Prophylaxis
A preventive measure, medication, or intervention given to reduce the risk of disease, complication, or recurrence.
The exam tests prophylaxis as a timing and “before-the-fact” question: the tell is a stem where the client has no current problem, so the correct answer is the action that prevents one. Surgical antibiotic prophylaxis is the classic — the keystone fact is to infuse the antibiotic within 60 minutes before incision (the window extends to 120 minutes for vancomycin or a fluoroquinolone because of their longer infusion time). Watch for SATA items separating preventive from treatment actions, plus contraindication traps: heparin-based prophylaxis is held when the platelet count falls ~50%, signaling HIT (typically days 5–14), and SCDs are avoided with active DVT or limb ischemia.
The classic trap is confusing prophylaxis with its related terms. Prophylaxis acts before any problem; an intervention treats an identified problem already present; monitoring only watches for one; a complication is the bad outcome prophylaxis aims to avert. Hook: prophylaxis is the “pro” defense — you stop the goal before it happens, while intervention plays catch-up after the shot is taken.
