what is the quick rule of thumb for determining how long it will take for a drug to reach 87.5% of steady state if given via continuous infusion

rule of thumb: continuous infusion of a drug will cause it to reach 50% of steady state after one half-life, 75% of steady state after two half-lives, 87.5% of steady state after three half-lives


how do you calculate filtration fraction



what are the side effects of sulfalazine

anorexia, headache, nausea, irreversible oligospermia, hypersensitivity rxns, Steven-Johnson syndrome, exfolative dermatitis, toxic epidermal necrolysis


organophosphates (found in pesticies) have what mechanism of action and how is exposure to organophosphates treated

ACh esterase inhibitors;
treated with pralidoxime


what is the alveolar ventilation equation

PACO2=production of CO2/ alveolar ventilation


Rosenthal fibers (eosinophilic corkscrew fibers) and a cyst with a nodule in the cerebellum is characteristic of what neural neoplasm

pilocytic astrocytoma


what uniquely characterizes each of the Tanner stages in women

1: elevation of the papilla of the breast
2: enlargement of areola, coarsening of pubic hair
3: axillary hair grows in, peak height increase, acne
4: areola forms secondary mound on breast
5: adult breast contour; full pubic hair spread to medial thigh


what is the alveolar gas equation



which AChE inhibitors are used to treat myasthenia gravis

what are the two ways that RBF and GFR are autoregulated in order to keep them constant between pressures of 80-180mmHg

1. myogenic response: increase blood pressure triggers contraction of smooth muscle and decreased blood pressure triggers relaxation
2. macula densa causes vasoconstriction in response to increased BP and stops vasoconstricting effects in response to low BP


a herniated disc compressing L5 would cause what symptoms

inability to extend the toe, inability to dorsiflex the foot (foot drop), loss of sensation over dorsum of the foot


which anatomic structure lies directly posterior to the manubrium

the left brachiocephalic vein


what is Chvostek's sign and how would acute pancreatitis cause this sign to be able to be elicited

Chvostek's sign= tapping on the face near the maxilla causes ipsilateral facial twitching; sign of hypocalcemia

pancreatitis causes hypocalcemia via saponification with fatty acids


what are the surface markers used to identify natural killer cells

CD16 and CD56
