A nurse is preparing to infuse a 250-mL unit of packed red blood cells (RBCs) over 2 hours.

The drop factor of the manual intravenous (IV) tubing is 15 drops/mL. How many drops per minute should the nurse adjust the flow rate to deliver?

Choice A rationale

Purulent drainage is thick and opaque. It can have a yellow, tan, green, or brown color and is a sign of infection.

Choice B rationale

Sanguineous drainage is bright red and indicates active bleeding3.

Choice C rationale

Serosanguineous drainage is typically pink-red and thin. It is made up of blood and serous fluid and is typically seen in a normal, non-infected wound3.

Choice D rationale

Serous drainage is clear and thin, like the fluid from a blister3.

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.
