The nurse would expect the least formed stool to be present in which portion of the digestive tract?

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.

Choice A The supine position (lying flat on the back) is not suitable for administering an enema as it does not facilitate proper flow and retention of the solution.

Choice B High Fowler's position (sitting upright at a 90degree angle) is not appropriate for enema administration, as it might cause discomfort and hinder proper administration.

Choice C Semi Fowler's position (sitting at a semiupright angle) is also not the best option for enema administration, as it may not allow the solution to flow effectively.

Choice D The Sims position, with the patient lying on the left side with the right knee flexed, allows the enema solution to flow downward by gravity and improves retention. It is the best position for enema administration.
