The nurse is preparing a client with Chronic Obstructive Pulmonary Disease (COPD) and a chronic productive cough for discharged home.

Which prescribed medication should the nurse review with the client to manage this symptom?

Terbinafine HCL is primarily metabolized by the liver, and a history of alcoholism may indicate liver dysfunction or damage, which could affect the metabolism and clearance of the drug. The nurse should assess the client's liver function, including liver enzymes, bilirubin levels, and albumin levels, before administering terbinafine HCL.

While options b, c, and d may be important assessment findings, they are not as crucial as a history of alcoholism when it comes to administering terbinafine HCL.

The thick and yellow toenails (option b) are typical symptoms of a fungal toenail infection, which is the reason for prescribing terbinafine HCL.

The white blood cell count (option c) is within normal range.

Being employed as a construction worker (option d) does not have a direct impact on the use of terbinafine HCL.

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.
