In caring for a client with GERD, which task would be appropriate to assign to the nursing assistant?
- A. Share successful strategies for weight reduction.
- B. Encourage the client to express concerns about lifestyle modification.
- C. Remind the client not to lie down for 2-3 hours after eating.
- D. Explain the rationale for small frequent meals.
Correct Answer: C
Rationale: The correct answer is C because reminding the client not to lie down after eating helps prevent acid reflux in GERD. Nursing assistants can provide this basic instruction to promote client safety. Choice A involves sharing strategies that require more in-depth knowledge, not within a nursing assistant's scope. Choice B involves addressing emotional concerns, typically handled by nurses. Choice D involves explaining the rationale, which requires more understanding of the condition, beyond a nursing assistant's role.

Where are most digestive enzymes secreted?
- A. stomach
- B. liver
- C. pancreas
- D. small intestine
Correct Answer: C
Rationale: The correct answer is C: pancreas. The pancreas secretes most digestive enzymes, including amylase, lipase, and proteases, into the small intestine to aid in the digestion of carbohydrates, fats, and proteins. It plays a crucial role in breaking down food components. The stomach (choice A) secretes gastric juices but not the majority of digestive enzymes. The liver (choice B) produces bile, which aids in fat digestion, but does not secrete digestive enzymes. The small intestine (choice D) is where most digestion and absorption occur, but it does not secrete the majority of digestive enzymes.
During the gastric phase of digestion
- A. There is neural stimulation only
- B. There is decreased contractility
- C. The bolus composition is detected by chemoreceptors
- D. It only takes minutes
Correct Answer: C
Rationale: Rationale:
1. Gastric phase starts when food enters the stomach.
2. Chemoreceptors detect bolus composition to initiate gastric secretions.
3. This detection triggers release of gastric juices for digestion.
4. Neural stimulation also occurs during gastric phase, but not exclusively.
5. Contractility increases during gastric phase for mixing and churning.
In summary, choice C is correct as chemoreceptors detect bolus composition during the gastric phase, while the other choices are incorrect because they do not accurately reflect the physiological processes during this phase.
A nurse enters the room of a client with cramping, bloating, and flatus, as well as diarrhea and/or constipation, with or without the presence of mucus. What condition do the client's symptoms represent?
- A. Peritonitis
- B. Irritable bowel syndrome
- C. Ulcerative colitis
- D. Appendicitis
Correct Answer: B
Rationale: The correct answer is B: Irritable bowel syndrome. The symptoms described align with the criteria for diagnosing IBS, such as cramping, bloating, and changes in bowel habits. Peritonitis (A) is characterized by severe abdominal pain, fever, and rigidity. Ulcerative colitis (C) presents with bloody diarrhea and abdominal pain. Appendicitis (D) typically causes localized right lower quadrant pain, nausea, and vomiting. Therefore, based on the given symptoms, IBS is the most likely diagnosis.
The nurse is caring for a patient who has been prescribed digoxin. Which statement by the patient indicates the need for further teaching about the medication?
- A. "I will report any changes in my pulse rate."
- B. "I should take my medication at the same time every day."
- C. "I can stop taking the medication if I feel dizzy."
- D. "I will monitor my weight weekly."
Correct Answer: C
Rationale: The correct answer is C. This statement indicates a need for further teaching because stopping digoxin abruptly can be dangerous. Digoxin should not be discontinued without consulting a healthcare provider. A: Monitoring pulse rate is important as digoxin can affect heart rate. B: Consistency in timing helps maintain consistent drug levels. D: Monitoring weight is crucial as digoxin can cause fluid retention. Therefore, choice C is incorrect as it suggests a potentially harmful action.
Which hormone stimulates the release of digestive enzymes from the pancreas?
- A. Insulin
- B. Glucagon
- C. Secretin
- D. Cholecystokinin (CCK)
Correct Answer: D
Rationale: The correct answer is D, Cholecystokinin (CCK). CCK is produced in the small intestine in response to the presence of fats and proteins. It stimulates the release of digestive enzymes from the pancreas to aid in digestion. Insulin (A) and Glucagon (B) are involved in regulating blood sugar levels, not digestive enzyme release. Secretin (C) primarily stimulates the release of bicarbonate from the pancreas to neutralize stomach acid, not digestive enzymes.
