Correct Answer is A

Explanation

A. Headache, dizziness, and fatigue

Ondansetron (Zofran) is commonly used to control nausea and vomiting associated with chemotherapy. While it is generally well-tolerated, some common side effects may include headache, dizziness, and fatigue.

B. Anorexia and hair loss

Anorexia (loss of appetite) and hair loss are not commonly associated with ondansetron. These symptoms may be side effects of chemotherapy itself, but they are not typically attributed to ondansetron.

C. Abdominal cramping and irritability

Abdominal cramping and irritability are not common side effects of ondansetron. These symptoms may be related to other factors, but they are not typically associated with this antiemetic medication.

D. Psychosis and middle ear disturbances

Psychosis and middle ear disturbances are not common side effects of ondansetron. These symptoms may be associated with other medications or conditions, but they are not typically attributed to ondansetron.
