17
Q

Perioperative risk factors for acute renal failure

A

Age > 59, emergent surgery, chronic liver disease, BMI > 32, high risk surgery, peripheral vascular disease, severe COPD

18
Q

Electrolyte abnormalities with renal failure

A

Elevated electrolytes: K, phos, Mg

19
Q

Hemodialysis complications

A

Cerebral edema, headache, nausea, hypercalcemia, fever, arrhythmias, bleeding, infection, anemia

20
Q

Hyperammonemia is caused by what during TURP

A

Glycine is metabolized to ammonia, leading to encephalopathy

21
Q

Plateau pressure is a measurement of what type of compliance

A

Static compliance

22
Q

Peak pressure is a measurement of what type of compliance

A

Dynamic compliance

23
Q

24
Q

Mechanism of action of bumetanide

A

Loop diuretic, 40 times more potent than furosemide

25
Q

Flumazenil half life

A

7-15 min, shorter than many benzodiazepines, so redosing may be required

Q

Baralyme or soda lime has greater risk of producing carbon monoxide

A

Baralyme

28
Q

What to do if epidural catheter is disconnected.

A

Clean open ends with alcohol, then in sterile technique, cut the catheter before placing new connector piece

29
Q

Dalton’s Law

A

Total pressure exerted by a mixture of gases in a fixed volume is equal to the sum of each gas partial pressure

34
Q

Hepatitis B needle stick prophylaxis treatment

A
