0

Cyclosporine most commonly causes toxicity in what organ?

Kidneys

1

Things to do within 3 hours of severe sepsis:

Measure lactate
Blood cultures prior to atbx
Broad spectrum atbx
30 mL/kg of crystalloid

2

Plexus block to relieve visceral pelvic pain

Superior hypogastric plexus block

3

Occurrence of spontaneous bleeding in patients with HIT

Rare

4

Medications that induce p450 system

Carbamazepine
Dexamethasone
Modafinil
Omeprazole
St. John's wort

5

Transfusion associated graft vs host disease occurs most commonly in what age group?

Patients over age 60 yrs, developing 1-6 weeks after transfusion

6

Induction drug associated with increased seizure duration for ECT

Etomidate

7

Preop test that is best predictor of post thoracotomy morbidity and mortality

VO2: Maximal oxygen consumption
< 12mL/kg/min = 7x risk
< 1 flight of stairs = < 10mL/kg/min
5 flights = > 20mL/kg/min

8

Traditional cutoff for preop paCO2 level for pulmonary resection

paCO2 > 69 mmHg

9

Single most important cause of morbidity and mortality in patients with subarachnoid hemorrhage who survive initial bleed

Delayed cerebral ischemia, presenting 3-14 days after initial bleed

10

Only drug demonstrating benefit to subarachnoid hemorrhage patient

Nimodipine

11

Adrenergic agonist that is metabolized by lungs

Norepinephrine

12

Mechanism of fenoldopam

Selective dopamine type 1 receptor agonist that decreases renal vascular resistance and increases renal blood flow

13

Only intervention with documented efficacy in resolving the inability to ventilate with opioid induced rigidity

administration of neuromuscular blocking drugs

14

Single most important stimulus for hypoxic pulmonary vasoconstriction

PAO2, partial pressure of oxygen at the alveoli

15

Drugs to treat wide complex SVT associated with WPW

Lidocaine, amiodarone, procainamide

16

Why is aspirin contraindicated in patients with hyperthyroidism

It inhibits binding of thyroid hormone and can increase levels of free t4 and t3

17

Conditions that increase carbon monoxide diffusion capacity

Exercise, asthma, polycythemia, pulmonary hemorrhage, left to right intracardiac shunting

18

What causes exacerbation of multiple sclerosis (MS) symptoms?

Increased body temperature, emotional and physiological stress

19

Pretreatment with what medication may decrease frequency of abnormal movements during induction?

Fentanyl

20

Only consistent method to prevent dementia or postop cognitive dysfunction (POCD)

Identifying patients at risk preoperatively with geriatric consultation

21

Cherry red colored blood occurs when carbon monoxide levels are greater than?

40%

22

Treatment of choice for thrombotic thrombocytopenic purpura (TTP)

Plasma exchange

23

Why is succinylcholine contraindicated with Guillain-Barré syndrome (GBS) patients?

Hyperkalemia risk is increased due to proliferation of post synaptic receptors
