MCAT question #52-54

I cannot reveal my source, but I once again am privy to esoteric wisdom. The following is a question I have obtained from the Medical College Admission Exam (MCAT):

#52:

Your an ER doc and in comes a patient complaining of dysnpea. He has a fistula on his left arm and his right arm is in a sling.  The patient has 3lpm nasal cannula at home, and is presently hooked to a flowmeter at 3lpm.  The patient presents with the following vitals:

• Blood Pressure 188/93
• Heart Rate 101
• Lung sounds: Crackles in bases, diminished
• Spo2 is 88% on 3lpm

What is the first thing you do?

• a)Call respiratory therapy STAT to do a Duoneb breathing treatment
• b)Check to make sure the nasal cannula is working properly
• c)Increase oxygen until you maintain an SpO2 of 92% in order to oxygenate the patient
• d)Order Lasix

#53:

The  respiratory therapist arrives to give the patient described in question #45 above a breathing treatment.  The first thing he does is fix the nasal cannula so that it's no longer oxygenating the patient's cheek.  The SpO2 shoots up to 98%.  The respiratory therapists asks if the breathing treatment is still needed.  What do you say?

• a) Of course I still want a breathing treatment, the patient is short of breath, isn't he?
• b) No, the patient appears to be wet.  I'll order Lasix and monitor blood pressure
• c) Order Q2 hour treatment you arrogant condescending son of a b)*&^tch trying to show me off will you???
• d) Ignore the respiratory therapist because you already gave an order

#54: 

Continuing on with our patient in question #45 above, there is one more series of procedures we can order to piss off the respiratory therapist.  Hint:  There's no easy access to arteries.

• a) Sepsis order set (includes EKG and ABG)
• b) Another breathing treatment
• c) Another breathing treatment and EKG and ABG
• d) Order Lasix
