During the NR446, you are required demonstrate medication calculation proficiency by passing the math exam with a 95% on day one (1) of class. To prepare for the math exam, please read through the NR446 medication calc policy and complete the attached NR446 Math packet. The packet is intended as supplemental practice in addition to the practice questions on Canvas. You are also required to complete the practice medication calculations problems located under module one on canvas as well as this math packet before any math exam attempt. You are encouraged to seek assistance from the Student Learning Center (SLC) or your designated course instructor if you experience any difficulty completing the math practice packet.
