A client with hepatic encephalopathy is receiving lactulose. Which assessment provides the nurse with the nest information to evaluate the client’s therapeutic response to the drug?

Fingerstick glucose.

Serum electrolytes and ammonia.

Stool color and character.

Serum hepatic enzymes.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

Gentamicin sulfate is an aminoglycoside antibiotic that can cause ototoxicity, which is damage to the inner ear leading to hearing loss or balance problems. Therefore, a decrease in hearing is an indication that the client may be experiencing an adverse eﬀect of gentamicin.

Option b, decreased blood urea nitrogen, is not an adverse eﬀect of gentamicin, but it may indicate improvement in kidney function, which can be a positive outcome of treatment.

Option c, a white blood cell count of 6,000/mm3 (6x109/L), is within the normal range and is not necessarily an adverse eﬀect of gentamicin.

Option d, photophobia, is not a common adverse eﬀect of gentamicin and may indicate a diﬀerent condition or medication eﬀect.

A. Remove the morphine patches. B. Monitor blood pressure. C. Apply oxygen face mask. D. Administer a narcotic reversal drug.

Correct Answer is A

Explanation

The client’s symptoms of being short of breath and difficult to arouse may indicate an overdose of morphine. The nurse should immediately remove the patches to prevent further absorption of the drug. After removing the patches, the nurse should continue to assess the client’s condition and take further actions as needed, such as administering a narcotic reversal drug or providing oxygen.
