Para-Medical - P.M.E.C.E.
What the paper tests
P.M.E.C.E. is the JCECEB entrance route for paramedical diploma and certificate courses in Jharkhand, such as laboratory technician, radiology, operation-theatre technician, dialysis and optometry. It tests 10+2 science, English, basic hospital aptitude and safety awareness.
Core rules and concepts
- Biology: anatomy, physiology, microbiology, pathology and normal values.
- Chemistry: solutions, concentration, pH, disinfectants and laboratory safety.
- Physics: radiation safety, optics, electricity and measurement.
- Laboratory mathematics: dilution, percentage concentration, BMI and unit conversion.
- Aseptic technique: hand hygiene, sterile field, specimen handling and waste segregation.
Worked example
Prepare 500 mL of 0.9% saline from a 9% stock solution. Use (C_1V_1=C_2V_2): (9 \times V_1 = 0.9 \times 500), so (V_1 = 450/9 = 50) mL. Take 50 mL of stock and dilute to 500 mL. The reasoning: concentration and volume are inversely related during dilution; the amount of solute stays constant.
Traps that cost marks
- Confusing % w/v with % v/v.
- Using the final volume instead of the stock volume in the dilution formula.
- Ignoring ALARA and shielding in radiation-safety items.
- Reporting a normal range as a diagnosis.
- Breaking aseptic order: clean to dirty, or sterile field touched after contamination.
