A nurse is reviewing the medical record of a client who has a new prescription for selegiline transdermal. Which of the following findings should the nurse identify as a contraindication for administration of this medication to the client?

Choice A reason: Gastric reflux is not a contraindication for selegiline, a monoamine oxidase inhibitor (MAOI). While gastrointestinal side effects may occur, reflux does not interact with selegiline’s mechanism, which inhibits monoamine breakdown, affecting neurotransmitters like dopamine, not digestive processes. Choice B reason: Drinking orange juice is safe with selegiline transdermal, as it avoids significant tyramine interactions seen with oral MAOIs. Tyramine in foods can cause hypertensive crises, but juice lacks high tyramine, making this an acceptable dietary choice for clients. Choice C reason: St. John’s wort, a herbal supplement, is contraindicated with selegiline, as it increases serotonin levels, risking serotonin syndrome when combined with MAOIs. This life-threatening condition involves autonomic instability and neuromuscular symptoms, necessitating avoidance to ensure safe antidepressant therapy. Choice D reason: Cholelithiasis (gallstones) is not a contraindication for selegiline. MAOIs primarily affect neurotransmitter metabolism, not biliary function. While gallstones require dietary or surgical management, they do not interact with selegiline’s pharmacological profile, making this condition irrelevant to its administration.
