Potter and Perry Chapter 46 - Urinary Elimination (Practice Questions) 2024

If obstructed, which component of the urination system would cause peristaltic waves? a. Kidney b. Ureters c. Bladder d. Urethra - Correct Answer ANS: B Ureters drain urine from the kidneys into the bladder; if they become obstructed, peristaltic waves attempt to push the obstruction into the bladder. The kidney, bladder, and urethra do not produce peristaltic waves. Obstruction of both bladder and urethra typically does not occur. When reviewing laboratory results, the nurse should immediately notify the health care provider about which finding? a. Glomerular filtration rate of 20 mL/min b. Urine output of 80 mL/hr c. pH of 6.4 d. Protein level of 2 mg/100 mL - Correct Answer ANS: A Normal glomerular filtration rate should be around 125 mL/min; a severe decrease in renal perfusion could indicate a life-threatening problem such as shock or dehydration. Normal urine output is 1000 to 2000 mL/day; an output of 30 mL/hr or less for 2 or more hours would be cause for concern. The normal pH of urine is between 4.6 and 8.0. Protein up to 8 mg/100 mL is acceptable; however, values in excess of this could indicate renal disease. A patient is experiencing oliguria. Which action should the nurse perform first? a. Increase the patient's intravenous fluid rate. b. Encourage the patient to drink caffeinated beverages. c. Assess for bladder distention. d. Request an order for diuretics. - Correct Answer ANS: C The nurse first should gather all assessment data to determine the potential cause of oliguria. It could be that the patient does not have adequate intake, or it could be that the bladder sphincter is not functioning and the patient is retaining water. Increasing fluids is effective if the patient does not have adequate intake, or if dehydration occurs. Caffeine can work as a
