The practical nurse (PN) is performing a focused assessment of an adolescent girl's spine, the PN should ask the adolescent to assume which position?

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.

Rationale:

A. Request the client to reach for a spoon on the breakfast tray: Reaching for objects evaluates coordination and fine motor skills more than gross muscle strength. While it can provide some information, it is not a standardized or reliable method to assess upper extremity strength.

B. Tell the client to touch themself on the nose with a forefinger 5 times: This maneuver, known as the finger-to-nose test, assesses coordination, proprioception, and cerebellar function. It does not provide an accurate measure of muscle strength in the upper extremities.

C. Have the client use both hands to grip and squeeze the PN's hands: Handgrip strength testing is a direct, objective method to evaluate upper extremity muscle strength. By having the client squeeze the PN’s hands, the nurse can compare bilateral strength and identify weakness that may indicate neurologic impairment following a TIA.

D. Ask the client to extend both arms to the side and move in small to larger circles: This movement tests range of motion and coordination rather than strength. It is useful for assessing motor control but does not quantify or reveal muscle weakness effectively.
