Which tissue layer provides for primary digestive motility?

Correct Answer: D

Rationale: The correct answer is D: Muscularis Mucosa. This layer is responsible for primary digestive motility due to its smooth muscle fibers that contract to move food along the digestive tract. The other choices do not directly contribute to motility. A: Mucosa is the innermost layer involved in absorption. B: Submucosa provides support and contains blood vessels. C: Mesentery is a connective tissue that supports and attaches organs, but does not directly regulate motility.

Correct Answer: C

Rationale: The correct answer is C: rugae. When the stomach is empty, it folds up into wrinkles called rugae. These folds allow the stomach to expand when food is consumed and contract when it is empty. Shincters (A) are muscular valves that control the flow of food in and out of the stomach, not the folds of the stomach itself. Bolus (B) refers to a small rounded mass of a substance, typically food that has been chewed and is ready to be swallowed, not the wrinkles of the stomach. Chyme (D) is the semi-fluid mass of partly digested food that is expelled by the stomach into the small intestine, not the folds of the stomach.

Correct Answer: B

Rationale: The correct answer is B: The patient uses witch hazel compresses to soothe irritation. Witch hazel has astringent and anti-inflammatory properties, which can help reduce inflammation and soothe irritated skin. By using witch hazel compresses, the patient is actively taking steps to alleviate discomfort and promote skin healing. A: The patient using incontinence briefs to contain loose stools does not address the issue of skin integrity maintenance and may lead to prolonged exposure of the skin to stool, exacerbating the problem. C: Asking for antidiarrheal medication after each stool does not directly address the need for skin integrity maintenance. While it may help reduce stool frequency, it does not specifically target skin healing. D: Cleaning the perianal area with soap after each stool can be harsh on the already excoriated skin and may further irritate it. Using soap can strip the skin of its natural oils and hinder the healing process.

Correct Answer: D

Rationale: The correct answer is D: Document stoma assessment findings. The rationale for this choice is that documentation is crucial in providing a clear and accurate record of the stoma's condition for ongoing monitoring and evaluation. By documenting the stoma assessment findings, the nurse can track any changes in color, edema, or drainage over time, which helps in identifying any potential issues or improvements. Choice A is incorrect because placing ice packs around the stoma can cause vasoconstriction and worsen the edema. Choice B is unnecessary at this point as the nurse can first assess and document the stoma before escalating to the surgeon if needed. Choice C is not the best action as monitoring every 30 minutes may be excessive and not practical, especially if the patient is stable.

Correct Answer: A

Rationale: The correct answer is A because parasympathetic impulses do not lead to the secretion of somatostatin. Somatostatin is released in response to low pH in the stomach to inhibit further acid secretion. Parasympathetic impulses stimulate the secretion of gastrin, promote histamine release, and inhibit somatostatin secretion. This is important for enhancing gastric acid secretion and promoting digestion. Therefore, choices B, C, and D are incorrect as they are effects of parasympathetic stomach impulses.
