Calculate the value of MCV,MCH and MCHC base on this result.

a) MCV (3 Mark)

b) MCH (3 Mark)

c) MCHC (3 Mark)

STATION 15

ANSWER

Haemoglobin (Hb) = 6.3 g/dlAmount of RBC = 1.88 X 1012/literPack cell volume = 0.19/L

MCV = PCV / RBC= (0.19 / 1.88 X 1012) l= (0.101 X 10-12) l= 101 fl (fl – unit SI)

MCH = Hb / RBC= (6.3 X 10 / 1.88 X 1012) g= (3.351 X 10-11) g= 33.51 pg (pg-unit SI)

MCHC = Hb / PCV= (6.3 / 0.19) g/dl= 33.15 g/dl (g/dl- unit SI)

Active StationWhat must you do?

• Greet the doctor.• Tell him/her your matric no.• Ask for permission from doctor to start your task.• Start your task:• Access danger.• Check consciousness of victim.• Ask for help.Do whatever you need to do. Remember ABC(A-airway, B-breathing, C-circulation)

•P/S: if the victim is at roadside, you need to move him to a safe place first before doing anything. (Of course you must access danger first!)

Scenario 1:

If the victim is unconscious & is bleeding at his thigh, what must you do first?

Do CPR first!!!

Patent the airway first (by head tilt chin lift postion).Check for carotid pulse & breathing. (If no pulse/breathing, do 2 mouth-to-mouth resusitation, followed by 30 chest compression)*Count out loud when you’re compressing chest!

When do you stop CPR? (Doctor most probably will ask this!)After 5 cycles of resusitation/you’re tired/ambulance or paramedics have arrived/victim recovers from unconsciousness.

Where to check for carotid pulse?2 cm lateral to thyroid prominence (Adam’s apple)For how long?10 seconds

Only then you try to stop the bleeding(bandage).

Good luck in your PRO 1!
