(carbonic acid)
Final products:
Caco3 + naoh
(calcium carbonate and sodium hydroxide)
What is the Aldrete Score and what does it quantify? - correct answer Quantifies
recovery from anesthesia
Drug eluding stent vs metal stent
How long after stent placement should another surgery be delayed? - correct answer
DES: delay surgery for 6 months if possible
Metal stent: delay surgery for a minimum of 30 days
Gastroschisis vs. Omphalocele
,Where do abdominal contents spill out from?
Are abdominal contents covered in a sac?
Which one is more associated with prematurity?
Which one is associated with congenital abnormalities? - correct answer Gastroschisis
-abdominal contents coming from right of umbilicus
-abdominal contents NOT covered by a sac
-happens more commonly with prematurity
-not associated with congenital abnormalities
Ompahlocele
-abdominal contents coming from midline defect
-abdominal contents covered by sac
-associated with congenital abnormalities
Name some drugs that interfere with SSEP monitoring.
What drugs are safe to use when SSEP monitoring is happening? - correct answer
Drugs that impair sseps (decrease SSEP amplitude and increase SSEP latency)
-volatiles, N2O
-propofol
-barbiturates
,-midazolam, diazepam
Drugs that do not impact SSEP monitoring
-ketamine
-dexmeditomidine
-opioids
-droperidol
In a 70 kg patient, figure out how much HCO3- needs to be administered to go from a
serum bicarb level of 20 meq/L to a serum bicarb level of 25 meq/L. - correct answer
1. Goal bicarb level MINUS current bicarb level --> 25- 20= 5 meq/L
2. Multiply 5 by patient weight (kg) and 0.3 (constant) --> 5 x 70 x 0.3= 105 meq/L
3. Divide 105 meq/L by 2 --> 52.5 meq/L
This patient needs 53 meq/L of bicarb to go from 20 to 25.
Mannitol dosing - correct answer 0.25- 1 GRAM/kg
Which chemo agents are alkylating agents, antitumor antibiotics and tubulin binding
agents? - correct answer Alkylating: Busulfan, Carmustine, Cyclophosphamide,
Cisplatin
Antitumor ABX: Doxorubicin, Danorubicin, Bleomycin
, Tubulin Binding: Vinicristine (Vinca alkaloids), taxanes
Where is a lefort II fracture located?
Which lefort fracture is associated with an intact cribiform plate?
Which lefort fracture are nasal intubations contraindicated in? Why? - correct answer
lefort II: upside down V- goes above bridge of nose and under the eye sockets
Lefort 1: intact cribiform plate- nasal intubations are okay because CSF leak is unlikely
Lefort II & III: nasal intubations contraindicated, could have basilar skull fracture
(raccoon eyes, CSF leak likely)
After a tourniquet on a lower extremity is released, what do you expect to see an
increase in on your monitors? - correct answer Increase in ETCO2
Will see a decrease in BP, HR, SVO2, PAP and ph due products of lactic acid
metabolism being released into systemic circulation
How many ml of 0.9% NS needs to be added to 1 ml of 1:1000 epinephrine to make the
concentration 2.5 mcg/ml? - correct answer 1:1000 --> 1000 mg/1000 ml --> 1 mg/ml
