- The pH of human blood is buffered at 7.35 to 7.45. If the [OH-] of the blood sample is 6.3x10-6, calculate its pH value. Is the patient’s pH within the range? Or is experiencing acidosis or alkalosis condition?During the treatment for COVID-19, one complication includes an increase of CO2 in the lungs. This buildup of CO2 can result in a serious condition called respiratory acidosis if the level of H+ significantly changes. If the pH drops by 1 unit, what has happened to the H+ concentration?The electrode of a pH meter is placed in a sample of urine, and a reading of 7.9 is obtained. Is the sample acidic,basic, or neutral? What is the concentration of H3O+ in the urine sample?
- Given the equation of the line, y=150x-8.1221 (cells per mL is in 10^8), what is the CFU per mL of the original suspension if the thousand-fold dilution of that suspension has an absorbance of 0.3 at 600nm? * A. 3.7 x 10^12 B. 3.7 x 10^9 C. 3.7 x 10^1 D. None of these is correctBased on the pH of your drug, if your drug was in a high concentration in the blood, how would it affect the pH of your blood. Would it cause acidosis or alkalosis, and how would you treat this? the drug name is captopril and the pH is 2.65What is the final concentration if 75 mL of a 3.5 M glucose solution is diluted to a volume of 450 mL?
- Metabolic alkalosis refers to a process whereupon decreased hydrogen ion, or increased bicarbonate, concentrations occur in the body, and the blood pH becomes too basic. Answer the following questions: How does the body regain its acid-base equilibria/balance? What happens when that balance does not happen? Will a buffer system still work under these conditions?Define the following:- pH- Buffer- pKaBicarbonate/carbonic acid buffer in blood is an example of an equilibrium reaction that is meant to be very insensitive to change. How does the bicarbonate/carbonic acid buffer re-establish equilibrium if acidity increases? How does the bicarbonate/carbonic acid buffer re-establish equilibrium if alkalinity increases?
- 1. A woman who had been vomiting for 3 days was taken to the emergency department at University of Chicago by her family. The following blood measurements were obtained: pH = 7.6; PCO2 = 48 mmHg; and HCO3- = 37 mEq/L. A) Name the acid-base disorder you suspect that she has? And explain why you have selected this acid- base disorder. B) Provide a physiologic explanation for Gastrointestinal, Respiratory, and Renal changes that are taking place to either cause or compensate for the acid-base disorder.What is a loading buffer and how does it function? What does 10x loading buffer mean?Example The reference range for blood pH is 7.35 – 7.42. What is this range expressed as [H+] in nmol l-1? Calculation: pH = - log [H+] 7.35 = - log [H+] [H+] = antilog -7.35 = 4.47 x 10-8 mol.l-1 = 44.7nmol.l-1 similarly: pH 7.42 = 38.0 nmol.l-1 Range [H+] = 38 – 44.7 nmol.l-1 If the blood pH decreases in an acidosis from 7.42 to 7.15, what is the change in [H+] in nmol.l-1? so this is example on the worksheet, but i still understand how to answer the question.
