Which of the following nonpharmacologic interventions is effective for managing nausea and vomiting?

Acupuncture is recognized as an effective nonpharmacologic intervention for managing nausea and vomiting, particularly in certain contexts like postoperative nausea, motion sickness, and nausea related to chemotherapy. This traditional Chinese medicine technique involves the insertion of thin needles at specific points on the body, which is thought to help restore balance and promote the body’s natural healing processes. Research supports its efficacy in reducing the severity of nausea and the frequency of vomiting, making it a valuable complementary approach for individuals seeking relief without the use of medications.

Cognitive behavioral therapy, while beneficial for various psychological issues and anxiety management, does not directly address the physiological mechanisms behind nausea and vomiting. Increased fluid intake is important for overall hydration, especially if vomiting has occurred, but it does not specifically target the underlying causes of nausea. Prescription medications are pharmacologic interventions, which fall outside the scope of nonpharmacologic strategies that the question is focused on. Thus, acupuncture stands out as the most suitable choice in this context.
