Q

Central Diabetes Insipidus is associated with

_____

_____

A
  • ​A problem with the posterior pituitary
    • decreased ADH production
  • ​Caused by damage to the hypothalamus or pituitary
    • ​hypothalamus produces ADH which is then released by the poteriour pituitary

Q

Polycystic kidney disease is a cystic genetic disorder of the kidneys

Adult form is _____ inheritance

Child form is _____ inheritance and _____ mortality

A

Adult form is dominant inheritance

Child form is recessive inheritance

17
Q

_____ are the most common cause of upper urinary tract obstructions

A

Renal Calculi

18
Q

Cysteine stones are associated with _____

A

Rare cysteine metabolism disorder

19
Q

Calcium(oxalate or phosphate) stones are associated with ____

A

Excess calcium and parathyroid dysfunction

20
Q

Uric acid (urate) stones are associated with _____

A

Gout

21
Q
  • Renal ischemia caused by
    • obstruction of urine outflow from the kidneys
      • ureter (calculi and strictures)
      • bladder (tumors or neurogenic bladder)
      • urethra (prostatic hyperplasia)
A

Post-renal disease

22
Q
  • Released from the posterior pituitary
  • acts on the renal tubules to allow for water reabsorption that depends upon the formation of a sat garadient by the loop of henle
A

ADH

23
Q
  • Characterized by
    • hematuria, azotemia (presence of nitrogen substance in the blood), proteinuria, edema, and hypertension
  • May occur as a primary disorder such as acute poststreptococcal glomerulonephritis
    • or secondary to lupus
A

Nephritic Syndrome

24
Q

The renin-angiotensin system results in release of two important factors

A

Angiotensin II- potent vasoconstrictor

Aldosterone from the adrenal cortex- facilitates in sodium reabsorption

25
Q
  • Characterized by massive loss of proteinuria and lipiduria
  • leads to hypoalbunemia and edema
    • shift in colloid osmotic pressure
    • fluid accumulation may be in tissues​​
  • pleural effusions and pulmonary edema
  • can cause hyperlipidemia due to the liver synthesizing lipids as it tries to compensate for albumin loss
A

Nephrotic syndrome

26
Q
  • Byproduct of protein metabolism
  • measures amount of urea in blood
A

BUN (Blood urea nitrogen)

27
Q

Refers to the clinical syndrome of renal failure with azotemia

Includes azotemia as well as acidosis, hyperkalemia, hypertension, anemia, and hypocalcemia

_____ may be indicated as treatment

A

Uremia

Dialysis may be indicated for treatment

Widespread dysfunction in other body systems including altered CNS function, neuropathy, ulceration of GI tract, N/V/HTN, skin discoloration, electrolyte imbalances, poor blood clotting, immunosuppression, pericarditis

28
Q
  • Drug that inhibits aldosterone
  • blocks Na reabsorption
  • increases K retention
A

Potassium sparing diuretics (spironolactone)

29
Q

Causes of Nephrogenic Diabetes Insipidus

A
  • Drugs such as lithium
  • hypercalcemia
  • Polycystic kidney disease

All 3 alter the ability of ADH to work

30
Q

Secondary effects of polycystic kidney disease include cysts to _____

A
  • Liver and pancreas
  • Rarely the heart and brain
31
Q

Central Diabetes Insipidus may be controlled by ____

A

Giving a modified form of vasopressin such as desmopression or DDAVP
