Final answer:
When administering imatinib, nurses should monitor for signs of allergic reactions, as an allergic response to the drug could occur. Other considerations include liver function monitoring, but an immediate discontinuation of the medication due to side effects is not advised without a proper assessment.
Step-by-step explanation:
A nursing consideration for patients receiving imatinib would be to monitor for signs of allergic reactions. It is important to observe patients for any hypersensitivity due to the potential of drug allergy. Administering imatinib requires other considerations as well, like ensuring liver function tests are conducted, as liver toxicity can occur, but the specific answer to the question is focusing on allergic reactions. Monitoring is preferable to discontinuing the medication immediately if side effects occur, as some side effects may be manageable or expected. It's also not necessary to obtain a baseline echocardiogram unless there is a specific clinical indication, and while imatinib can be taken with or without food, administering it with a meal may reduce gastrointestinal upset.
