Hyperkalemia Flashcards
1
Q
Hyperk treatment
A
IV insulin (10 unit IV insulin bolus) and 50g dextrose IV calcium gluconate or chloride Sodium bicarb 50-100 mEq IV LOOP diuretics -increase K elimination Hemodialysis- increase K elimination Patiromer Oral suspension
2
Q
Hyperk s/sx
A
Peaked T waves on ECG ; similar to hypokalemia
3
Q
BRASH Sydrome stands for:
A
Bradycardia Renal failure AV node blocker usually due to BB, verapamil, diltiazem Shock Hyperkalemia
4
Q
What is likely to cause bradycardia?
A
Hyperkalemia plus AV nodal blockers
5
Q
BB cleared by the kidneys
A
Atenolol, nadolol
6
Q
Bradycardia treatment
A
Mechanism: decrease HR= decrease CO
IV Ca
Epi/isoproterenol infusion at 2-10 mcg/min
7
Q
Renal treatment
A
Mechanism: decrease BP= decrease RBF= decrease GFR
Increase perfusion
Hold nephrotoxins
8
Q
AV node blocker treatment
A
Stop the AV blocker
Also stop ACEI/ARBs
9
Q
Shock treatment
A
Mechanism: decrease CO —> decrease BP
Increase BP WITH pressors or LR or bicarb
10
Q
Hyperkalemia treatment
A
IV Ca 5 U insulin IV Dextrose: glucose <250 Albuterol 10-20 my nebulized IV Diuresis —> key to K elimination 1. Loop diuretic 2. Thiazide 3. +/- acetazolamide 4. +/- fludrocortisone
