Following a cerebrovascular accident (CVA), a client's prescriptions include neurologic assessments every 8 hours, and bedrest. The agency assessment tool includes evaluation of the client's posture. Which action should the nurse implement?

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. Percussion: Percussion is used to assess underlying lung structures for air, fluid, or consolidation by evaluating sound changes. It is not the correct technique for assessing the physical shape or chest dimensions like the AP diameter.

B. Palpation: Palpation helps detect areas of tenderness, masses, or chest wall movement but does not accurately measure or evaluate the visual proportion of the AP to transverse chest diameter.

C. Auscultation: Auscultation is performed to assess lung sounds, such as crackles, wheezes, or diminished breath sounds. It does not provide information about the external shape or contour of the chest.

D. Observation: Observation is the correct method for assessing AP chest diameter. By visually inspecting the client from the side, the nurse can determine whether the chest is normally proportioned (approximately 1:2 AP to transverse ratio) or if there are abnormalities such as barrel chest, which can indicate chronic lung disease.
