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 A
Explanation
a. Prothrombin time (PT): Warfarin affects the extrinsic pathway of the coagulation cascade, and PT is the primary diagnostic test used to monitor the therapeutic effect of warfarin. It measures
the time it takes for blood to clot.
b. Platelet count: Platelet count assesses the number of platelets in the blood and is not specifically used to monitor the effect of warfarin.
c. White blood cell count (WBC): WBC count assesses the number of white blood cells and is not specifically used to monitor the effect of warfarin.
d. Activated partial thromboplastin time (aPTT): While aPTT is a valuable test for monitoring the therapeutic effect of heparin, it is not the primary test for warfarin. Warfarin primarily affects the extrinsic pathway, and PT is more appropriate for monitoring its effects.
