A nurse is caring for a client whose arterial blood gas results show the following results:. pH: 7.2. PaCO2: 50 mm Hg. HCO3: 24 mEq/L. The nurse should identify the client is experiencing which of the following acid-base conditions?
Respiratory acidosis.
Metabolic alkalosis.
Metabolic acidosis.
Respiratory alkalosis.
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A rationale:
Check the client's respiratory rate and lung sounds When an IV bag is unexpectedly empty, it is important to assess the client for potential complications, especially if the client was receiving fluid therapy. Checking the respiratory rate and lung sounds is essential to ensure there are no signs of respiratory distress, such as crackles or wheezing, which could indicate fluid overload or a pulmonary issue.
Choice B rationale:
Request NPO status for the client Requesting nothing by mouth (NPO) status is not the immediate action required when an IV bag is empty. The priority is to assess the client's condition and address any potential issues first.
Choice C rationale:
Elevate the head of the bed to high Fowler's Elevating the head of the bed to high Fowler's is a measure to assist with preventing aspiration during oral intake. It is not the primary action required in this situation, where assessing the client's respiratory and fluid status is more important.
Choice D rationale:
Measure the client's temperature Measuring the client's temperature is not the immediate priority in this scenario. Assessing the client's respiratory and fluid status is more critical to identify any potential issues associated with the empty IV bag. .
Correct Answer is A
Explanation
The correct answer is A. Captopril.
Choice A: Captopril Captopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat conditions like high blood pressure and heart failure. One of the common side effects of ACE inhibitors is a persistent, non-productive cough. This cough occurs due to the accumulation of bradykinin, a potent peptide that can induce coughing.
Choice B: Metoprolol Metoprolol is a beta-blocker used to treat high blood pressure and heart failure. Common side effects include dizziness, slow or irregular heartbeat, and unusual tiredness or weakness. However, it is not typically associated with a non-productive cough.
Choice C: Furosemide Furosemide is a loop diuretic used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or a kidney disorder. While it can cause side effects like diarrhea, constipation, and loss of appetite, a non-productive cough is not a typical side effect of Furosemide.
Choice D: Digoxin Digoxin is used to treat heart failure and irregular heartbeat. Common side effects include dizziness, slow or irregular heartbeat, and unusual tiredness or weakness. However, a non-productive cough is not a typical side effect of Digoxin.
