An 18-year-old, 55-kg (121-lb) woman has just been intubated for an acute
asthma attack. She has been sedated and paralyzed in order to facilitate
ventilation. Arterial blood gas analysis immediately before intubation revealed:
pH 7.08, PCO2 75 mm Hg, and PO2 63 mm Hg on FIO2 0.4. On bagging, diffuse
high-pitched wheezes are heard. Which of the following is the most appropriate
initial ventilator mode for this patient?
A. Continuous positive airway pressure
B. Pressure support ventilation
C. Assist control volume ventilation
D. Assist control pressure ventilation - CORRECT ANSWER ✔✔ - C
A 56-year-old man presents to the emergency department with a three-day
history of fever, shaking chills, cough, and sputum production. He was previously
in good health and takes only amlodipine for a history of hypertension. In the
emergency department, his heart rate is 130 beats/min, respiratory rate
32breaths/min, blood pressure 80/40 mm Hg, temperature 38.8°C (102°F), and
oxygen saturation 92% on 6 liters of oxygen by nasal cannula. Pulmonary
examination demonstrates crackles and bronchial breath sounds in both lower
lobes. A chest radiograph shows multilobar consolidations. Although awake and
alert, he appears visibly distressed and has marked accessory muscle use. Apart
from antibiotics and resuscitation for sepsis, which of the following is the next
best step for management of his respiratory failure?

,A. Trial of noninvasive mechanical ventilation by face mask
B. Intubation and initiation of invasive mechani - CORRECT ANSWER ✔✔ - B
A 56-year-old man is admitted to the ICU for pneumonia. He is intubated, with the
following settings: assist control, tidal volume 550 mL, respiratory rate 12
breaths/min, positive end-expiratory pressure 5 cm H2O, FIO2 1.0. Vital signs are:
temperature 38.7°C (101.6°F), heart rate 122 beats/min, respiratory rate 20
breaths/min, blood pressure (BP) 88/46 mmHg, SpO2 97%. A central venous line
and arterial line have been placed. He has been started on broad-spectrum
antibiotics. Which of the following is a clinical indicator that he would benefit
from further fluid resuscitation?
A. Heart rate persistently greater than 90 beats/min
B. Passive leg raise resulting in at least 20% increase in systolic BP
C. Urine output of less than 0.5 mL/kg/hour
D. Systolic BP less than 90 mm Hg - CORRECT ANSWER ✔✔ - B
A 75-year-old man with a history of hypertension is evaluated in the emergency
department for nausea, vomiting, and abdominal pain. He is lethargic but can
answer questions appropriately. His pulse is 130 beats/min, blood pressure 70/30
mm Hg, and respiratory rate 28 breaths/min. On physical examination, he is
noted to have dry
mucous membranes, poor capillary refill, and a distended abdomen with rebound
tenderness. Arterial blood gas analysis reveals: pH 7.32, PCO2 28 mmHg, PO2 74
mm Hg, bicarbonate 13 mmol/L. Serum lactate is 8.0 mEq/L. Which of the
following findings has been shown to correlate with a worse prognosis in a
patient with this clinical
picture?
Pg. 2
, A. Hypotension
B. Acidemia on blood gas analysis
C. Elevated serum lactic acid
D. Tachypnea - CORRECT ANSWER ✔✔ - C
A 65-year-old man is septic, with perforated diverticulitis. He undergoes emergent
colectomy with creation of a colostomy. Multiple areas of purulence are identified
in the peritoneal cavity. Postoperatively, he continues to be febrile and
hypotensive. Chest radiograph is clear. Central venous pressure is 18 mm Hg, and
hemoglobin is 13g/dL. Which of the following vasoactive drugs is most
appropriate to administer next?
A. Epinephrine
B. Phenylephrine
C. Norepinephrine
D. Dobutamine - CORRECT ANSWER ✔✔ - C
A 76-year-old woman with a history of congestive heart failure and hypertension
is admitted with altered mental status and mild upper respiratory symptoms.
According to family, her mental status has been gradually declining over the past
three to four days. Because of generalized weakness and upper respiratory
symptoms, she has had a limited amount of food and drink for the past 72 hours.
Her home medications include metoprolol, lisinopril, and furosemide. Her family
states that she has been compliant with these medications. On physical
examination, vital signs are: heart rate 118 beats/min, blood pressure 96/53 mm
Hg, respiratory rate 14 breaths/min, and oxygen saturation 98% on room air.
Other findings included dry mucous membranes, poor skin turgor, and the
absence of jugular venous distention. Pulmonary examination is clear on
