A nurse is preparing to collect a specimen from a client for a guaiac test. The client asks what the test will detect in his stool. Which of the following responses should the nurse make?

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.

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.
