Chapter 65 : Assessment of the Renal/Urinary System Questions
Question 1 of 5
A nurse assesses a client with renal insufficiency and a low red blood cell count. The client asks, Is my anemia related to the renal insufficiency? How should the nurse respond?
Correct Answer: C
Rationale: Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia and renal insufficiency are not manifestations of vitamin D deficiency. The kidneys do not play a role in the transportation of red blood cells or any other cells in the blood.
Question 2 of 5
A nurse contacts the health care provider after reviewing a clients laboratory results and noting a blood urea nitrogen (BUN) 10 mg/dL and a creatinine 1.0 mg/dL. For which action should the nurse recommend a prescription?
Correct Answer: A
Rationale: Normal BUN is 10"?20 mg/dL, and normal creatinine is 0.6"?1.2 mg/dL (males) or 0.5"?1.1 mg/dL (females). The values provided are within normal limits, so no immediate intervention like hemodialysis or urine culture is necessary. However, given the context, a 24-hour urine test could provide additional data on kidney function, making it the most appropriate recommendation.
Question 3 of 5
A nurse cares for a client with a urine specific gravity of 1.030. Which action should the nurse take?
Correct Answer: C
Rationale: Normal specific gravity for urine is 1.005"?1.030. A high specific gravity (1.030) can indicate dehydration, decreased kidney blood flow, or the presence of antidiuretic hormone. The most appropriate action is to increase the client's fluid intake to address potential dehydration. A urine culture is not indicated unless infection is suspected, and restricting fluids or administering ADH would worsen dehydration.
Question 4 of 5
A nurse reviews laboratory results for a client who was admitted for a myocardial infarction and cardiogenic shock. Which laboratory result indicates the client may have acute kidney injury?
Correct Answer: B
Rationale: Normal creatinine levels are 0.6"?1.2 mg/dL (males) or 0.5"?1.1 mg/dL (females). A creatinine level of 2.3 mg/dL is elevated, indicating possible acute kidney injury, especially in the context of cardiogenic shock, which can reduce renal perfusion. A BUN of 52 mg/dL is also elevated but less specific, as BUN can be affected by non-renal factors.
Question 5 of 5
Which condition would cause the release of antidiuretic hormone (ADH)?
Correct Answer: B
Rationale: ADH increases tubular permeability to water, leading to absorption of more water into the capillaries. ADH is triggered by a rising extracellular fluid osmolarity, as occurs in dehydration. Pneumonia, renal failure, and edema would not directly trigger the release of ADH.
