What is an important consideration for a nurse when administering pain medications?

A. An empty bladder is not generally necessary when administering pain medications unless specific procedures or medications require it. B. While blood pressure monitoring may be important for certain medications (e.g., opioids that can cause hypotension), it is not a universal first consideration for all pain medications. C. Assessing for allergies is a critical safety step before administering any medication, including analgesics, to prevent adverse or life-threatening allergic reactions. D. Fasting is not required for most pain medications; many can be taken with or without food, although some may need food to reduce gastrointestinal irritation.
