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","E","F"]
Explanation
A. The correct rate is 6 mL/hr
The correct calculation should be verified.
B. After contacting the prescriber, Nurse A should anticipate an order for IV Vitamin K
Protamine sulfate, not vitamin K, is the antidote for heparin.
C. The nurses will complete an event report due to the medication error
A medication error must be reported.
D. Nurse A will document about the event report in the patient’s EMR
Incident reports are internal documents and should not be documented in the EMR.
E. The patient has received a dose of heparin over the prescribed amount
Due to the increased concentration, the patient received more heparin than intended.
F. The patient has received 3200 units of heparin from 1700-1900.
This calculation confirms overdosing.
Correct Answer is A
Explanation
A. D-dimer, fibrinogen, and fibrin degradation products is correct because these tests reflect the excessive clotting and fibrinolysis seen in DIC: D-dimer: Elevated due to fibrin breakdown. Fibrinogen: Decreased due to excessive consumption. Fibrin degradation products (FDPs): Increased due to breakdown of fibrin clots.
B. Fibrin degradation products, lactic acid, and complete blood count is incorrect because lactic acid is more useful in sepsis evaluation, not DIC diagnosis.
C. Complete blood count, platelets, and prothrombin time is incorrect because while platelets may be low and PT may be prolonged, these tests alone are not specific for DIC.
D. Prothrombin time, form level, and d-dimer is incorrect because “form level” is not a relevant test, and PT alone is not sufficient for DIC diagnosis.
