A nurse is caring for an older adult client who has gastroenteritis. Which of the following actions should the nurse take?

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.

A) Offer the client a small meal if she is not nauseated:
While eating a small meal can help raise blood glucose levels, it is not the immediate priority in a severe hypoglycemia situation. The client might be unconscious or unable to swallow safely, making this action inappropriate as a first step.

B) Administer 1 mg of glucagon intramuscularly to the client:
Administering glucagon intramuscularly is the most crucial initial action. Glucagon rapidly increases blood glucose levels by stimulating glycogen breakdown in the liver. This is vital for quickly reversing severe hypoglycemia, especially if the client is unconscious or unable to ingest carbohydrates orally.

C) Contact the client's provider for further instructions:
Contacting the provider is essential, but it should occur after addressing the immediate hypoglycemic episode. Once the client's condition stabilizes, further guidance can be sought from the healthcare provider.

D) Transport the client to an emergency department for treatment:
Transporting the client to the emergency department is necessary if the hypoglycemia does not improve after administering glucagon or if the client remains unresponsive. However, it is not the first action; immediate glucagon administration takes precedence to stabilize the client's condition before considering transportation.
