A nurse is reviewing data for a client who has disseminated intravascular coagulation (DIC). Which of the following findings should the nurse expect?
Progressive increase in platelet production.
Excessive thrombosis and bleeding.
Immediate sodium and fluid retention.
Increased clotting factors.
The Correct Answer is B
A. Progressive increase in platelet production: In DIC, platelets are rapidly consumed, not increased, due to widespread clotting in the blood vessels.
B. Excessive thrombosis and bleeding: DIC is a complex condition where there is widespread activation of the clotting cascade, leading to excessive clotting and subsequent depletion of platelets and clotting factors, resulting in both thrombosis and bleeding.
C. Immediate sodium and fluid retention: Sodium and fluid retention are not specific findings in DIC; they may occur in cases of renal or heart failure but are unrelated to the clotting issues in DIC.
D. Increased clotting factors: In DIC, clotting factors are depleted as they are used up in widespread clotting, leading to bleeding when factors are exhausted.

Correct Answer is A
Explanation
A. The spleen is the primary site for platelet destruction. In ITP, the spleen often sequesters and destroys platelets, leading to low platelet levels. Removing the spleen reduces platelet destruction and can help increase platelet counts in affected patients.
B. The spleen is at risk for infection due to the critical loss of WBCs. While infection risk increases after splenectomy, this is not the rationale for the procedure. The spleen does play a role in immune function, but splenectomy is indicated for reducing platelet destruction, not infection prevention.
C. Your spleen is making too many platelets. The spleen does not produce platelets; rather, it filters and sometimes destroys them, particularly in ITP. This choice does not accurately reflect the pathophysiology of ITP.
D. The spleen causes an overabundance of immature platelets. The spleen does not cause an increase in immature platelets. In ITP, platelets are destroyed, not overproduced.
Correct Answer is D
Explanation
A. 2 hr: While some patients may tolerate faster infusion rates, the maximum safe time is 4 hours, and there is no requirement to complete it in 2 hours.
B. 8 hr: Blood cannot be left out for 8 hours due to the increased risk of bacterial growth and contamination.
C. 6 hr: Infusing blood over 6 hours exceeds the safe time limit and poses a risk of bacterial contamination.
D. 4 hr: To reduce the risk of bacterial contamination, a unit of packed RBCs must be transfused within 4 hours of starting the infusion. This time frame ensures that the blood remains safe for the patient while minimizing exposure to room temperature.
