What is an appropriate nursing intervention for a client experiencing mouth dryness and throat irritation after radioactive iodine therapy?

Recommending salt and soda water gargles is an appropriate nursing intervention for a client experiencing mouth dryness and throat irritation after radioactive iodine therapy. This approach provides a soothing effect to the mucous membranes of the mouth and throat. The salt helps to draw moisture into the tissues, promoting hydration and potentially alleviating discomfort, while the soda water can also act as a mild irritant that can help cleanse the mouth and stimulate saliva production.

In the context of nursing interventions, this strategy addresses common side effects of radioactive iodine therapy, which may include dryness and irritation due to altered salivary gland function. The combination of salt and soda is known for its benefits in reducing inflammation and in improving the mucosal environment, making it particularly effective in providing relief in such situations.
