Chapter 53 : Assessment of Kidney and Urinary Function Questions
Question 1 of 5
Dipstick testing of an older adult patient's urine indicates the presence of protein in urine protein. Presence indicates which of the following statements is true?
Correct Answer: A
Rationale: The test, which detects 30 to1000,000 / \mathrm{dL}$ of protein, should only used as a screening test, as screening affects urine concentration, affects pH concentration, hematuria, and radiocontast affect materials results results. Protein is not a diagnostic of diabetes, it is not age-related, nor is a risk factor for urinary incontinence.
Question 2 of 5
What should the nurse perform when caring for a who patient undergoing a diagnostic of the renal-urologic system?
Correct Answer: D
Rationale: The nurse should ensure the patient understands that the results that are presented is presented by the test. Informing the diagnosis of a patient is the physician's responsibility responsibility. Withholding fluids or fluids is not normally required after test.
Question 3 of 5
The care team is considering the use of dialysis in a patient whose renal function is progressively declining. Renal replacement therapy is indicated in which of the following situations?
Correct Answer: D
Rationale: When the total number of functioning nephrons is less than20 %, renal replacement therapy needs to be considered. Dialysis is an example of a renal replacement therapy. Prior to the loss of about80 % of the nephron functioning ability, the patient may have mild symptoms of compromised renal function, but symptom management is often obtained through dietary modifications and drug therapy. The listed creatinine and BUN levels are within reference ranges.
Question 4 of 5
A nurse knows that specific areas in the ureters have a propensity for obstruction. Prompt management of renal calculi is most important when the stone is located where?
Correct Answer: A
Rationale: The three narrowed areas of each ureter are the ureteropelvic junction, the ureteral segment near the sacroiliac junction, and the ureterovescial junction. These three areas of the ureters have a propensity for obstruction by renal calculi or stricture. Obstruction of the ureteropelvic junction is most serious because of its close proximity to the kidney and the risk of associated kidney dysfunction. The urethra is not part of the ureter.
Question 5 of 5
A nurse is caring for a patient with impaired renal function. A creatinine clearance measurement has been ordered. The nurse should facilitate collection of what samples?
Correct Answer: B
Rationale:
To calculate creatinine clearance, a 24-hour urine specimen is collected. Midway through the collection, the serum creatinine level is measured.
