A client has been administered lactulose for several days.
Which therapeutic response should the nurse expect for a client with hepatic encephalopathy?
Improved mental status.
Increase in urine output.
Reduction in number of liquid stools.
Ability to ambulate independently.
The Correct Answer is A
Choice A rationale:
Lactulose directly addresses the primary cause of hepatic encephalopathy, which is the accumulation of ammonia in the blood. Ammonia is a neurotoxin that can impair brain function, leading to confusion, lethargy, and even coma. Lactulose works by trapping ammonia in the colon, where it can be safely excreted in the stool. This decrease in ammonia levels in the blood allows for the improvement of mental status.
Studies have consistently shown that lactulose therapy can significantly improve mental function in patients with hepatic encephalopathy. This improvement is often seen within a few days of starting treatment.
The nurse should assess the client's mental status regularly to monitor for improvement. This assessment should include evaluating the client's level of consciousness, orientation, attention, memory, and speech.
Improved mental status is a critical therapeutic goal in the treatment of hepatic encephalopathy. It allows patients to regain their independence and participate more fully in their care.
Choice B rationale:
While lactulose can cause diarrhea, which may lead to a slight increase in urine output, this is not the primary therapeutic response that the nurse should expect.
The increase in urine output is typically secondary to the diarrhea and does not directly reflect a reduction in ammonia levels or improvement in mental status.
Choice C rationale:
Lactulose does cause diarrhea, which is a common side effect of the medication.
However, the goal of lactulose therapy is not to reduce the number of liquid stools but rather to trap ammonia in the colon and promote its excretion.
The nurse should monitor the client's stool frequency and consistency to ensure that they are not experiencing excessive diarrhea, which could lead to dehydration and electrolyte imbalances.
Choice D rationale:
While improved mental status may eventually lead to improved mobility, it is not the most immediate or direct therapeutic response that the nurse should expect from lactulose therapy.
The ability to ambulate independently is more likely to be a long-term goal of treatment, rather than an immediate response to lactulose.

Correct Answer is A
Explanation
Rationale for Choice A:
Direct (sliding) hiatal hernias: These are the most common type of hiatal hernia. They occur when the upper part of the stomach slides upward through the diaphragm into the chest cavity. This displacement disrupts the normal function of the lower esophageal sphincter (LES), which is a ring of muscle that acts as a valve between the esophagus and stomach. The LES is responsible for preventing stomach contents from refluxing back into the esophagus.
Esophageal reflux: When the LES is weakened or impaired, stomach acid, pepsin, and bile can flow back into the esophagus, causing a burning sensation known as heartburn, regurgitation of food or sour liquid, and irritation of the esophageal lining.
Prevention of esophageal reflux: Nursing actions aimed at preventing esophageal reflux are crucial in the management of hiatal hernias. These actions include:
Elevate the head of the bed: This helps to keep stomach contents below the level of the esophagus, reducing the risk of reflux. Avoid eating large meals: Large meals put more pressure on the stomach, which can increase the likelihood of reflux.
Avoid lying down after eating: Lying down can allow stomach contents to flow back into the esophagus more easily. Avoid foods that trigger reflux: Common triggers include fatty foods, spicy foods, acidic foods, caffeine, and alcohol.
Maintain a healthy weight: Excess weight can increase abdominal pressure and contribute to reflux.
Consider medications: If lifestyle changes are not enough to control reflux, medications such as antacids, H2 blockers, or proton pump inhibitors may be prescribed.
Rationale for Choice B:
Maintaining intact oral mucosa: This is not a primary goal in the care of a client with a hiatal hernia. While oral hygiene is important for overall health, it does not directly address the issue of esophageal reflux.
Rationale for Choice C:
Increasing intestinal peristalsis: This is not a relevant goal for a hiatal hernia. Hiatal hernias primarily affect the upper digestive tract, not the intestines.
Rationale for Choice D:
Promoting effective swallowing: This is not the most important goal in the care of a client with a hiatal hernia. While swallowing difficulties can occur in some cases, they are not the primary concern. The priority is to prevent esophageal reflux and its associated complications.
Correct Answer is D
Explanation
Choice A rationale:
Observing the skin for lesions is not a specific technique for assessing early signs of rheumatoid arthritis. While RA can sometimes manifest with skin lesions, they are not typically present in the early stages of the disease. Moreover, skin lesions can be indicative of a wide range of other conditions, making them a less reliable indicator of RA.
Choice B rationale:
Palpating the lymph nodes is also not a specific technique for assessing early signs of rheumatoid arthritis. Lymph node enlargement can occur in various inflammatory conditions, including infections and autoimmune diseases. It is not a characteristic feature of early RA.
Choice C rationale:
Palpating large joints for nodules is a technique used to assess for rheumatoid arthritis, but it is more likely to detect nodules in later stages of the disease. Nodules are typically firm, non-tender bumps that develop under the skin around joints. They are often found in areas like the elbows, knuckles, and fingers. However, they may not be present in the early stages of RA.
Choice D rationale:
Observing the client's fingers is the most appropriate technique for assessing early signs of rheumatoid arthritis. This is because the fingers are often the first joints to be affected by the disease. Early signs of RA in the fingers can include:
Swelling of the finger joints, particularly the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints. Tenderness and pain in the finger joints, especially upon movement.
Stiffness in the finger joints, which is often worse in the mornings and after periods of inactivity. Redness or warmth in the finger joints.
Difficulty bending or straightening the fingers.
