be performed
and interpreted within 10 minutes.
◉ Which cardiac biomarkers are most sensitive for identifying
myocardial injury? Answer: Troponins.
◉ What is the definitive bedside test for cardiac tamponade? Answer:
Echocardiogram.
◉ What is the recommended immediate pharmacological treatment for
ACS? Answer: Aspirin (160-325 mg chewed).
◉ What is the first-line medication for cardiac arrest? Answer:
Epinephrine.
◉ What medication is used for refractory ventricular fibrillation?
Answer: Amiodarone.
◉ What is the primary treatment for symptomatic bradycardia? Answer:
Atropine.
,◉ Why are direct vasodilators contraindicated in aortic dissections?
Answer: They can increase the risk of dissection propagation.
◉ What is reflex tachycardia? Answer: An increased heart rate triggered
by a rapid drop in blood pressure due to vasodilators.
◉ What is the proper management sequence for a hypertensive
emergency involving an aortic dissection? Answer: -blockers first,
followed by vasodilators.

respiratory failure? Answer: Arterial Blood Gas (ABG) analysis.

Answer: CT Angiography.
◉ What is the first-line treatment for acute asthma and COPD
bronchospasms? Answer: Short-acting beta-agonists
(Albuterol/Salbutamol).
◉ What is the gold standard diagnostic test for differentiating stroke
types? Answer: An emergent non-contrast CT head.

within specific time windows? Answer: rtPA (Fibrinolytics).
, ◉ What is mandatory for all females of childbearing age presenting with
abdominal pain? Answer: A pregnancy test to rule out ectopic pregnancy.
◉ What is the primary treatment for seizures associated with eclampsia?
Answer: Magnesium Sulfate.
◉ What is used to diagnose carbon monoxide poisoning? Answer:
Carboxyhemoglobin levels.
◉ What is the first-line treatment for anaphylaxis? Answer: Epinephrine
(IM/IV).
◉ What are bronchopulmonary segments? Answer: Functional,
anatomic, and surgical subunits of the lung, each supplied by a specific
tertiary bronchus.
◉ How many segments does the right lung have? Answer: 10 segments.
◉ What is the clinical significance of bronchopulmonary segments?
Answer: They allow for targeted surgical removal of diseased segments
and localization of diseases.
