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 C
Explanation
A. Hip: While “hip” can sometimes colloquially refer to the iliac crest, it is not commonly used to describe the specific site for aspiration outside of the iliac crest.
B. Cervical spine: The cervical spine is not a site used for bone marrow aspiration due to its inaccessibility and proximity to critical structures.
C. Sternum: The sternum is a common site for bone marrow aspiration in adults as it provides direct access to the marrow.
D. Humerus: The humerus is generally not used for bone marrow aspirations as it does not provide as accessible or large an area for aspiration.
Correct Answer is A
Explanation
A. Activity intolerance related to tissue hypoxia: Pernicious anemia leads to a decrease in the body’s ability to carry oxygen due to a lack of intrinsic factor and subsequent vitamin B12 deficiency, resulting in tissue hypoxia. This can cause fatigue and activity intolerance as the body struggles to meet its oxygen demands.
B. Ineffective airway clearance related to dyspnea: Dyspnea may occur, but ineffective airway clearance is not directly related to pernicious anemia, as this condition primarily affects oxygen transport, not the airway.
C. Risk for infection related to reduction in white blood cells (WBCs): Pernicious anemia primarily affects red blood cells due to vitamin B12 deficiency; it does not typically lead to a reduction in white blood cells.
D. Chronic pain related to bone marrow dysfunction: While bone marrow may be affected in some anemias, chronic pain is not a typical symptom of pernicious anemia, and bone marrow dysfunction is not usually present.
