NCM 118: CARE OF CLIENTS WITH LIFE-THREATHENING CONDITIONS, ACUTELY ILL/MULTI-ORGAN PROBLEMS HIGH ACUITY AND EMERGENCY SITUATION Attendance is mandatory and checked within the first 15 minutes of the designated class schedule. A student with accumulated 3 absences of the total class meetings will be dropped from the roll. Maximum participation is expected in all classroom activities. At all instances, respect for classmates and instructors are expected. Observe proper decorum. Come in complete uniform. Use of cellphones, tablets and other gadgets for social and other purposes not related to the learning material are strictly prohibited during class. It is expected that all written outputs are submitted on time on the designated dates.
