A nurse is caring for a client who has a chest tube in place connected to a closed chest drainage system. Which of the following findings should indicate to the nurse that the client's lung has re-expanded?
Occasional bubbling in the water-seal chamber
No reports of pleuritic chest pain
No tidaling in the water-seal chamber
Oxygen saturation of 95%
The Correct Answer is C
Choice A reason: Occasional bubbling in the water-seal chamber can indicate an air leak, which is not necessarily a sign of lung re-expansion. It could suggest that the lung has not fully re-expanded or that there is a persistent air leak.
Choice B reason: While the absence of pleuritic chest pain is a positive sign, it is not a definitive indicator of lung re-expansion. Pleuritic chest pain can subside even if the lung has not fully re-expanded.
Choice C reason: No tidaling in the water-seal chamber is a strong indicator that the lung has re-expanded. When the lung is fully expanded, it presses against the chest wall, eliminating the space where air could collect and thus stopping the water level from fluctuating with respiration.
Choice D reason: An oxygen saturation of 95% is within normal limits and suggests adequate oxygenation, but it does not specifically indicate lung re-expansion. Oxygen saturation can be maintained with supplemental oxygen or other supportive measures even if the lung has not fully re-expanded.

Correct Answer is ["A","B","D"]
Explanation
Title: Choice A reason: Beta-blocking agent Beta-blocking agents are often used in the management of cirrhosis of the liver. They are particularly useful in managing portal hypertension, a common complication of cirrhosis. Beta-blockers lower elevated portal pressure and protect against variceal hemorrhage, a serious complication of portal hypertension. Therefore, a beta-blocking agent may be ordered for a client with cirrhosis of the liver.
Title: Choice B reason: Diuretic Diuretics are commonly used in the management of fluid retention, a frequent complication in patients with cirrhosis. Fluid retention can lead to conditions such as ascites (abdominal fluid accumulation) and edema (swelling in the legs, feet, or ankles)2. Diuretics help to remove excess fluid from the body, thereby managing these symptoms. Therefore, a diuretic may be ordered for a client with cirrhosis of the liver.
Title: Choice C reason: Opioid analgesic While opioid analgesics are powerful pain relievers, they should be used with caution in patients with cirrhosis of the liver. Opioids can precipitate hepatic encephalopathy, a condition characterized by altered mental status and neuromuscular dysfunction, which is a serious complication of cirrhosis. Therefore, an opioid analgesic may not be the best choice for a client with cirrhosis of the liver.
Title: Choice D reason: Lactulose Lactulose is a non-absorbable sugar that is widely used in the treatment of hepatic encephalopathy, a common complication in patients with cirrhosis. It works by reducing the absorption of ammonia in the gut, thereby lowering blood ammonia levels and improving symptoms of hepatic encephalopathy. Therefore, lactulose may be ordered for a client with cirrhosis of the liver.
Title: Choice E reason: Sedative Sedatives should be used with caution in patients with cirrhosis of the liver. Like opioids, they can precipitate hepatic encephalopathy. Therefore, a sedative may not be the best choice for a client with cirrhosis of the liver.
Correct Answer is A
Explanation
Choice A: Troponin Troponin levels increase within 3-12 hours from the onset of chest pain, peak at 24-48 hours, and return to baseline over 5-14 days. Troponin is a protein found in cardiac muscle fibers that regulates muscular contraction. When heart muscle is damaged, as in the case of an MI, troponin is released into the bloodstream. The elevation of troponin levels is a key indicator of myocardial infarction and can be used to diagnose and assess the extent of heart muscle damage. Troponin is the most reliable laboratory value that is expected to be elevated following a myocardial infarction, making it the correct choice in this scenario.
Choice B: Aspartate aminotransferase (AST) AST is an enzyme found in high concentrations in the liver, heart, muscles, kidneys, and brain. It is released into the bloodstream when any of these tissues are damaged. While AST can be elevated in cases of MI, it is not as specific as troponin because it is present in many other tissues besides the heart.
Choice C: Serum amylase Serum amylase is an enzyme that helps digest carbohydrates and is primarily associated with the pancreas and salivary glands. Its elevation is not specifically related to myocardial infarction but can be seen in other conditions such as pancreatitis.
Choice D: Unconjugated bilirubin Unconjugated bilirubin is a breakdown product of hemoglobin from red blood cells. Elevated levels of unconjugated bilirubin are typically associated with conditions affecting the liver or the breakdown of red blood cells, not myocardial infarction.
