Which patient would most likely be prescribed sodium nitroprusside [Nitropress]?

As part of the standard operating procedure on an older analyzer, one of the monthly activities includes running multiple samples multiple times using the same kit lot of reagent.  This is called: 

Control values are running outside the acceptable range of a stable analyzer for the last 5 days.  The scientist in charge has troubleshooted possible causes and has discovered that the pipette used in the reconstitution of the controls needs calibration.  This represents an error in which phase of laboratory analysis?

The purpose of linear regression is to: 

Two methods are compared for a method validation.  There are 20 concordant pairs of results and 5 discordant pairs of results between the two methods.  What is the test-retest reliability? (C-D)/(C+D)  (20-5)/(20+5) = 

An instrument has a probe error in the middle of running QC.  Both the low and high controls are outside acceptable limits.  This represents an error in which phase of laboratory analysis?

To establish linearity, a certain number of data points are needed, but all points leading up to it also have different purposes.  For this question, correlate the number of points to their overall purpose. 

5’9″ Female intubated patient VC VMV VT 400 mL RR 14 bpm FIO2 30% PEEP 5 cm H20 Ti 1.3 sec descending flow What is her targeted MV (please round up to one past decimal point. For example, 9.87 would be 9.9 LPM)answer in this format X.X LPM

An 18-year-old, 5’6″, 125 lb female patient was admitted to the hospital 2 days ago for spinal meningitis. She developed sepsis and suffered hypercapnic respiratory failure. The patient was intubated and placed on volume-controlled continuous mandatory ventilation (VC-CMV), respiratory frequency (f) 12 breaths/min, tidal volume (VT) 500 mL, positive end-expiratory pressure (PEEP) 5 cm H2O, fractional inspired oxygen (FIO2) 0.40. Twenty-four hours later, the patient’s oxygen requirements had dramatically increased and her lung compliance had dramatically dropped, while her chest X-ray showed the development of bilateral fluffy infiltrates. The most appropriate actions to take include which of the following?

Sigh breaths could be beneficial during which of the following situations?
