19
Q

21
Q

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

A

22
Q

Name one contraindication to hetastarch administration?

A

23
Q

24
Q

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

A

25
Which intra-op physiologic changes most often causes prolonged duration of action of a non-depolarizing muscle relaxant?
Temperature
26
During induction of anesthesia, what breath-to-breath end-point are you trying to achieve with bag-and-mask ventilation
Good tidal volumes
27
If aseptic technique is employed consistently, how long can a multidose drug vial continue to be used?
Until its expiration date
28
Which IVFs are contraindication for dilution of PRBCs or contiguous administration with PRBCs?
LR
29
Which IV fluids are relatively contraindicated in patients with ESRD?
LR
30
What are the normal values for prothrombin time?
11-15 seconds
31
What is the effect of an undersized BP cuff on the BP reading?
It will overestimate the pressure
32
What are the difference in arm vs. leg BP measurements?
BPs taken on the leg will read higher pulse pressures, higher systolics and higher diastolics (systolic increases more than diastolic)
33
How do you calculate transmural CVP?
Trans CVP=Direct CVP - (f x Paw) | *convert cmH2O to mmHg
34
What is the osmolarity of saline 3%?
1027 mOsm
35
What is an example of a hypo-osmolar crystalloid IV solution?
LR
36
What peak airway pressure should you stay below during BMV to avoid insufflating the stomach?
20cmH2o
37
What attribute of CVP catheters is associated with increasing risk of infection?
Increasing number of lumens
