What is the best method to relieve intense itching under a cast?

1. Provide the client with a tongue blade to scratch.

2. Blow cool air into the cast using a blow dryer on a cool setting.

3. Request a prescription for an antihistamine.

4. Ask the provider to remove the cast immediately.

The correct answer is: Blow cool air into the cast using a blow dryer on a cool setting.

Using a blow dryer on a cool setting to blow cool air into the cast is an effective method for relieving intense itching under a cast. This approach allows the client to experience a cooling sensation, which can soothe the skin and alleviate discomfort without risking injury to the skin or causing damage to the cast. Cooling air can help reduce inflammation and provide temporary relief from the itching sensation. Offering a tongue blade for scratching poses a risk of injury to the skin, potentially leading to abrasions or infection. Requesting an antihistamine may help if the itching is due to an allergic reaction, but it doesn't address the immediate physical sensation of itching caused by the cast itself. Removing the cast is generally only warranted in cases where there are complications, such as circulatory issues or severe swelling, and is not a practical response to itching alone. Therefore, using cool air is a safe and immediate method to manage discomfort effectively.
