A nurse is caring for a client who has a history of chemotherapy-induced nausea and vomiting. Which of the following medications should the nurse administer prior to chemotherapy?
Diphenhydramine
Ondansetron
Sertraline
Methylprednisolone
The Correct Answer is B
B. Ondansetron is a commonly used medication for preventing nausea and vomiting induced by chemotherapy. It belongs to a class of drugs called serotonin receptor antagonists, which work by blocking serotonin receptors in the brain and gastrointestinal tract, thereby reducing the sensation of nausea and the urge to vomit. Ondansetron is often administered prior to chemotherapy to help prevent these side effects.
A. Diphenhydramine works by blocking histamine receptors in the brain that trigger nausea and vomiting. However, it is not commonly used as a first-line antiemetic for chemotherapy-induced nausea and vomiting.
C. Sertraline is a selective serotonin reuptake inhibitor (SSRI) antidepressant and is not used specifically for preventing chemotherapy-induced nausea and vomiting.
D. Methylprednisolone is a corticosteroid medication that has anti-inflammatory and immunosuppressant effects.

Correct Answer is A
Explanation
A. Turning the client on their side helps prevent aspiration (inhaling fluid or vomit into the lungs) and promotes drainage of oral secretions, reducing the risk of airway obstruction during the seizure.
B. While assessing neurological status is important, it should be done after ensuring the client's safety during the seizure. This can be done after the seizure has stopped.
C. While obtaining vital signs is important for assessing the client's overall condition, it is not the immediate priority during an active seizure. Vital signs can be assessed once the seizure has stopped and the client's safety has been ensured.
D. Notifying the rapid response team may be necessary if the seizure persists beyond a certain duration (status epilepticus) or if there are complications. However, the first action should be to ensure the client's immediate safety by turning them onto their side to prevent aspiration.
Correct Answer is A
Explanation
A. Initiate IV fluid replacement is the highest priority intervention. HHS is characterized by severe dehydration due to osmotic diuresis resulting from hyperglycemia. IV fluid replacement is essential to correct dehydration and restore intravascular volume, which can help improve tissue perfusion and prevent further complications.
B. Monitoring urinary output is important in assessing renal function and response to fluid replacement therapy. However, it is not the highest priority intervention.
C. While insulin therapy is an essential part of managing hyperglycemia in HHS, it is not the highest priority intervention at the immediate onset of HHS.
D. Patient education about the manifestations and management of HHS is important for long-term management and prevention of recurrence. However, it is not the highest priority when the client is experiencing an acute episode of HHS.
