A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arterial blood gas (ABG) values include: pH 7.22 PaCO2 68 mm Hg Base excess -2 PaO2 78 mm Hg Oxygen saturation 80% Bicarbonate 28 mEq/L. Which of the following interpretations of the ABG values should the nurse make?
Metabolic acidosis
Respiratory acidosis
Metabolic alkalosis
Respiratory alkalosis
The Correct Answer is B
A. Metabolic acidosis
Metabolic acidosis is characterized by a low pH (< 7.35) and a decreased bicarbonate level (< 22 mEq/L). In this scenario, the pH is low (7.22), but the bicarbonate level is elevated (28 mEq/L), which does not support a diagnosis of metabolic acidosis.
B. Respiratory acidosis
Respiratory acidosis occurs when there is an accumulation of carbon dioxide (PaCO2 > 45 mm Hg), leading to a decrease in pH (< 7.35). In this case, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), consistent with respiratory acidosis.
C. Metabolic alkalosis
Metabolic alkalosis is characterized by a high pH (> 7.45) and an elevated bicarbonate level (> 26 mEq/L). In this scenario, the pH is low (7.22), and the bicarbonate level is also elevated (28 mEq/L), which does not support a diagnosis of metabolic alkalosis.
D. Respiratory alkalosis
Respiratory alkalosis occurs when there is a decrease in carbon dioxide (PaCO2 < 35 mm Hg), leading to an increase in pH (> 7.45). In this case, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), which is not consistent with respiratory alkalosis.

Correct Answer is A
Explanation
A. Withhold food and liquids until the client's gag reflex returns.
This is the correct action. After a bronchoscopy, the client's throat may be numb or irritated from the procedure, which can temporarily impair the gag reflex. Withholding food and liquids until the gag reflex returns reduces the risk of aspiration, where food or liquid enters the airway instead of the stomach. Aspiration can lead to pneumonia and other serious complications. Therefore, it's essential to assess the client's gag reflex before allowing them to eat or drink.
B. Irrigate the client's throat every 4 hours.
This action is not necessary and may even be harmful. Irrigating the client's throat every 4 hours could further irritate the throat and increase discomfort for the client. Unless specifically ordered by the healthcare provider for a specific reason, such as to remove secretions or debris, routine irrigation of the throat is not recommended after a bronchoscopy.
C. Have the client refrain from talking for 24 hours.
There is typically no need for the client to refrain from talking for 24 hours after a bronchoscopy. While the client may experience some throat discomfort and hoarseness, restricting talking for such an extended period is unnecessary and may cause undue stress or anxiety for the client. Unless specifically instructed by the healthcare provider for a valid reason, such as to allow vocal cord healing, there is no need to restrict talking for such a long duration.
D. Suction the client's oropharynx frequently.
Frequent suctioning of the client's oropharynx is not indicated unless there is a specific medical reason to do so. Excessive suctioning can cause trauma to the mucous membranes, increase the risk of infection, and exacerbate throat irritation. The decision to suction should be based on clinical assessment, such as evidence of secretions or if the client is having difficulty clearing their airway, rather than being performed routinely.
Correct Answer is D
Explanation
A. Pigeon
A pigeon chest, also known as pectus carinatum, is a deformity of the chest characterized by a protrusion of the sternum and ribs, resulting in a pigeon-like appearance of the chest. This deformity is not typically associated with COPD.
B. Funnel
A funnel chest, also known as pectus excavatum, is a deformity of the chest characterized by a depression or concavity in the sternum, resulting in a funnel-like appearance of the chest. This deformity is not typically associated with COPD.
C. Kyphotic
Kyphosis refers to an exaggerated forward curvature of the thoracic spine, leading to a hunched or rounded upper back. While individuals with severe COPD may develop kyphosis due to chronic respiratory muscle fatigue and increased work of breathing, kyphotic curvature is not specific to COPD and can occur in other conditions as well.
D. Barrel
In COPD (Chronic Obstructive Pulmonary Disease), the client's chest may take on a barrel shape. This is characterized by an increase in the anterior-posterior diameter of the chest, resulting in a more rounded appearance similar to that of a barrel. This change in chest shape is due to hyperinflation of the lungs, which occurs as a result of air trapping and increased residual volume in the lungs, common in COPD.
