A nurse is planning postoperative care for a client following a total hip arthroplasty. What nursing interventions would help prevent venous thromboembolism for this client? (Select all that apply)

Choice A reason: Diazepam is effective for acute seizures but is less preferred for status epilepticus due to its shorter duration and risk of accumulation with repeated doses. It acts on GABA receptors but is less practical for sustained control in emergencies.
Choice B reason: Midazolam is the drug of choice for status epilepticus due to its rapid onset and short half-life, allowing quick seizure termination via GABA receptor enhancement. Its intramuscular or intranasal administration is practical in emergencies, ensuring prompt control of prolonged seizures.
Choice C reason: Valproic acid is used for long-term seizure management, not acute status epilepticus. Its slower onset and oral/IV administration are less effective for rapid seizure termination, as it modulates sodium channels and GABA but requires time to reach therapeutic levels.
Choice D reason: Carbamazepine is a long-term antiepileptic, not suitable for status epilepticus. It stabilizes sodium channels to prevent seizures but lacks the rapid onset needed for emergency treatment, making it inappropriate for acute, life-threatening seizure activity.

Choice A reason: Elevating the arm reduces edema but does not address a loose cast, which can fail to immobilize the fracture. Inadequate immobilization risks malunion or delayed healing, as the cast must maintain stable alignment of the fractured bones.
Choice B reason: Muscle atrophy occurs over weeks, not 3 days, and is not the primary cause of a loose cast. Initial swelling reduction post-fracture causes the looseness, requiring cast replacement to ensure proper immobilization and fracture stability.
Choice C reason: Wrapping a bandage around a loose cast is inadequate, as it does not provide the rigid support needed for fracture healing. Improper immobilization can lead to bone misalignment, delayed union, or soft tissue injury, necessitating a new cast.
Choice D reason: A loose cast 3 days post-application indicates reduced swelling, common after initial trauma. A new, properly fitted cast is needed to ensure immobilization, as loose casts fail to stabilize the fracture, risking malunion or nonunion of the wrist bones.
