A 55-year-old woman had been receiving long-term treatmentwith phenelzine for her depression. After she consumed Chiantiwine, aged cheddar cheese, processed meats, and dried fruitsone night at a party, the following symptoms developed: a severeheadache, chest pain, rapid heartbeat, enlarged pupils, increasedsensitivity to light, and nausea. What is the most likely cause ofthese symptoms?A. The foods were contaminated with botulinum toxin.B. She had a myocardial infarction.C. She experienced a migraine headache.D. She had an unexpected adverse reaction to the mixture ofalcohol with her antidepressant.E. She had a hypertensive crisis from eating foods high intyramine while taking a monoamine oxidase inhibitor for herdepression

Twenty-five people developed symptoms of nausea, vomiting, and diarrhea three to six hours after attending a church picnic where they ate a ham and green bean casserole with cream sauce. The most likely cause of this case of food intoxication isGroup of answer choicesstaphylococcal enterotoxin.aflatoxin.cholera toxin.erythrogenic toxin.botulinum toxin.

A 47-year-old woman was admitted to the hospital afterexperiencing nausea and vomiting for about 2 days followed bysevere muscle weakness and neurologic symptoms, includingptosis and dysphagia. She indicated she had eaten at a restaurantthe evening before the symptoms began. Laboratory tests werepositive for Clostridium botulinum. The basis for the muscleweakness in this case was most likely because the toxinA. blocked the reuptake of neurotransmitter into presynapticterminals.B. bound irreversibly to the receptor on the postsynapticmembrane at the neuromuscular junction.C. reached the cell body of the motor neuron by diffusion intothe spinal cord.D. exerted its adverse effects by a direct action on the skeletalmuscle.E. prevented the release of acetylcholine from motor neurons.

Phocomelia was a condition caused by consumption of which of these drugs?

A 65-year-old woman comes to the physician’s office with facial pain. The pain is located along her right forehead and began 3 days ago. She describes it as constant, “burning,” and very painful with even light touch. She has never had this kind of pain before. She denies headache, photophobia, changes in vision, eye pain, pain with chewing, fever, or chills. Her past medical history is significant for migraine headaches, but this pain is different from her “typical” headaches. She also has mild hypertension and folate deficiency secondary to inadequate dietary intake. Her temperature is 37.0°C (98.6°F), pulse is 80/min, respirations are 12/min, and blood pressure is 138/90 mm Hg. There are clusters of erythematous papules and vesicles extending from her right frontal prominence down to her nasal bridge. There are small crusted erosions as well. The rash is exquisitely tender to light touch. Which of the following complications is this patient most likely to experience?

Directions: The questions in this section are based on the reasoning in the brief statements or passages. Select the most appropriate among the given answer choices. Select the correct answer Many people report that exposure to certain foods such as cheese, red wine, and chocolate, are associated with the onset of migraine headaches. Other people report that exposure to certain smells (especially strong perfumes) seems to trigger a migraine headache, and some note that exposure to bright and flickering lights can be followed by a migraine. It would seem that a person with a tendency to get migraines should try to find which of these situations is associated with the onset of the headache and then avoid this stimulus. All of the following, if true, would indicate potential problems with the recommendation above except _________________________. radio_button_unchecked the time delay between the trigger and the onset of the headache can make it exceptionally difficult to identify the trigger radio_button_unchecked the presence of a known trigger doesn’t always cause a migraine radio_button_unchecked in many cases an internal hormonal change triggers a migraine radio_button_unchecked in a high proportion of cases the patients report multiple triggers for their headaches radio_button_unchecked most of the known triggers are common and almost unavoidable features of modern life
