A nurse is caring for a client who has chronic renal failure.
The client displays the following ABG results: pH 7.24, PaCO2 44 mm Hg, PaO2 84 mm Hg. HCO3 18 mEq/L, base excess -2, and O2 saturation 95%.
The nurse should conclude that the client has which of the following acid-base imbalances?
Respiratory acidosis.
Metabolic alkalosis.
Respiratory alkalosis.
Metabolic acidosis.
The Correct Answer is D
The client’s ABG results show a pH of 7.24, which is below the normal range of 7.35-7.45 and indicates acidosis.
The PaCO2 is within the normal range of 35-45 mm Hg, indicating that the acidosis is not caused by a respiratory issue.
The HCO3 level is 18 mEq/L, which is below the normal range of 22-28 mEq/L and indicates a primary metabolic cause for acidosis.
Respiratory acidosis is not indicated by the ABG results as the PaCO2 is within the normal range.
B) Metabolic alkalosis is not indicated by the ABG results as the pH and HCO3 levels are below their respective normal ranges.
C) Respiratory alkalosis is not indicated by the ABG results as the pH is below the normal range and the PaCO2 is within the normal range.

Correct Answer is D
Explanation
White rice is a low-potassium food that can be recommended for a client who has chronic kidney disease and must limit potassium intake.
Nonfat yogurt (choice A) contains moderate amounts of potassium and may not be the best choice for someone who needs to limit their potassium intake.
A medium baked potato with skin (choice B) is high in potassium and should be limited to a low-potassium diet.
Peanut butter (choice C) also contains moderate amounts of potassium and may not be the best choice for someone who needs to limit their potassium intake.
Correct Answer is B
Explanation
- A. "You should ask your provider about your plan." This response is appropriate because it acknowledges the client's desire to explore alternative treatments while directing them to the appropriate source for medical advice. It promotes client autonomy and ensures they receive accurate information from their healthcare provider.
- B. "Tell me what you know about chemotherapy." This response is also appropriate. It encourages the client to express their understanding and concerns about chemotherapy, allowing the nurse to identify any misconceptions and provide accurate information. This also opens the door for the client to express their concerns about vitamins and minerals, and why they want to persue that treatment.
- C. "I have never heard of any holistic treatment that is effective." This response is inappropriate because it dismisses the client's preferences and demonstrates a lack of respect for their autonomy. It also displays a lack of knowledge, as some holistic treatments can be used as supportive therapies.
- D. "The best way to treat your cancer is chemotherapy." This response is inappropriate because it is directive and does not allow the client to participate in decision-making. It also does not address the client's desire to explore alternative treatments.
