A nurse is teaching a client who has a seizure disorder and has a new prescription for phenytoin.
Which of the following client statements indicates an understanding of the teaching?

Choice A rationale

Peripheral edema occurs due to the vasodilatory effects of verapamil, leading to fluid accumulation in the extremities, which is a common adverse effect of calcium channel blockers.

Choice B rationale

Verapamil, a calcium channel blocker, can slow the heart rate by inhibiting calcium influx in cardiac cells, potentially leading to bradycardia in some patients.

Choice C rationale

Constipation is a known adverse effect of verapamil, caused by the medication's relaxation of smooth muscles in the gastrointestinal tract, leading to decreased bowel motility.

Choice D rationale

Blurred vision is not a common adverse effect of verapamil and might indicate a different underlying condition or medication side effect requiring further evaluation.

Choice E rationale

Insomnia is not typically associated with verapamil use and may be attributed to other factors or conditions the patient is experiencing rather than the medication itself.

Choice A rationale

While a CBC is important for overall health assessment, it is not directly related to raloxifene initiation. Raloxifene primarily affects bone density and estrogen receptors, not blood cell counts.

Choice B rationale

Family history of colon cancer is important but not directly related to raloxifene use. Raloxifene is used to treat osteoporosis and reduce the risk of invasive breast cancer, not colon cancer.

Choice C rationale

Thyroid function assessment is important for overall health but is not directly related to raloxifene therapy. Raloxifene affects estrogen receptors and bone density, not thyroid function.

Choice D rationale

Raloxifene is contraindicated in pregnancy due to potential harm to the fetus. Assessing pregnancy status ensures the safety and appropriateness of raloxifene therapy in women of childbearing age. .
