Shown below are five curves that represent the distribution of molecular speeds of five different gases at the same temperature and pressure, each in a separate 10 L container. The gases are H2, CH4, He, SF6, and N2. Complete the statements so that they are true.   a. The gas represented by [drop1] has the largest fraction of molecules traveling at the most probable speed. b. Curve [drop2] corresponds to N2. c.  All of the gases represented have the same [drop3]. d.  Gas [drop4] has the greatest density. e.  Decreasing the speed of the molecules will [drop5] the pressure.

3. (WCSP[x], 6 points) Draw two constitutional isomers using bond line structure having the formula C4H8O.  Use two different functional groups and label them by name.   Enter the number of sigma bonds in one isomer below:

The nurse calculates his RASS score to be -4 and his CPOT score to be 0 (zero).  Which of the following would be the best pain, agitation, delirium regimen for TJ? (see RASS and CPOT tables on separate sheet)

Case 5 – Use for questions 65-71 JB is a 35-year-old female (132 kg, BMI 42) who was admitted to the ICU following a highway speed motor vehicle accident.  The patient’s blood alcohol content upon arrival to the emergency department was 0.32% (four times the legal driving limit).  The patient sustained multiple orthopedic injuries from the accident, requiring several visits to the OR during her first 48 hours of admission.  The patient does not have any past medical history on file.  However, her family mentions that she regularly consumes 5-6 alcoholic beverages a day.  On day three of admission, when propofol is turned off for the patient’s spontaneous awakening and breathing trial, she becomes extremely agitated and delirious.  After some discussion on rounds, the medical team believes the patient is going through severe alcohol withdrawal.

Case 3 – Use for questions 50-59 TJ is a 51-year-old male (100 kg, BMI 35) with a history of end stage liver disease and cirrhosis with ascites due to primary biliary cirrhosis.  He has been non-compliant with his home medications.  He presented to the emergency department at the hospital in Backwoods, WI with respiratory distress and a GI bleed.  He states he doesn’t drink or use tobacco products.  Due to impending respiratory failure, he was intubated using RSI at the referring hospital, started on a midazolam infusion, flown to your hospital, and directly admitted to the ICU.  In your ICU, his vitals were: HR 115 bpm, BP 87/50, RR 22 bpm; his labs were: PaO2=96 on 100% FiO2, Hct=16 (normal range 34-46%), Hgb=5.2 (normal range 11.6-15.6), SCr=5.6 (baseline 1.2), AST=245 (normal range 0-40), ALT=356 (normal range 13-59), TBili=17.3 (normal range 0-1.4), INR=1.6 (normal range 0.9-1.2). AST, ALT, and TBili are consistent with PCP visit 3 months ago.

The team intubated DF.  The patient is moving around, and the team wants to give something now that she is intubated.  Her current CPOT = 3 and her RASS = 0 (see RASS and CPOT tables on separate sheet).  What is the most appropriate medication to recommend first-line?
