Final answer:
The correct values to complete the provided ranges for arterial blood gases are Bicarb (HCO3-): 22-28 and PACO2: 35-45 (for females) or 35-48 (for males).
Step-by-step explanation:
The student's question pertains to normal arterial blood gas values which are crucial for determining a patient's acid-base balance.
The reference values given for blood gases include: pH: 7.35-7.45; the partial pressure of carbon dioxide (pCO2): 35-45 mm Hg for females and 35-48 mm Hg for males; and the total venous bicarbonate (HCO3-): 22-29 mM.
Therefore, when completing the provided ranges, the correct values would be Bicarb (HCO3-): 22-28 and PACO2: 35-45 for females (or 35-48 for males).
Understanding these ranges is critical as deviations can indicate conditions such as acidosis or alkalosis.
The bicarbonate serves as an important buffer in the blood's buffer system, adapting to metabolic by-products and helping to maintain the blood pH within its narrow, vital range.
