In completing a physical assessment of a young adult, the clinic nurse observes muscular atrophy of the right thigh and calf. To gather additional data related to this finding, which action should the nurse take?

Rationale:
A. Assist the client to stand at the bedside long enough to observe posture: Assisting the client to stand would violate the bedrest order, which is in place to prevent complications such as increased intracranial pressure or falls following a CVA. Standing could pose unnecessary risks and is not appropriate when safer alternatives are available.

B. Observe the client's ability to sit upright or unassisted while in the bed: Evaluating posture can still be done safely within the constraints of bedrest by assessing how well the client can maintain an upright seated position. This allows the nurse to assess muscle tone, balance, and neurological function without compromising safety.

C. Document that posture could not be evaluated due to prescribed bedrest: Bedrest limits standing or walking, but it does not prevent all forms of posture evaluation. The nurse still has a responsibility to assess posture in ways that align with safety protocols and should not omit this part of the neurological assessment.

D. Ask the client to describe normal posture while walking and standing: Relying on the client's verbal report does not replace direct observation. Objective assessment is necessary for accurate neurological evaluation, especially in post-CVA clients where deficits in muscle control and balance may not be fully recognized by the client.

Rationale:
A. Hematocrit: Hematocrit measures the proportion of red blood cells in the blood and helps assess for anemia or dehydration, but it does not directly reflect short-term changes in nutritional status or protein stores.

B. Serum calcium: Serum calcium levels assess electrolyte balance and bone health but are not specific indicators of overall nutritional status. Calcium levels can be maintained even when nutritional intake is poor.

C. Hemoglobin: Hemoglobin evaluates oxygen-carrying capacity and can suggest anemia, which may indirectly reflect poor nutrition, but it is not as sensitive a marker for acute or current nutritional status as prealbumin.

D. Serum prealbumin: Serum prealbumin is a sensitive marker of recent nutritional intake and protein status, reflecting short-term changes in nutrition. It is the most important laboratory value to assess when evaluating a client for malnutrition, especially in the setting of appetite loss and generalized malaise.
