The nurse is planning an in-service for new RNs who will be working on a general pediatric unit. Which statements are appropriate to include when discussing normal acid–base balance?
1. The lungs are responsible for excreting excess carbonic acid from body.
2. The lungs reabsorb filtered bicarbonate.
3. The kidneys form bicarbonate if needed to restore balance.
4. The liver forms bicarbonate if needed to restore balance.
5. The liver synthesizes proteins needed to maintain osmotic pressure in the fluid compartments.
Correct Answer: 1,3,5
Rationale: Statements that the nurse educator will include in the in-service include: the lungs are responsible for excreting excess carbonic acid from body; the kidneys form bicarbonate if needed to restore balance; and the liver synthesizes proteins needed to maintain osmotic pressure in the fluid compartments. The kidneys, not the lungs, reabsorb filtered bicarbonate. The kidneys, not the liver, form bicarbonate to restore balance, if needed.
