Question 1
A 45-year-old male patient presents with complaints of fatigue, weight loss, and
increased thirst. His blood pressure is 150/90 mmHg, and his fasting blood glucose
level is 180 mg/dL. Which of the following is the most likely diagnosis?
A. Type 2 Diabetes Mellitus
B. Hyperthyroidism
C. Hypertension
D. Acute Myocardial Infarction
Answer: A
Rationale: The patient's symptoms of fatigue, weight loss, and increased thirst,
along with elevated fasting blood glucose levels (180 mg/dL), are classic signs of
Type 2 Diabetes Mellitus. Hypertension and hyperthyroidism could also be
present, but they don't fully account for the patient's symptoms.
Question 2
Which of the following findings would most likely indicate acute pericarditis?
A. Pleural friction rub
B. Decreased heart sounds
C. Sudden sharp chest pain that worsens with inspiration
D. Jugular venous distention
Answer: C
Rationale: Acute pericarditis is typically characterized by sharp, pleuritic chest
pain that worsens with inspiration or coughing. The pain may improve when the
patient sits up and leans forward. A pleural friction rub is often heard on
auscultation, but the pain pattern is key.
Question 3
A 32-year-old female presents with a 3-day history of a red, swollen, and painful
pg. 1
,right lower leg. The patient also reports feeling feverish. Upon examination, the
skin is warm to the touch, and there is localized erythema. What is the most likely
diagnosis?
A. Deep Vein Thrombosis (DVT)
B. Cellulitis
C. Sprain
D. Gout
Answer: B
Rationale: Cellulitis is a bacterial skin infection often caused by Streptococcus or
Staphylococcus species, resulting in red, swollen, and painful skin, sometimes
accompanied by fever. DVT could present with swelling and pain but is usually
not associated with fever or erythema.
Question 4
A patient has a history of asthma and presents to the clinic with increased shortness
of breath, wheezing, and a decreased peak flow rate. The patient's pulse oximetry
reading is 92%. Which of the following is the most appropriate next step in
management?
A. Administer oxygen and monitor the patient
B. Administer a short-acting beta-agonist (SABA) inhaler
C. Begin IV corticosteroids
D. Initiate mechanical ventilation
Answer: B
Rationale: In patients with asthma exacerbations, the first-line treatment is a short-
acting beta-agonist (e.g., albuterol) to relieve bronchoconstriction. Administering
oxygen or corticosteroids may be appropriate later, but the immediate treatment is
aimed at improving airflow.
Question 5
A 60-year-old male with a history of chronic alcohol use presents with confusion,
ataxia, and a wide-based gait. He is found to have a deficiency in thiamine. What is
the most likely diagnosis?
A. Wernicke-Korsakoff syndrome
B. Multiple sclerosis
C. Parkinson's disease
pg. 2
,D. Alzheimer's disease
Answer: A
Rationale: Wernicke-Korsakoff syndrome is a neurologic disorder caused by
thiamine deficiency, often seen in chronic alcohol users. It presents with confusion,
ataxia, and ophthalmoplegia, progressing to Korsakoff's psychosis with memory
deficits.
Question 6
A 25-year-old female presents with a butterfly-shaped rash across her cheeks and
nose, along with photosensitivity and joint pain. The most likely diagnosis is:
A. Systemic Lupus Erythematosus (SLE)
B. Rheumatoid Arthritis
C. Psoriasis
D. Rosacea
Answer: A
Rationale: The butterfly-shaped rash across the cheeks and nose, along with joint
pain and photosensitivity, is characteristic of Systemic Lupus Erythematosus
(SLE), an autoimmune disorder that can affect multiple organ systems.
Question 7
A 45-year-old female presents with chest pain and shortness of breath. An ECG
reveals ST-segment elevation in leads II, III, and aVF. Which of the following is
the most appropriate treatment?
A. Nitroglycerin and aspirin
B. Administer thrombolytics or prepare for percutaneous coronary intervention
(PCI)
C. Beta-blockers and ACE inhibitors
D. Oxygen therapy only
Answer: B
Rationale: ST-segment elevation in leads II, III, and aVF suggests an acute
inferior wall myocardial infarction. Immediate treatment includes thrombolytics or
PCI to restore coronary blood flow.
Question 8
A 72-year-old male presents with new-onset confusion, tremors, and bradykinesia.
pg. 3
, His history is significant for depression, for which he has been taking an
antidepressant for several years. What is the most likely diagnosis?
A. Parkinson's disease
B. Alzheimer's disease
C. Delirium
D. Serotonin syndrome
Answer: A
Rationale: The combination of new-onset confusion, tremors, and bradykinesia in
an elderly patient with a history of depression may suggest Parkinson's disease, a
neurodegenerative disorder. Although serotonin syndrome can present with similar
symptoms, Parkinson's is more likely in this case.
Question 9
A 40-year-old male presents with severe headache, photophobia, and a stiff neck.
Which of the following tests is most likely to confirm the diagnosis of meningitis?
A. MRI of the brain
B. CT scan of the brain
C. Lumbar puncture
D. Blood cultures
Answer: C
Rationale: A lumbar puncture is the definitive diagnostic test for meningitis,
allowing for analysis of cerebrospinal fluid (CSF) to identify the causative
organism and assess for signs of inflammation.
Question 10
A 65-year-old female with a history of hypertension and diabetes mellitus presents
with a sudden onset of severe headache, nausea, and vomiting. She is found to
have a blood pressure of 220/120 mmHg and papilledema on funduscopic
examination. The most likely diagnosis is:
A. Hypertensive emergency
B. Subarachnoid hemorrhage
C. Acute glaucoma
D. Migraine headache
Answer: A
Rationale: A hypertensive emergency is characterized by severely elevated blood
