Final answer:
The correct statement indicating successful understanding of the patient on how to use Nicorette is that the gum should be chewed slowly for about 30 minutes, allowing for consistent nicotine release and reduced side effects.
Step-by-step explanation:
When the nurse instructs the patient about how to use nicotine chewing gum [Nicorette], it is important that the patient understands the correct usage to maximize the benefits of nicotine replacement therapy. The correct statement that indicates successful teaching by the nurse would be: D."I should chew the gum slowly for about 30 minutes." This is because slowly chewing the gum allows for consistent release of nicotine and decreases the likelihood of side effects such as hiccups or gastrointestinal discomfort that can occur with more rapid chewing. The statement about avoiding eating or drinking before using the gum is also correct, as this can affect the absorption of nicotine. However, caution should be exercised during pregnancy with nicotine gum, and it is not considered safe without the advice of a healthcare provider.
