Zorluk: KolayPhysiological Adaptation

A nurse is evaluating the most recent arterial blood gas (ABG) results for a client who was admitted with a severe asthma exacerbation. The results are: pH 7.28, PaCO2 56 mm Hg, and HCO3 24 mEq/L. Which of the following acid-base imbalances should the nurse identify?

  1. Uncompensated respiratory acidosisCevap
  2. B
    Uncompensated respiratory alkalosis
  3. C
    Uncompensated metabolic acidosis
  4. D
    Uncompensated metabolic alkalosis

Cevap

Uncompensated respiratory acidosis
The client's pH is below the normal range (7.35-7.45), indicating acidosis. The PaCO2 is elevated above the normal range (35-45 mm Hg), which points to a respiratory cause. The bicarbonate (HCO3) level is within the normal range (22-26 mEq/L), meaning the kidneys have not yet begun to compensate. Therefore, the results definitively indicate uncompensated respiratory acidosis.

Adım Adım Çözüm

1
Evaluate the pH level to determine if the client is in acidosis or alkalosis.
The pH is 7.28, which is less than the normal range of 7.35 to 7.45, indicating acidosis.
Determining the primary acid-base status is the first step in ABG interpretation.
2
Evaluate the PaCO2 level to determine if the cause is respiratory.
The PaCO2 is 56 mm Hg, which is greater than the normal range of 35 to 45 mm Hg, indicating a respiratory etiology for the acidosis.
Identifying whether the respiratory parameter aligns with the pH abnormality determines if it is a primary respiratory issue.
3
Evaluate the HCO3 level to determine if the body has begun to compensate.
The HCO3 is 24 mEq/L, which is within the normal range of 22 to 26 mEq/L.
A normal metabolic parameter in the presence of an abnormal pH and respiratory parameter indicates that renal compensation has not yet occurred.
