A nurse in a long-term care facility is assessing an older adult client for depression. Which of the following findings should the nurse expect?

A. Withholding a prescribed medication that is causing adverse effects for the client
The principle of nonmaleficence, often summarized as "do no harm," emphasizes the nurse's duty to prevent harm and to remove existing harm. If a medication prescribed to a client is causing adverse effects, the nurse should withhold the medication to prevent harm to the client.

B. Educating the client about legal rights concerning treatment
Educating the client about their legal rights falls under providing information and ensuring the client's autonomy but does not directly address the principle of non-maleficence.

C. Providing the client with quality care regardless of ability to pay for treatment
Providing quality care regardless of the client's ability to pay is an ethical practice, but it aligns more with the principles of justice and beneficence rather than nonmaleficence.

D. Being truthful with the client about the manifestations of withdrawal
Being truthful and providing accurate information to the client about withdrawal symptoms is crucial, but it doesn't directly address the principle of nonmaleficence.

A. Magnesium hydroxide:
Magnesium hydroxide is an antacid commonly used to relieve indigestion and heartburn. It does not have any known significant interactions with tranylcypromine. MAOIs typically do not interfere with antacids.

B. Ibuprofen:
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain and inflammation. It does not have specific interactions with tranylcypromine. However, individuals taking MAOIs should be cautious about using NSAIDs due to the potential risk of bleeding, especially gastrointestinal bleeding. While it's not a direct interaction, it's generally advisable for individuals taking MAOIs to consult their healthcare provider before using NSAIDs.

C. Ranitidine:
Ranitidine is an H2 blocker used to reduce stomach acid production. It does not have any known significant interactions with tranylcypromine. H2 blockers like ranitidine are often used to manage gastrointestinal issues and are generally considered safe when taken with MAOIs.

D. Pseudoephedrine:
Pseudoephedrine is a decongestant commonly found in cold and allergy medications. It can cause a dangerous increase in blood pressure when combined with MAOIs, potentially leading to a hypertensive crisis. Due to this serious interaction, individuals taking MAOIs are strongly advised to avoid medications containing pseudoephedrine.
