Neuromuscular blocking drugs may be beneficial in the management of a patient with ARDS because of which one of the following?

A 68-year-old woman with HIV is admitted to the ICU with respiratory failure secondary to pneumocystis pneumonia, requiring intubation and mechanical ventilation. A chest CT scan was performed before intubation and demonstrated cystic changes throughout the lungs, thought to be a sequela of past pneumocystis infection, with superimposed diffuse ground glass opacities. Her ventilator is set on volume assist-control, TV 6 mL/kg, respiratory rate 16 breaths per minute, FiO2 0.8, and PEEP of 10 cm H2O. On day 2 of her critical illness, her ventilator suddenly alarms for elevated peak pressures. She is observed to be deeply sedated and breathing passively on the ventilator. The peak pressure has risen from 25 cm H2O several hours before 50 cm H2O. The patient has simultaneously experienced oxygen desaturation from 95% to 90%. She is otherwise hemodynamically stable. A chest radiograph is ordered. An inspiratory hold maneuver is performed and her plateau pressure is 20 cm H2O. Which of the following is the MOST LIKELY explanation for this acute event?

The proper position for chest tube placement in a patient with a pneumothorax is:

36. Which food is high in monounsaturated fat?  

26. Which finding suggests severe malnutrition?  

A 38-year-old, 155 cm, 50 kg, previously health female presents to the ICU with altered mental status, tachycardia, hypotension, and high fever. She is intubated for airway protection. Her laboratory test results reveal a markedly elevated T3 and T4 level with a decrease in thyroid-stimulating hormone level consistent with thyroid storm. Her arterial blood gas shows a pH of 7.24, PaO2 of 80, PaCO2 of 52, and HCO3 of 22. Her ventilator settings are volume control, tidal volume of 350 mL, respiratory rate of 14, positive end expiratory pressure (PEEP) of 5, FiO2 of 50%. Which of the following is the next appropriate step in management?

43. What is the best way to prevent foodborne illness?  

50. Which food allergy is most common in infants but often outgrown?  

14. Which hormone increases metabolism during stress?  

44. Which population is most at risk for foodborne illness? (Select all that apply)
