URINARY
URINARY QUIZ 2
| Question | Answer |
|---|---|
| Microscopic structure (afferent arteriole) | Responsible for delivering blood to the glomerulus. |
| Urine formation | 1.Filtration 2.Reabsorption 3.Secretion |
| Filtration | Filtration of water and blood products occurs in the glomerulus of Bowman's capsule. |
| Reabsorption | Reabsorption of water, glucose, and necessary ions back into the blood occurs primarily in the proximal convoluted tubules, Henle's loop, and the distal convoluted tubules. |
| Secretion | Secretion of certain ions, nitrogenous waste products, and drugs occurs primarily in the distal convoluted tubule. This process is the reverse of reabsorption; the substances move from the blood to the filtrate. |
| Gross anatomic structure. | *Renal capsule *Renal cortex *Medulla *Papillae *Calyces *renal pelvis *ureter |
| Middle portion of kidney | Medulla |
| Functions of the kidney. | *Urine formation *Fluid and electrolyte control *Acid-base balance *Excretion of waste products * Blood pressure regulation *Red blood cell (RBC) production *Regulation of calcium-phosphate metabolism: |
| Acute renal failure (oliguric phase) | Oliguric phase : May last from several days to 4 weeks to several months. Some patients may experience the non-oliguric form, usually caused by nephrotoxic antibiotics, in which urinary output may exceed 2 L in 24 hours. |
| TURP (Transurethral resection of the prostate) | *Pt, may have continuous closed bladder irrigation or intermittent irrigation to prevent occlusion of the catheter with blood clots, which would cause bladder spasms. *Hematuria is expected *Monitor V/S & urine color q2hr for 24hr complications. |
| Hemodialysis | For patients with acute or irreversible renal failure and fluid and electrolyte imbalances. |
| Hemodialysis Nursing Interventions | *Dietary restrictions *Weigh before and after *V/S q 30-60 min. *Monitor s/s of fluid or electrolytes imbalances *Assess access site *Monitor for hemorrhage |
| Acute cystitis phenazopyridine (pyridium). | An over-the-counter urinary analgesic medication, may be encouraged to manage the discomfort. Its use should be limited to 2 days. It will turn the urine's color to a bright orange. |
| Serum creatinine | Dx. impaired kidney function. Female: 0.6 to 1. mg/dl Male: 0.7 to 1.3 mg/dl |
| Acid-base imbalance. | *Normal p.H. 7.35-7.45. *Normal P.a.C.O.2. 35-45. *Normal H.C.O.3. 21-28. |
| Spironolactone | Is a potassium sparing diuretic. |
