A nurse is reviewing the ABG results for a client. The client's results are pH 7.47, PaCO2 30 mm Hg, HCO3 25 mEq/L, and SaO2 90%. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
Metabolic acidosis.
Respiratory acidosis.
Metabolic alkalosis.
Respiratory alkalosis.
The Correct Answer is C
Choice A rationale:
Metabolic acidosis is not the correct acid-base imbalance for the given ABG results. Metabolic acidosis is characterized by a low pH (acidic), low bicarbonate (HCO3) levels, and a compensatory decrease in the PaCO2. In the provided ABG results, the pH is elevated, and both the PaCO2 and HCO3 levels are within normal ranges.
Choice B rationale:
Respiratory acidosis is also not the correct acid-base imbalance for the given ABG results. Respiratory acidosis occurs when there is an elevation in PaCO2 due to inadequate ventilation, leading to an acidic pH. In the provided ABG results, the pH is elevated, and the PaCO2 level is within normal range.
Choice C rationale:
Metabolic alkalosis is the correct acid-base imbalance for the given ABG results. Metabolic alkalosis is characterized by an elevated pH, elevated bicarbonate (HCO3) levels, and a compensatory increase in PaCO2. In this case, the pH is higher than the normal range, the HCO3 level is elevated, and the PaCO2 is also slightly increased as the body attempts to compensate.
Choice D rationale:
Respiratory alkalosis is not the correct answer based on the provided ABG results. Respiratory alkalosis is marked by an elevated pH and a decrease in PaCO2 due to excessive ventilation. In the given ABG results, the pH is elevated, but the PaCO2 is not decreased; it's within the normal range.

Correct Answer is B
Explanation
Choice A rationale:
Using the cane to support body weight is not the correct technique. The purpose of a cane is to provide balance and support, not to bear the entire body weight. Placing the entire body weight on the cane can lead to instability and falls.
Choice B rationale:
Placing the cane next to the unaffected leg (right leg in this case) is the correct technique. This positioning provides additional support and stability on the side opposite to the affected leg. This helps in maintaining balance and reducing the risk of falling.
Choice C rationale:
The type of cane is not as relevant as using it correctly. The material of the cane doesn't impact the client's understanding of how to use it safely. While using a wooden cane might be acceptable, the material itself is not an indication of the client's understanding of safe cane use.
Choice D rationale:
Moving the right leg forward first is not the correct technique for using a cane. The correct foot to move forward first is the affected leg, in this case, the left leg. This allows the client to maintain a stable base of support while moving.
Correct Answer is D
Explanation
Choice A rationale:
Using a 5-mL syringe to flush the catheter is not the best choice. Central venous access devices typically require a larger syringe for flushing to prevent excessive pressure and potential damage to the catheter. A smaller syringe like the 5-mL syringe can create higher pressure, which could cause complications.
Choice B rationale:
Changing the site dressing and stabilization device every 24 hours is not the recommended practice. The dressing and stabilization device should be changed according to facility policy and as needed, but a rigid 24-hour schedule is not necessary and might increase the risk of infection due to unnecessary exposure.
Choice C rationale:
Expecting blood to appear in the catheter lumen after flushing is incorrect. Blood in the catheter lumen after flushing could indicate complications such as a dislodged catheter or other issues requiring immediate attention. The catheter should ideally remain patent without the presence of blood.
Choice D rationale:
This is the correct choice. Using chlorhexidine solution to clean the catheter is an evidence-based practice to prevent infection at the insertion site. Chlorhexidine has broad-spectrum antimicrobial properties and helps reduce the risk of catheter-related infections.
