A nurse knows that the liver is a common site for metastasis from other primary cancers due to:

anatomic placement

portal hypertension

It’s blood supply

presence of tumor markers

Answer and Explanation

The Correct Answer is C

A. While the liver is centrally located and plays a significant role in filtering blood, its location alone does not directly explain why it's a common site for metastasis.
B. Portal hypertension refers to increased pressure within the portal vein system, usually due to liver disease, not metastasis.
C. The liver has a dual blood supply from the portal vein and the hepatic artery, which makes it a key organ for filtering blood coming from the digestive tract. This provides a route for cancer cells from the gastrointestinal tract and other organs to travel to the liver, making it a common site for metastasis.
D. Tumor markers are substances that may be found in higher amounts in the blood or tissues of people with cancer. However, they do not directly explain why the liver is a common site for metastasis.

Correct Answer is A

Explanation

A. The stoma will be edematous in appearance; this is an expected finding 24 hours after surgery. Mild to moderate edema is normal due to surgical manipulation and should gradually decrease over time.
B. Bowel sounds are often hypoactive or absent immediately post-op due to anesthesia and bowel manipulation, not hyperactive.
C. The colostomy appliance typically remains in place unless there's a leak or issue; routine replacement is not expected at 24 hours post-op.
D. A descending end colostomy involves only one stoma from the proximal end of the bowel; there is no distal stoma, so this option does not apply.

A. Jugular vein distention and +3 peripheral edema B. Increase in systolic blood pressure 10 mmHg above cents norm C. Complaints of epigastric pain after eating a large meal D. Complaints of dyspnea while completing ADLs

Correct Answer is A

Explanation

A. Jugular vein distention and +3 peripheral edema are signs of right-sided heart failure, which can result from worsening mitral stenosis. As the mitral valve becomes more narrowed, it leads to increased pressure in the left atrium and eventually backs up into the lungs and right side of the heart, causing fluid retention.
B. An increase in systolic blood pressure by 10 mmHg does not directly indicate worsening mitral stenosis. Blood pressure changes can occur for various reasons but are not as specific as signs of heart failure in this context.
C. Complaints of epigastric pain after eating a large meal are typically related to gastrointestinal issues rather than directly indicating worsening mitral stenosis.
D. Complaints of dyspnea while completing activities of daily living (ADLs) can be a sign of worsening mitral stenosis, but the additional signs of jugular vein distention and edema are more definitive indicators of worsening disease.
