Question

7. A 10-year old female enters the ER with shortness of breath. She has cyanosis of the lips (her lips are blue). According to her father, she has been coughing for about a week. Her temperature is 102.5 °F and her respirations are rapid and shallow. A chest x-ray indicates pneumonia in both lungs. Her arterial blood gasses (ABG) stats are pH: 7.45 PCO2 28 mm Hg HCO3: 21 mEq/L What ABI is she experiencing? Is it uncompensated, partially compensated, or compensated? Her PO2 (amount of oxygen in her blood) is 53, a low value. Why would you expect this value to be low? 8. A 74-year old widower enters the ER complaining of shortness of breath and chest pain. He says he has felt this way for a couple of days. His breathing is shallow and rapid. He has an anti-anxiety medication, but has not taken it. His ABG stats are pH: 7.45 PCO2: 22 mm Hg HCO3: 23 mEq/L What ABl is he experiencing? Is it uncompensated, partially compensated, or compensated? 9. A 24-year old athlete enters the ER disoriented. His skin smells of urine. His friend tells you that he has been pushing it really hard in the gym and has restricted his diet to only proteins and fats, with no carbohydrates. His ABG stats are pH: 7.33 PCO2: 24 mm Hg HCO3: 16 mEq/L What ABI is he experiencing? Is it uncompensated, partially compensated, or compensated?

Answer 1

Question 7 answer.

As per the mentioned ABG she is experiencing compensated respiratory alkalosis.

Interpretation:

1.PCO2 is low 28mmHg (normal range 35-45)

2. PH is on high side of normal 7.45 (normal pH is 7.35-7.45)

Therefore compensated respiratory alkalosis.

PO2 is 53 is low , it may be due to mucus displacing air in the alveoli caused by pneumonia
