A patient receiving mechanical ventilation has received Halcion in the last twenty
minutes. The physician orders the institution of spontaneous breathing trials to
commence immediately. Which of the following medications would be most
helpful to the patient?
A. Valium
B. Morphine sulfate
C. Meperidine
D. Romazicon (Flumazenil) - Correct answer-D. Romazicon (Flumazenil)
*In this question the patient is taking a drug called Halcion. The doctor would like
T-piece trials, which means the patient has to breathe on his or her own. Since that

,medication would inhibit breathing, the effect of that medication must be reversed.
Romazicon is the drug that will reverse Halcion.
In preparation for ventilator weaning the physician requests a VD/VT ratio
assessment. Which of the following is needed to determine the deadspace-tidal
volume ratio?
A. single breath nitrogen elimination and capnographic data
B. helium dilution study and single breath nitrogen elimination
C. helium dilution study and an arterial blood gas
D. arterial blood gases and capnographic data - Correct answer-D. arterial blood
gases and capnographic data
*This question is just about knowing what it takes to calculate a VD/VT ratio. You
really only need two things - PO2 and end tidal CO2. End tidal CO2 comes from a
device called a capnograph.
A respiratory therapist is determining a VD/VT ratio. Which of the following is
needed to complete this analysis?

,A. VT and VA
B. FIO2 and PaO2
C. PECO2 and PaO2
D. PetCO2 and PaCO2 - Correct answer-D. PetCO2 and PaCO2
*There are two things required to determine a VD/VT ratio - end tidal CO2 and
PaCO2.
Which of the following is LEAST likely to promote the spread of nosocomial
infection in a hospital?
A. use of unit dose medication
B. poor hand washing among staff
C. frequent disconnection of a ventilator circuit
D. changing small volume nebulizer equipment every 48 hours - Correct answer-A.

, *The best option is to use unit dose medication. The use of multiple-dose bottles of
medication used to be more prelavent. When doing so the dropper stem of the
medication bottle could touch the internal surface of the nebulizer, possibly picking
up and depositing pathogenic organisms. Changing the nebulizer every 48 hours
may also be helpful but not as effective at preventing nosocomial infections. The
other options in this question are likely to increase nosocomial infection rates in
hospitals.
Which of the following can be used to estimate the level of Hemoglobin?
A. Theophylline level
B. RBC
C. C(a-v)O2
D. PAO2 - Correct answer-B. RBC
*There is a relationship between hematocrit, hemoglobin, and red blood cell count.
Each of these items have a multiplier of three in common. For instance, normal
RBC is about 5. Hemoglobin can be estimated by taking the RBC and multiplying
is by 3. That would give you a hemoglobin of 15. Hematocrit can be estimated by
