A nurse is caring for a client who reports he has headaches after taking chewable isosorbide dinitrate. Which of the following statements should the nurse make?

Choice A reason: Swallowing isn’t an option for chewable isosorbide; it’s designed for sublingual absorption. This advice is incorrect and won’t address vasodilatory headache effects.Choice B reason: Discontinuing isosorbide risks angina exacerbation in cardiac patients. Headaches are tolerable side effects, so stopping isn’t advised without provider input.Choice C reason: Empty stomach intake doesn’t reduce isosorbide’s vasodilatory headaches. Timing doesn’t alter its nitrate-induced vessel dilation, making this ineffective advice.Choice D reason: Headaches from isosorbide’s vasodilation typically subside with tolerance over time. This reassures the client, aligning with expected nitrate therapy adaptation.
