Oral preparations VIII.Injectable preparations IX. Intravenous preparations Evaluation Methods: Final examination (80%) Passing of the final exam is prerequisite to progressing in the nursing sequence. Students must attain a grade of 85% or higher to pass the exam. Should a student not attain a grade of 85% or higher on the final examination, he/she will be given a second exam. Should a student not attain a grade of 85% or higher on the second exam, he/she will not progress in the nursing sequence. Once a student attains a grade of 85% of higher, attendance and homework assignments will be calculated into the final grade. Calculators will be provided for the final exam. The final exam will be administered during finals’ week. Date and time to be announced. Attendance: (10%) Assignments/homework: (10%): students must have completed homework assignments prior to class. Final grade configuration: Final exam (80%) during finals’ week Attendance: (10%) will be taken each time your section meets; total 7 classes/section Assignments/homework: (10%) assignments listed by weeks 1-7 in Bb; assignments are due the day you have your class scheduled (refer to dates/schedule of classes); no late assignments accepted Total: 100% The grading system of the Department of Nursing will be utilized.
