A patient who is scheduled for gastric bypass surgery asks for information about dumping syndrome. How does the nurse explain dumping syndrome?
An increase in the secretion of both bile and pancreatic enzymes
A decrease in the secretion of insulin caused by carbohydrates
When the passage of food into the small intestine occurs too rapidly
The inability to digest high-fat foods
The Correct Answer is C
A. Dumping syndrome is not related to the increased secretion of bile and pancreatic enzymes; it occurs when food passes too quickly from the stomach into the small intestine.
B. Dumping syndrome is not caused by a decrease in insulin secretion, but rather by rapid gastric emptying that can result in fluctuating blood sugar levels.
C. Dumping syndrome occurs when food moves too quickly from the stomach into the small intestine, causing a sudden release of insulin and other gastrointestinal symptoms, such as nausea, diarrhea, and dizziness.
D. While high-fat foods can be problematic for some gastric bypass patients, dumping syndrome is specifically related to rapid gastric emptying and not the inability to digest fat.

Correct Answer is C
Explanation
A. Discharge immediately following an open lung biopsy is unlikely. The patient will need observation post-procedure for complications such as bleeding, infection, or pneumothorax, and it usually requires a stay in the hospital for monitoring.
B. It is unlikely that supplemental oxygen will not be needed following an open lung biopsy. The patient may require oxygen post-procedure due to potential respiratory compromise, such as atelectasis or pneumothorax.
C. A chest tube is commonly inserted after an open lung biopsy to allow the lung to re-expand and to drain air or fluid that may accumulate in the pleural space. This is a standard part of the postoperative care for this procedure.
D. Collecting a sputum specimen is not typically necessary immediately after an open lung biopsy. The focus will be on monitoring the patient’s respiratory status, ensuring proper lung expansion, and preventing complications like pneumothorax or bleeding.
Correct Answer is B
Explanation
A. Constant bubbling in the suction-control chamber is normal as it indicates that the suction is active and functioning as intended. The chamber should have steady bubbling when suction is applied.
B. Continuous bubbling in the water-seal chamber is abnormal and indicates a potential air leak. The water-seal chamber should only bubble intermittently with respiratory effort or changes in pressure; constant bubbling suggests that air is being introduced into the system, which could indicate a malfunction or an air leak at the insertion site or along the tubing.
C. Fluid-level fluctuations in the water-seal chamber are normal and should be observed, especially with breathing. The fluid levels will rise with inspiration and fall with expiration, reflecting the changes in pressure within the pleural space.
D. Bloody drainage in the collection chamber is expected immediately after surgery, particularly in the early postoperative period. It may be a sign of surgical site drainage, but if it becomes excessive or persists, further assessment is required. However, a small amount of blood in the collection chamber initially is not abnormal.
