A nurse is completing dietary teaching with a client who has the inflammatory bowel disorder ulcerative colitis. Which of the following statements by the client indicates an understanding of the teaching?

A) Protective environment
This type of isolation is used for clients with weakened immune systems to protect them from infections. It is not necessary for pertussis, which requires droplet precautions to prevent spread.

B) Airborne precautions
These are used for diseases that are spread through tiny droplets that remain in the air, such as tuberculosis. Pertussis spreads through larger respiratory droplets, not lingering in the air, so airborne precautions are not needed.

C) Contact precautions
These are used for infections spread by direct touch or contact with surfaces. Pertussis primarily spreads through respiratory droplets rather than direct contact, making contact precautions unnecessary.

D) Droplet precautions
Droplet precautions are appropriate for pertussis, as it spreads via respiratory droplets when an infected person coughs or sneezes. This involves wearing masks and maintaining distance to prevent transmission.

A) Position the cast on a plastic-covered pillow:
Positioning the cast on a plastic-covered pillow is not recommended because the plastic can trap moisture and heat, potentially affecting the cast's integrity as it dries. Instead, a soft, absorbent material should be used to support the cast.

B) Perform neurovascular checks every 2 hr:
Frequent neurovascular checks are essential to monitor for complications such as compartment syndrome, nerve damage, or impaired circulation. This action helps ensure that any changes in sensation, movement, or circulation are identified and addressed promptly.

C) Instruct the client to avoid moving the fingers on the left hand:
Encouraging the client to move their fingers is important to prevent stiffness and swelling and to promote circulation. Instructing the client to avoid moving their fingers is not appropriate and could lead to complications.

D) Touch the cast with the palms of the hands when moving the client:
Handling a wet plaster cast with the palms of the hands is correct to prevent indentations and pressure points that could cause skin irritation or pressure sores. However, this action is not as critical as performing frequent neurovascular checks to ensure the client's safety and monitor for complications.
