1 Department of Interdisciplinary Studies IDST 1400 Medical Mathematics Revised 2015 by: Marilyn Donahue Course Description This course will provide a review of basic mathematical calculations and will instruct the learner on how to convert equivalents from one system to another and accurately mix and measure drugs. Emphasis will be placed on how these techniques are used in the administration of medications for patient use. Credits/Modes of Instruction This is 3 credit course (~50 hours) that relies on hands-on activities, assignments, and discussion. Should the instructor feel that a class meeting(s) is necessary, she/he will notify all student(s) via or telephone of the class meeting time and location. The course instructor will organize the class in coordination with Rutgers School of Heath Related Professions syllabus, and communicate requirements with student, either by or telephone. Pre/Co requisites All math remediation and successful high school completion of Dynamics of Health Care in Society Instructor The instructor will be a Rutgers SHRP faculty (or adjunct) member. Course Goals The goals of this course is to provide a review of basic mathematical calculations, to instruct the learner on how to convert equivalents from one system to another and accurately mix and measure drugs, to provide the learner with the necessary mathematical background needed for pharmacology, and to provide the learner with the theory and skills necessary to administer medication safely. For the purpose of sharpening the learners math calculation skills and to develop a logical sequence of operations in solving complex dosage calculations, No calculators are used during this course 1

3 Requirements for Completion Attendance is required, as well as completion of all activities and assignments. Students will be required to arrange with preceptor a make-up date in case of an absence. Assignments are expected to be submitted on their due date to the course preceptor. Late assignments will be marked down 1 point per day late. Requirements Weight Attendance/Participation/Group Discussion 10% Chapter Assignments/Classwork 10% Chapter Quizzes 15% Course Projects Humanitarian Aid Campaign Design & Research Virtual Medication Administration 25% Unit Tests and Final Examination 40% Total 100% Evaluation and Grading Grade Determination The minimum level of satisfactory performance in this course is a C or better. To receive a C or better, students must first complete ALL course requirements specified above, including meeting the minimum attendance expectation. Based on the evaluations methods and criteria previously described, each requirement is then scored on a point scale. The final letter grade is based on the weighted average of all requirements. Upon successful completion of the course students will be eligible to take the Health Science Careers standardized exam to determine college credit. All students must attain a C (74) or better to earn college credits. Minimum passing standardized exam grade for all students must be at least 70 before calculations of college transcript grade can be determined. The Rutgers grade listed on the student s transcript will be comprised of 50% of the Rutgers-SHRP standardized exam grade and 50% of the high school course grade. 3

Honor Code and Academic Integrity (Refer to your SHRP Student Handbook at The faculty of Rutgers School of Health Related Professions believes that students must observe and support high standards of honesty and integrity. For this reason, all students in this course are expected to abide by the School's Honor Code and uphold its Code of Academic Integrity. As described in detail in your Student Handbook, violations of the Code of Academic Integrity include cheating, plagiarism, fabrication and/or academic misconduct. All such violations will be considered with gravest concern and may be punishable with sanctions as severe as suspension or dismissal. If you have not previously affirmed the School's Honor Code (either in writing or electronically), you must submit a signed and dated copy of the Honor Code to the instructor by the end of the first week of the semester. The Honor Code form is provided in the current SHRP Student Handbook. 4

Virtual Clinical Excursion Software Complete all shifts and receive virtual preceptor s report for each shift. Practice makes perfect, do the shift over until its error free. For the Final Project Grade o Students must select all patients at the beginning of a shift and complete the shift caring for all patients in the same shift session o Screen shots of the virtual preceptor s reports for each patient on each shift to be sent to the course instructor. o Preceptor s report will show a completion times for each patient. These must match, proving the virtual patients were all cared for during the same session.
