The nurse is assessing a patient's bowel sounds. After auscultating each quadrant for 30 seconds, the nurse fails to hear any sounds. How should the nurse document this finding?

Correct Answer: B

Rationale: The correct answer is B: Hypoactive bowel sounds. This is because the nurse did not hear any bowel sounds after auscultating each quadrant for an adequate amount of time. Hypoactive bowel sounds indicate decreased or slowed bowel motility, which could be due to various factors such as postoperative ileus or constipation. The other choices are incorrect because Absent bowel sounds (choice A) would mean no sounds at all, Active bowel sounds (choice C) would indicate normal bowel motility, and Hyperactive bowel sounds (choice D) would indicate increased bowel motility, all of which are not reflective of the nurse's assessment findings.

Correct Answer: C

Rationale: The correct answer is C: Blood in the stool. This symptom may indicate gastrointestinal bleeding, a serious side effect of chemotherapy that requires prompt medical attention. Reporting it immediately can help prevent further complications. A: Diarrhea is a common side effect of chemotherapy but is not typically considered an emergency. B: Nausea is another common side effect that can usually be managed with medication and does not require immediate reporting. D: Fatigue is a common symptom of chemotherapy and is typically managed with rest and supportive care, not requiring immediate reporting. In summary, blood in the stool is the most concerning symptom that requires immediate attention compared to the other choices, which are common side effects of chemotherapy.

Correct Answer: C

Rationale: The correct answer is C: large intestine. The large intestine is responsible for absorbing the majority of water in the digestive system. This occurs in the colon, where water is reabsorbed from the indigestible food residue, turning it into solid waste. The stomach (A) primarily breaks down food, the small intestine (B) absorbs nutrients, and the rectum (D) stores feces before elimination. Therefore, the large intestine is the correct choice for water absorption in the digestive process.

Correct Answer: C

Rationale: The term 'chyme' refers to food mixed with digestive juices in the stomach. This mixture is the result of mechanical and chemical digestion processes. Choice A, undigested food, is incorrect as chyme is a product of digestion. Choice B, partially digested food, is not precise enough as chyme specifically refers to the semi-fluid mass in the stomach. Choice D, absorbed nutrients, is incorrect as chyme is not yet at the stage where nutrients are absorbed. Thus, choice C is correct as it accurately describes the composition of chyme in the digestive system.

Correct Answer: A

Rationale: Cholecystokinin (CCK) is released after a meal to stimulate the release of bile from the gallbladder into the small intestine to aid in digestion and absorption of fats. This process is crucial for emulsifying fats and enhancing their digestion. Choice A is correct because it directly aligns with the primary function of CCK. Choices B, C, and D are incorrect because CCK does not play a role in stimulating gastric acid secretion, insulin release, or absorption of nutrients. These functions are typically controlled by other hormones such as gastrin, insulin, and various enzymes in the digestive system.
