A nurse educator explains to staff nurses that diarrhea can quickly become lifethreatening in elderly patients because

Choice A The shape of the abdomen is a physical assessment finding and not subjective

information provided by the patient. It involves the nurse's observation of the patient's abdomen during the examination.

Choice B Bowel sounds are also physical assessment findings that involve the nurse listening to the patient's abdomen using a stethoscope.

Choice C This is the correct answer. Abdominal cramping and discomfort are subjective symptoms reported by the patient and are relevant to the patient's bowel elimination status. Choice D Like the shape of the abdomen, the distention of the abdomen is a physical assessment finding and not subjective information provided by the patient.

The correct answer is choice b. Ascending colon.

Choice A rationale:

The sigmoid colon is the last part of the large intestine before the rectum. By this stage, the stool is usually well-formed as most water has been absorbed.

Choice B rationale:

The ascending colon is the first part of the large intestine where the stool is least formed. This is because it is the initial stage of the large intestine where water absorption begins, so the stool is still relatively liquid.

Choice C rationale:

The descending colon is further along the digestive tract, where more water has been absorbed, making the stool more formed compared to the ascending colon.

Choice D rationale:

The transverse colon is between the ascending and descending colons. While the stool here is more formed than in the ascending colon, it is less formed than in the descending and sigmoid colons.
