Final answer:
CINV is a condition caused by chemotherapy that leads to nausea and vomiting. Medications like ondansetron can be used to prevent these symptoms. The answer is option 2.
Step-by-step explanation:
CINV stands for Chemotherapy Induced NV, which refers to the condition caused by chemotherapy that leads to nausea and vomiting. When a person undergoes chemotherapy treatment for cancer, the drugs can cause gastrointestinal disturbances, leading to feelings of nausea and the urge to vomit. These side effects are commonly referred to as chemotherapy-induced nausea and vomiting.
To manage CINV, medications such as ondansetron, also known as Zofran, can be used to prevent nausea and vomiting caused by chemotherapy. This medication works by blocking certain receptors in the brain, preventing the activation of the vomiting center and reducing the symptoms of CINV.
