Auscultatory crackles would most likely be associated with... A. Asthma B. Airway stenosis C. Pulmonary embolism D. Congestive heart failure
D. Congestive heart failure
What nerves are at risk when NIBP is measured on the upper arm?
Radial and ulnar
What nerve is at risk when the blood pressure cuff is placed too low on the upper arm?
Ulnar
What is the normal lung compliance value? (CL)
200ml/cmh2o
What is the calculation for lung/thoracic compliance?
1/CLT=1/CL + 1/CT
How do you calculate the fraction of applied airway pressure that will be transmitted into the pleural space?
f=CL/(CL+CT)
When does aspiration most often occur?
During induction
For safe, cost-effective preparation for an elective case, how many ETTs should be opened?
1
An otherwise healthy 29-year-old woman is scheduled to undergo BTL. What is a BTL?
Bilateral tubal ligation
An appropriately sized NIBP cuff should be __% of the width of the patient’s upper arm
40
An appropriately sized NIBP cuff should be __% of the length of the patient’s upper arm
80
What is the function of the anesthesia reservoir bag?
To help meet peak inspiratory flow requirements
You should stay below __cmH2O during bag/mask ventilation to avoid insufflating the stomach
20
What is a major contraindication to the placement of a NIBP cuff?
AV fistula
What does the acronym SVC stand for?
Superior vena cava
Which nerve is at risk of injury when a face mask strap is used?
Facial (cranial nerve VII)
What is the internal diameter of an anesthesia face mask connector?
22mm
What observational assessment is the best means for assessing effectiveness of bag-and-mask ventilation?
Chest rise and fall
Below what MAC level will sevoflurane not increase heart rate?
1.5
Comparing blood pressure measurements taken on an upper arm and the ispilateral calf, how will the systolic and diastolic values compare?
Systolic increases more than diastolic
Name one contraindication to hetastarch administration?
Allergic reaction
When performing bag-and-mask ventilation in an adult, which fingers must be applied only to the bony rim of the mandible?
3, 4
For vascular access procedures, a safe, effective alternative preparation for an iodine-allergic patient would be…
Chlorhexadine 4%
Which intra-op physiologic changes most often causes prolonged duration of action of a non-depolarizing muscle relaxant?
Temperature
During induction of anesthesia, what breath-to-breath end-point are you trying to achieve with bag-and-mask ventilation
Good tidal volumes
If aseptic technique is employed consistently, how long can a multidose drug vial continue to be used?
Until its expiration date
Which IVFs are contraindication for dilution of PRBCs or contiguous administration with PRBCs?
LR
Which IV fluids are relatively contraindicated in patients with ESRD?
LR
What are the normal values for prothrombin time?
11-15 seconds
What is the effect of an undersized BP cuff on the BP reading?
It will overestimate the pressure
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)
How do you calculate transmural CVP?
Trans CVP=Direct CVP - (f x Paw)
*convert cmH2O to mmHg
What is the osmolarity of saline 3%?
1027 mOsm
What is an example of a hypo-osmolar crystalloid IV solution?
LR
What peak airway pressure should you stay below during BMV to avoid insufflating the stomach?
20cmH2o
What attribute of CVP catheters is associated with increasing risk of infection?
Increasing number of lumens
