A client is seen in the emergency department with severe pain related to a sickle cell crisis. What does the nurse understand is occurring with this client?
The client has a decreased tolerance of pain related to the chronic nature of the illness
Overhydration enlarges the red blood cells
Bone marrow decreases the erythrocyte production causing decrease in hypoxia
Vascular occlusion in small vessels decreasing blood and oxygen to the tissues
The Correct Answer is D
Reasoning:
Choice A reason: Decreased pain tolerance may occur in chronic conditions, but it is not the primary mechanism of pain in a sickle cell crisis. Pain results from vaso-occlusion by sickled red blood cells, causing tissue ischemia, not a psychological or tolerance issue, making this explanation incorrect.
Choice B reason: Overhydration does not enlarge red blood cells or cause sickle cell crises. Dehydration can trigger sickling by increasing blood viscosity, but overhydration dilutes plasma, potentially reducing sickling. Pain in crises stems from vaso-occlusion, not cell size changes due to fluid status.
Choice C reason: Bone marrow in sickle cell anemia increases, not decreases, erythrocyte production to compensate for chronic hemolysis. Hypoxia results from vaso-occlusion, not reduced production, as sickled cells block vessels, impairing oxygen delivery, making this an incorrect explanation for crisis-related pain.
Choice D reason: Vascular occlusion in small vessels by sickled red blood cells is the primary mechanism of sickle cell crisis pain. Sickled cells obstruct microvasculature, reducing blood flow and oxygen delivery, causing tissue ischemia and severe pain, accurately explaining the client’s symptoms in the emergency department.

Correct Answer is D
Explanation
Reasoning:
Choice A reason: Acknowledging the client’s relief does not educate them about the TIA’s significance. TIAs indicate transient cerebral ischemia, increasing stroke risk, but this response fails to address the need for risk modification, missing an opportunity to promote preventive measures critical for stroke prevention.
Choice B reason: Stating that TIA symptoms resolve within 24 hours is factually correct but does not emphasize the serious nature of TIAs as stroke precursors. Without addressing risk reduction, this response fails to educate the client on the need for lifestyle changes or medical intervention to prevent future events.
Choice C reason: Saying all TIA patients will develop a stroke is inaccurate, as not all progress to stroke. TIAs significantly increase stroke risk, but many can be prevented with proper management. This response is overly fatalistic and does not encourage proactive risk reduction strategies.
Choice D reason: Explaining that a TIA is a warning sign and discussing risk reduction educates the client about its significance as a transient cerebral ischemia event, increasing stroke risk. This response promotes lifestyle changes, medication adherence, and medical follow-up, empowering the client to prevent future strokes effectively.
Correct Answer is B
Explanation
Reasoning:
Choice A reason: Frequent urination may occur in Cushing’s syndrome due to hyperglycemia-induced osmotic diuresis, but it is not immediately life-threatening. It reflects chronic metabolic changes rather than an acute emergency, so it is less urgent than an irregular pulse, which could indicate a cardiovascular crisis.
Choice B reason: An irregular apical pulse is critical to report immediately in Cushing’s syndrome, as cortisol excess increases cardiovascular risk, including arrhythmias like atrial fibrillation. Irregular pulses may indicate acute cardiac instability, requiring urgent intervention to prevent complications like stroke or heart failure in this high-risk population.
Choice C reason: Dry mucous membranes may suggest dehydration but are not typical in Cushing’s syndrome, which causes fluid retention. Even if present, they are less urgent than an irregular pulse, as dehydration can be managed with fluids, whereas cardiac arrhythmias pose an immediate threat requiring prompt attention.
Choice D reason: Pitting edema in the legs is common in Cushing’s syndrome due to cortisol’s mineralocorticoid effects causing fluid retention. While important, it is a chronic issue manageable with diuretics and not as immediately life-threatening as an irregular pulse, which could indicate acute cardiac complications.
