The nurse is caring for a client who is scheduled for a blood sampling for a serum creatinine level. The client asks the nurse, "What is the purpose for this test?" Which of the following responses should the nurse give?
“This test will inform your provider if you are anemic.”
“This test will inform your provider if you have a thyroid disorder.”
“This test will inform your provider if you have an infection.”
“This test will inform your provider how your kidneys are functioning.”
The Correct Answer is D
A. “This test will inform your provider if you are anemic.” Hemoglobin and hematocrit levels are used to assess anemia, not creatinine.
B. “This test will inform your provider if you have a thyroid disorder.” TSH and T3/T4 levels assess thyroid function, not creatinine.
C. “This test will inform your provider if you have an infection.” Infection is usually assessed by WBC count, CRP, or cultures, not creatinine.
D. “This test will inform your provider how your kidneys are functioning.” Serum creatinine is a reliable indicator of renal function; it reflects the kidney’s ability to clear waste.

Correct Answer is ["A","C","E","F"]
Explanation
A. Regulate blood volume: Kidneys regulate fluid balance by adjusting urine output, influencing blood volume.
B. Excrete solid waste: Kidneys excrete liquid waste (urea, creatinine), not solid waste; the GI tract handles solids.
C. Role in regulation of blood pressure: Via the renin-angiotensin-aldosterone system (RAAS), kidneys influence vascular resistance and fluid volume.
D. Regulate body temperature: Thermoregulation is managed by the hypothalamus and skin, not the kidneys.
E. Regulate electrolyte content of blood: Kidneys regulate levels of sodium, potassium, calcium, and phosphate in the blood.
F. Role in RBC production: By releasing erythropoietin, kidneys stimulate RBC production in the bone marrow.
