The nurse is caring for a client who has completed a blood product transfusion for the treatment of thrombocytopenia. How would the nurse know that treatment has been successful?
White Blood Cell decrease
Platelets increase
Hemoglobin increase
PT and INR normalize
The Correct Answer is B
A. White Blood Cell decrease
Platelet transfusions do not affect WBC levels. WBCs may change in response to infection or inflammation, but this is not an indicator of successful platelet transfusion.
B. Platelets increase
The primary goal of platelet transfusion is to increase platelet count to reduce bleeding risk in thrombocytopenia.
C. Hemoglobin increase
Hemoglobin levels increase after red blood cell (RBC) transfusions, not platelet transfusions.
D. PT and INR normalize
PT/INR measures clotting function, which is affected by clotting factors, not platelets. Platelet transfusions do not directly correct prolonged PT/INR.

Correct Answer is C
Explanation
A. 63% TBSA
This value is too high based on the Rule of Nines calculation.
B. 45% TBSA
This overestimates the burn area.
C. 36% TBSA
Using the Rule of Nines, the TBSA is calculated as follows:
- Entire right arm (anterior + posterior): 9%
- Posterior trunk: 18%
- Posterior right leg: 9%
- Total TBSA = 9% + 18% + 9% = 36%
D. 27% TBSA
This underestimates the affected areas.
