Final answer:
The adverb phrase 'for now' indicates temporary relief from itching provided by the topical corticosteroid cream containing hydrocortisone, which reduces symptoms but does not treat the underlying cause of the rash.
Step-by-step explanation:
The adverb phrase 'for now' in the sentence 'This cream will help stop the itching for now' serves to indicate that the cream will provide temporary relief from itching. The clinical focus provided indicates that the cream is a topical corticosteroid containing hydrocortisone. Hydrocortisone works by reducing inflammation and suppressing the immune system's response, thereby alleviating the symptoms like itching and rashes known as pruritus. However, it does not treat the underlying cause of the rash but instead temporarily relieves the symptoms associated with it. Therefore, while the cream will help manage the symptoms for now, it is not a permanent cure and further investigation or treatment may be required to address the cause.
