What is the role of the renal system in regulating potassium ion concentration in the extracellular fluid [ECF]? a. Kidneys filter and excrete excess potassium ions into the urine. b.Kidneys respond to aldosterone by not excreting any potassium ions into the urine. c.Kidneys reabsorb all potassium ions into the urine. d. Kidneys excrete water molecules through aquaporins in the collecting duct.
Hello,
can you look over the ones I answered and I do need help with the last one please. Thank you so much!
Identify 3 organs susceptible to the adverse effects of hypokalemia.
- 1. Skeletal muscle weakness
- 2. Smooth muscle atony
- 3.Cardiac dysrhythmias
Identify the cardiac dysrhythmia most associated with hypomagnesemia.
The cardiac dysrhythmia most associated with hypomagnesemia is Torsades de pointes.
Hyperkalemia is defined as elevated ____________________________.
a.calcium levels in the plasma.
b.potassium levels in the extracellular fluid.
c. sodium levels in the extracellular fluid.
d. phosphate levels in the cytoplasm.
b. Potassium levels in the extracellular fluid.
