What would the nurse include when creating a teaching plan that includes the long-term administration of phenytoin (Dilantin)?

Choice A reason: Tobacco use accelerates bone loss by reducing osteoblast activity and blood flow to bones, increasing osteoporosis risk. Cutting down on smoking improves bone density by enhancing bone formation and reducing resorption, a key preventive measure for women.
Choice B reason: Limiting alcohol to two drinks daily is not specific enough, as even moderate alcohol can impair calcium absorption and osteoblast function, increasing osteoporosis risk. Guidelines recommend minimal alcohol consumption, making this less accurate for prevention.
Choice C reason: Strengthening exercises (e.g., resistance training) stimulate osteoblast activity, increasing bone density and strength. This is critical for preventing osteoporosis, as mechanical stress on bones enhances mineralization, reducing fracture risk in women, especially postmenopausal.
Choice D reason: Calcium and vitamin D are essential for bone health. Calcium forms bone matrix, and vitamin D enhances its absorption. Adequate intake prevents bone resorption, maintaining bone density and reducing osteoporosis risk, making this a cornerstone of prevention.
Choice E reason: Weight-bearing exercises like walking stimulate bone formation by applying mechanical stress, increasing osteoblast activity. Walking 30 minutes three times weekly improves bone density and reduces fracture risk, making it an effective strategy for osteoporosis prevention in women.

Choice A reason: Drinking 2 liters of water daily supports general health but is not specific to phenytoin therapy. It does not prevent complications like gingival hyperplasia or hepatotoxicity, which are more directly related to phenytoin’s pharmacological effects and monitoring needs.
Choice B reason: Phenytoin does not eliminate seizure auras, which are sensory warnings due to focal cortical activity. It stabilizes neuronal membranes via sodium channel blockade, reducing seizure frequency but not preventing prodromal symptoms like auras.
Choice C reason: Not driving is appropriate, as phenytoin can cause dizziness or ataxia, impairing motor coordination. However, this is a safety precaution, not the most comprehensive indicator of understanding the need for long-term adherence to prevent seizure recurrence.
Choice D reason: Continuing phenytoin even after seizures stop is critical, as abrupt cessation can cause rebound seizures due to unopposed neuronal excitability. This reflects understanding of lifelong therapy needs for status epilepticus to maintain seizure control and prevent recurrence.
