A nurse is caring for a patient who has sepsis.

The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus.

How many mL/hr should the nurse set the IV pump to deliver?

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.

The correct answer is choicea. Increase daily caloric intake by 300 to 400 calories,b. Consume folic acid supplements daily, andd. Take daily iron and calcium supplements.

Choice A rationale:

Pregnant teenagers need to increase their daily caloric intake by 300 to 400 calories to support the growth and development of the fetus.

Choice B rationale:

Folic acid is crucial for preventing neural tube defects in the developing fetus.Daily supplementation is recommended.

Choice C rationale:

Pregnant teenagers need to increase their protein intake to support fetal growth and maternal health.Maintaining current protein intake is not sufficient.

Choice D rationale:

Iron and calcium are essential for the development of the fetus and the health of the mother.Daily supplementation helps prevent deficiencies.

Choice E rationale:

Limiting weight gain to no more than 15 pounds is not recommended.Healthy weight gain during pregnancy varies but is generally higher than 15 pounds to support fetal development.
