Autonomic/CV Drugs — MCQs

A 58-year-old male presents to his primary care physician for a check-up. He reports that he visited an urgent care clinic last week for seasonal allergies; he was instructed at that encounter to follow-up with his primary care doctor because his blood pressure measured at that time was 162/88. He denies any bothersome symptoms and reports that he feels well overall. The patient denies any past history of medical problems other than cholecystitis that was surgically treated over 30 years ago. On further probing through review of symptoms, the patient reports that he often feels 'shaky' when performing tasks; he reports that his hands shake whenever he attempts to eat or drink something and also when he writes. Vital signs obtained at the visit are as follows: T 37.2 C, HR 88, BP 154/96, RR 20, SpO2 98%. A second blood pressure reading 10 minutes after the first set of vitals shows a blood pressure of 150/94. Physical examination is overall unremarkable and does not reveal a resting tremor in either hand; however, when the patient is asked to pick up a pen to fill out insurance paperwork, you note a fine shaking in his right hand. Which of the following is the next best step in the management of this patient?

A primary care physician who focuses on treating elderly patients is researching recommendations for secondary prevention. She is particularly interested in recommendations regarding aspirin, as she has several patients who ask her if they should take it. Of the following, which patient should be started on lifelong aspirin as monotherapy for secondary prevention of atherosclerotic cardiovascular disease?

A 34-year-old man comes to the physician because of palpitations, shortness of breath, diarrhea, and abdominal cramps for 2 months. Physical examination shows cutaneous flushing of the face. Auscultation of the chest shows bilateral wheezing. A 24-hour urine collection shows increased 5-hydroxyindoleacetic acid (5-HIAA) concentration. A contrast-enhanced CT scan of the abdomen shows an intestinal tumor with extensive metastasis to the liver. A diagnosis of an inoperable disease is made and the patient is started on treatment with octreotide. Six weeks later, the patient's symptoms have improved except for his abdominal pain and frequent loose stools. The physician suggests enrolling the patient in a trial to test additional treatment with a new drug that has been shown to improve symptoms in other patients with the same condition. The expected beneficial effect of this new drug is most likely caused by inhibition of which of the following?

A 22-year-old woman is brought to the emergency department after being struck by a car while crossing the street. She has major depressive disorder with psychosis. Current medications include sertraline and haloperidol. Vital signs are within normal limits. X-ray of the lower extremity shows a mid-shaft femur fracture. The patient is taken to the operating room for surgical repair of the fracture. As the surgeon begins the internal fixation, the patient shows muscle rigidity and profuse diaphoresis. Her temperature is 39°C (102.2°F), pulse is 130/min, respirations are 24/min, and blood pressure is 146/70 mm Hg. The pupils are equal and reactive to light. The end tidal CO2 is 85 mm Hg. Which of the following is the most appropriate treatment for this patient's condition?

A 58-year-old man presents with an occasional tremor in his left hand. While the tremor disappears when he moves his hand, he finds it increasingly difficult to type and feels his handwriting has gotten much smaller. He finds the tremor is more pronounced when he is stressed out at work. He also complains of a decrease in his sense of smell, mild constipation, difficulty sleeping, and increased urinary frequency – all of which he feels is him ‘just getting older’. No significant past medical history and no current medications. Vital signs are a pulse of 74/min, a respiratory rate of 14/min, a blood pressure of 130/70 mm Hg, and a temperature of 36.7°C (98.0°F). On physical examination, a resting tremor in the left hand is noted with mild rigidity in the upper limbs and mask-like faces. While performing finger-to-nose and rapid alternating movements, he has some difficulty. All his movements are slow. The sensation is intact. Gait is normal except for a decreased arm swing. Which of the following drugs acts directly on the receptors responsible for this patient’s condition?
