Question

Part 1

Complete the following problems using the Tic-Tac-Toe method of ABG interpretation (each worth 1 point)

	ABG		Acid/Base Status	List One Possible Causative Clinical Condition
Ex:	pH	7.29	Metabolic acidosis	Renal failure
	pCO2	37
	HCO3	19
1	pH	7.58
	pCO2	45
	HCO3	32
2	pH	7.22
	pCO2	58
	HCO3	26
3	pH	7.38
	pCO2	38
	HCO3	24
4	pH	7.19
	pCO2	34
	HCO3	18

Answer 1

No1. pH is in alkaline state i.e 7.58 it is caused by HcO3(32) and Pco2 is in the normal range 45

So, it is metabolic alkalosis

There is verity of cause for metabolic alkalosis 1. Recurrent vomiting 2. NG tube aspiration 3. Diuretic use

No2. pH is in Acidic state i.e 7.22 it is due to PCO2 i.e 58 and Hco3 is in the normal range I.e 26

It is Respiratory Acidosis

Possible cause of Respiratory Acidosis is 1. Severe Asthma 2.COPD 3.Airway obstruction 3.Cardiac arrest 4. The disease of respiratory muscles

No3. pH, PCo2, and HCo3, all 3 are in the normal range so, it is a balanced state.

No4.pH is in acidic state i.e 7.19 it is due to Hco3(18) and PCo2 in Normal range

It is Metabolic Acidosis

It may be Due to Ketoacidosis, Lactic acidosis or by Kidney disease
