Which of the following is NOT a common instruction for a CNA regarding patient care with casted limbs?

The correct choice is associated with specific caregiver duties that do not align with standard practices for managing a patient with casted limbs. Although assisting with patient transfers is generally a part of a CNA's responsibilities, the directive to do so frequently when a patient has a casted limb can increase the risk of complications, such as dislodging the cast or causing injury.

The other options focus on critical aspects of care for patients with casts. Avoiding moisture is important because moisture can weaken the cast material and lead to skin irritation or infections. Elevating the casted limb is encouraged to reduce swelling and promote circulation, which is vital for recovery. Monitoring for signs of circulation impairment is essential, as disruptions in blood flow can lead to serious complications, such as compartment syndrome. Each of these practices helps ensure patient safety and proper healing, making their inclusion in routine care essential for patients with casted limbs.
