Which of the following will have the greatest implication on a client scheduled for a percutaneous liver biopsy?
- A. History of coagulation studies
- B. Allergy to iodine
- C. Family history of GI disorders
- D. Presence of radioactive material in the work environment
Correct Answer: A
Rationale: The correct answer is A: History of coagulation studies. This is because coagulation studies assess the client's ability to form blood clots, which is crucial for a percutaneous liver biopsy to prevent excessive bleeding. It helps determine the risk of bleeding complications during the procedure.
Choice B, Allergy to iodine, is incorrect because an allergy to iodine is more relevant in procedures involving contrast media, not typically in percutaneous liver biopsies.
Choice C, Family history of GI disorders, is incorrect as it does not directly impact the client's safety or outcome during a percutaneous liver biopsy.
Choice D, Presence of radioactive material in the work environment, is also incorrect as it is not directly related to the procedure or its implications on the client's safety during a percutaneous liver biopsy.

Which of the following structures would be considered retroperitoneal?
- A. pancreas
- B. stomach
- C. jejunum
- D. spleen
Correct Answer: A
Rationale: The correct answer is A: pancreas. The pancreas is considered retroperitoneal because it lies behind the peritoneum, specifically in front of the vertebral column. This positioning makes it retroperitoneal, unlike the stomach, jejunum, and spleen, which are intraperitoneal organs located within the peritoneal cavity. The retroperitoneal location of the pancreas helps protect it and provides structural support. It also allows for easier access during surgical procedures, as it is not surrounded by peritoneum on all sides like intraperitoneal organs.
In report, the nurse learns that the patient has a transverse colostomy. What should the nurse expect when providing care for this patient?
- A. Semiliquid stools with increased fluid requirements
- B. Liquid stools in a pouch and increased fluid requirements
- C. Formed stools with a pouch, needing irrigation, but no fluid needs
- D. Semiformed stools in a pouch with the need to monitor fluid balance
Correct Answer: A
Rationale: The correct answer is A: Semiliquid stools with increased fluid requirements. A transverse colostomy is located in the upper part of the colon, where stool consistency is more liquid. This type of colostomy typically produces semiliquid stools due to the shorter transit time in the colon, leading to increased fluid requirements to prevent dehydration.
Summary of other choices:
B: Liquid stools in a pouch and increased fluid requirements - Incorrect because transverse colostomies produce semiliquid stools, not entirely liquid.
C: Formed stools with a pouch, needing irrigation, but no fluid needs - Incorrect as transverse colostomies do not produce formed stools, and fluid intake is necessary.
D: Semiformed stools in a pouch with the need to monitor fluid balance - Incorrect because transverse colostomies produce semiliquid stools, not semiformed, and increased fluid intake is needed.
In discussing long-term management with the patient with alcoholic cirrhosis, what should the nurse advise the patient?
- A. A daily exercise regimen is important to increase the blood flow through the liver.
- B. Cirrhosis can be reversed if the patient follows a regimen of proper rest and nutrition.
- C. Abstinence from alcohol is the most important factor in improvement of the patient's condition.
- D. The only over-the-counter analgesic that should be used for minor aches and pains is acetaminophen.
Correct Answer: C
Rationale: The correct answer is C: Abstinence from alcohol is the most important factor in improvement of the patient's condition. This is because alcohol is the primary cause of alcoholic cirrhosis, and continued consumption can worsen liver damage. Abstinence allows the liver to heal and potentially improve function.
Explanation of why the other choices are incorrect:
A: A daily exercise regimen is important for overall health but may not specifically increase blood flow through the liver in alcoholic cirrhosis.
B: Cirrhosis is irreversible, although proper rest and nutrition can help manage symptoms and prevent further damage.
D: Acetaminophen can be harmful to the liver in high doses and should be used cautiously in patients with cirrhosis.
The pancreas produces all of the following except which one?
- A. amylase
- B. lipase
- C. insulin
- D. bile
Correct Answer: D
Rationale: The correct answer is D: bile. The pancreas produces digestive enzymes such as amylase and lipase to break down carbohydrates and fats. It also produces insulin to regulate blood sugar levels. Bile, however, is produced by the liver and stored in the gallbladder, not by the pancreas. Therefore, the pancreas does not produce bile. This makes option D the correct answer.
In human, the cardiac sphincter surrounds the cardiac orifice in the digestive tract. The failure of this sphincter's normal function will result in
- A. regurgation of the food into the oesophagus
- B. loss of control of defecation
- C. movement of the bolus into the trachea rather than the oesophagus
- D. rapid emptying from the stomach to the small intestine
Correct Answer: A
Rationale: The correct answer is A: regurgitation of the food into the oesophagus. The cardiac sphincter is located at the junction between the esophagus and the stomach. Its main function is to prevent the backflow of stomach contents into the esophagus. If the cardiac sphincter fails to function properly, it can lead to regurgitation, where stomach contents flow back into the esophagus, causing discomfort and potential damage to the esophageal lining.
Summary:
B: Loss of control of defecation is not related to the cardiac sphincter, as it primarily functions in the upper digestive tract.
C: Movement of the bolus into the trachea is related to swallowing reflex and epiglottis function, not the cardiac sphincter.
D: Rapid emptying from the stomach to the small intestine is controlled by the pyloric sphincter, not the cardiac sphincter.
