A nurse is planning care for a patient who requires screening for rectal cancer. Which of the following tests should the nurse anticipate in the patient’s plan of care?
Colonoscopy
Endoscopic retrograde cholangiopancreatography (ERCP)
Upper GI series
Upper GI endoscopy .
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A rationale
The nurse should plan to refrigerate the urine during the collection time period. This is because the urine needs to be kept cool to prevent the breakdown of certain analytes that might be measured in the urine.
Choice B rationale
The nurse should not discard the client’s last void at the end of the collection time period. The last voided specimen should be included in the collection to ensure that the 24-hour collection is complete.
Choice C rationale
The nurse should not include toilet paper with the collected urine. Toilet paper could contaminate the urine sample and interfere with the accuracy of the test results.
Choice D rationale
The nurse should not save the first void at the start of the collection time period. The first voided specimen should be discarded, and the collection should start with the next void.
Correct Answer is ["75"]
Explanation
Step 1 is to divide the total volume of TPN by the total time in hours.
So, 1800 mL ÷ 24 hr = 75 mL/hr.
