A nurse is administering naloxone to a patient who has overdosed on heroin. What is the expected outcome of this intervention?

The correct answer is choice A. Hepatic necrosis.Acetaminophen (APAP) is a common cause of drug-induced liver injury and can lead to hepatic necrosis, especially in patients who have chronic hepatitis C.APAP is metabolized by the liver and produces a toxic intermediate called N-acetyl-p-benzoquinone imine (NAPQI), which can deplete glutathione and damage hepatocytes.Patients who have chronic hepatitis C may have reduced glutathione levels and increased oxidative stress, making them more susceptible to APAP toxicity.

Choice B. Pulmonary fibrosis is wrong because APAP does not cause pulmonary fibrosis.

Pulmonary fibrosis is a chronic lung disease that involves scarring of the lung tissue and impaired gas exchange.Some drugs that can cause pulmonary fibrosis are amiodarone, bleomycin, methotrexate and nitrofurantoin.

Choice C. Pancreatitis is wrong because APAP does not cause pancreatitis.

Pancreatitis is an inflammation of the pancreas that can result from gallstones, alcohol abuse, hypertriglyceridemia, hypercalcemia, infections, trauma or certain medications.

Some drugs that can cause pancreatitis are azathioprine, valproic acid, didanosine and pentamidine.

Choice D. Cardiac dysrhythmias is wrong because APAP does not cause cardiac dysrhythmias.

Cardiac dysrhythmias are abnormal heart rhythms that can result from electrolyte imbalances, ischemia, myocardial infarction, heart failure, congenital defects or certain medications.

Some drugs that can cause cardiac dysrhythmias are digoxin, quinidine, sotalol and erythromycin.

The correct answer is choice A.Blurred vision is a common side effect of gabapentin and should be reported to the doctor.

Blurred vision can affect the patient’s ability to perform daily activities and may indicate a serious problem with the eyes or the brain.

Choice B is wrong because constipation is not a common side effect of gabapentin.

Constipation can be caused by other factors such as diet, dehydration, or lack of physical activity.

Choice C is wrong because dry mouth is a common side effect of gabapentin and does not usually require medical attention.

Dry mouth can be relieved by drinking water, chewing sugar-free gum, or using saliva substitutes.

Choice D is wrong because tinnitus is not a common side effect of gabapentin.

Tinnitus is a ringing or buzzing sound in the ears that can be caused by many conditions such as ear infections, hearing loss, or exposure to loud noises.
