Which statement indicates a patient understands the purpose of antidiuretic hormone (ADH)?
"It increases my urine output."
"It reduces the reabsorption of sodium in my kidneys."
"It decreases water reabsorption in my kidneys."
"It helps retain water to maintain my blood pressure."
The Correct Answer is D
(A) "It increases my urine output." ADH reduces urine output by increasing water retention.
(B) "It reduces the reabsorption of sodium in my kidneys." ADH affects water reabsorption, not sodium regulation.
(C) "It decreases water reabsorption in my kidneys." ADH increases, not decreases, water reabsorption.
(D) "It helps retain water to maintain my blood pressure." ADH promotes water reabsorption in the kidneys, reducing urine output and increasing blood volume, which helps maintain blood pressure.

Severe Dehydration: Prerenal
Decreased blood flow to the kidneys due to low volume.
Sepsis: Prerenal
Hypotension from systemic infection reduces kidney perfusion.
CHF (Congestive Heart Failure): Prerenal
Reduced cardiac output leads to inadequate renal perfusion.
Benign Prostatic Hyperplasia (BPH): Postrenal
Urinary outflow obstruction causes back pressure on the kidneys
Renal Calculi (Kidney Stones): Postrenal
Blockage in the urinary tract prevents urine excretion, leading to kidney damage.
Acute Tubular Necrosis (ATN): Intrarenal
Direct injury to kidney tubules due to ischemia or toxins.
Gentamicin (Aminoglycoside antibiotic toxicity): Intrarenal
Causes nephrotoxicity, damaging renal tubules directly.
