What is opisthotonus
State of severe hyperextension and spasticity in which an individual’s head, neck and spinal column enter into full arching
When arterial pressure is monitored using a catheter in the dorsalis pedis artery instead of radial, what effect will be seen in the dorsalis pedis measurments?
Systolic raises, diastolic falls, pulse pressure widens

Over 40
A patient with a pulmonary artery catheter in place is suspected of having tricuspid regurgitation. How would you confirm this?
Look at CVP waveform in right atrium
When electrocardiography is used to position a central venous catheter, entry of the catheter’s tip into the right atrium would be indicated by what appearance on the ECG
Biphasic P waves
After successfully placing an introducer into a patient’s left internal jugular vein, the tip of the PA catheter is introduced into the introducer. How far should the PA catheter be advanced before the balloon is inflated?
20cm
Once you have donned sterile gown and gloves, how must your arms and hands be positioned?
Above the waist
Which accessible arterial sites are NOT appropriate for long-term arterial cannulation? Why?
Femoral artery due to risk of infection
Which arterial sites can NOT be cannulated?
- Carotid
- Brachial
What would a normal NMB motor threshold be for an anesthetized, euthermic patient?
15mA
What initial dosage infusion rate for norepinephrine would be most efficacious and safe to produce an increase in both SVR and MAP?
5mcg/min
If general anesthesia is being maintained with isoflurane in a mixture of nitrous oxide 1.5L/min and oxygen 1.5L/min, what determines the partial pressure of the isoflurane being administered?
Temperature
A 48 year old women with CAD is undergoing general anesthesia for laparoscopic cholecystectomy when she begins having multifocal PVCs. What drug and dose should be administered first to treat this problem?
Lidocaine 1mg/kg
During a central venous access procedure, the carotid artery is cannulated instead of the jugular vein. BP is 116/80mmHg. How high in cm will blood rise in the IV extension set tubing?
Calculate patient’s MAP and convert to cmH2O. This patient’s MAP is 92mmHg which is 125cmH2O
How should instruments coming in contact with a patient’s mucosa be cleaned
High disinfection
How should you suture a CVP catheter to a patients skin
Suture it to their dermis and epidermis
