Chapter 65 : Assessment of the Renal/Urinary System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A nurse reviews a female clients laboratory results. Which results from the clients urinalysis should the nurse recognize as abnormal?
Correct Answer: B
Rationale: Ketone bodies are by-products of incomplete metabolism of fatty acids and are not normally present in urine. Their presence indicates abnormal metabolism, such as in diabetes or starvation. A pH between 4.6 and 8.0, specific gravity between 1.005 and 1.030, and clear yellow urine are normal findings.
Question 5 of 5
A nurse reviews the allergy list of a client who is scheduled for an intravenous urography. Which client allergy should alert the nurse to urgently contact the health care provider?
Correct Answer: A
Rationale: Seafood allergies are often associated with iodine sensitivity, which is critical because intravenous urography uses iodine-based contrast media. This allergy increases the risk of a severe reaction, requiring urgent consultation with the provider. Penicillin, bee sting, or red food dye allergies are less relevant to the procedure.
