A nurse is reinforcing teaching with a client who is newly diagnosed with myasthenia gravis and is to start taking neostigmine.Which of the following instructions should the nurse include in the teaching?.

Choice A rationale:Treating nasal rhinitis with an over-the-counter antihistamine is not directly related to neostigmine use or myasthenia gravis.Choice B rationale:If a medication dose is missed, wait until the next scheduled dose to take the medication is not the best advice. Neostigmine should be taken at regular intervals for maximum effectiveness.Choice C rationale:Expecting diaphoresis as a side effect of the neostigmine is not accurate. Diaphoresis is not a common side effect of neostigmine.Choice D rationale:Taking the medication 45 minutes before eating is correct. This timing helps maximize the medication’s effectiveness during meals, when muscle strength for swallowing is crucial.So, the correct answer is,D.
