Correct Answer is D

Explanation

Choice A reason:

Severe diarrhea can be a symptom of both Crohn's disease and ulcerative colitis and does not specifically indicate one over the other.

Choice B reason:

Involvement of the rectal mucosa is more indicative of ulcerative colitis rather than Crohn's disease, as Crohn's disease can affect any part of the digestive tract.

Choice C reason:

The presence or absence of blood in stool is not a definitive indicator of either Crohn's disease or ulcerative colitis, as both conditions can involve bleeding.

Choice D reason:

This statement is correct. A pattern of distinct exacerbations and remissions is more characteristic of Crohn's disease, whereas ulcerative colitis often presents with continuous, chronic symptoms.

Correct Answer is ["31.25"]

Explanation

To calculate the correct rate of flow for this patient, we need to use the formula: Rate (gtt/min) = Volume (mL) x Calibration (gtt/mL) / Time (min)
Plugging in the given values, we get: Rate (gtt/min) = 125 mL x 15 gtt/mL / 60 min
Simplifying, we get: Rate (gtt/min) = 31.25 gtt/min
Therefore, the correct rate of flow for this patient is 31.25 gtt/min
