Question

A 65-year-old male patient is admitted to the ICU following a car accident. He was intubated, put on a mechanical ventilator, and prescribed IV normal saline and parenteral nutrition. After a few days, he has the following lab values: Na 141 mEq/L, Cl 117 mEq/L, Creatinine 0.8 mg/dL, and BUN 14 mg/dL. An arterial blood sample was drawn and the patient ABGs revealed the following: pH 7.29, PO2 95 mm Hg, PCO2 35 mm Hg, and HCO3 21 mEq/L. What is the patient's acid-base abnormality? a. Hyperchloremic normal AG metabolic acidosis b. Mixed hyperchloremic normal AG metabolic acidosis and high AG metabolic acidosis c. High AG metabolic acidosis d. High AG metabolic acidosis and concurrent metabolic alkalosis e. Mixed metabolic acidosis and respiratory acidosis

3. In a man undergoing surgery, it was necessary to aspirate the contents of the upper gastrointestinal tract. After surgery, the following values were obtained from an arterial blood sample: pH 7.55, PCO2 52 mm Hg and HCO3- 40 mmol/l. What is the underlying primary acid-base disorder (first), is there compensation (second)? a. Metabolic Acidosis, incomplete compensation with respiratory alkalosis b. Metabolic Alkalosis, full compensation with respiratory acidosis c. Respiratory Acidosis, full compensation with metabolic alkalosis d. Respiratory Alkalosis, incomplete compensation with metabolic acidosis e. Metabolic Alkalosis, incomplete compensation with respiratory acidosis 4. A young woman is found comatose, having taken an unknown number of sleeping pills an unknown time before. An arterial blood sample yields the following values: • pH: 6.90 • HCO3-: 13 mEq/liter • PaCO2: 68 mmHg This patient's acid-base status is most accurately described as a. Uncompensated metabolic acidosis b. Uncompensated respiratory acidosis c. Mixed respiratory and metabolic acidosis d. Respiratory acidosis with partial renal compensation e. Fully compensated metabolic acidosis 5. A student is nervous for a big exam and is breathing rapidly. Which do you expect from the followings? a. Metabolic Acidosis b. Metabolic Alkalosis c. Respiratory Acidosis d. Respiratory Alkalosis e. Mixed Acidosis and Alkalosis

00:01 So, it has been given that a patient has undergone a surgery and we have to aspirate him for his the content of his upper gastrointestinal tract.
00:10 Okay.
00:11 And these are the following that has been obtained from his arterial blood sample.
00:17 So as you can see that the ph is 7 .55.
00:21 So normal ph is from the range 7 .35 to 7 .45.
00:26 So if it is more than 7 .55, right? that means here, alkylosis is occurring.
00:33 If it was less, then it would have an acidosis.
00:35 Okay.
00:36 Then we see that the pco2 is 55mm ag and hco3 is 40 mm per liter.
00:43 Okay.
00:44 So that means what it means that metabolic alkalosis is present.
00:50 Okay.
00:50 That means the cost of alkalosis was due to metabolic reason.
00:53 And the carbon dioxide, okay, it is increased.
00:58 So that it can compensate for the alkalosis here.
01:02 Okay...
