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 D
Explanation
A. Position the client on the nonoperative side.
Positioning the client on the nonoperative side after a pneumonectomy may not be the best choice. The positioning of the client post-pneumonectomy should be based on factors such as the individual's comfort, respiratory status, and any specific instructions from the healthcare provider. Placing the client on the nonoperative side may inadvertently put pressure on the surgical site, leading to discomfort or potential complications.
B. Monitor respiratory status every 8 hr.
Monitoring respiratory status every 8 hours is not sufficient for a client post-pneumonectomy. After such a major surgical procedure, respiratory status should be closely monitored and assessed more frequently, especially in the immediate postoperative period. This frequency allows for the early detection of any signs of respiratory distress, such as decreased oxygen saturation, dyspnea, or abnormal breath sounds, as well as complications like pneumothorax or atelectasis.
C. Elevate the head of the bed to a 15° angle.
Elevating the head of the bed to a 15° angle is a general recommendation for clients postoperative to promote respiratory function and reduce the risk of aspiration. However, after a pneumonectomy, the positioning of the client may vary based on their individual condition and surgical approach. It's important to follow the healthcare provider's specific instructions regarding positioning for optimal recovery. The angle of elevation may need to be adjusted based on the client's comfort and respiratory status.
D. Encourage the client to splint the incision when coughing.
After a pneumonectomy, it's crucial to encourage the client to splint the incision when coughing. Splinting the incision with a pillow or hands helps to reduce pain and prevent strain on the surgical site, promoting healing and minimizing the risk of complications such as wound dehiscence (opening of the surgical incision).
Correct Answer is A
Explanation
A. Acute bronchospasm:
Albuterol (Proventil) is commonly used to treat acute bronchospasm, which is characterized by sudden constriction of the muscles surrounding the airways. This constriction leads to narrowing of the air passages, making it difficult to breathe. Albuterol works as a bronchodilator by relaxing these muscles, thereby opening up the airways and relieving symptoms such as wheezing, shortness of breath, and chest tightness. It is commonly used to manage conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, where bronchospasm is a prominent feature.
B. Acute allergies:
Albuterol (Proventil) is not typically used to treat acute allergies. While it can help alleviate symptoms such as wheezing and shortness of breath that may occur as a result of allergic reactions affecting the airways, its primary indication is for bronchospasm associated with respiratory conditions like asthma and COPD. Antihistamines and corticosteroids are more commonly used to manage allergic reactions and their associated symptoms.
C. Nasal congestion:
Albuterol (Proventil) is not indicated for the treatment of nasal congestion. Nasal congestion primarily involves swelling and inflammation of the nasal passages, which are not directly affected by albuterol. Decongestants such as pseudoephedrine or nasal corticosteroids are typically used to relieve nasal congestion by reducing inflammation and swelling in the nasal passages.
D. Dyspnea on exertion:
Albuterol (Proventil) may help alleviate dyspnea (shortness of breath) on exertion, particularly if it is caused by bronchospasm or exercise-induced bronchoconstriction. By relaxing the muscles around the airways, albuterol can improve airflow and ease breathing difficulties associated with exertion. However, it is important to note that albuterol is primarily indicated for the treatment of acute bronchospasm rather than dyspnea on exertion unrelated to bronchospasm. Other interventions, such as oxygen therapy or addressing underlying cardiovascular conditions, may be necessary to manage dyspnea on exertion in those cases.
