A nurse is reviewing a client's laboratory results.

Which of the following findings should the nurse report to the provider?

Choice A rationale:

The client's arterial blood gas (ABG) results indicate a low pH (acidemia) and high PaCO2, which is characteristic of respiratory acidosis. Respiratory acidosis occurs when there is inadequate removal of carbon dioxide (CO2) from the body, leading to an accumulation of CO2 and a decrease in pH. In this case, the high PaCO2 (50 mm Hg) indicates that the client is retaining carbon dioxide, likely due to impaired ventilation. The normal pH range is 7.35 to 7.45, and the normal PaCO2 range is 35 to 45 mm Hg. These ABG values reflect an acid-base imbalance in the respiratory system, specifically, respiratory acidosis.

Choice B rationale:

Metabolic alkalosis is characterized by an elevated pH and an increase in bicarbonate (HCO3) levels. This is not the condition described in the client's ABG results, as the pH is low (acidemic) and HCO3 levels are within the normal range (24 mEq/L).

Choice C rationale:

Metabolic acidosis is characterized by a low pH and a decreased HCO3 level. The client's ABG results do not align with metabolic acidosis since the pH is low (acidemic) and the HCO3 level is within the normal range (24 mEq/L).

Choice D rationale:

Respiratory alkalosis is characterized by a high pH and low PaCO2. The client's ABG results do not match this condition as the pH is low (acidemic) and the PaCO2 is high (50 mm Hg), indicating respiratory acidosis. Therefore, choice A, respiratory acidosis, is the correct interpretation of the ABG results.

Choice A rationale:

Facial flushing. Facial flushing is not typically associated with atelectasis. Atelectasis is the collapse of a portion of the lung, which can lead to decreased oxygenation and respiratory distress but does not directly cause facial flushing. Flushing may be related to other factors such as fever or allergic reactions.

Choice B rationale:

Dry cough. A dry cough can be a common symptom of atelectasis. As the lung tissue collapses and airways become obstructed, it can lead to irritation and a dry, non-productive cough as the body attempts to clear the airway. So, a dry cough is an expected finding in a client with atelectasis.

Choice C rationale:

Decreasing respiratory rate. A decreasing respiratory rate is not typically associated with atelectasis. In fact, atelectasis often leads to an increased respiratory rate as the body tries to compensate for the reduced oxygen exchange. The patient may experience tachypnea (rapid breathing) as a result.

Choice D rationale:

Increasing dyspnea. Increasing dyspnea is a common and expected finding in a client with atelectasis. As lung tissue collapses and oxygen exchange is compromised, the patient will likely experience worsening shortness of breath. This is a concerning symptom and should be closely monitored, as it may indicate a need for intervention to improve lung expansion and oxygenation.
