Renal Flashcards
1
Q
Renin - Regulation, production, effect
A
- B1 input, Low BP, Low Na
- JG cells
- Angiotensinogen -> AT1
2
Q
Aldosterone - reg, prod, effect
A
- AT2
- Adrenal cortex
- Up Na via principal cell channel & pump
- Down K and H
3
Q
ADH - reg, prod, effect
A
- AT2
- Posterior pituitary
- Aquaporins in Distal collecting duct
4
Q
ANP - reg, prod, effect
A
- Cardio distention
- Heart
- Up GFR & Na filtration, no Na reabsorption
5
Q
NSAIDs effect on kidney
A
Inhibit renal PG, constrict afferent arteriole, Down GFR
6
Q
FF equation
A
- FF = GFR/RPF = creatinine/PAH
- normal FF=0.2
7
Q
Winter’s formula
A
P.CO2 = 1.5(HCO3) + 8 +/- 2
8
Q
K levels affecting ECG (low, high)
A
low - U waves, flattened T waves
high - wide QRS, peaked T waves
arrhythmias in both
9
Q
Hypercalcemia clinical (4)
A
Stones - kidney
Bones - pain
Groans - abdominal pain
Overtones - psychiatric instability
10
Q
Hyperkalemia causes (6)
A
DO Insulin LAB
- Digitalis
- hyperOsmolatiry
- insulin deficiency
- Lysis of cells
- Acidosis
- B-adrenergic antagonist
11
Q
Hypokalemia cause
A
Insulin (stimulate Na/K pump)
