Final answer:
Zofran, or ondansetron, is commonly prescribed to patients with persistent nausea and vomiting, particularly when associated with chemotherapy, radiation therapy, or surgery. It works by targeting certain receptors in the body to alleviate symptoms.
Step-by-step explanation:
For a patient presenting with persistent nausea and vomiting, a medication like Zofran (ondansetron) is commonly prescribed. Zofran is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, or surgery and can be administered via an intravenous injection. This medication targets specific receptors in the body to reduce the frequency and severity of nausea and vomiting.
In cases where nausea is due to pregnancy, commonly known as "morning sickness," it is often related to elevated levels of hormones such as estrogen and progesterone. While Zofran can be used in pregnancy, it is typically reserved for severe cases and always after a careful consideration of the benefits and potential risks. For general cases of nausea, antiemetic medications like Zofran and Phenergan are typically the first line of treatment regardless of the underlying cause.
