The painful or burning sensation in the chest usually associated with acid reflux in the esophagus is called
- A. a peptic ulcer.
- B. heart burn.
- C. angina.
- D. a duodenal ulcer.
Correct Answer: B
Rationale: The correct answer is B: heartburn. This is because heartburn is the common term for the painful or burning sensation in the chest caused by acid reflux in the esophagus. A peptic ulcer (A) and a duodenal ulcer (D) are sores in the stomach or small intestine, not specific to the chest area. Angina (C) is chest pain related to heart issues, not specifically caused by acid reflux. Therefore, B is the correct answer.

The patient with liver failure has had a liver transplant. What should the nurse teach the patient about care after the transplant?
- A. Alcohol intake is now okay.
- B. HBIG will be required to prevent rejection.
- C. Elevate the head 30 degrees to improve ventilation when sleeping.
- D. Monitor closely for infection because of the immunosuppressive medication.
Correct Answer: D
Rationale: The correct answer is D because patients who undergo liver transplant are put on immunosuppressive medication to prevent rejection. This medication weakens the immune system, making the patient more susceptible to infections. Monitoring closely for signs of infection is crucial to prevent complications.
Choice A is incorrect because alcohol intake is not recommended after a liver transplant as it can further damage the new liver. Choice B is incorrect because HBIG (Hepatitis B Immunoglobulin) is typically given to prevent hepatitis B recurrence, not rejection. Choice C is incorrect as elevating the head has no direct correlation with post-liver transplant care.
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.
Which of the following is true:
- A. Myenteric plexus controls GIT secretion.
- B. The normal concentration of bilirubin in the plasma is about 0.8 gm%.
- C. Submucosal plexus controls GIT motility.
- D. Pepsinogen activation needs Ca.
Correct Answer: B
Rationale: The correct answer is B because the normal concentration of bilirubin in the plasma is about 0.8 gm%, which is a commonly accepted fact in medicine. Bilirubin is a product of hemoglobin breakdown and is typically measured in the blood to assess liver function and detect certain medical conditions.
A, C, and D are incorrect:
A: Myenteric plexus controls GIT motility, not secretion.
C: Submucosal plexus controls GIT secretion, not motility.
D: Pepsinogen activation needs hydrochloric acid (HCl) in the stomach, not calcium.
Primary carcinoma is least common in:
- A. esophagus
- B. stomach
- C. small intestine
- D. colon
Correct Answer: C
Rationale: The correct answer is C: small intestine. Primary carcinoma is least common in the small intestine compared to the other choices. This is because the small intestine has a lower incidence of cancer compared to the esophagus, stomach, and colon. Factors contributing to this lower incidence include less exposure to carcinogens, a relatively smaller surface area, and less common inflammatory conditions that can lead to cancer development. Additionally, the small intestine has a more rapid turnover of cells, reducing the likelihood of cancerous mutations accumulating. Therefore, the small intestine is the least common site for primary carcinoma among the options provided.
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.
