摘要

IT'S one thing to manufacture a tube; it's another to test it to verify its characteristics. Regardless of the raw material or the production method used to make the tube, pressure testing can be a necessary step in verifying the tube's quality. Whether the tubing is used for structural components or fluid transport systems, its strength and integrity are critical to knowing that the tube will hold up when it is put into service. Tube stock isn't the only form that should be tested. Tubular components that have additional features created by end forming, hydroforming, and other processes, or components added by welding or brazing, also should be tested. Improper or inadequate testing is a big step on the path to a product failure, which can lead to safety and environmental hazards.

7. Chemotherapy is one of the therapies for cancer patients that cause some side effects, one of them is nausea and vomiting. Nausea and vomiting are still felt by patients even though they take antiemetics. Nausea dan vomiting can cause fluid and electrolyte imbalance. The aim of this study was to analysis the effect of combination acupressure wristband and antiemetic among chemotherapy induced nausea vomiting (CINV) on breast cancer patients. This research used quasi experimental research method, with a pre-post test with the control group. The sampling techniques was consecutive sampling with 25 respondents both in intervention group and control group. In the intervention group had received an acupressure wristband. CINV measured on the second day until fourth day after chemotherapy. Nausea and vomiting score were measured twice a day by a telemonitoring methode by Rhodes Index Nausea, Vomiting and Retching (INVR) questionaire. Data were analyzed by paired t-test, independent t-test, Wilcoxon test and Mann Whitney. The result of this study showed that acupressure wristband significantly reduce the chemotherapy induced nausea and vomit (p value = 0.000). The use of acupressure wristband combined with antiemetic therapy can significantly decrease chemotherapy induced nausea and vomiting in breast cancer patients. Acupressure wristband recommended for consideration nursing intervention in treating breast cancer patients who experience nausea and vomiting. [O] . Endah Fatma 2018
