A nurse is educating a group of patients with sickle cell disease (SCD) about complications.
Select all that apply:
Increased risk of infection.
Hypoxia and ischemia.
Blood clot formation.
Reduced risk of stroke.
Reduced adhesion of RBCs to the endothelium.
Correct Answer : A,B,C
Choice A rationale:
Patients with sickle cell disease (SCD) have an increased risk of infection due to the compromised immune function associated with the disease.
SCD can lead to functional asplenia, making individuals more susceptible to infections, particularly those caused by encapsulated bacteria.
Choice B rationale:
Hypoxia (lack of oxygen) and ischemia (reduced blood flow) are common complications of SCD.
The sickle-shaped red blood cells can obstruct blood vessels, leading to reduced oxygen delivery to tissues (hypoxia) and tissue damage due to impaired blood flow (ischemia)
Choice C rationale:
Blood clot formation is a known complication of SCD.
The altered shape of sickle cells can lead to the blockage of blood vessels, causing painful vaso-occlusive crises and increasing the risk of clot formation.
Choice D rationale:
This choice is incorrect.
Reduced risk of stroke is not associated with SCD.
In fact, individuals with SCD may have an increased risk of stroke due to the potential for vasculopathy and clot formation.
Choice E rationale:
Reduced adhesion of red blood cells (RBCs) to the endothelium is not a typical feature of SCD.
In fact, the adhesion of sickle cells to the endothelium is one of the pathophysiological mechanisms leading to vaso-occlusive events in SCD.

Correct Answer is D
Explanation
Choice A rationale:
"I've been experiencing fever and chills recently." Fever and chills can be associated with various illnesses and infections but are not specific clinical manifestations of sickle cell disease (SCD)
The primary concern in SCD is vaso-occlusion, anemia, and pain, which should be monitored closely.
Choice B rationale:
"I've noticed a yellowing of my skin and eyes." Yellowing of the skin and eyes (jaundice) can occur in SCD due to the breakdown of hemoglobin, but it is not directly related to the pain in the chest and joints described in the question.
Choice C rationale:
"I've been having trouble breathing and feeling weak." While respiratory symptoms and weakness can occur in SCD, they are not the primary clinical manifestations associated with pain in the chest and joints.
Painful erections and impotence are more directly related to SCD complications, such as priapism, which is a medical emergency and requires prompt attention.
Choice D rationale:
"I've had painful erections and impotence." Painful erections and impotence are potential complications of sickle cell disease (SCD), particularly due to priapism, a condition where blood becomes trapped in the penis.
This can lead to severe pain and, if not treated promptly, permanent erectile dysfunction.
Therefore, the nurse should be vigilant for these clinical manifestations to address them promptly.
Correct Answer is C
Explanation
Choice C rationale:
An elevated serum ferritin level in a patient with sickle cell disease (SCD) may signal iron overload.
Iron overload is a potential complication of chronic blood transfusions, which are often required in SCD to treat anemia and prevent complications.
Excessive iron accumulation can lead to organ damage, particularly in the liver, heart, and endocrine glands.
Monitoring and managing iron levels, including serum ferritin, are essential in SCD patients who receive regular transfusions.
Choice A rationale:
An elevated serum ferritin level does not indicate adequate iron stores.
In fact, it suggests the opposite, as it implies an excess of stored iron in the body.
Choice B rationale:
An elevated serum ferritin level is not indicative of iron deficiency anemia.
Iron deficiency anemia is characterized by low serum ferritin levels, as ferritin stores are depleted in this condition.
Choice D rationale:
An elevated serum ferritin level does not reflect normal hemoglobin levels.
Ferritin is a marker of iron storage and does not directly indicate the hemoglobin level, which measures the oxygen-carrying capacity of red blood cells.
