A 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 of this test?" Which of the followingresponses should the nurse give?
"This test will inform your provider if you are anemic."
"This test will inform your provider if you have an infection."
"This test will inform your provider if you have a thyroid disorder."
"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." Serum creatinine is not used to assess anemia. Anemia is often evaluated through tests like hemoglobin and hematocrit.
b. "This test will inform your provider if you have an infection." Serum creatinine is not a direct indicator of infection. It is primarily used to assess kidney function.
c. "This test will inform your provider if you have a thyroid disorder." Serum creatinine is not
used to evaluate thyroid function. Thyroid function is typically assessed through thyroid function tests.
d. "This test will inform your provider how your kidneys are functioning." This is the correct
response. Serum creatinine is a waste product that is filtered by the kidneys, and elevated levels may indicate impaired renal function.

Correct Answer is C
Explanation
a. Serum chloride 99 mEq/L: Serum chloride within the reference range is not an adverse effect of spironolactone.
b. Serum calcium 10.5 mg/dL: Serum calcium within the reference range is not an adverse effect of spironolactone.
c. Serum potassium 5.2: Spironolactone is a potassium-sparing diuretic, and an elevated serum potassium level is an adverse effect that requires monitoring. The nurse should assess for
hyperkalemia.
d. Serum sodium 140 mEq/L: Serum sodium within the reference range is not an adverse effect of spironolactone.
Correct Answer is D
Explanation
a. Decrease the IV fluid infusion rate and limit oral fluid intake: The client's BUN and creatinine levels are not significantly elevated, and limiting fluid intake may exacerbate dehydration.
Decreasing the IV fluid rate may not be indicated without further assessment.
b. Collect a urine specimen for culture and sensitivity: While obtaining a urine specimen is
important, the priority in this case is to evaluate the urine output for amount and specific gravity to assess renal function and fluid balance.
c. Continue routine care because the results are within the expected reference range: The elevated BUN, along with nausea and vomiting, suggests the need for further assessment rather than
continuing routine care without adjustments.
d. Evaluate urine output for amount and urine for specific gravity: This is the correct action to assess renal function and fluid balance. Monitoring urine output and specific gravity will help determine if the client's kidneys are effectively concentrating urine and adequately excreting waste products.
