While conducting a mental status examination of a newly admitted male client, the practical nurse (PN) notes that his head is lowered and he shows no emotion or expression when speaking. Based on these observations, which documentation should the PN include?

Rationale for correct choices:

• Shoulder: Abduction is the movement of the arm away from the midline of the body. The client’s inability to move the shoulder away from the body indicates a limitation in abduction. Assessing abduction is important after a stroke because hemiparesis or muscle weakness can limit the range of motion in this direction. This finding helps the nurse plan interventions such as passive range-of-motion exercises to maintain joint mobility.

• Wrist: Extension at the wrist refers to bending the wrist backward, toward the dorsal side of the forearm. The client’s ability to bend the wrist backward demonstrates preserved extension. Evaluating wrist extension is important for functional hand movements and self-care activities. Preserving wrist extension can help maintain grip and overall function during rehabilitation.

• Elbow: The elbow joint primarily performs flexion (bending) and extension (straightening). If the nurse is assessing the ability to straighten the arm, they are assessing Extension. A finding of "only 20 degrees" indicates a significant contracture or loss of ROM.

Rationale for incorrect choices

• Adduction : Adduction refers to movement toward the body’s midline. The client’s limitation is moving the shoulder away from the body, which is opposite of adduction. Similarly, the elbow and wrist assessments do not involve movement toward the midline. Selecting adduction would not correctly describe the observed range-of-motion limitations.

• Extension: Extension is the movement that increases the angle between two bones. The shoulder cannot extend away from the body in this scenario, and the elbow is only partially straightened, so extension is limited. The shoulder’s primary limitation is abduction.

• Abduction: Abduction is movement away from the midline, relevant primarily to shoulder and fingers. The wrist is assessed for flexion and extension, and the elbow is assessed for flexion/extension, not abduction. Selecting abduction for these joints would not match the observed movements and limits.

Rationale:

A. Normal should be within 3 seconds or 5 seconds in the older adult: While refill times can slow slightly with age, the standard clinical benchmark for a "normal" capillary refill is less than 2 seconds. In a fresh fracture and cast, a 4-second refill is a critical finding suggesting impaired peripheral perfusion

B. Use your thumbnail and press the nailbed proximal to the injury: Applying pressure with the thumbnail can cause unnecessary discomfort or injury, especially near a fractured limb. The standard technique is to press directly on the nailbed with a fingertip to avoid trauma while still effectively assessing perfusion.

C. Capillary refill is measured in seconds: Measuring the refill in seconds allows the nurse to quantify the perfusion and detect early signs of compromised circulation, which is critical for timely intervention in a client with a new cast and risk of neurovascular compromise.

D. Pressure placed on the nailbed should cause blanching: Blanching occurs when blood is temporarily displaced from the capillaries. Observing this response ensures that the capillary refill can be accurately timed, providing an objective assessment of blood flow distal to the fracture site.

E. Capillary refill is the time it takes to return to the client's normal color after releasing pressure: This step is the essence of the capillary refill test. It reflects the speed of arterial blood return, which is a vital indicator of adequate peripheral perfusion and early detection of circulatory compromise under a cast.
