When teaching a patient who is beginning antilipemic therapy about possible drug-food interactions, the nurse will discuss which food?

Correct Answer: B

Rationale: The nurse will discuss grapefruit juice when teaching a patient about possible drug-food interactions with antilipemic therapy. Grapefruit juice can inhibit the enzyme CYP3A4 in the liver, which can affect the metabolism of certain medications, including some antilipemic drugs. This interaction may lead to increased drug levels in the bloodstream, potentially causing harmful side effects. It is important for patients to be aware of this interaction and to consult their healthcare provider if they consume grapefruit juice while on antilipemic therapy.

Correct Answer: B

Rationale: Garlic is known to have antiplatelet and anticoagulant properties. When taken in large amounts, garlic can enhance the effects of anticoagulant medications like warfarin (Coumadin), which can increase the risk of bleeding. Therefore, it is crucial for patients on warfarin therapy to avoid consuming excessive amounts of garlic or garlic supplements to prevent potential interactions and complications.

Correct Answer: B

Rationale: Heparin is an anticoagulant medication used to prevent blood clots. If a patient on heparin therapy experiences excessive bleeding or needs to quickly reverse the anticoagulant effects of heparin, the antidote is protamine sulfate. Protamine sulfate works by neutralizing the effects of heparin by forming a complex with it. It is important for healthcare providers to have protamine sulfate readily available when managing patients on heparin therapy to effectively reverse its anticoagulant effects in emergency situations.

Correct Answer: A

Rationale: Acetaminophen (Tylenol) is primarily metabolized in the liver. Hepatotoxicity is a serious potential side effect of acetaminophen overdose or excessive use. One of the markers for liver damage due to acetaminophen toxicity is an elevated blood urea nitrogen (BUN) level. Normal BUN levels range from 7 to 20 mg/dl, and a level of 60 mg/dl indicates kidney dysfunction, which can result from liver damage caused by acetaminophen toxicity. Therefore, an elevated BUN level would indicate a toxicity of acetaminophen in this client with Bell's palsy who is taking acetaminophen daily. The other laboratory values mentioned are not specific markers for acetaminophen toxicity.

Correct Answer: D

Rationale: Valproate is an anticonvulsant medication commonly used to treat seizure disorders such as epilepsy. It works by stabilizing electrical activity in the brain, which helps to reduce the occurrence of seizures. Therefore, the expected outcome of Valproate treatment is a decrease in seizure activity and an improvement in seizure control.
