A nurse is reviewing the trend of a client’s scores on the Glasgow Coma Scale (GCS). This provides what potential information to the nurse about the client’s status?

Reasoning:

Choice A reason: Hemoglobin A is the normal adult hemoglobin, comprising two alpha and two beta chains. In sickle cell anemia, a mutation in the beta-globin gene produces hemoglobin S, not hemoglobin A, which does not cause sickling or the vaso-occlusive crises characteristic of the disease.

Choice B reason: Hemoglobin S is the abnormal hemoglobin in sickle cell anemia, resulting from a point mutation in the beta-globin gene. This causes red blood cells to sickle under stress, leading to hemolysis and vaso-occlusion, resulting in pain, organ damage, and the clinical features of sickle cell crises.

Choice C reason: Hemoglobin M is a rare hemoglobin variant causing methemoglobinemia, not sickle cell anemia. It results from mutations affecting heme iron, leading to cyanosis, not the sickling and vaso-occlusion seen with hemoglobin S, making it irrelevant to the client’s condition.

Choice D reason: Hemoglobin F, or fetal hemoglobin, is present in newborns and persists in small amounts in adults. In sickle cell anemia, increased hemoglobin F can reduce sickling, but it is not the cause. Hemoglobin S drives the disease’s pathophysiology, not hemoglobin F.

Reasoning:

Choice A reason: Limiting bed rest to 4 weeks to prevent contractures and atrophy is not the primary principle. While prolonged immobility causes these issues, early mobilization post-stroke improves recovery and prevents complications like thromboembolism, making immediate mobilization the key focus rather than a time limit.

Choice B reason: Mobilizing as soon as physically able is critical post-ischemic stroke to enhance recovery. Early mobilization improves circulation, prevents thromboembolism, maintains muscle strength, and promotes neuroplasticity, reducing disability. This principle counters the family’s insistence on bed rest, which increases complication risks and hinders recovery.

Choice C reason: Waiting for the client to express a desire to mobilize delays recovery. Stroke patients may lack initiative due to neurological deficits or depression. Early mobilization, guided by physical ability, prevents complications like deep vein thrombosis and supports rehabilitation, making patient desire a poor criterion.

Choice D reason: Lack of mobility does not directly increase stroke recurrence risk, which is more tied to vascular risk factors like hypertension or diabetes. However, immobility increases complications like thromboembolism, which could indirectly contribute to stroke. Early mobilization is the priority to enhance overall recovery.
