A client has burns to the entire back, anterior and posterior surfaces of both legs, and the left arm.
Using the Rule of Nines, what percentage of total body surface area is burned?

Post-stroke rehabilitation necessitates the application of interdisciplinary care coordination principles. Knowledge of the specific scopes of practice for various therapists is required to identify which professional specializes in adapting the environment and teaching techniques for performing essential daily self-care tasks.

Choice A rationale

Physical therapists primarily focus on gross motor skills, such as gait training, balance, and lower extremity strength. While they assist with mobility, they do not specialize in the fine motor tasks or adaptive equipment used for daily self-care activities.

Choice B rationale

Case managers focus on the coordination of care, insurance authorization, and discharge planning. They facilitate the transition between care levels but do not provide the direct clinical therapy needed to improve a client's performance of daily tasks.

Choice C rationale

Occupational therapists specialize in helping clients regain independence with activities of daily living, such as dressing, bathing, and eating. They utilize task modification and adaptive devices to address the fine motor and cognitive deficits following a stroke.

Choice D rationale

Social workers address the psychosocial needs, financial resources, and emotional support systems of the client and family. While they assist with the broader aspects of recovery, they do not have the clinical training to improve physical self-care abilities..

Managing chronic kidney disease requires understanding the reciprocal relationship between calcium and phosphorus. Knowledge of renal osteodystrophy, vitamin D activation, and the role of the parathyroid hormone in mineral homeostasis is essential to identify the associated electrolyte shift.

Choice A rationale

Hypokalemia is not the primary association with hypocalcemia in kidney failure. Chronic kidney disease usually results in hyperkalemia, where potassium exceeds 5.0 mEq/L, because the failing kidneys cannot effectively excrete excess potassium ions into the urine.

Choice B rationale

Hypernatremia is an elevation of sodium above 145 mEq/L and is not directly linked to the calcium-phosphorus axis. While fluid balance is impaired in renal failure, sodium levels vary based on fluid volume status rather than hypocalcemia.

Choice C rationale

In kidney failure, phosphorus excretion decreases, leading to hyperphosphatemia. High serum phosphorus (above 4.5 mg/dL) binds with calcium, causing hypocalcemia (below 8.5 mg/dL). Additionally, decreased vitamin D activation in the kidneys further reduces calcium absorption from the gut.

Choice D rationale

Hyponatremia, or sodium below 135 mEq/L, often results from fluid overload in renal patients but is not the metabolic driver of low calcium. The hallmark mineral imbalance involves the inverse relationship specifically between serum phosphate and ionized calcium.
