The nurse is preparing a patient for a magnetic resonance cholangiopancreatography
A noninvasive technique, skeletal magnetic resonance imaging (MRI) produces clear and sensitive images of bone and soft tissue. The scan provides superior contrast of body tissues and allows imaging of multiple planes, including direct sagittal and coronal views in regions that can’t be easily visualized with X-rays or computed tomography scans. MRI eliminates any risks associated with exposure to X-ray beams and causes no
known harm to cells. There are two types of MRI. Closed MRI uses scanning equipment that resembles a tunnel like chamber. While open MRI uses more sophisticated equipment. During open MRI, the patient can comfortably see the surroundings from all views while the scan is in progress. This is ideal for patients who are claustrophobic or anxious, children, elderly, and the very obese. Purpose

Which enzyme is responsible for the release of vasoactive peptides?Angiotensin converting enzyme plays a key role in the hormonal regulation of blood pressure. It is responsible for the production of the vasoconstrictor hormonal peptide angiotensin II as well as the destruction of the vasodilator peptide bradykinin.
Which of the following factors may be associated with the development of cholelithiasis select all that apply?Cholelithiasis is the formation of gallstones. Risk factors include: being female, older age (over 40), Native American or Mexican American descent, pregnant, obesity, and family history.
Which scan will provide the most reliable diagnosis of acute pancreatitis?CT scans create pictures of your pancreas, gallbladder, and bile ducts. CT scans can show pancreatitis or pancreatic cancer.
Which medication would be administered after extracorporeal shock wave lithotripsy for treatment of cholelithiasis?In the treatment of gallstones with extracorporeal shock-wave lithotripsy, the bile acid ursodiol is administered to dissolve the gallstone fragments.
