HESI Pharmacology Quizlet

Correct Answer: C

Rationale: In portosystemic encephalopathy, the liver's ability to detoxify ammonia is impaired, leading to elevated blood ammonia levels, which can cause neurological symptoms such as encephalopathy. Lactulose is given to reduce ammonia levels by promoting its excretion through the bowel. Therefore, assessing the blood ammonia level is crucial to determine the effectiveness of lactulose therapy in managing portosystemic encephalopathy.

Correct Answer: D

Rationale: Aspirin or a nonsteroidal anti-inflammatory drug can be taken 30 minutes before taking the medication to decrease flushing. Alcohol consumption needs to be avoided because it will enhance this side effect. The medication should be taken with meals, this will decrease gastrointestinal upset. Taking the medication with meals has no effect on the flushing. Clay-colored stools are a sign of hepatic dysfunction and should be immediately reported to the health care provider (HCP).

Rationale: Clients taking warfarin (Coumadin) should avoid aspirin unless prescribed by their healthcare provider, as it can increase the risk of bleeding. The other statements are correct and do not indicate a need for further teaching. Taking aspirin along with warfarin can potentiate the anticoagulant effects of warfarin, leading to an increased risk of bleeding complications.
