18
Q

What is the internal diameter of an anesthesia face mask connector?

A

22mm

19
Q

What observational assessment is the best means for assessing effectiveness of bag-and-mask ventilation?

A

Below what MAC level will sevoflurane not increase heart rate?

A

1.5

21
Q

Comparing blood pressure measurements taken on an upper arm and the ispilateral calf, how will the systolic and diastolic values compare?

A

Systolic increases more than diastolic

22
Q

Name one contraindication to hetastarch administration?

A

Allergic reaction

23

A

3, 4

24
Q

For vascular access procedures, a safe, effective alternative preparation for an iodine-allergic patient would be…

A

Chlorhexadine 4%

25
Q

Which intra-op physiologic changes most often causes prolonged duration of action of a non-depolarizing muscle relaxant?

A

Temperature

26
Q

During induction of anesthesia, what breath-to-breath end-point are you trying to achieve with bag-and-mask ventilation

A

Good tidal volumes

27
Q

If aseptic technique is employed consistently, how long can a multidose drug vial continue to be used?

A

Until its expiration date

28
Q

Which IVFs are contraindication for dilution of PRBCs or contiguous administration with PRBCs?

A

LR

29
Q

Which IV fluids are relatively contraindicated in patients with ESRD?

A

LR

30
Q

What are the normal values for prothrombin time?

A

11-15 seconds

31
Q

What is the effect of an undersized BP cuff on the BP reading?

A

It will overestimate the pressure

32
Q

What are the difference in arm vs. leg BP measurements?

A

BPs taken on the leg will read higher pulse pressures, higher systolics and higher diastolics (systolic increases more than diastolic)

Trans CVP=Direct CVP - (f x Paw)

*convert cmH2O to mmHg

A

LR

36
Q

A

20cmH2o

37
Q

What attribute of CVP catheters is associated with increasing risk of infection?
