Question 1:
A 45-year-old female presents to the emergency department with acute abdominal pain and
vomiting. She has a history of gallstones. What is the most appropriate initial imaging study?
Answer:
Ultrasound of the abdomen.
Rationale:
Ultrasound is the preferred initial imaging modality for suspected gallbladder pathology (like
acute cholecystitis) because it is non-invasive and can identify gallstones, thickened
gallbladder walls, and fluid around the gallbladder.
Question 2:
A 60-year-old male with a history of hypertension presents with sudden onset severe
headache and photophobia. What is the most concerning diagnosis to rule out?
Answer:
Subarachnoid hemorrhage.
Rationale:
The sudden onset of a severe headache (often described as a "thunderclap headache") in a
patient with risk factors for vascular disease raises concern for subarachnoid hemorrhage,
necessitating immediate CT imaging.
Question 3:
Which of the following is a common side effect of beta-blocker therapy?
A) Hypertension
B) Bradycardia
C) Hyperglycemia
D) Tachycardia
Answer:
B) Bradycardia.
Rationale:
Beta-blockers can decrease heart rate, leading to bradycardia as a common side effect,
especially in patients who are already on other medications affecting heart rate or in those
with preexisting conduction abnormalities.
,Question 4:
A 30-year-old female presents with fever, cough, and pleuritic chest pain. A chest x-ray
shows a pleural effusion. What is the next best step in management?
Answer:
Thoracentesis.
Rationale:
Thoracentesis is indicated to both relieve symptoms from the pleural effusion and to analyze
the fluid for diagnostic purposes (e.g., infection, malignancy, or other causes of effusion).
Question 5:
In a patient presenting with severe allergic reaction, which of the following is a critical first-
line intervention?
A) Oral antihistamines
B) Epinephrine
C) Corticosteroids
D) Intravenous fluids
Answer:
B) Epinephrine.
Rationale:
Epinephrine is the first-line treatment for anaphylaxis, as it rapidly alleviates airway swelling,
bronchospasm, and cardiovascular symptoms. Other treatments like antihistamines and
corticosteroids are secondary.
Question 6:
A 50-year-old male presents with a sudden onset of unilateral facial droop and inability to
raise his left eyebrow. What is the most likely diagnosis?
Answer:
Bell's palsy.
Rationale:
Unilateral facial weakness, particularly in the context of acute onset without other
neurological deficits, suggests Bell's palsy, which involves inflammation of the facial nerve.
Question 7:
Which laboratory finding is most indicative of acute kidney injury due to prerenal causes?
,A) Urine sodium <20 mEq/L
B) Urine osmolality <300 mOsm/kg
C) Urine specific gravity <1.010
D) Urine creatinine clearance >90 mL/min
Answer:
A) Urine sodium <20 mEq/L.
Rationale:
In prerenal acute kidney injury, the kidneys conserve sodium to maintain blood volume,
leading to a urine sodium concentration of less than 20 mEq/L.
Question 8:
What is the most common cause of community-acquired pneumonia in adults?
Answer:
Streptococcus pneumoniae.
Rationale:
Streptococcus pneumoniae is the most common pathogen responsible for community-
acquired pneumonia in adults, often presenting with fever, cough, and pleuritic chest pain.
Question 9:
A patient presents with a laceration on his forearm. You suspect he needs a tetanus booster.
When should a tetanus booster be administered?
Answer:
If the last booster was more than 10 years ago (or 5 years for dirty wounds).
Rationale:
A tetanus booster is recommended every 10 years for routine vaccinations. For dirty or
contaminated wounds, a booster is given if it has been more than 5 years since the last shot.
Question 10:
A 65-year-old female presents with chest pain, dyspnea, and a history of smoking. Which
diagnostic test is most appropriate to evaluate for a pulmonary embolism?
Answer:
CT pulmonary angiography.
Rationale:
CT pulmonary angiography is the gold standard for diagnosing pulmonary embolism,
providing quick and accurate visualization of the pulmonary arteries.
, Question 11:
A 50-year-old male presents with acute onset of severe chest pain radiating to his back. He
has a history of hypertension. What is the most likely diagnosis?
Answer:
Aortic dissection.
Rationale:
Acute, severe chest pain that radiates to the back, especially in a patient with hypertension, is
highly suggestive of aortic dissection, a life-threatening condition requiring immediate
imaging and intervention.
Question 12:
In a patient with suspected opioid overdose, what is the most appropriate initial management
step?
Answer:
Administer naloxone (Narcan).
Rationale:
Naloxone is an opioid antagonist used as an antidote for opioid overdose, reversing
respiratory depression and sedation effectively.
Question 13:
A 28-year-old female presents with fever, dysuria, and flank pain. What is the most
appropriate initial imaging study to evaluate her condition?
Answer:
Ultrasound of the kidneys.
Rationale:
An ultrasound is the initial imaging choice to evaluate for urinary tract obstruction or
pyelonephritis, especially in pregnant women, as it avoids radiation exposure.
Question 14:
Which of the following is a classic finding in a patient with hyperthyroidism?
A) Weight gain
B) Bradycardia
C) Heat intolerance
D) Cold intolerance
Answer:
C) Heat intolerance.
