A client with hepatic encephalopathy is receiving lactulose. Which assessment provides the nurse with the best information to evaluate the client's therapeutic response to the drug?
Stool color and character.
Serum electrolytes and ammonia.
Serum hepatic enzymes.
Fingerstick glucose.
The Correct Answer is B
Choice A reason: This is not the best assessment for the nurse to use to evaluate the client's therapeutic response to lactulose. Stool color and character may change as a result of lactulose administration, as it is a laxative that lowers the pH of the colon and promotes the excretion of ammonia. However, these changes are not indicative of the effectiveness of lactulose in reducing the ammonia levels in the blood, which is the main goal of the therapy.
Choice B reason: This is the best assessment for the nurse to use to evaluate the client's therapeutic response to lactulose. Serum electrolytes and ammonia are directly affected by lactulose administration, as it lowers the blood ammonia levels by converting it to ammonium and facilitating its elimination in the stool. The nurse should monitor the serum electrolytes and ammonia levels regularly to assess the efficacy and safety of lactulose therapy, as well as to adjust the dosage as needed.
Choice C reason: This is not the best assessment for the nurse to use to evaluate the client's therapeutic response to lactulose. Serum hepatic enzymes are markers of liver function and damage, and they may be elevated in clients with hepatic encephalopathy due to cirrhosis or other liver disorders. However, lactulose does not affect the hepatic enzymes directly, and it does not reverse the underlying liver disease. The nurse should monitor the serum hepatic enzymes to assess the progression and severity of the liver condition, but not to evaluate the response to lactulose.
Choice D reason: This is not the best assessment for the nurse to use to evaluate the client's therapeutic response to lactulose. Fingerstick glucose is a measure of blood glucose levels, and it may be altered in clients with hepatic encephalopathy due to impaired glucose metabolism by the liver. However, lactulose does not affect the blood glucose levels directly, and it does not improve the liver's ability to regulate glucose. The nurse should monitor the fingerstick glucose to assess the risk of hypoglycemia or hyperglycemia, but not to evaluate the response to lactulose.

Correct Answer is B
Explanation
Choice A reason: This is not the correct time to collect the peak and trough levels. The peak level should be measured after the completion of the IV dose, not during the administration. The trough level should be measured just before the next administration, not 30 minutes before.
Choice B reason: This is the correct time to collect the peak and trough levels. The peak level should be measured one hour after the completion of the IV dose, when the concentration of the medication is highest in the blood. The trough level should be measured one hour before the next administration, when the concentration of the medication is lowest in the blood.
Choice C reason: This is not the correct time to collect the peak and trough levels. The peak level should be measured one hour after the completion of the IV dose, not two hours after. The trough level should be measured one hour before the next administration, not two hours before.
Choice D reason: This is not the correct time to collect the peak and trough levels. The peak level should be measured one hour after the completion of the IV dose, not immediately after. The trough level should be measured one hour before the next administration, not 30 minutes before.
Correct Answer is D
Explanation
Choice A reason: Using the eye drops until the excess pressure is reduced is not an accurate response, as it implies that the eye drops are only a temporary treatment. Open-angle glaucoma is a chronic condition that causes increased pressure in the eye due to impaired drainage of the aqueous humor. The eye drops are used to lower the eye pressure and prevent further damage to the optic nerve. The client will need to use the eye drops for the rest of their life, unless the healthcare provider advises otherwise.
Choice B reason: Using the eye drops for long-term control of pain and swelling is not an accurate response, as it does not address the main goal of the treatment. Open-angle glaucoma does not usually cause pain or swelling, as the pressure builds up gradually and painlessly. The eye drops are used to lower the eye pressure and prevent vision loss, not to relieve inflammation or discomfort.
Choice C reason: Using the eye drops until a smaller angle can be restored is not an accurate response, as it confuses open-angle glaucoma with closed-angle glaucoma. Open-angle glaucoma is characterized by a wide and open angle between the iris and the cornea, which allows the aqueous humor to flow freely. Closed-angle glaucoma is characterized by a narrow or closed angle that blocks the drainage of the aqueous humor. The eye drops are used to lower the eye pressure and prevent further damage to the optic nerve, not to change the angle of the eye.
Choice D reason: Using the eye drops for long-term control of normal eye pressure is the most accurate response, as it reflects the purpose and duration of the treatment. Open-angle glaucoma is a chronic condition that requires lifelong management. The eye drops are used to lower the eye pressure and prevent vision loss, which can occur if the pressure is too high for too long. The client should use the eye drops as prescribed and follow up with the healthcare provider regularly.
