A 36-year-old female patient with a history of asthma is admitted to the ICU from the emergency department. Her respirations are 30, very labored, with accessory muscle use and bilateral inspiratory and expiratory wheezing. There is bilateral hyperresonance during chest percussion. A blood gas taken in the ICU after 1 hour of continuous aerosolized albuterol (15 mg) reveals: pH 7.38, partial pressure of carbon dioxide (PaCO2) 42 mm Hg, partial pressure of oxygen (PaO2) 53 mm Hg, oxygen saturation (SaO2) 88%, bicarbonate (HCO) 25 mEq/L with nasal cannula 6 L/min. The patient is 5’5″ and weighs 135 lb. The most appropriate action at this time is which of the following?

The ventilator mode that would be most appropriate to iatrogenically induce hyperventilation to manage a closed head injury patient with severely elevated intracranial pressure (ICP) is which of the following?

What  were the foreign policy objectives of the Russians during the nineteenth century? (NOTE: Answer should be 50-75 words)

A patient with acute respiratory distress syndrome has a plateau pressure (Pplat) of 30 cm H2O and a peak inspiratory pressure of 39 cm H2O. VT is 0.7 on VC-CMV. The decision is made to switch to PC-CMV (PCV) to keep pressures at a safe level. What pressure would you set and why?

The mechanical ventilator event that is considered potentially life-threatening or a level two event is which of the following?

Promoter A that controls gene C and promoter B that controls gene D are both recognized by the σ70 subunit in E. coli. When the σ70 subunit is active, the transcription of gene C is initiated once every 30 seconds on average and the transcription of gene D is initiated once every 3 seconds on average. Which promoter has a greater affinity for the σ70 subunit?
