About rnref

rnref.com is a free, fast-loading clinical reference built for registered nurses, licensed practical nurses, and nursing students who need quick access to vital signs, lab values, drug calculations, assessment tools, and clinical protocols at the bedside or during study.

Our Purpose

We organize commonly used nursing reference material into clear, searchable pages so you can find normal ranges, formulas, and protocols without wading through slow apps or PDFs. rnref is an educational quick-reference tool — not a substitute for your clinical judgment, preceptor, or facility policy.

Who We Are

rnref is maintained by a small team with a background in nursing and healthcare software. We focus on accuracy, readability, and fast page loads because reference tools only help when they are trustworthy and available when you need them.

Editorial Standards

Content is compiled and reviewed against widely used nursing references and evidence-based clinical guidelines. We prioritize:

• Accuracy of reference ranges, formulas, and protocols
• Clear labeling when values vary by age, setting, or institution
• Prominent medical disclaimers on every reference page
• Regular review when guidelines or standards change

Reference material may draw on sources such as the CDC isolation guidelines, American Heart Association resuscitation guidelines, and NIH/MedlinePlus clinical references. Each topic page includes a References section with direct links to the public sources used. Always verify against your institution’s current protocols.
