A nurse is providing discharge instructions to a client who has asthma and is about to start taking theophylline (Theo-24). The nurse should tell the client that this medication might cause which of the following adverse effects?

Acetaminophen is generally considered safe and well-tolerated when used appropriately. However, it is primarily metabolized by the liver, and in cases of severe hepatic impairment or liver failure, the metabolism of acetaminophen can be significantly impaired. This can lead to the accumulation of toxic metabolites, which can cause further liver damage and potentially result in hepatotoxicity.

Hypertension, gallbladder disease, and tachyarrhythmias are not typically considered contraindications for the use of acetaminophen. However, it is important to consider any potential interactions or precautions when using acetaminophen in patients with these conditions, and consulting with a healthcare provider is recommended to ensure the safe and appropriate use of the medication.

Nasal glucocorticoids, also known as intranasal corticosteroids, are considered the most effective and recommended first-line treatment for nasal congestion caused by allergic rhinitis or non-allergic rhinitis. They work by reducing inflammation in the nasal passages, relieving congestion, and improving other symptoms such as itching, sneezing, and runny nose.

Leukotriene modifiers, decongestants, and antihistamines can also be used to manage nasal congestion, but they are generally considered second-line options or adjunct therapies.

Decongestants provide temporary relief by constricting blood vessels in the nasal passages, while antihistamines help with symptoms related to allergies. Leukotriene modifiers are primarily used for managing asthma and are not typically the first choice for nasal congestion alone.
