A nurse is preparing to administer a dose of lactulose to a client diagnosed with cirrhosis. The client states, "I don't need this medication. I am not constipated." The nurse should explain that in clients who have cirrhosis, lactulose is used to decrease levels of which of the following components in the bloodstream?
Potassium
Ammonia
Glucose
Bicarbonate
The Correct Answer is B
A. Lactulose is not used to decrease potassium levels. It is a laxative that works by drawing water into the colon, softening stools and promoting bowel movements.
B. Lactulose is used to decrease ammonia levels in clients with cirrhosis. Ammonia is a byproduct of protein metabolism, and when the liver is compromised, it may not effectively convert ammonia into urea, leading to elevated ammonia levels in the bloodstream. Lactulose helps reduce ammonia absorption in the colon.
C. Lactulose does not decrease glucose levels significantly. It is not primarily used as an antidiabetic medication.
D. Lactulose does not affect bicarbonate levels significantly. It primarily targets ammonia reduction in clients with cirrhosis.

Correct Answer is D
Explanation
A. COPD (Chronic Obstructive Pulmonary Disease) is not directly associated with acute pancreatitis. The common risk factors for acute pancreatitis include gallstones, alcohol use, and certain medications.
B. Hypolipidemia (low blood lipid levels) is not a typical factor associated with acute pancreatitis. Elevated levels of lipids in the blood (hyperlipidemia) can be a risk factor, but hypolipidemia is not commonly linked to pancreatitis.
C. Diabetes mellitus, while not a direct cause of acute pancreatitis, can be associated with an increased risk. Uncontrolled diabetes may contribute to the development of pancreatitis, but it is not a primary risk factor.
D. Gallstones are a significant risk factor for acute pancreatitis. Gallstones can obstruct the pancreatic duct, leading to inflammation and damage to the pancreas. This obstruction is one of the common causes of acute pancreatitis.
Correct Answer is B
Explanation
A. Level of consciousness:
While assessing the client's level of consciousness is important, it is not the top priority after an EGD procedure unless there are specific signs of neurological distress. Monitoring for signs of sedation or anesthesia recovery is typically part of post-procedure care.
B. Gag reflex:
This is the correct answer. The nurse should prioritize assessing the gag reflex, as the procedure involves passing a flexible tube through the mouth and down the esophagus. Ensuring the return of the gag reflex is essential to prevent aspiration and ensure the client's safety.
C. Pain:
Pain assessment is important, but it is usually addressed after confirming airway protection and ensuring the absence of complications such as bleeding or perforation.
D. Nausea:
While nausea is a possible post-procedure symptom, assessing the gag reflex and monitoring for signs of complications take precedence over managing nausea in the immediate post-procedure period.
