A patient was connected to an artificial ventilation device during a surgery on the gastrointestinal tract. 60 minutes after the start of the operation, a gas composition of the blood and pH were examined: - PaCO₂ = 26 mm Hg - pH = 7.5 Questions: 1. Give an opinion on the gas composition of blood and the acid-base state 2. What type of violation of external respiration is developed in the patient? 3. Give a definition of this type of respiratory pathology

A 50-year-old man came to the emergency department after returning from foreign travel. His symptoms included persistent diarrhea (over the past 3 days) and rapid respiration (tachypnea). Blood gases were drawn with the following results: pH 7.21 pco2 19 mm Hg po2 96 mm Hg HCO3 − 7 mmol/L SO2 96% (calculated) (reference range, >95%) Why is the HCO3 − level so low? Why does the patient have rapid respiration?
A patient has severe uncompensated respiratory acidosis. Temperature is normal and hemoglobin concentration is within the reference range. Which of the following oxygen dissociation curves best describes the relationship between oxygen content and PO2 (the solid curve is normal) in this patient?
Which of the following statements is true for Bohr effect: a. Bohr effect describes carbon monoxide poisoning. b. Bohr effect prevents oxygen binding to hemoglobin. c. Bohr effect allows effective oxygen discharge in tissues due to higher acidity (decreased pH) than in lungs. d.

A 68-year-old female who was admitted with shortness of breath. On your arrival, the patient appears drowsy and is on 10L of oxygen via a mask. You perform an ABG, which reveals the following results: • PaO2: 52.5 mmHg • pH: 7.29 • PaCO2: 68 mmHg • HCO3–: 26 What does the ABG show: Oxygenation (PaO2): pH: PaCO2: HCO3–: Interpretation: What symptoms or signs are associated with hypercapnia (↑CO2)?
The healthcare provider orders 90 mg of a drug IVPB q6h for a child. If the label on the drug vial reads 15mg/mL, how many milliliters will you withdraw from the vial to add to the volume control chamber? AND if the recommended concentration of the solution for infusion is 10mg/mL, how many more mL of liquid would you add to the volume control chamber (VCC) to achieve the recommended concentration?
A Er doctor orders IV normal saline solution to be infused at a rate of 140mL/hour for a patient admitted with mild dehydration and bronchitis. How many liters of saline will the patient receive during a 12 hour shift?
Mrs. Breathless is a 45-year-old female nurse with a history of asthma. She reports to the ED in the early morning with shortness of breath, blurred vision, headache, and restlessness. After several laboratory tests, the following ABG (arterial blood gases) lab results are confirmed: Blood pH=7.30 PaCO2 = 46 mm Hg HCO3 = 24 mEq/L. Based on the results of her ABG, which acid-base imbalance is Mrs. Breathless likely experiencing? Justify your answer by referencing the ROME mnemonic. What is the underlying pathophysiology of this disorder? What type of compensation is likely to take place? Why do you think Mrs. Breathless developed this imbalance? What are some of the contributing factors leading to this?
Determine and report the pressure of collected hydrogen gas in atmospheres. Report this result to one more digit than allowed by applying the rules of significant figures. (1 atm = 760 mm Hg, an exact conversion factor.) Determine the moles of hydrogen collected by substituting the appropriate quantities into the ideal gas equation and solving. Report this result to one more digit than allowed by applying the rules of significant figures. Notes: the gas temperature is the same as the listed temperature; R = 0.082057 L-atm/mol-K. Be mindful of units. Determine the experimental atomic mass of Cu. Round this result to the correct number of significant figures. Determine the percent relative error (= ????????????−?h????????? ? 100). The molar mass of Cu is 63.546 g/mol. Mass of copper before electrolysis 6.008 g Mass of copper after electrolysis 5.860 g Volume of H2 collected 58.9 mL Pressure of H2, PH2 720.8 mm Hg Temperature 24.0 oC
Harry ate a late meal at a cheap diner on the way home from work.A couple of hours later, he vomited three times, and then he consumed several packages of an antacid (mostly NaHCO3) over thenext several hours. By the evening of the next day, he was feelingbetter. During this ordeal, his blood pH did not deviate significantly.Select the mechanism(s) that helped maintain Harry’s pH within anormal range.(1) increased respiratory rate(2) increased H+ secretion by the renal tubule(3) decreased respiratory rate(4) decreased H+ secretion by the renal tubulea. 1 b. 2 c. 1,2 d. 3 e. 3,4
