After determining that the patient has a tension-type headache, which patient statement supports the nurse's finding?

A. L1-2. Clients with a lumbar spinal cord injury at L1-L2 may have partial function of the lower extremities, allowing for ambulation with long leg braces and assistive devices. This level of injury typically spares some hip flexor and knee extensor function, enabling limited walking with support.
B. T6-7. A thoracic spinal cord injury at T6-T7 results in paralysis of the lower extremities (paraplegia), making independent ambulation unlikely. Clients with mid-thoracic injuries require a wheelchair for mobility, though some may use braces for short-distance standing or walking with extensive support.
C. C7-8. A cervical spinal cord injury at C7-C8 leads to quadriplegia with partial upper limb function but no voluntary lower extremity movement. These clients rely on wheelchairs for mobility and cannot ambulate with braces.
D. T1-2. A T1-T2 injury results in complete lower extremity paralysis, preventing functional ambulation. Clients at this level typically use manual wheelchairs for mobility and retain full arm and hand function for self-care and wheelchair propulsion.

A. "I know that I cannot switch brands of this medication." Phenytoin has a narrow therapeutic index, meaning small changes in drug levels can lead to toxicity or treatment failure. Different brands and formulations may have variations in absorption, so clients should stay on the same brand unless directed otherwise by their provider.
B. "I'll be glad when I can stop taking this medicine." Phenytoin is a long-term medication for seizure control and should not be stopped abruptly, as this can lead to recurrent seizures or status epilepticus. Most clients with epilepsy require lifelong therapy, making this statement incorrect and indicating a need for further teaching.
C. "I have made an appointment to see my dentist next week." Phenytoin can cause gingival hyperplasia (gum overgrowth), a common side effect that can be minimized with good oral hygiene and regular dental visits. This statement indicates that the client understands the importance of dental care while taking phenytoin.
D. "I will notify my doctor before taking any other medications." Phenytoin has many drug interactions because it induces liver enzymes, affecting the metabolism of other medications. Clients should always consult their provider before taking new prescriptions, over-the-counter drugs, or supplements to avoid interactions that could alter drug effectiveness or increase toxicity risk.
