posterior (2) supplies dorsal --- arises from the cerebella arteries and supply sensory
region spinal needles

sprotte, pencan, and whitacre are pencil point
,greene needles has a rounded tip and is also associate with lower incidence of PDPH
• Question
Carcinoid crisis
Correct Answer: tumors typically release GI peptides and vasoactive substances
TX: octreotide, somatostatin, antihistamines, 5ht3, steroids, neo or vaso
• Question

• Question
What drug interferes with the baroreceptor reflex the most?
Correct Answer: Labetalol
when the baroreceptor reflex is intact, low BP should result in high HR
Labetolol is an alpha 1 and non selective beta blocker, ratio of beta to alpha is 7:1.
Labetolol reduces HR and contractility and causes vasodilation

Correct Answer: Zone 4
very limited access with strict supervision

Correct Answer: 3 days
, • Question
how long should NSAIDS be dc prior to sx
Correct Answer: 1 day
• Question
which gas laws are illustrated in the fick equation?
Correct Answer: Graham
Henry
describes the transfer rate of gas through a tissue medium -- rate of transfer directly
proportional to partial pressure (driving force), diffusion coefficient (solubility), and
membrane surface area.
henrys law - amount of gas that dissolves in solution is directly proportional to partial
pressure of that gas over the solution
Graham - states that the rate of gas diffusion is inversely proportion to the square root
of its molecular weight
