*also, be cautious when used with patients undergoing MRI with ferromagnetic implants, which may include pacemakers/AICDs
In a 6 year old, the appropriate depth of an endotracheal tube is:
15
(age/2) + 12
as compared with plasma osmolality, hypertonic crystalloid solutions include
D5 0.45 NS = 400 mOsm
normal plasma osmolality = 280 -290
plasma osmolality of LR and D5 0.25 NS
273 and 355
selective adrenergic stimulation of B2 receptor results in
increased insulin secretion bronchodilation salivary gland secretion decreased upper GI motility gluconeogenesis pupillary dilation detrusor muscle relaxation
s/s associated with hypercortisolism include
metabolic alkalosis, osteoporosis, central obesity, HTN, weakness, bruising
s/s associated with mineralocorticoids
fluid retention
hypokalemic alkalosis
pancreatic somatostatin producing cells in the Islets of Langerhans are:
delta cells
Name the four types of cells in the islets of langerhans
alpha = glucagon
beta = insulin
delta = somatostatin
PP cells = pancreatic polypeptide
CHD associated with right - to - left shunting includes
(CYANOTIC)
tricuspid atresia hypoplastic left heart syndrome TOF pulmonary atresia transposition of great vessels truncus arteriosus single ventricle double outlet ventricle
recommended maximum leakage current in OR
10 uA
How is hypoxemia treated most effectively during OLV?
periodic inflation of the collapsed lung (1)
early ligation of the ipsilateral PA (2)
CPAP to collapsed lung (3)
what paralytic should be used for maintenance in ESRD during a lap. hysterectomy?
cisatracurium
- vec = active metabolite excreted renally
- roc = variable duration and renal excretion
Sympathetic blockade during acute herpes zoster has been shown to:
reduce the incidence of postherpetic neuralgia; reduce analgesic requirements overall

745 PSIG
once it falls below 745, there is only 400 L left
the formation of metanephrine is the result of:
CATECHOL-O-METHYLTRANSFEREASE METABOLISM OF EPI
COMT metabolizes epinephrine –> metanephrine and norepinephrine –> normetanephrine
MAO metabolizes metanephrine & normetanephrine –> VMA
