Past medical history is significant for hypertension and hyperlipidemia, for which he takes hydrochlorothiazide and atorvastatin. Family history is positive for alcoholic cirrhosis in his father. The patient drinks several beers every night and multiple glasses of wine on the weekends. On physical examination, he appears obese with labored breathing. His heart has a regular rate and rhythm, and his lungs are clear to auscultation bilaterally. Weight loss and abstaining from alcohol are discussed.

In addition, he was admitted to this hospital 1-year ago for a myocardial infarction (MI). The patient reports a 40-pack-year smoking history. However, after his MI, his doctors informed him about how detrimental smoking was to his heart condition. Since then, he has made efforts to cut down and now, for the past seven months, has stopped smoking. He says he used to use smoking as a means of dealing with his work and family stresses.

Q15

A 7-year-old girl presents for a follow-up visit after recent discharge from the hospital. She was admitted about 4 months ago for symptoms of seizures, altered mental status, and fever. She was diagnosed during that admission with herpes encephalitis and recovered well after being treated with acyclovir. However, at this visit, her parents complain of some “strange behaviors” that have developed over the past several weeks. For example, she seems to be snacking uncontrollably and eats significantly more than she did before. Her teacher has also sent home notes stating that she has been chewing on art supplies such as crayons and glue and that she has been sent to the principal twice for rubbing her genitals inappropriately during class. The pediatric neurologist decides to get a follow-up MRI. Which of the following parts of the brain is most likely to have abnormal findings?

Q16

A 3-month-old girl with an immunodeficiency syndrome has been hospitalized for 1 month due to a severe pulmonary infection. Her family came to visit her daily in the beginning of her hospital stay; however, since their car broke down they have been unable to visit for the last 2 weeks. While the infection has now been resolved with proper treatment and supportive care, the girl's nurse is concerned that the patient is becoming increasingly withdrawn. Specifically, the nurse has noticed that since the family has stopped visiting, the girl seems to shy away from contact and sometimes even becomes unresponsive to verbal or visual cues. Which of the following is most likely true about this infant's condition?

Q17

A 3-year-old child is brought to the pediatrician by his mother who states that he has been fussy for the past two days. She says that he has had a runny nose, a cough, a sore throat, and decreased appetite. Vital signs are within normal limits. Physical exam reveals a slightly erythematous oropharynx and clear nasal discharge. The mother states that she is a single mother working at a busy law firm. The mother demands that the child receive antibiotics, as her babysitter refuses to care for the child unless he is treated with antibiotics. You diagnose the child with the common cold and inform the mother that antibiotics are not indicated. She is infuriated and accuses you of refusing to treat her child appropriately. How should you respond?

Q18

A 52-year-old man comes to the physician because of a 3-week history of a cough and hoarseness. He reports that the cough is worse when he lies down after lunch. His temperature is 37.5°C (99.5°F); the remainder of his vital signs are within normal limits. Because the physician has recently been seeing several patients with the common cold, the diagnosis of a viral upper respiratory tract infection readily comes to mind. The physician fails to consider the diagnosis of gastroesophageal reflux disease, which the patient is later found to have. Which of the following most accurately describes the cognitive bias that the physician had?

Q19

An 87-year-old man with glioblastoma multiforme is informed that the size and location of the tumor make operative resection impossible, and he has a prognosis of between 3-6 months. The patient then asks whether it would be possible to get a prescription for lethal medications so that he would be able to end his life if his situation deteriorated further. The physician says that he is unable to prescribe such drugs because assisted suicide is not legal in their state. Refusing to help a patient commit suicide is most consistent with which of the following ethical principles?

Q20

A 38-year-old woman comes to the physician for the first time because of a 2-year history of lower back pain and fatigue. She also says that she occasionally feels out of breath.

Extensive workup including blood and urine tests, abdominal ultrasound, MRI of the back, and cardiac stress testing have shown no abnormalities. The patient asks for a medication to alleviate her symptoms. Which of the following is the most appropriate response by the physician?
