In this brief instructional video, the presenter stresses a critical NCLEX pharmacology point: nurses must obtain appropriate cultures (e.g., blood cultures) before initiating anti‑infective therapy. By collecting cultures first, clinicians can accurately identify the causative bacteria, fungi, or virus, ensuring targeted treatment and avoiding loss of diagnostic information once the anti‑infective is administered. The speaker also plugs the Pharmacology Study system available in the Nursing SOS shop as a resource for students struggling with pharmacology.

Here's a key point to know for anti infectives for the NCLEX in your nursing school exams. The NCLEX loves to test you on this. You must must must take cultures. So take blood cultures and check for whatever bacteria or fungi or virus or whatever is causing the infection before we start treatment. We want to take cultures before starting treatment because that way we're going to get the most accurate sample possible and hopefully figure out what causing the problem for the patient before we go and kill whatever it is with the anti infective. So we want to make sure that you're taking cultures before we start treatment with the anti infective medication. If you're struggling with pharmacology in nursing school, be sure to check out the Pharmacology Study system inside the nursing SOS shop.
