What mathematical concepts should you be familiar with for the NEX?

For the Nursing Entrance Exam (NEX), it is essential to have a solid understanding of basic arithmetic, fractions, decimals, percentages, and drug dosage calculations. This foundation is crucial in the nursing field because daily tasks often involve calculations related to medication dosages, IV flow rates, and nutrition needs.

Proficiency in basic arithmetic allows nurses to accurately perform computations necessary for patient care, while understanding fractions, decimals, and percentages is vital when converting measurements or determining the right dosages based on patient weight or conditions. Drug dosage calculations, in particular, are a critical aspect of nursing practice, as incorrect dosages can lead to serious patient safety issues.

The other mathematical concepts listed, such as complex algebra, calculus, trigonometry, geometry, and number theory, may not be directly applicable in most nursing practice settings. Instead, a firm grasp of the basic math skills outlined in the correct choice ensures that nursing students are well-prepared for the calculations they will encounter in their careers.
