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 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.
Correct Answer is B
Explanation
A. Have the patient take a number and stay in the waiting area. Delaying care could lead to worsening of a potentially life-threatening bleeding episode. Hemophilia patients should be assessed promptly.
B. Place the patient in an examination room immediately and notify the physician of a potential bleeding crisis. Hemophilia patients are at risk of internal bleeding, which may not always be visible externally. Rapid assessment is essential to prevent complications from internal bleeding.
C. Send the patient for routine x-rays to locate the source of bleeding and place him in an examination room. X-rays may not immediately detect bleeding in soft tissues. The physician should evaluate the patient first.
D. Palpate the suspected area of bleeding for tenderness and edema. Palpating could worsen bleeding or cause pain, and the nurse should focus on ensuring the patient is seen promptly by the physician.
