Who we are

The Nurse, The Maths, and The Medication is an initiative of Nrs. David Ogunlabi, a Critical Care Nurse passionate about knowledge and impact.

David is the author of “The Nurse, The Math, and The Medication“, a comprehensive handbook for dosage calculations.

This book has been widely recognized and appreciated by the medical, nursing, and health community, prompting David and his team to take their vision and work to the next level by establishing this website.

David Ogunlabi also convenes the yearly national competition – NDDCCN (National Drug Dosage Calculation Competition for Nurses) which is an innovative, educational, and social platform for nurses focusing primarily on improving patient safety and preventing medication errors.

NDDCCN’s aim is to build a community of nurses who deeply understand and appreciate the importance of precise and accurate dosage calculations.

Ensuring patient safety is crucial in healthcare, and medication errors are a prominent concern. It is essential to take all necessary precautions to prevent mishaps and provide patients with the best care.

This platform is a valuable resource for nurses who strive to excel in their profession and positively impact patient outcomes.

Our Objective

Our primary objective is to highlight the crucial importance of accurate drug dosage calculations and provide additional academic and professional development resources to healthcare professionals.
