What action should a person with sickle cell anemia take to prevent a sickling crisis?
Take prescribed pain medications
Avoid high altitudes
Eat a high-protein, high-fat diet
Avoid becoming dehydrated
The Correct Answer is D
Choice A reason: Taking pain medications manages symptoms of a sickling crisis but does not prevent it. Sickle cell crises occur due to hemoglobin S polymerization, triggered by hypoxia or dehydration, not directly prevented by analgesics, making this choice incorrect for prevention.
Choice B reason: Avoiding high altitudes reduces hypoxia, a trigger for sickling crises, as low oxygen levels promote hemoglobin S polymerization. While helpful, dehydration is a more significant and common trigger, making this choice less critical than avoiding dehydration.
Choice C reason: A high-protein, high-fat diet does not directly prevent sickling crises. Nutritional balance supports overall health, but sickle cell crises are triggered by dehydration, hypoxia, or infection, not dietary composition, making this choice incorrect for crisis prevention.
Choice D reason: Avoiding dehydration is critical in sickle cell anemia, as low fluid levels increase blood viscosity, promoting hemoglobin S polymerization and red cell sickling. This triggers vaso-occlusive crises, so maintaining hydration prevents these events, making this the correct choice.

Correct Answer is D
Explanation
Choice A reason: Warm skin indicates adequate blood flow and perfusion, often seen in normal or hyperemic states. Poor perfusion, due to reduced blood flow, typically causes cool skin as less warm blood reaches tissues, making this choice incorrect for poor perfusion.
Choice B reason: Pink nailbeds reflect good oxygenation and perfusion, as hemoglobin carries oxygen effectively to capillaries. Poor perfusion leads to pale or cyanotic nailbeds due to reduced blood flow or oxygen delivery, making this choice incorrect for indicating poor perfusion.
Choice C reason: Strong pulses indicate robust blood flow and adequate perfusion, as the heart pumps blood effectively to peripheral tissues. Poor perfusion is associated with weak or thready pulses due to low cardiac output, making this choice incorrect.
Choice D reason: Pale lips indicate poor perfusion, as reduced blood flow to peripheral tissues results in less hemoglobin delivering oxygen, causing pallor. This is a classic sign of hypoperfusion, often seen in shock or circulatory compromise, making this the correct choice.
Correct Answer is ["A","C","E"]
Explanation
Choice A reason: Stabilizing the wrist with an elastic wrap supports the injured ligaments, reducing movement and further damage. It promotes healing by maintaining alignment, making this a correct action for acute wrist sprain management.
Choice B reason: Applying a warm pack increases blood flow, which may worsen swelling in an acute sprain. Cold therapy is recommended to reduce inflammation and pain, making this choice incorrect for acute sprain management.
Choice C reason: Elevating the wrist above the heart reduces swelling by decreasing hydrostatic pressure, allowing fluid to drain from the injury site. This minimizes edema, making this a correct action for acute wrist sprain.
Choice D reason: Frequent massage may aggravate an acute sprain by increasing inflammation and pain. Rest and immobilization are preferred to promote healing, making this choice incorrect for acute wrist sprain management.
Choice E reason: Resting the wrist prevents further injury to damaged ligaments, allowing healing and reducing inflammation. Avoiding strain is critical in acute sprains, making this a correct action for wrist sprain recovery.
