Which patient is at highest risk for having a gastric ulcer?
- A. 55-year-old female, smoker, with nausea and vomiting
- B. 45-year-old female admitted for illicit drug detoxification
- C. 37-year-old male, smoker, who fell while looking for a job
- D. 27-year old male who is being divorced and has back pain
Correct Answer: A
Rationale: The correct answer is A because a 55-year-old female who is a smoker and experiencing symptoms of nausea and vomiting has multiple risk factors for developing a gastric ulcer. Smoking and older age are established risk factors for gastric ulcers. Nausea and vomiting can be indicative of underlying gastrointestinal issues.
Choice B is less likely as illicit drug use typically does not directly increase the risk of gastric ulcers.
Choice C is less likely as the male falling while looking for a job does not directly relate to gastric ulcer development.
Choice D is less likely as divorce and back pain are not direct risk factors for gastric ulcers.

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.
GIT hormones with a major effect on the stomach include the following except:
- A. Gastrin
- B. Secretin
- C. GIP
- D. Neurotensin
Correct Answer: B
Rationale: Secretin is the correct answer because it is not a hormone that directly affects the stomach. Gastrin stimulates gastric acid secretion, GIP enhances insulin release, and neurotensin regulates gastric motility. Secretin primarily targets the pancreas and liver, stimulating the release of bicarbonate-rich pancreatic juice. This hormone does not have a direct major effect on the stomach like the other options. Therefore, Secretin is the exception among the listed GIT hormones affecting the stomach.
What contributes to increased protein-calorie needs?
- A. Surgery
- B. Vegan diet
- C. Lowered temperature
- D. Cultural or religious beliefs
Correct Answer: A
Rationale: The correct answer is A: Surgery. Surgery increases protein-calorie needs due to the body's increased demand for nutrients to support healing and recovery. The body requires more protein and calories to repair tissues and maintain immune function post-surgery.
Choice B: A vegan diet does not necessarily contribute to increased protein-calorie needs as it is possible to meet nutritional requirements with proper planning.
Choice C: Lowered temperature does not directly affect protein-calorie needs.
Choice D: Cultural or religious beliefs do not inherently increase protein-calorie needs, as dietary choices can still meet nutritional requirements.
The function of the gastrointestinal tract can be classified in several ways. Which of the following functions is most important for survival immediately after a meal?
- A. Absorption and retention of water and electrolytes
- B. Elimination of toxins
- C. Maintenance of barrier function
- D. Extraction of maximum value from nutrients
Correct Answer: A
Rationale: The correct answer is A: Absorption and retention of water and electrolytes. Immediately after a meal, the body needs to absorb water and electrolytes to maintain proper hydration and electrolyte balance, crucial for survival. This process helps in nutrient absorption and maintaining overall body function.
Reasons for why the other choices are incorrect:
B: Elimination of toxins - While important for overall health, elimination of toxins is not the most critical function immediately after a meal for survival.
C: Maintenance of barrier function - While important for protecting against harmful substances, it is not the most vital function immediately after a meal for survival.
D: Extraction of maximum value from nutrients - While important for optimal nutrition, it is not as crucial as absorption and retention of water and electrolytes for immediate survival post-meal.
A nurse is assessing a client who has an obstruction of the common bile duct resulting from chronic cholecystitis. Which of the following findings should the nurse expect?
- A. Fatty stools
- B. Straw-colored urine
- C. Tenderness in the left upper abdomen
- D. Ecchymosis of the extremities
Correct Answer: A
Rationale: The correct answer is A: Fatty stools. Common bile duct obstruction leads to inadequate bile flow into the intestines, resulting in malabsorption of fats. This causes fatty stools due to the presence of undigested fats. Straw-colored urine (B) is a normal finding. Tenderness in the left upper abdomen (C) is more indicative of splenic issues. Ecchymosis of the extremities (D) is unrelated to common bile duct obstruction.
