To say that a rule should be prescriptive means that it should

Despite not being recommended as a treatment for ARDS prior to COVID-19, which alternative treatment now shows some evidence of reduced mortality?

Based on Video Lesson 9, describe the difference between an explicit rule and an implicit rule. Use an example of each type of rule to make your distinction clear (Worth Six Points).

You are assisting a pulmonologist with a thoracentesis. The physician suspects the patient has a chylothorax. What color would the fluid be if the physician is correct?

The following ABG results are obtained while a patient is on mechanical ventilation and an FiO2 of 0.5 pH 7.21    PaCO2 65 mmHg    PaO2 75 mmHg    HCO3- 28 mEq/L            Calculate the P/F ratio

A 45-year-old male with an IBW/PBW of 75 kg has been diagnosed with ARDS. The maximum tidal volume (Vt) the patient should be placed on is:

Which network is time-consuming because of the necessity of repeating messages so that each member hears it directly?

Using the patient scenario from the previous question:  A female was admitted to the ICU yesterday due to acute onset of dyspnea and hypoxemia secondary to pneumonia. Last night, the patient required emergent intubation due to hypoxemic respiratory failure. The patient is now on full ventilatory support, PEEP of 8 cmH2O, and a 0.75 FiO2. This morning’s radiologic and laboratory results reveal the following: Influenza A and B:  positive CXR:  presence of diffuse, bilateral opacities worsened from previous exam consistent with pneumonia; ETT adequately positioned. There is no evidence of heart failure, cardiomegaly,  or pleural effusions. No other active disease processes are present. ABG:  pH 7.32    PaCO2 50 mmHg    PaO2 50 mmHg    HCO3- 24 mEq/L   Later, during ICU rounding, the pulmonologist asks your opinion of the patient’s current condition. The most appropriate response is:

In reference to the CXR below, which of the following findings are present? 325 L pleural effusion.jpg 

Which of the following is the most appropriate treatment of recurrent pleural effusions?
