Acid buffering - Study guides, Class notes & Summaries

Normal acid base values pH: pCO2: HCO3: PaO2: Correct Answer-pH: 7.35 - 7.45 pCO2: 35-45 / respiratory HCO3: 22-26 / metabolic PaO2: 80-100 What happens to hydrogen ions and bicarbonate in acidosis? Correct Answer-Hydrogen ions increase because of the increase in CO2 (CO2 is an acid) or decrease in bicarb. What happens to hydrogens ions and HCO3 in alkalosis? Correct Answer-reduction of hydrogen ions as evidenced by a decrease in the pCO2 or increase in the HCO3. How will the b...

Purpose of the pituitary gland - hormones help regulate other glands in the endocrine system produces ADH and oxytocin Respiratory regulation of alkalosis - decreased H+ in blood triggers brain to decrease rate and depth of breathing-retains CO2 At risk populations for acid-base imbalances - Diabetes, COPD, Renal failure, severe vomiting/diarrhea Respiratory acidosis lab values - pH < 7.35, CO2 > 45 mmHg Metabolic acidosis lab values - pH < 7.35, HCO3 < 22 mEq/L Respiratory a...

Fluid & Electrolyte Needs - - Homeostasis - Affected by digestion, absorption, metabolism of nutrients and excretion of waste Functions of Body Fluids - - Need 1.5 L - 2.5L per day - 60-70% body weight is fluid [70% intracellular, 30% extracellular] - Transport nutrients and wastes to and from cells - Maintain body temp., acid-base balance, aids in digestion and elimination Assessment of Fluid Balance - - Health history [age, acute illness, environmental factors, diet, medications] - ...

WGU D236 PATHOPHYSIOLOGY FINAL EXAM-with 100% verified solutions-2024/2025 updated What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? - ANSWERS Starling's Law describes how fluids move across the capillary membrane. There are two major opposing forces that act to balance each other, hydrostatic pressure (pushing water out of the capillaries) and osmotic pressure (including oncontic pressure, which pushes fluid int...

What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? - ANSWER Starling's Law describes how fluids move across the capillary membrane. There are two major opposing forces that act to balance each other, hydrostatic pressure (pushing water out of the capillaries) and osmotic pressure (including oncontic pressure, which pushes fluid into the capillaries). Both electrolytes and proteins (oncontic pressure) in the blood affe...

What are the different buffer systems? - Answer- Carbonic acid-bicarbonate buffer Respiratory buffer kidney buffer. How long does the Carbonic acid-bicarbonate buffer system take place? - Answer- Second to second. How long does the respiratory buffer system take place? - Answer- Minute to minute How long does the kidney buffer system take place? - Answer- Hours to days where does the carbonic acid buffering system opperate? - Answer- In the blood, lungs, and kidneys What is the ...

Three processes of Acid Base Balance correct answers 1. Acid production 2. Acid Buffering 3. Acid excretion Three mechanisms for A/B regulation correct answers 1. Buffers (secs) 2. Respiratory (few mins) 3. Renal (few hours) acid base equation correct answers CO2 + H2O <-> H2CO3 <-> H+ + HCO3- - CO2 is lungs - HCO3 is kidneys Buffers too much acid correct answers bicarbonate will take up hydrogen ions and become carbonic acid to break released as CO2 in the lungs H...
