- A 1500 mL bag of 0.9% NaCl needs to have 9 grams of vancomycin added. How much water should the vancomycin be dissolved in prior to addition to ensure the resulting solution is isotonic with plasma? (SCE 0.06)arrow_forwardThe glass electrode used in commercial pH meters gives an electrical response proportional to the concentration of hydrogen ion. To convert these responses to a pH reading, the electrode must be calibrated against standard solutions of known H+ concentration. Determine the weight in grams of sodium dihydrogen phosphate (NaH2PO4 · H2O; FW 138) and disodium hydrogen phosphate (Na2HPO4 ; FW 142) needed to prepare 1 L of a standard buffer at pH 7.00 with a total phosphate concentration of 0.100 M . See Problem 24 for the pKa values of phosphoric acid.arrow_forwardIf a protein concentration is 1 mg/ml and diluted it by 1/10;what is the final concentration?arrow_forward
- A 78-year-old lady receiving treatment for hypertension was investigated by her doctor by monitoring renal function tests (reference ranges are given in brackets): 142 mmol/L 2.2 mmol/L Sodium Potassium Urea Creatinine Comment on these results. 8.9 mmol/L 142 μmol/L (135-145) (3.5-5.0) (3.5-6.6) (70-150)arrow_forwardNormal arterial pH is 7.35 to 7. 45. Both metabolic and respiratory alkalosis have pH more basic compare to the normal arterial pH. The difference is 0.5 units. What is pH value in alkalosis? Niemann-Pick type C disease is a progressive neurological disease; symptoms include unsteady walking with uncoordinated limb movements, slurred speech, a difficulty in swallowing, epilepsy and tremor. This condition is due to the abnormal functioning of a lysosome. State the normal functions performed by this organelle.arrow_forwardMake a list of the five most critical qualities of an effective extraction buffer. Please provide a brief description of each.arrow_forward
- A 2-year-old child presents with metabolic acidosis after ingesting an unknown number of flavored aspirin tablets. At presentation, her blood pH was 7.0. Given that the pKa of aspirin (salicylic acid) is 3, calculate the ratio of its ionized to un-ionized forms at pH 7.0.arrow_forwardThe pHpH scale for acidity is defined by pH=−log10[H+] where [H+]is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pH of 10.2. Calculate the concentration of hydrogen ions in moles per liter (M).arrow_forwardIf a patient collects a 24 hour urine specimen with a volume of 1500 mL, and the patient's serum Creatinine is 5 mg/dl, and the urine creatinine is 100 mg/dl, then what is the creatinine clearance in ml/min?arrow_forward
- The following data was obtained from an arterial blood sample drawn from a hospital patient. pH= 7.55 (7.35-7.45) PaCO2=25mmHg (33-45mmHg) HCO3-= 22.5mEq/L (22-28mEq/L The patient’s arterial findings are consistent with a diagnosis of which of the following? metabolic acidosis respiratory alkalosis metabolic alkalosis mixed acidosis respiratory acidosisarrow_forwardExplain thoroughly the Buffering Action of following Biological or Physiological Buffers:(a) Phosphate Buffer System.(b) Bicarbonate Buffer system.arrow_forwardA uremic patient has a urine output of 1.8 L/24 h and an average creatinine concentration of 2.2 mg/dL. What is the creatinine clearance? How would you adjust the dose of a drug normally given at 20 mg/kg every 6 hours in this patient (assume the urine creatinine concentration is 0.1 mg/mL and creatinine clearance is 100 mL/min)?arrow_forward
