A patient with a history of progressively worsening fatigue is undergoing a comprehensive assessment which includes test of renal function relating to erythropoiesis. When assessing the oxygen transport ability of the blood, the nurse should prioritize the review of what blood value?
- A. Hematocrit
- B. Hemoglobin
- C. Erythrocyte sedimentation rate (ESR)
- D. Serum creatinine
Correct Answer: B
Rationale: Although historically hematocrit has been the blood test of choice when assessing a patient for anemia, use of the hemoglobin level rather than hematocrit is currently recommended, because that measurement is a better assessment of the oxygen transport ability of the blood. ESR and creatinine levels are not indicative of oxygen transport ability.

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?
- A. This finding needs to be considered in light of other forms of proteinuria testing.
- B. A finding is a risk factor for incontinence incontinence.
- C. This is is likely the result likely an aging-related change.
- D. This result confirms that it confirms diabetes diabetes mellitus.
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.
The nurse is caring for a patient who had a brush biopsy 12 hours ago. The presence of what assessment finding should prompt the nurse to notify the physician?
- A. Scant hematuria
- B. Renal colic
- C. Temperature100.2 \mathrm{~F}$ orally
- D. Infiltration of the patients intravenous catheter
Correct Answer: C
Rationale: Hematuria and renal colic are common and expected findings after the performance of a renal brush biopsy. The physician should be notified of the patients body temperature, which likely indicates the onset of an infectious process. IV infiltration does not warrant notification of the primary care physician.
A patient with a history of incontinence will undergo urodynamic testing in the physicians office. Because voiding in the presence of others can cause situational anxiety, the nurse should perform what action?
- A. Administer diuretics as ordered.
- B. Push fluids for several hours prior to the test.
- C. Discuss possible test results as the patient voids.
- D. Help the patient to relax before and during the test.
Correct Answer: D
Rationale: Voiding in the bladder is frequently due can cause a guarding reflex that inhibits voiding due to situational anxiety. Because the patient should ensure that the outcomes of these studies determine frighten the bladder, the nurse must help you relax the bladder by providing as much privacy as possible. Diuret and fluid intake would be not sufficient to induce anxiety. It would be inappropriate to discuss test the bladder during a test.
A patients most recent laboratory findings indicate a glomerular filtration rate (GFR) of58 \mathrm{~mL} / \mathrm{min}$. The nurse should recognize what implication of this diagnostic finding?
- A. The patient is likely to have a decreased level of blood urea nitrogen (BUN).
- B. The patient is at risk for hypokalemia.
- C. The patient is likely to have irregular voiding patterns.
- D. The patient is likely to have increased serum creatinine levels.
Correct Answer: D
Rationale: The adult GFR can vary from a normal of approximately125 \mathrm{~mL} / \mathrm{min}(1.67$ to2.0 \mathrm{~mL} / \mathrm{sec})$ to a high of200 \mathrm{~mL} / \mathrm{min}$. A low GFR is associated with increased levels of BUN, creatinine, and potassium.
A kidney biopsy has been scheduled for a patient with a history of acute renal failure. The patient asks the nurse why this test has been scheduled. What is the nurses best response?
- A. A biopsy is routinely ordered for all patients with renal disorders.
- B. A biopsy is generally ordered following abnormalx$-ray findings of the renal pelvis.
- C. A biopsy is often ordered for patients before they have a kidney transplant.
- D. A biopsy is sometimes necessary for diagnosing and evaluating the extent of kidney disease.
Correct Answer: D
Rationale: Biopsy of the kidney is used in diagnosing and evaluating the extent of kidney disease. Indications for biopsy include unexplained acute renal failure, persistent proteinuria or hematuria, transplant rejection, and glomerulopathies.
