Which intervention is appropriate when teaching clients about acupressure wrist bands?

Wearing acupressure wrist bands continuously is effective because these bands exert pressure on specific points on the wrist that are believed to help alleviate nausea. For the best results, they should be worn not just during episodes of nausea or vomiting, but consistently, as this allows for ongoing stimulation of the acupressure point. This continuous use can help in preventing nausea rather than just responding to it after it occurs.

Using these bands with medical supervision or as a sole treatment is not advisable, as they may be one part of a broader strategy to manage nausea, especially in conjunction with other treatments. Applying them only during episodes of vomiting misses the preventative aspect that continuous wearing provides, which is crucial for effectively managing symptoms.
