COMSAE 107 EXAM MASTERY COMPLETE BLUEPRINT QUESTIONS REVIEW WITH CLINICAL VIGNETTES, OMM INTEGRATION & STEP-BY-STEP RATIONALES AND VERIFIED ANSWERS 1. A 45-year-old male with a history of alcohol abuse presents with severe epigastric pain radiating to the back, nausea, and vomiting. Serum amylase and lipase are markedly elevated. Which spinal level is most likely to exhibit a corresponding viscerosomatic reflex? A) T1-T4 B) T5-T9 C) T10-T11 D) L1-L2 Correct Answer: B The pancreas receives its sympathetic innervation from T5-T9, and acute pancreatitis would elicit a viscerosomatic reflex at this level. 2. A 68-year-old female complains of progressive hearing loss, tinnitus, and a sensation of fullness in her left ear. An MRI reveals a mass at the cerebellopontine angle. Which cranial nerve is most directly at risk of being compressed by this tumor? A) Cranial Nerve V B) Cranial Nerve VII C) Cranial Nerve VIII D) Cranial Nerve IX Correct Answer: C The tumor described is an acoustic neuroma (vestibular schwannoma), which arises from the vestibulocochlear nerve (CN VIII). 3. A 55-year-old male with a history of hypertension and type 2 diabetes presents with a painful, erythematous, swollen right great toe. Joint aspiration reveals negatively birefringent, needle-shaped crystals. What is the first-line pharmaceutical agent for the acute management of this condition? A) Allopurinol B) Colchicine C) Febuxostat D) Probenecid Correct Answer: B This is acute gout. Colchicine, NSAIDs, or corticosteroids are first-line for acute flares. Allopurinol and febuxostat are used for chronic management. 4. A 72-year-old male presents with a several-month history of progressive, symmetric rigidity, bradykinesia, and a resting tremor in his right hand. His gait is shuffling. Administration of which of the following pharmaceutical agents is most likely to improve his symptoms? A) Haloperidol B) Levodopa C) Donepezil D) Rivastigmine Correct Answer: B This patient has Parkinson's disease, which is caused by a loss of dopaminergic neurons in the substantia nigra. Levodopa is a precursor to dopamine and is the most effective symptomatic treatment. 5. A 32-year-old female presents with acute-onset right lower quadrant pain, nausea, and fever. On physical exam, she has rebound tenderness at McBurney's point. During an OPP evaluation, you would expect to find a tissue texture change at which spinal level? A) T10 B) T11 C) T12 D) L1 Correct Answer: A The appendix is an embryologic midgut structure and receives its sympathetic innervation from T10. Appendicitis would cause a viscerosomatic reflex at T10. 6. A 60-year-old male with a history of COPD presents with worsening dyspnea and a chronic cough. An arterial blood gas reveals a pH of 7.32, PaCO2 of 58 mmHg, and HCO3- of 28 mEq/L. What is the most likely underlying acid-base disturbance? A) Acute respiratory acidosis B) Chronic respiratory acidosis with compensation C) Metabolic alkalosis D) Mixed respiratory and metabolic acidosis Correct Answer: B The elevated PaCO2 indicates respiratory acidosis. The HCO3- is elevated as a compensatory response by the kidneys (metabolic compensation), which takes a few days, suggesting this is a chronic condition. 7. A 25-year-old male is brought to the emergency department after a motor vehicle accident. He has a palpable fracture of his mid-shaft femur. He becomes acutely short of breath and hypoxic. A CT angiography reveals filling defects in the pulmonary arteries. What is the most likely underlying source of these emboli? A) Amniotic fluid B) Air bubble C) Bone marrow fat D) Atherosclerotic plaque Correct Answer: C A long bone fracture can release fat globules from the bone marrow into the venous system, leading to a fat embolism syndrome. 8. A 48-year-old female presents with fatigue, weight gain, cold intolerance, and constipation. Her skin is dry, and her deep tendon reflexes are delayed. A TSH level is markedly elevated. The underlying pathogenesis of her primary condition most likely involves: A) Autoimmune destruction of the thyroid gland B) A pituitary adenoma secreting TSH C) A defect in thyroid hormone conversion in peripheral tissues D) Iodine deficiency Correct Answer: A This is primary hypothyroidism. The most common cause in the US is Hashimoto's thyroiditis, an autoimmune disease. 9. A 70-year-old male with a history of diabetes presents with a painful, non-healing ulcer on the plantar surface of his right foot. The ulcer is deep and probes to bone. An X-ray shows osteomyelitis. The most common causative organism for this infection is: A) Escherichia coli B) Pseudomonas aeruginosa
