A client with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?
Until a smaller angle can be restored.
For long-term control of normal eye pressure.
Until the excess pressure is reduced.
For long-term control of pain and swelling.
The Correct Answer is B
Open-angle glaucoma is a chronic eye condition that can cause irreversible damage to the optic nerve, leading to vision loss or blindness. The primary goal of treatment is to lower and control the intraocular pressure (IOP) to prevent further damage. Eye drops are often prescribed to reduce the IOP and are typically used for long-term control of normal eye pressure, even if the pressure has been reduced to a safe level.
Options a, c, and d are incorrect because they do not reflect the long-term management of open-angle glaucoma.
While reducing excess pressure may be a goal of treatment, it is not a guarantee that the eye drops will be discontinued once the pressure is normalized.
Likewise, restoring a smaller angle or managing pain and swelling may be secondary goals but are not the primary purpose of using eye drops in open-angle glaucoma

Correct Answer is C
Explanation
Baclofen is a muscle relaxant medication used to treat muscle spasticity, which is a condition that causes muscles to become stiff and rigid. It works by reducing the activity of nerves in the brain and spinal cord that cause muscle spasms.
Option a, using stool softener as needed, is appropriate because baclofen can cause constipation as a side effect.
Option b, avoiding ingestion of alcohol, is also appropriate because alcohol can increase the sedative effects of baclofen and cause drowsiness or dizziness.
Option d, taking medication with meals, is recommended because it can help reduce stomach upset and nausea that may occur as a side effect of the medication.
Option c, discontinuing the medication when spasms cease, is incorrect because muscle spasticity is a chronic condition, and baclofen is used to manage symptoms over a prolonged period. Discontinuing the medication abruptly can cause withdrawal symptoms and exacerbate the spasticity. Therefore, the nurse should educate the client to take the medication as prescribed by the healthcare provider and not discontinue it without medical advice.
Correct Answer is B
Explanation
Lactulose is a medication commonly used in the management of hepatic encephalopathy. It works by reducing the absorption of ammonia in the gut, which is a toxin that can accumulate in the blood in patients with liver dysfunction.
Monitoring serum electrolytes and ammonia levels can help the nurse evaluate the effectiveness of lactulose therapy. Elevated ammonia levels can indicate that the medication is not effectively reducing ammonia absorption and may require adjustment in dose or frequency. Additionally, monitoring electrolyte levels can help detect any imbalances that may occur because of lactulose therapy.
Fingerstick glucose levels (option A) are not relevant to evaluating the therapeutic response of lactulose in hepatic encephalopathy.
Stool color and character (option C) may be monitored to assess the side effects of lactulose, such as diarrhea, but are not the best assessments to evaluate therapeutic response.
Serum hepatic enzymes (option D) may be useful in assessing the severity of liver disease but are not the best assessment to evaluate the therapeutic response of lactulose in hepatic encephalopathy.
