OSCE OSCE Clinical Reasoning and Diagnosis 1 — Questions and Answers
Question 1: A patient presents with sudden onset chest pain radiating to the left arm and diaphoresis. What is the most appropriate immediate clinical action in an OSCE station?
- Obtain a 12-lead ECG and notify the physician immediately (Correct answer)
- Administer oral aspirin without further assessment
- Perform a detailed social history before any intervention
- Schedule an elective stress test
Correct answer: Obtain a 12-lead ECG and notify the physician immediately
Chest pain with radiation and diaphoresis suggests acute MI, requiring immediate ECG and physician notification.
Question 2: During an OSCE, you assess a patient who is confused and has a blood glucose of 45 mg/dL. Which clinical reasoning step should come first?
- Treat the hypoglycemia immediately with oral glucose or IV dextrose (Correct answer)
- Document findings and wait for the attending physician
- Order a full metabolic panel before intervening
- Reassess the patient in 30 minutes
Correct answer: Treat the hypoglycemia immediately with oral glucose or IV dextrose
A blood glucose of 45 mg/dL indicates hypoglycemia, which requires immediate treatment to prevent further neurological compromise.
Question 3: In an OSCE clinical reasoning station, a patient has a positive Murphy's sign. Which condition does this finding most strongly suggest?
- Acute cholecystitis (Correct answer)
- Appendicitis
- Pancreatitis
- Peptic ulcer disease
Correct answer: Acute cholecystitis
Murphy's sign — pain and inspiratory arrest on right upper quadrant palpation — is a classic indicator of acute cholecystitis.
Question 4: A patient presents with fever, stiff neck, and photophobia. Using clinical reasoning in an OSCE, what is the priority diagnosis to rule out?
- Bacterial meningitis (Correct answer)
- Tension headache
- Migraine with aura
- Sinusitis
Correct answer: Bacterial meningitis
The triad of fever, neck stiffness, and photophobia is the classic presentation of bacterial meningitis, a life-threatening emergency.
Question 5: An OSCE candidate is presented with a patient who has unilateral leg swelling, warmth, and tenderness. What is the most appropriate next diagnostic reasoning step?
- Assess for deep vein thrombosis using a clinical prediction tool such as the Wells score (Correct answer)
- Immediately prescribe anticoagulation without further assessment
- Order bilateral knee X-rays
- Recommend elevation and discharge the patient
Correct answer: Assess for deep vein thrombosis using a clinical prediction tool such as the Wells score
The Wells score is a validated clinical prediction tool used to stratify DVT probability before ordering confirmatory imaging.
Question 6: In a clinical reasoning OSCE station, a patient has wheezing, tachypnea, and accessory muscle use. After initiating bronchodilator therapy, what is the most important monitoring parameter?
- Oxygen saturation and respiratory rate (Correct answer)
- Blood pressure only
- Temperature and skin color
- Urine output
Correct answer: Oxygen saturation and respiratory rate
Monitoring oxygen saturation and respiratory rate after bronchodilator therapy directly measures the response to treatment in acute respiratory distress.
