No.

93
Q

Explain the sodium and water balance due to CKD

Sodium excretion increases, with obligatory (bc water follows salt) water excretion leading to sodium deficit and volume loss

94
Q

Explain the potassium balance due to CKD

A

Tubular secretion increases early (hypokalemia, so the potassium in blood decreases) However, once oliguria sets in, potassium is retained

Metabolic acidosis occurs when glomerular filtration rate declines to 30-40%

96
Q

Explain the calcium and phosphate balance due to CKD

A

Decreased renal synthesis of 1,25-(OH)v2, Vitamin D3, and hypocalcemia (due to decrease calcium in gut). The parathyroid released pthormone to compensate
