Final answer:
The statement by the client that shows the acupressure bands are effective is 'I have not vomited as much recently.' This aligns with the intended purpose of the bands, which is to reduce nausea and vomiting, common symptoms of morning sickness in the first trimester of pregnancy.
Step-by-step explanation:
A client who is in the first trimester of pregnancy is experiencing physical changes and may have symptoms such as nausea and vomiting, often referred to as morning sickness. Use of acupressure bands on the wrists is a common non-pharmacological method to help alleviate these symptoms. In this scenario, the statement by the client that indicates the therapy is having the desired effect is D) I have not vomited as much recently.
During the first trimester, many pregnant individuals go through a period where nausea is enhanced, and this discomfort is particularly common in the morning, but can occur at any time of the day. Acupressure bands are designed to apply pressure to certain points on the wrist that are associated with relieving nausea. Therefore, if the client reports a reduction in vomiting, it can be inferred that the bands are effective in mitigating one of the discomforts that are prevalent during early pregnancy.
Other statements such as A) I have not had any food cravings, B) The spotting I was having has stopped, and C) I don't feel depressed anymore, do not directly relate to the effects acupressure bands would typically have on the symptoms of morning sickness in pregnancy.
