A nurse cares for a client who presents with an acute exacerbation of multiple sclerosis (MS). Which prescribed medication should the nurse prepare to administer?

Choice A reason: A visibly shorter leg and extreme pain post-hip arthroplasty suggest possible hip dislocation, a serious complication. Assessing neurovascular status (pulse, sensation, movement, color, temperature) in both legs is critical to detect compromised blood flow or nerve damage, which could lead to tissue ischemia or permanent injury if not addressed promptly.
Choice B reason: Elevating the leg and applying ice may reduce swelling but does not address the potential dislocation indicated by leg shortening and pain. These interventions could delay critical assessment and management of neurovascular compromise, potentially worsening outcomes in a suspected dislocation scenario.
Choice C reason: Administering pain medication may alleviate discomfort but does not address the underlying cause, such as a dislocated hip prosthesis. Pain relief is secondary to ensuring neurovascular integrity and confirming the surgical leg’s alignment, which are critical to prevent complications like tissue necrosis.
Choice D reason: Attempting to place the leg in abduction without confirming the cause of shortening and pain risks further damage, especially if the hip is dislocated. Manipulation could exacerbate neurovascular compromise or prosthesis misalignment, leading to prolonged recovery or additional surgical intervention.

Choice A reason: Stopping antibiotics when symptoms resolve risks incomplete bacterial eradication, leading to recurrent or resistant otitis media. Antibiotics must be taken for the full course to ensure all pathogens (e.g., Streptococcus pneumoniae) are eliminated, preventing chronic infection or complications.
Choice B reason: Sharing antibiotics with siblings is dangerous, as it may lead to incorrect dosing, inappropriate treatment, or antibiotic resistance. Each child requires a specific prescription based on their condition, weight, and bacterial susceptibility, making this an unsafe practice.
Choice C reason: Giving antibiotics with milk may reduce absorption for some drugs (e.g., amoxicillin), as calcium can bind to certain antibiotics, decreasing bioavailability. This statement indicates a misunderstanding, as water is typically recommended to ensure optimal drug absorption.
Choice D reason: Administering the full course of antibiotics ensures complete eradication of bacteria causing otitis media, preventing recurrence or resistance. This reflects proper understanding, as completing the prescribed regimen targets pathogens like Haemophilus influenzae, ensuring effective treatment and reducing complication risks.
