The nurse is caring for a patient who is receiving chemotherapy. Which of the following symptoms should be immediately reported to the healthcare provider?

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 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.

Correct Answer: B

Rationale: The correct answer is B: Liver. The liver is an accessory digestive organ as it produces bile, which aids in the digestion and absorption of fats in the small intestine. The other choices, A: Esophagus, C: Stomach, and D: Small intestine, are primary digestive organs involved directly in the process of digestion and absorption of nutrients. The esophagus is responsible for transporting food to the stomach, the stomach digests food with gastric juices, and the small intestine is where most of the digestion and absorption of nutrients occur. Therefore, the liver stands out as the correct answer as it supports the digestive process rather than directly participating in it.

Correct Answer: B

Rationale: The correct answer is B: Common bile duct. Gas is not typically present in the common bile duct in a normal healthy individual. The presence of gas in the stomach (A), small intestine (C), and transverse colon (D) is expected due to normal digestive processes. Gas in the common bile duct could indicate an abnormality such as a blockage or infection. Therefore, the absence of gas in the common bile duct on an X-ray of a normal healthy man is expected.
