A nurse is monitoring a client who is receiving a blood transfusion. The nurse identifies that the client has urticaria and is wheezing. Which of the following types of transfusion reactions should the nurse suspect?

A. The client should use a hair dryer on a warm setting to relieve itching inside the cast is incorrect. Using a hair dryer could cause skin burns or damage the cast. Additionally, the client should avoid introducing moisture into the cast, which could lead to skin irritation or infection.

B. The client's extremity should be elevated after the cast is applied is correct. Elevating the extremity helps reduce swelling and inflammation during the initial phase after cast application. It is important to elevate the limb above the level of the heart to promote venous return and reduce swelling.

C. The client can shower with the cast after 24 hr is incorrect. The plaster cast should not get wet. The nurse should instruct the client to keep the cast dry at all times. A plastic cover or cast protector should be used when showering to prevent moisture from seeping into the cast.

D. The client should keep the cast covered until it is dry is incorrect. It is true that the cast should be kept dry, but keeping it covered is not enough. The primary concern is preventing moisture and ensuring the plaster cast is allowed to air dry in a well-ventilated area without getting wet.

A. Place a pillow under the child's head: This is correct. The nurse should place a soft object, such as a pillow or folded blanket, under the child’s head to prevent head injury during a seizure. It is important to protect the patient from harm without interfering with the seizure.

B. Turn the child onto their back: This is not advisable during a seizure. The child should remain in a safe position, preferably on their side to help maintain the airway and prevent aspiration. Turning onto their back is not a first-line intervention.

C. Place a padded tongue blade in the child's mouth: This is incorrect. A padded tongue blade should never be inserted into the mouth during a seizure, as it can cause dental or oral injury, and may lead to aspiration or choking.

D. Restrain the child's upper extremities: Restraining the child is not recommended during a seizure. The child should not be physically restrained during the event, as this could cause injury or increase the risk of aspiration. The nurse should focus on providing safety and not interfering with the natural movements during a seizure.
