A client with SCD is receiving oxygen therapy through a nasal cannula.
What is the purpose of oxygen therapy in the management of SCD?
To provide relief from severe pain.
To prevent tissue hypoxia.
To administer analgesics.
To induce relaxation.
The Correct Answer is B
Choice A rationale:
Oxygen therapy in the management of SCD is primarily aimed at preventing tissue hypoxia, not providing relief from severe pain.
SCD patients may experience pain due to tissue ischemia caused by the sickling of red blood cells, and oxygen can help prevent this by increasing the oxygen-carrying capacity of the blood.
Choice B rationale:
The primary purpose of oxygen therapy in the management of SCD is to prevent tissue hypoxia.
SCD patients are at risk of vaso-occlusive crises and tissue damage due to reduced oxygen delivery.
Supplemental oxygen helps maintain adequate tissue oxygenation and reduces the risk of complications.
Choice C rationale:
Oxygen therapy is not administered for the purpose of directly administering analgesics.
Analgesics are typically administered separately to manage pain in SCD patients.
Choice D rationale:
Oxygen therapy is not used to induce relaxation.
Its main goal is to improve oxygen saturation and prevent tissue hypoxia in SCD patients.

Correct Answer is A
Explanation
Choice A rationale:
Jaundice and gallstones are common complications of sickle cell disease (SCD) because of hemolysis, which is the destruction of abnormal red blood cells.
The breakdown of these cells releases bilirubin, leading to jaundice, and can also result in the formation of gallstones.
Choice B rationale:
This choice is incorrect.
Jaundice and gallstones in SCD are not caused by excessive iron intake in the diet.
Choice C rationale:
This choice is incorrect.
Allergic reactions to foods do not lead to jaundice and gallstones in SCD.
Choice D rationale:
This choice is incorrect.
Jaundice and gallstones in SCD do not result from an overproduction of normal red blood cells.
Correct Answer is D
Explanation
Choice A rationale:
"I've been having vision problems lately." Rationale: Vision problems are not directly associated with complications of sickle cell disease (SCD)
SCD primarily affects the blood and vascular system, leading to symptoms such as anemia, pain crises, and organ damage.
Vision problems may be caused by other underlying conditions, but they are not a typical manifestation of SCD complications.
Choice B rationale:
"I've had delayed growth in my child." Rationale: Delayed growth in a child could be associated with SCD, as it may be a result of chronic anemia and inadequate oxygen delivery to tissues.
However, it is not a direct clinical manifestation of complications.
Other more common complications, such as pain crises, acute chest syndrome, or organ damage, should be assessed first to determine the extent of the disease's impact on the patient's health.
Choice C rationale:
"I had a stroke a few years ago." Rationale: This statement is significant because stroke is a known complication of sickle cell disease.
SCD can lead to the occlusion of blood vessels, including those in the brain, resulting in stroke.
Therefore, the nurse should assess for any neurological deficits and gather more information about the stroke episode to assess its severity and potential impact on the patient's current condition.
Choice D rationale:
"I'm experiencing chest pain, fever, and cough." Rationale: Chest pain, fever, and cough are indicative of acute chest syndrome (ACS), which is a severe complication of SCD.
ACS can lead to respiratory distress and is considered a medical emergency.
The presence of these symptoms warrants immediate assessment and intervention, making choice D the correct answer.
