QUESTIONS AND ANSWERS 100%
VERIFIED BY EXPERTS.
1. A 68-year-old male presents with sudden onset of tearing chest pain radiating to the back,
a blood pressure difference of 25 mmHg between arms, and a diminished radial pulse on the
left. Which condition should you most suspect?
A. Myocardial Infarction
B. Pneumothorax
C. Pulmonary Embolism
D. Aortic Dissection
Answer: D
Conceptual Explanation: The classic presentation of tearing pain radiating to the back and
a significant blood pressure differential between extremities is highly suggestive of a
thoracic aortic dissection.
2. When ventilating an apneic patient with a BVM, you notice the chest is not rising
adequately despite a good mask seal. What is the most appropriate next step?
A. Increase the force of ventilations
,B. Perform a head-tilt/chin-lift or jaw-thrust again
C. Switch to a pocket mask
D. Insert a King Airway immediately
Answer: B
Conceptual Explanation: Repositioning the airway is the first step when ventilation is
unsuccessful, as the most common cause of airway obstruction is the tongue.
3. Which of the following is the most definitive sign of a tension pneumothorax in a trauma
patient?
A. JVD and tracheal deviation (late sign)
B. Narrowing pulse pressure
C. Tachycardia
D. Equal breath sounds
Answer: A
Conceptual Explanation: While late, Jugular Venous Distension (JVD) and tracheal
deviation combined with respiratory distress and shock are definitive clinical signs of
tension pneumothorax.
, 4. An 82-year-old female is found confused. Her skin is hot and dry, and her heart rate is 120
bpm. She has been in a house without air conditioning for two days. What is her most likely
condition?
A. Heat Stroke
B. Heat Exhaustion
C. Dehydration
D. Hyperglycemia
Answer: A
Conceptual Explanation: Altered mental status and hot, dry skin (absence of sweating) in
a high-heat environment are hallmark signs of heat stroke, a life-threatening emergency.
5. What is the primary physiological effect of Nitroglycerin when administered to a patient
with chest pain?
A. Increases heart rate to improve perfusion
B. Causes vasoconstriction to increase blood pressure
C. Causes vasodilation and reduces preload
D. Thins the blood to prevent clots
Answer: C
Conceptual Explanation: Nitroglycerin is a vasodilator that reduces the workload of the
heart by decreasing preload and dilating coronary arteries.
