The nurse learns that a patient will receive an infusion of Propofol for a procedure. The nurse knows that the following will increase risk for adverse effects with this infusion:

Choice A rationale: NSAIDs, including ketorolac, can affect renal function and may require dose adjustment in patients with impaired renal function.
Choice B rationale: Apical pulse is not typically assessed before administering ketorolac.
Choice C rationale: Serum potassium is not directly affected by ketorolac.
Choice D rationale: Ketorolac is associated with an increased risk of bleeding, so assessing the patient's bleeding risk is important.
Choice E rationale: Ketorolac is contraindicated in pregnant women, especially in the third trimester, due to the risk of premature closure of the ductus arteriosus in the fetus.

Choice A rationale: Methylphenidate is a central nervous system stimulant, and excessive caffeine intake can exacerbate its stimulant effects. Consuming an unlimited number of cola soft drinks, which typically contain caffeine, is not advisable. The patient should be educated to moderate caffeine intake to avoid potential interactions and side effects.
Choice B rationale: Methylphenidate can interact with caffeine, so avoiding chocolate, coffee, and tea is a valid recommendation to prevent excessive stimulant effects.
Choice C rationale: Decaffeinated coffee still contains a small amount of caffeine, and patients taking methylphenidate should be aware of this to manage their overall caffeine intake.
Choice D rationale: Taking methylphenidate after breakfast is a common recommendation to minimize appetite suppression and potential weight loss associated with the medication.
