The nurse is caring for a client diagnosed with chronic hepatitis who is receiving the medication lactulose. Which of these laboratory results would indicate the medication is achieving the desired therapeutic effect?
Increased serum albumin
Decreased serum bilirubin
Decreased serum ammonia
Decreased serum alanine aminotransferase (ALT)
The Correct Answer is C
Choice A Reason: Increased Serum Albumin
Increased serum albumin is not a direct indicator of the therapeutic effect of lactulose in patients with chronic hepatitis. Albumin is a protein made by the liver, and its levels can be affected by liver function. However, lactulose primarily works by reducing ammonia levels in the blood, not by increasing albumin levels. Normal serum albumin levels range from 3.5 to 5.5 grams per deciliter (g/dL). While improved liver function might eventually lead to increased albumin levels, this is not the primary therapeutic effect of lactulose.
Choice B Reason: Decreased Serum Bilirubin
Decreased serum bilirubin is also not a direct indicator of lactulose’s therapeutic effect. Bilirubin is a byproduct of the normal breakdown of red blood cells and is processed by the liver. Elevated bilirubin levels can indicate liver dysfunction, but lactulose’s main role is to reduce ammonia levels, not bilirubin. Normal serum bilirubin levels are typically between 0.1 to 1.2 milligrams per deciliter (mg/dL). While improved liver function might reduce bilirubin levels, this is not the primary goal of lactulose therapy.
Choice C Reason: Decreased Serum Ammonia
Decreased serum ammonia is the correct indicator of the therapeutic effect of lactulose in patients with chronic hepatitis. Lactulose is used to treat hepatic encephalopathy, a condition caused by high levels of ammonia in the blood due to liver dysfunction. Lactulose works by converting ammonia into ammonium, which is then excreted from the body. Normal serum ammonia levels are less than 50 micromoles per liter (µmol/L) in adults56. A decrease in serum ammonia levels indicates that lactulose is effectively reducing the toxic levels of ammonia in the blood, thereby achieving its desired therapeutic effect.
Choice D Reason: Decreased Serum Alanine Aminotransferase (ALT)
Decreased serum alanine aminotransferase (ALT) is not a direct indicator of lactulose’s therapeutic effect. ALT is an enzyme found in the liver that helps convert proteins into energy for liver cells. Elevated ALT levels can indicate liver damage. Normal ALT levels range from 7 to 56 units per liter (U/L). While improved liver function might reduce ALT levels, lactulose’s primary role is to reduce ammonia levels, not directly affect ALT.

Related Questions
Correct Answer is ["C","E"]
Explanation
Choice A: Formed stool in collection pouch
Formed stool in the collection pouch is not expected in an ileostomy. The output from an ileostomy is typically liquid to semi-liquid because the ileum does not absorb as much water as the colon. If formed stool is present, it may indicate a blockage or other issue that needs to be addressed.
Choice B: Stoma is edematous and bleeding
An edematous and bleeding stoma is not a normal finding and may indicate complications such as infection, trauma, or poor stoma care. The stoma should be moist and pink, but not swollen or bleeding. Persistent bleeding or significant edema should be reported to a healthcare provider immediately.
Choice C: Stoma is pink and shiny
A pink and shiny stoma is a sign that the ileostomy is functioning well. This indicates good blood flow and healthy tissue. The stoma should always appear moist and pink, similar to the inside of the mouth. Any deviation from this appearance, such as a pale, dark, or dry stoma, should be evaluated by a healthcare professional.
Choice D: Skin excoriation around the stoma
Skin excoriation around the stoma is not a normal finding and suggests that the skin is being irritated by the stoma output or the ostomy appliance. Proper skin care and fitting of the ostomy appliance are essential to prevent skin breakdown. If excoriation occurs, it should be treated promptly to prevent further complications.
Choice E: Mucus liquid flows from the stoma
Mucus liquid flowing from the stoma is expected in an ileostomy. The output is typically liquid to semi-liquid and may contain mucus, which is normal for the small intestine. This type of output indicates that the ileostomy is functioning as intended.
Correct Answer is D
Explanation
Choice A: Rosebud-like Stoma Orifice
A rosebud-like stoma orifice is typically a normal appearance for a new stoma. The stoma should be moist, pink to red in color, and protrude slightly from the abdomen, resembling a rosebud. This appearance indicates good blood flow and proper healing. Therefore, this finding does not usually require immediate reporting to the provider.
Choice B: Stoma Oozing Red Drainage
While some minor bleeding or oozing can be normal immediately after surgery, persistent or significant red drainage from the stoma could indicate a complication such as infection or trauma to the stoma site. This finding should be monitored closely, but it is not as immediately concerning as a purplish-colored stoma, which indicates a more severe issue.
Choice C: Shiny, Moist Stoma
A shiny, moist stoma is a sign of a healthy stoma. The stoma should always appear moist and slightly shiny due to the mucus produced by the intestinal lining. This finding is normal and does not require reporting to the provider.
Choice D: Purplish-Colored Stoma
A purplish-colored stoma is an immediate concern and should be reported to the provider. This discoloration can indicate compromised blood flow to the stoma, which can lead to tissue necrosis if not addressed promptly. Ensuring adequate blood supply is crucial for the stoma’s viability and the patient’s overall health. Immediate medical intervention is necessary to prevent further complications.
