141) After an uncomplicated pregnancy and cesarean section for breech presentation, twins are born at 32 weeks’ gestation to a 24-year-old primigravida mother. Twin A weighs 1610 g (3.5 lb) and has Apgar scores of 8 and 9 at 1 and 5 minutes, respectively. Twin B weighs 1600 g (3.5 lb) and has Apgar scores of 7 and 8 at 1 and 5 minutes, respectively. Within minutes of birth, twin B becomes mildly cyanotic and tachypneic with subcostal retractions, expiratory grunting, and nasal flaring. Twin B’s blood pressure is 58/39 mm Hg, heart rate is 130/min, respiratory rate is 100/min, and temperature is 37.0°C (98.6°F). Twin B is intubated and given 70% fraction of inspired oxygen. Compared to twin A, what is twin B at greater risk of developing?

142) A 32-year-old white man with HIV and a re- cent CD4+ cell count of 400/mm³ presents to the emergency department with a 3-day history of fever, anorexia, cough, and night sweats. He recently returned from a camping vacation in Arizona, approximately 1 month prior to presentation. He also describes diffuse joint pains. His temperature is 38.9°C (102°F), oxygen saturation is 99% on room air, and there is a rash on his arms and hands. There is dullness to percussion at the right lung base. X-ray of the chest reveals a small right-sided infiltrate and hilar lymphadenopathy. Sputum analysis does not reveal any organisms. He reportedly had a negative purified protein derivative test 2 months ago. Which of the following is the most likely diagnosis?

143) A 55-year-old man was admitted to the hospital 2 weeks ago for rapid onset of cough, fatigue, and pleuritic chest pain. He has worked as a sandblaster for the past year. When first seen in the hospital, he denied hemoptysis and smoking. Currently, the patient is intubated and on assist-control ventilation. His temperature is 36.7°C (98°F), pulse is 96/min, blood pressure is 138/85 mm Hg, and respiratory rate is 18/ min. A recent arterial blood gas study showed a pH 7.42, arterial carbon dioxide pressure of 36 mm Hg, and arterial oxygen pressure of 110 mm Hg while on 100% oxygen. Physical examination is significant for diffuse crackles throughout both lung fields, a loud pulmonic component of the second heart sound, and jugular venous distention of 9 cm with a prominent A wave, a left parasternal heave, and symmetric 3+ lower extremity pitting edema. Which of the following is the most likely diagnosis?

144) A 30-year-old woman presents to her physician’s office because of 3 months of nonproductive cough, exertional dyspnea, fatigue, malaise, and blurred vision. She denies weight loss, fever, chills, sweats, recent travel, or sick contacts. She works on the assembly line of an electronics plant. Vital signs are unremarkable. Physical examination reveals she has tender red papules over her shins. The patient said she first noticed the bumps when she changed oral contraceptive pills (her only medication), but assumed they would disappear. X-ray of the chest shows bilateral hilar lymphadenopathy with pulmonary infiltrates. Laboratory findings are: WBC count: 5600/mm3, Hemoglobin: 14.3 g/dL, Platelet count: 300,000/mm3, Na+: 140 mEq/L, K+: 4.2 mEq/L, Cl−: 108 mEq/L, Ca2+: 16 mg/dL, CO2: 24 mmol/L, Blood urea nitrogen: 10 mg/dL, Creatinine: 1.0 mg/dL. Culture of bronchoalveolar lavage fluid is neg- ative. Which of the following is the most likely diagnosis?
Berylliosis
Fungal infection
Lymphoma
Sarcoidosis
Tuberculosis
145) A 58-year-old man presents to the emergency department complaining of fever and chills. The fever started last night and has not subsided, even though he took acetaminophen. He had a successful appendectomy 3 days ago and was discharged from the hospital 2 days ago. His only medication is ibuprofen, which is adequately controlling his pain. He is a 30-pack-year smoker with a chronic cough productive of white sputum. He has noticed increased sputum production, which has become yellowish-green. He denies dysuria, urgency, or frequency. His temperature is 38.4°C (101.1°F), heart rate is 88/min, respiratory rate is 16/min, and blood pressure is 126/74 mm Hg. On examination he appears to be tired but not in acute distress. Pulmonary examination is limited because deep inhalation causes coughing and slight abdominal pain. There is no tactile fremitus or dullness to percussion. He has a slightly erythematous, appropriately tender healing incision in the right lower quadrant without exudates and normal active bowel sounds. Extremities are warm and well perfused without erythema or edema. Pulses are intact. Which of the following most likely could have prevented this condition?

Early removal of the Foley catheter
Early removal of the intravenous catheter
Pre- and postoperative antibiotic prophylaxis
