Ondansetron (Zofran) has been ordered for the patient undergoing cancer chemotherapy to control the severe nausea and vomiting. What side effects should the nurse observe for?

A. "I may experience urinary retention, dry mouth, and constipation."

This statement is accurate. Urinary retention, dry mouth, and constipation are common side effects of carbidopa-levodopa. The patient should be aware of these potential side effects and report them to the healthcare provider if they become problematic.

B. "I may feel dizzy at first, but this side effect will go away with time."

This statement is accurate. Dizziness is a common initial side effect of carbidopa-levodopa, and it often improves with continued use. The patient should be encouraged to report persistent dizziness to the healthcare provider.

C. "I should report nightmares and mental disturbances to my provider."

This statement is accurate. Nightmares and mental disturbances can be side effects of carbidopa-levodopa. The patient should report these symptoms to the healthcare provider for further evaluation and potential adjustments to the medication.

D. "I should take the drug with food to increase absorption."

This statement indicates a need for further teaching. Carbidopa-levodopa is best absorbed when taken on an empty stomach. Taking it with food, especially high-protein meals, can reduce its absorption. The patient should be instructed to take the medication at least 30 minutes before meals or one to two hours after meals for optimal effectiveness.

A. Depression:

CNS stimulants are generally not indicated for depression. In fact, they can exacerbate symptoms and are not considered a first-line treatment for depressive disorders.

B. Opiate overdose:

CNS stimulants are not indicated for treating opiate overdose. In cases of overdose, other medications like naloxone are commonly used to reverse the effects of opioids.

C. Poor appetite:

CNS stimulants may be used to increase alertness and decrease fatigue, but they are not typically prescribed to address poor appetite. Appetite stimulation is often managed through other approaches.

D. Narcolepsy:

This is the correct answer. CNS stimulants, such as modafinil or methylphenidate, are commonly prescribed to manage symptoms of narcolepsy. These medications help improve wakefulness and reduce excessive daytime sleepiness.
