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 D
Explanation
D. Obtaining an electrocardiogram (ECG) is the first action to take when managing a client with an electrical shock injury. Electrical shock injuries can cause cardiac dysrhythmias, including ventricular fibrillation or other life-threatening arrhythmias. Therefore, obtaining an ECG allows for prompt assessment of cardiac rhythm and identification of any dysrhythmias that may require immediate intervention.
A. While fluid resuscitation may be necessary in the management of electrical shock injuries to address hypovolemia and promote renal perfusion, titrating IV fluids to maintain a specific urine output is not the first action to take.
B. Pain management is important in the care of clients with electrical shock injuries, but it is not the first action to prioritize
C. Changing dressings over the entrance and exit wounds is important for wound care, but it is not the first action to take.
