Before administering a newly prescribed dose of terbinafine HCL to a client with a fungal toenail infection, which assessment finding is most important for the nurse to address?
Reported history of alcoholism.
Toenails appear thick and yellow.
Employed as a construction worker.
White blood cell count of 8,500/mm³ (8.5 x 10⁹/L).
The Correct Answer is A
Choice A rationale
Reported history of alcoholism is the most important assessment finding to address before administering terbinafine HCL. Terbinafine is metabolized by the liver, and clients with a history of alcoholism may have impaired liver function, increasing the risk of hepatotoxicity. Monitoring liver function and assessing for signs of liver damage are crucial before starting treatment.
Choice B rationale
Toenails appear thick and yellow is a common symptom of fungal toenail infection, but it is not the most critical assessment finding to address before administering terbinafine HCL. The focus should be on assessing liver function.
Choice C rationale
Employed as a construction worker is not the most critical assessment finding to address before administering terbinafine HCL. While occupational exposure to fungi may be relevant, the primary concern is liver function.
Choice D rationale
White blood cell count of 8,500/mm³ (8.5 x 10⁹/L) is within the normal range and is not the most critical assessment finding to address before administering terbinafine HCL. The primary concern is liver function.

Correct Answer is A
Explanation
Choice A rationale
Lactulose is a synthetic sugar used to treat hepatic encephalopathy by reducing the absorption of ammonia in the intestines. Ammonia is a neurotoxin that can impair mental status in patients with liver dysfunction. By decreasing ammonia levels, lactulose helps improve cognitive function and mental status in patients with hepatic encephalopathy.
Choice B rationale
While lactulose can cause diarrhea as a side effect, the therapeutic goal in hepatic encephalopathy is not to reduce the number of liquid stools but to lower ammonia levels in the blood. The reduction in ammonia levels leads to improved mental status, not necessarily a reduction in liquid stools.
Choice C rationale
The ability to ambulate independently is not a direct therapeutic response to lactulose. The primary goal of lactulose therapy in hepatic encephalopathy is to improve mental status by reducing ammonia levels, not to enhance physical mobility.
Choice D rationale
Lactulose does not have a direct effect on urine output. Its primary mechanism of action is to reduce ammonia absorption in the intestines, thereby improving mental status in patients with hepatic encephalopathy.
Correct Answer is C
Explanation
Choice A rationale
Increasing the frequency of dressing changes may not be necessary and could potentially disrupt the healing process. The type of dressing used is more important for managing the wound.
Choice B rationale
Leaving the dressing off until consulting with the healthcare provider is not recommended as it can expose the wound to infection and delay healing.
Choice C rationale
Applying a hydrocolloidal gel dressing is appropriate for a stage 3 pressure injury with significant granulation. Hydrocolloidal dressings provide a moist environment that promotes healing and protects the wound from contamination.
Choice D rationale
Replacing the gauze with a transparent dressing may not provide the necessary moisture and protection for a stage 3 pressure injury. Hydrocolloidal dressings are more suitable for this type of wound.
