The nurse suspects that a client’s body is attempting to correct an acid–base imbalance. How will this imbalance be corrected?

1. Slow but efficient respiratory regulation will occur.
2. Primary regulation is through GI system losses.
3. Kidney regulation is powerfully effective.
4. The cardiovascular system is the major buffer.

ANSWER

Correct Answer: 3
Rationale 1: Respiratory regulation is rapid, but temporary.
Rationale 2: The gastrointestinal system is not involved in the regulation of acid–base balance.
Rationale 3: Renal regulation is slower, but powerfully effective.
Rationale 4: The cardiovascular system is not involved in the regulation of acid–base balance.
