The healthcare provider prescribes lactulose for a patient with hepatic encephalopathy. What will the nurse assess to determine the effectiveness of this medication?
Decreased ammonia levels
Relief of constipation
Decreased liver enzymes
Relief of abdominal pain
The Correct Answer is A
Choice A reason:Lactulose is used in hepatic encephalopathy primarily to lower blood ammonia levels. It works by converting ammonia in the intestines into ammonium, which is then excreted³. Therefore, a decrease in ammonia levels would indicate the effectiveness of the medication.
Choice B reason:While lactulose can relieve constipation due to its laxative effect, relief of constipation is not the primary indicator of its effectiveness in treating hepatic encephalopathy³.
Choice C reason:Decreased liver enzymes are not a direct measure of lactulose's effectiveness in hepatic encephalopathy. Liver enzymes are indicators of liver function, not ammonia levels³.
Choice D reason:Relief of abdominal pain is not a specific indicator of lactulose's effectiveness in hepatic encephalopathy. The medication's primary role is to reduce ammonia levels, not to alleviate pain³.

Explanation
Tachycardia, or a rapid heartbeat, is a common response to the pain and stress associated with stomach perforation. The body’s sympathetic nervous system is activated in response to the pain and the potential shock state due to internal bleeding or infection, leading to an increased heart rate. Tachycardia is also a compensatory mechanism to maintain adequate blood flow and oxygen delivery to vital organs in the setting of decreased blood volume. A stomach perforation due to a peptic ulcer is a serious medical condition where an ulcer has led to a hole in the stomach lining. This can lead to the contents of the stomach spilling into the abdominal cavity, causing peritonitis, which is an inflammation of the peritoneum (the lining of the abdominal cavity).
Choice B: Rebound tenderness
Rebound tenderness is a clinical sign that indicates irritation of the peritoneum. When pressure is applied to the abdomen and then quickly released, the sudden movement of the peritoneal layers against each other produces sharp, rebound pain. This is a classic sign of peritonitis, which can occur with stomach perforation as gastric contents irritate the peritoneum. When assessing a client with a suspected stomach perforation due to a peptic ulcer, a nurse should expect to find signs of tachycardia, rebound tenderness, and a rigid abdomen. These findings are indicative of the body’s response to the acute abdominal condition and peritoneal irritation. It is crucial to recognize these signs promptly as stomach perforation is a medical emergency requiring immediate intervention.
Choice C: Rigid abdomen
A rigid abdomen is indicative of involuntary guarding, a reflex contraction of the abdominal muscles to protect inflamed organs within the abdomen. This rigidity is a sign of peritoneal irritation and is often present in cases of stomach perforation. The rigidity helps to immobilize the area, which may reduce pain but also serves as a clinical indicator of serious intra-abdominal pathology.
Choice D: Elevated blood pressure
Elevated blood pressure is not typically a direct result of stomach perforation. In fact, blood pressure may initially be normal or even low, depending on the body’s response to internal bleeding and the potential development of shock. However, pain and anxiety can cause a transient increase in blood pressure, but it is not a primary diagnostic criterion for stomach perforation.

Explanation
Choice A: Bradycardia Bradycardia, or a slower than normal heart rate, is not typically a direct symptom of flail chest. While traumatic injuries can lead to various cardiac responses, bradycardia is not commonly associated with the respiratory distress seen in flail chest. Flail chest is a serious condition that occurs when a segment of the rib cage breaks due to trauma and becomes detached from the rest of the chest wall. This can severely affect breathing and lead to other complications.
Choice B: Anxiety Anxiety is a common response in patients with flail chest due to the pain and difficulty in breathing associated with the condition. The stress of the injury and the body’s response to the trauma can lead to feelings of anxiety and panic.
Choice C: Dyspnea Dyspnea, or difficulty breathing, is one of the primary symptoms of flail chest. The instability of the chest wall and the paradoxical movement of the flail segment impair the normal mechanics of breathing, leading to shortness of breath.
Choice D: Unequal chest expansion Unequal chest expansion is a hallmark sign of flail chest. The affected area of the chest wall moves in the opposite direction to the rest of the chest during the respiratory cycle, which can be observed as an abnormal movement during inhalation and exhalation.
Choice E: Hypotension Hypotension, or low blood pressure, can occur in flail chest cases, especially if there is associated trauma such as bleeding or if the patient is in shock. The body’s response to the injury and the potential for compromised venous return due to the chest wall’s dysfunction can lead to hypotension.
Choice F: Paradoxical chest movement Paradoxical chest movement is a definitive sign of flail chest. It occurs when the broken section of the rib cage moves inward during inhalation and outward during exhalation, opposite to the normal chest movement. This is due to the loss of stability in the chest wall and is easily observable during a physical examination. Flail chest is a critical condition that requires immediate medical attention. The signs and symptoms associated with this condition include anxiety, dyspnea, unequal chest expansion, hypotension, and paradoxical chest movement. These symptoms reflect the underlying pathophysiology of the condition, which is the instability of the chest wall and the resulting impairment of normal respiratory function.
