MCATS Questions Focused on Pathophysiology & Symptomatology
1. Guillain-Barre syndrome is an autoimmune disease which attack gangliosides, which are molecules found on the outside of a cell. Patients with this disease have a nerve conduction block which is often caused by a slowed conduction potential and can lead to paralysis. Which type of cell is attacked?Correct: Schwann Cells
Incorrect: Astrocytes; Oligodendrocytes; Neurons
2. An increased number of microglia would indicate which of the following?Correct: Bacterial meningitis
Incorrect: Multiple sclerosis; Subdural hematoma; Peripheral nerve damage
3. Steatorrhea is the presence of increased fat in feces. Which organ is least likely to be the cause of a patient’s steatorrhea?Correct: Stomach
Incorrect: Pancreas; Small intestine; Liver
4. Which of the following would most likely be found in the esophagus of a patient suffering from gastroesophageal reflux disease?Correct: Pepsin
Incorrect: Trypsin; Chymotrypsin; Carboxypeptidase
5. Curare is a naturally-occurring compound that competitively binds to nicotinic acetylcholine receptors on muscle cells. Which of the following symptoms might be seen in a patient who has been exposed to curare?Correct: Diaphragmatic paralysis Incorrect: Excessive salivation; Muscle spasticity; Cardiac arrest
