A nurse is caring for a client who has acute kidney injury.
The client's ABGs are: pH: 7.26, PaCO2: 30 mm Hg, HCO3: 14 mEq/L. Which of the following acid imbalances should the nurse identify the client is experiencing?
Metabolic alkalosis.
Respiratory acidosis.
Metabolic acidosis.
Respiratory alkalosis.
The Correct Answer is C
Choice A rationale:
Metabolic alkalosis is incorrect because it would present with a high pH and high HCO3, which is not the case here.
Choice B rationale:
Respiratory acidosis is incorrect because it would present with a low pH and high PaCO2, which is not the case here.
Choice C rationale:
Metabolic acidosis is correct because it presents with a low pH and low HCO3, which matches the client’s ABG results.
Choice D rationale:
Respiratory alkalosis is incorrect because it would present with a high pH and low PaCO2, which is not the case here.

Correct Answer is B
Explanation
Choice A rationale:
Discarding any partial doses found in the cabinet in the sharps container is not the correct procedure. Partial doses should be wasted in the presence of another nurse.
Choice B rationale:
Verifying that the amounts of each medication counted match the amounts on the inventory record is the correct procedure. This ensures accurate accounting of controlled substances.
Choice C rationale:
Setting aside any controlled substances the nurse plans to give during her shift is not the correct procedure. Medications should be removed from the secure cabinet as needed.
Choice D rationale:
Co-signing any notations of wasting controlled substances on the previous shift is not the correct procedure. Wasting should be witnessed and co-signed at the time it occurs.
Correct Answer is B
Explanation
Choice A rationale:
Checking for a positive Chvostek’s sign is not relevant. This sign is associated with hypocalcemia, not with the lab values provided.
Choice B rationale:
The nurse should request a potassium replacement. The normal range for potassium is 3.5-5.0 mEq/L. A level of 3.0 mEq/L is low, indicating hypokalemia.
Choice C rationale:
Administering glucagon IM is not appropriate. The glucose level is within the normal range (70-110 mg/dL), so there is no need for glucagon.
Choice D rationale:
Discontinuing the TPN infusion is not the first action. The nurse should address the abnormal lab value (low potassium) first.
