The nurse is preparing to apply the client’s scheduled fentanyl transdermal patch. The nurse notes the previously applied patch is intact on the client’s upper back and the client reports no pain. Which action should the nurse take?

1. Recommend use of an over-the-counter antipyretic: While treating fever with an antipyretic like acetaminophen or ibuprofen may provide symptomatic relief, the priority in this scenario is to assess for other adverse effects of the medication. Fever can be a sign of an allergic reaction or other adverse effects to the antibiotic. Therefore, it is important to first assess for other symptoms before recommending symptomatic treatment.

B) Determine if other adverse effects have developed: This is the correct answer. The onset of a low-grade fever after starting a new medication, such as amoxicillin, warrants further assessment for other adverse effects. The nurse should inquire about other symptoms the client may be experiencing, such as rash, itching, swelling, difficulty breathing, or gastrointestinal disturbances, which could indicate an allergic reaction or other adverse effects.

C) Ask if the medication has been kept refrigerated: While it is important to ensure proper storage of medications, such as amoxicillin, which may require refrigeration, the onset of a low-grade fever is not typically related to medication storage. Therefore, this action would not address the client’s current symptoms and concerns.

D) Instruct the client to increase oral fluid intake: While maintaining adequate hydration is important for overall health and may help manage symptoms of illness, such as fever, the priority in this scenario is to assess for other adverse effects of the medication. Therefore, increasing oral fluid intake alone would not address the potential adverse effects of amoxicillin.

A) Irritable bowel syndrome: While it's im’ortant to consider the client's me’ical history comprehensively, sumatriptan succinate is primarily contraindicated in clients with a history of coronary artery disease due to its potential vasoconstrictive effects.

B) Coronary artery disease: This is the correct response. Sumatriptan succinate is contraindicated in clients with a history of coronary artery disease or ischemic heart disease due to its potential to cause coronary vasospasm and increase the risk of myocardial ischemia or infarction.

C) Type 2 diabetes mellitus: While it's im’ortant to consider the client's ov’rall medical history, type 2 diabetes mellitus is not specifically contraindicated with sumatriptan succinate use.

D) Seasonal allergic rhinitis: While seasonal allergic rhinitis is relevant to the client's me’ical history, it is not directly related to the contraindications of sumatriptan succinate.

Therefore, the most crucial consideration before administering sumatriptan succinate is to determine if the client has a history of coronary artery disease or ischemic heart disease to avoid potential adverse cardiac effects.
