NRSG 331 Acid Base Balance - Pathophysiology 2 Questions With Complete Solutions

pH normal level correct answer: 7.35-7.45 pCO2 normal level correct answer: 35-45 HCO3 normal level correct answer: 22-28 Think of ________ as an acid. correct answer: pCO2 Think of ________ as a base; similar to pH trends. correct answer: HCO3 Decreased pH of arterial blood (<7.35) -a systemic increase in H+ ion concentration or decrease in HCO3- correct answer: Acidosis Increased pH of arterial blood (>7.45) -a systemic decrease in H+ ion concentration or increase in HCO3- correct answer: Alkalosis With (initial) ______________ acidosis/alkalosis, HCO3 is normal. correct answer: Respiratory With (initial) ______________ acidosis/alkalosis, HCO3 is high or low. correct answer: Metabolic pH low = ___________ in H+ ion concentration. correct answer: increase pH high = ___________ in H+ ion concentration. correct answer: decrease In _______________ acidosis/alkalosis, pH and HCO3 initial ABGs are the same (low/low or high/high) correct answer: Metabolic What is the respiratory indicator? (high/low with respiratory acidosis/alkalosis, but normal with metabolic) correct answer: CO2 What is the metabolic indicator? (high/low with metabolic acidosis/alkalosis, but normal with respiratory) correct answer: HCO3 Initial ABGs pH: low
