The nurse is caring for a patient in sickle cell crisis. What is the rationale for providing warm compresses and blankets for this patient?
Heat relaxes the muscles and distracts the patient from the pain.
Sickle cell crisis pain can be exacerbated with shivering.
Heat promotes proper formation of red blood cells (RBCs) and prevents sickling.
Heat increases circulation by preventing vasoconstriction.
The Correct Answer is D
A. Heat relaxes the muscles and distracts the patient from the pain. While warmth can provide comfort, the main goal is to improve circulation rather than distraction.
B. Sickle cell crisis pain can be exacerbated with shivering. Although shivering may be uncomfortable, it is not the primary reason for using heat during a sickle cell crisis.
C. Heat promotes proper formation of red blood cells (RBCs) and prevents sickling. Heat does not affect RBC formation or prevent sickling. The condition of sickling is due to genetic factors, not temperature.
D. Heat increases circulation by preventing vasoconstriction. In sickle cell crisis, warmth helps prevent vasoconstriction, which can reduce blood flow to areas already compromised by sickled cells. Preventing vasoconstriction may help alleviate pain and improve circulation.

Correct Answer is B
Explanation
A. "My son will have to grow a beard." Growing a beard is irrelevant to managing hemophilia and preventing bleeding.
B. "My son will have to avoid contact sports." Avoiding contact sports is essential for children with hemophilia to reduce the risk of trauma and bleeding episodes due to their clotting factor deficiency.
C. "My son will have to avoid fresh foods such as fruit in his diet." Fresh foods like fruits do not pose a bleeding risk for hemophilia; dietary restrictions are generally unnecessary in managing this condition.
D. "My son will always have to live near a major hospital."While proximity to a healthcare facility can be helpful in emergencies, this is not a requirement for managing hemophilia, nor does it directly prevent bleeding episodes.
Correct Answer is B
Explanation
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.
