The nurse is taking care of a client diagnosed with advanced liver disease with hepatic encephalopathy. Lactulose (Cephulac) is administered to the patient to reduce which of the following?
A. Ammonia
Lactulose is administered to patients with hepatic encephalopathy to reduce the levels of ammonia in the blood. Hepatic encephalopathy occurs due to the liver’s inability to detoxify ammonia, a byproduct of protein metabolism. Lactulose works by converting ammonia into ammonium, which is then excreted in the stool. This helps to lower blood ammonia levels and alleviate the symptoms of hepatic encephalopathy.
B. Muscle rigidity
e Rigidity Muscle rigidity is one of the hallmark symptoms of Parkinson’s disease. It refers to the stiffness and inflexibility of the muscles, which can affect any part of the body. This rigidity can lead to discomfort and pain, and it contributes to the characteristic stooped posture and shuffling gait seen in Parkinson’s patients.
C. Seizures
Seizures are not typically associated with Parkinson’s disease. While Parkinson’s affects the central nervous system, it primarily impacts motor function rather than causing seizure activity. Therefore, this is not a common finding in Parkinson’s patients.
D. Drooling at times
Drooling, or sialorrhea, is a common symptom in Parkinson’s disease. It occurs due to the decreased ability to swallow saliva, which can result from muscle rigidity and bradykinesia affecting the muscles involved in swallowing. This can be particularly bothersome for patients and may require management strategies.
E. Mask-like facial expression
A mask-like facial expression, also known as hypomimia, is a common feature of Parkinson’s disease. It results from the rigidity and bradykinesia affecting the facial muscles, leading to reduced facial expressions and a fixed, staring appearance.
F. Shuffled gait
A shuffled gait is a characteristic feature of Parkinson’s disease. Patients often take small, shuffling steps and may have difficulty initiating movement. This gait pattern is due to the combination of muscle rigidity, bradykinesia, and postural instability.

Full Explanation
Choice A: Ammonia
Lactulose is administered to patients with hepatic encephalopathy to reduce the levels of ammonia in the blood. Hepatic encephalopathy occurs due to the liver’s inability to detoxify ammonia, a byproduct of protein metabolism. Lactulose works by converting ammonia into ammonium, which is then excreted in the stool. This helps to lower blood ammonia levels and alleviate the symptoms of hepatic encephalopathy.
Choice B: Dysarthria
Dysarthria, or difficulty in articulating words, is a common symptom of Parkinson’s disease. It results from the muscle rigidity and bradykinesia (slowness of movement) that affect the muscles involved in speech. Patients with Parkinson’s often have a soft, monotone voice and may struggle with the clarity of their speech.
Choice C: Muscle Rigidity
Muscle rigidity is one of the hallmark symptoms of Parkinson’s disease. It refers to the stiffness and inflexibility of the muscles, which can affect any part of the body. This rigidity can lead to discomfort and pain, and it contributes to the characteristic stooped posture and shuffling gait seen in Parkinson’s patients.

Choice G: Shuffled Gait
A shuffled gait is a characteristic feature of Parkinson’s disease. Patients often take small, shuffling steps and may have difficulty initiating movement. This gait pattern is due to the combination of muscle rigidity, bradykinesia, and postural instability.
Choice H: Stooped Posture
Stooped posture is another common symptom of Parkinson’s disease. It results from the muscle rigidity and postural instability that affect the patient’s ability to maintain an upright position. This can lead to a forward-leaning posture and balance issues.
Similar Questions
A client has been admitted with new-onset status epilepticus. Which seizure precautions would the nurse implement? (Select all that apply.)
A. Suction equipment at the bedside.
: Suction equipment at the bedside. Having suction equipment at the bedside is crucial for a client with status epilepticus. During a seizure, there is a risk of aspiration due to excessive salivation or vomiting. Suction equipment allows the nurse to quickly clear the airway, preventing aspiration and ensuring the client can breathe properly. This precaution is essential to maintain the client’s airway and prevent complications such as aspiration pneumonia.
B. Continuous sedation.
: Continuous sedation. Continuous sedation is not typically a standard precaution for all clients with status epilepticus. While sedation may be necessary in some cases to control seizures, it is not a universal precaution. The primary goal is to stop the seizure activity and stabilize the client. Continuous sedation may be used in specific situations under close medical supervision, but it is not a general precaution that nurses implement for all clients with status epilepticus.
C. Side rails padded.
: Side rails padded. Padding the side rails of the bed is an important precaution to prevent injury during a seizure. Clients experiencing seizures may have uncontrolled movements, which can lead to injury if they hit the hard surfaces of the bed. Padded side rails help to cushion these impacts, reducing the risk of bruises, cuts, or fractures. This precaution is essential for ensuring the client’s safety during seizure activity.
D. Bed in low position.
: Bed in low position. Keeping the bed in a low position is another important safety measure. If a client with status epilepticus were to fall out of bed during a seizure, the lower height reduces the risk of serious injury. This precaution helps to minimize the impact of any potential falls, ensuring the client’s safety. It is a simple yet effective measure to prevent harm during seizure episodes.
E. Intravenous (IV) access.
: Intravenous (IV) access. Establishing intravenous (IV) access is critical for a client with status epilepticus. IV access allows for the rapid administration of medications needed to control seizures and manage the client’s condition. In an emergency, quick access to the bloodstream is essential for delivering life-saving treatments. This precaution ensures that the medical team can promptly and effectively intervene to stop the seizure activity.

During a routine medical evaluation, a client is found to have a random blood glucose level of 310 mg/dL. Which client statements are concerning to the nurse? Select all that apply.
A. I sleep at least 8 hours each night.
: I sleep at least 8 hours each night. This statement is not concerning because getting adequate sleep is generally a sign of good health. It does not directly relate to symptoms of high blood glucose levels. Therefore, this choice is not relevant to the nurse’s concerns regarding the client’s elevated blood glucose level.
B. I cannot seem to quench my thirst.
: I cannot seem to quench my thirst. This statement is concerning because excessive thirst, known as polydipsia, is a common symptom of high blood glucose levels or hyperglycemia. When blood glucose levels are elevated, the body tries to eliminate the excess glucose through urine, leading to dehydration and increased thirst. This symptom indicates that the client’s blood glucose levels may be poorly controlled, which requires medical attention.
C. I have to void nearly every hour.
: I have to void nearly every hour. Frequent urination, or polyuria, is another symptom of high blood glucose levels. When there is too much glucose in the blood, the kidneys work harder to filter and absorb it. When they can’t keep up, the excess glucose is excreted into the urine, pulling fluids from the tissues and causing frequent urination. This symptom is a clear indicator of hyperglycemia and needs to be addressed by the nurse.
D. At times my vision is blurry.
: At times my vision is blurry. Blurred vision can be a symptom of high blood glucose levels. Elevated glucose levels can cause the lens of the eye to swell, leading to changes in vision. This symptom is concerning because it suggests that the client’s blood glucose levels are affecting their vision, which can be a sign of poorly managed diabetes or other complications.
E. I have lost 10 pounds without even trying.
: I have lost 10 pounds without even trying. Unintentional weight loss is a concerning symptom of high blood glucose levels. When the body cannot use glucose for energy due to insulin resistance or lack of insulin, it starts to break down muscle and fat for energy, leading to weight loss. This symptom indicates that the client’s diabetes may be uncontrolled, and immediate medical intervention is necessary.

An acute care nurse receives a shift report for a client who has increased intracranial pressure. The nurse is told that the client demonstrates decorticate posturing. Which of the following findings should the nurse expect to observe when assessing the client?
A. Pronation of the hands.
: Pronation of the hands. Pronation of the hands is not typically associated with decorticate posturing. Decorticate posturing is characterized by the flexion of the arms and wrists, with the hands often clenched into fists. Pronation refers to the rotation of the hands so that the palms face downward, which is not a feature of decorticate posturing.
B. Extension of the arms.
: Extension of the arms. Extension of the arms is more characteristic of decerebrate posturing, not decorticate posturing. In decorticate posturing, the arms are flexed and held tightly to the chest, not extended. This flexion is due to damage to the cerebral hemispheres, which affects the corticospinal tract.
C. External rotation of the lower extremities.
: External rotation of the lower extremities. External rotation of the lower extremities is not a typical finding in decorticate posturing. In decorticate posturing, the legs are usually extended and rigid, with the toes pointed. External rotation would indicate a different type of posturing or neurological condition.
D. Plantar flexion of the legs.
: Plantar flexion of the legs. Plantar flexion of the legs is a characteristic finding in decorticate posturing. This involves the toes pointing downward, which is a result of the increased muscle tone and reflexes due to the brain injury. This posture indicates severe damage to the brain, specifically the corticospinal tract.
