A nurse is providing care for a patient who has deep vein thrombosis.

The patient is prescribed heparin, which is to be administered via continuous IV infusion at a rate of 1,200 units/hr. If the available heparin is 25,000 units in 500 mL DSW, how many mL/hr should the IV pump be set to deliver?

(Round your answer to the nearest tenth or whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale

The stoma for a sigmoid colostomy is typically located in the lower left abdomen. This is because the sigmoid colon is a part of the large intestine that is located in the lower left quadrant of the abdomen.

Choice B rationale

A stoma should appear pink or red and moist. A purple stoma could indicate a lack of blood supply, which is a medical emergency.

Choice C rationale

A sigmoid colostomy will produce formed stool because the sigmoid colon is the last part of the colon, where water is absorbed and stool is formed.

Choice D rationale

The end of the stoma (the part that sticks out from the abdomen) should not be painful after the procedure. If a patient experiences pain, it could indicate a complication such as a blockage or infection.

Choice A rationale

A colonoscopy is the standard investigation for colorectal cancer. It allows for the visualization of the entire colon and rectum, and can also allow for the removal of polyps and the taking of biopsies if needed.

Choice B rationale

Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure used to diagnose diseases of the gallbladder, biliary system, pancreas, and liver, not rectal cancer.

Choice C rationale

An upper GI series, which involves X-rays of the esophagus, stomach, and small intestine, would not be used for screening for rectal cancer.

Choice D rationale

An upper GI endoscopy, which involves the use of a flexible endoscope to visualize the esophagus, stomach, and duodenum, would not be used for screening for rectal cancer.
