A nurse is caring for a client who is postoperative following a bowel surgery and has an NG tube connected to low intermittent suction. Which of the following assessment findings should indicate to the nurse that the NG tube might not be functioning properly?

A. Visitors are not completely prohibited, but their time should be limited and precautions followed, especially for children and pregnant individuals. Therefore, banning all visitors for 24 hours is unnecessary and overly restrictive.

B. Maintaining a distance of at least 3 feet from the radiation source helps reduce exposure, following the principle of distance in radiation safety. This is an appropriate and effective protective measure for the nurse.

C. Bed rest is typically required to prevent displacement of the sealed radiation device, but it is not specifically prescribed for a fixed duration like 72 hours. The duration depends on the treatment plan, so this statement is too rigid and not universally correct.

D. Dosimeter badges are worn by healthcare workers to measure occupational exposure, not by clients receiving radiation therapy. Therefore, this action is inappropriate for the client.

A. To best hear the closing of the aortic heart valve, the nurse should place the diaphragm of the stethoscope at the second intercostal space, right sternal border. This is also known as the aortic area.
B. This is the tricuspid region, and defects with the tricuspid valve will be best heard in this area.
C. This is the mitral region and murmurs due to defects in the mitral valve will be appreciated here
