Final answer:
Ondansetron (Zofran) is used to prevent nausea and vomiting in clients undergoing chemotherapy, and the PN should evaluate its effectiveness by monitoring for a reduction in symptoms and potential side effects.
Step-by-step explanation:
The medication being evaluated is ondansetron, commonly known by its brand name Zofran, which is administered to a client prior to chemotherapy treatment. Ondansetron is an antiemetic used to prevent nausea and vomiting associated with chemotherapy, radiation therapy, or surgery. When evaluating the effectiveness of this medication, the Practical Nurse (PN) should monitor the client for a reduction in nausea and vomiting episodes. Additional considerations might include observing for potential side effects, such as headache, diarrhea, dizziness, or constipation, as well as ensuring the client understands the importance of taking the medication as prescribed.
Ondansetron is a controlled substance and is available in various forms, including intravenous injection as depicted alongside Zofran 4 mg in the provided image. PNs should ensure the medication is administered appropriately and safely. Proper storage and handling of controlled substances are also paramount. As mentioned, other medications like phenergan and special mouthwashes can be used in conjunction with ondansetron to further alleviate symptoms related to radiation therapy.
