Match each clinical presentation of a nephrologic or urologic emergency with its most appropriate targeted intervention.
- A 68-year-old male with end-stage renal disease misses two hemodialysis sessions. He presents with generalized weakness, a serum potassium level of 8.1 mEq/L, and an electrocardiogram demonstrating a sine-wave pattern.Intravenous administration of calcium gluconate
- A 35-year-old female treated with lithium for bipolar disorder presents with severe polyuria and a serum sodium of 152 mEq/L. Urine osmolality is 120 mOsm/kg and remains unchanged after the administration of exogenous desmopressin.Initiation of amiloride therapy
- A 50-year-old male is extricated from a collapsed building after 12 hours. He has swollen, tense lower extremities, tea-colored urine, and a serum creatine kinase of 45,000 U/L.Aggressive intravenous hydration with isotonic crystalloids
- A 70-year-old male with a known history of benign prostatic hyperplasia presents with severe suprapubic pain, agitation, and an inability to void for the past 18 hours. A tender mass is palpated in the lower abdomen.Immediate placement of a urethral catheter
Cevap
The missed dialysis patient requires calcium gluconate; the lithium toxicity patient requires amiloride; the crush injury patient requires aggressive hydration; and the prostatic hyperplasia patient requires a urethral catheter.
Each clinical scenario requires a specific, targeted intervention based on the underlying pathophysiology of the nephrologic or urologic emergency, ranging from membrane stabilization to mechanical obstruction relief.
Adım Adım Çözüm
Anahtar Kavram
Targeted management of nephrologic emergencies relies on identifying the primary pathophysiologic insult, such as membrane instability in hyperkalemia or tubular toxicity in rhabdomyolysis.
