A nurse is reviewing the laboratory results of a client who has DKA. The client's ABG results are pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L. The nurse should identify that these values indicate which of the following acid-base imbalances?
Respiratory alkalosis
Metabolic alkalosis
Metabolic acidosis
Respiratory acidosis
The Correct Answer is C
A nurse reviewing the laboratory results of a client who has DKA should identify that the client's ABG results of pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L indicate metabolic acidosis. Metabolic acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a low bicarbonate level (less than 22 mEq/L).
The other options are not correct.
a) Respiratory alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a low PaCO₂ (less than 35 mm Hg).
b) Metabolic alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a high bicarbonate level (greater than 26 mEq/L).
d) Respiratory acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a high PaCO₂ (greater than 45 mm Hg).

Explanation
The statement by the client that indicates an understanding of the teaching is "I plan to take water aerobics classes at the gym near my house." Exercise is an important part of managing osteoarthritis, and water aerobics is a low-impact exercise that can help improve joint mobility and reduce pain.
Option ais incorrect because applying cold compresses may not be the most effective way to manage pain associated with osteoarthritis. Heat therapy is often more effective for this condition.
Option b is incorrect because limiting purine intake in the diet is recommended for clients with gout, not osteoarthritis.
Option d is incorrect because ibuprofen can be an effective pain reliever for clients with osteoarthritis.
Correct Answer is D
Explanation
The nurse should recommend that the client who has diminished breath sounds and paradoxical chest movement receive care first. This client is likely experiencing a tension pneumothorax, which is a life-threatening condition that requires immediate intervention.
Option a is incorrect because a client who has a head injury and whose pupils are fixed and dilated may have experienced brain death and may not be able to be resuscitated.
Option b is incorrect because a dislocated shoulder, while painful, is not immediately life-threatening. Option c is incorrect because a scalp laceration with intermittent bleeding can be managed with pressure and is not immediately life-threatening.
