A nurse is planning care for a client who requires screening for rectal cancer. Which of the following tests should the nurse anticipate in the client's plan of care?

Upper GI series

Colonoscopy

Endoscopic retrograde cholangiopancreatography (ERCP)

Upper GI endoscopy

Answer and Explanation

The Correct Answer is B

Choice A reason: An upper GI series is a series of X-rays used to examine the esophagus, stomach, and small intestine, not the rectum or colon.

Choice B reason: A colonoscopy is the most appropriate test for screening for rectal cancer as it allows for the

examination of the entire colon and rectum and can also facilitate the removal of polyps.

Choice C reason: ERCP is primarily used to diagnose and treat conditions in the liver, gallbladder, bile ducts, and pancreas, not the rectum.

Choice D reason: An upper GI endoscopy, or esophagogastroduodenoscopy (EGD), is used to examine the lining of the upper part of the gastrointestinal tract, which includes the esophagus, stomach, and duodenum, not the rectum.

Correct Answer is B

Explanation

Choice A reason: Magnesium is important for many processes in the body, including nerve transmission and the regulation of muscle contractions, but it is not primarily used for oxygen transport.

Choice B reason: Iron is a key component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. The normal range for iron in the blood is typically 50 to 170 micrograms per deciliter for men and 65 to 165 micrograms per deciliter for women.

Choice C reason: Potassium is crucial for heart function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function, but not directly for oxygen transport.

Choice D reason: Phosphorus helps form bones and teeth and is involved in the body's utilization of carbohydrates and fats, as well as the synthesis of protein for the growth, maintenance, and repair of cells and tissues, but it does not transport oxygen.

A. Dark-colored urine B. Leakage of urine C. Blood in urine D. Cloudy urine

Correct Answer is B

Explanation

Choice A reason: Dark-colored urine can be a sign of dehydration or the presence of certain substances in the urine, such as blood or bile, but it is not typically associated with urinary retention.

Choice B reason: Leakage of urine, or overflow incontinence, can occur in urinary retention when the bladder is overfilled and the pressure within the bladder exceeds urethral resistance. This can lead to involuntary release of urine.

Choice C reason: Blood in the urine, or hematuria, can indicate various conditions, including infections, stones, or tumors, but it is not a common finding specifically associated with urinary retention.

Choice D reason: Cloudy urine may suggest the presence of phosphates (a normal occurrence in alkaline urine), infection, or the presence of pus (pyuria). While it could be associated with a urinary tract infection that might lead to urinary retention, cloudy urine itself is not a direct indicator of urinary retention.
