Acidosis
High HCO3 is considered acidosis or alkalosis?
Ans: Alkalosis
Physiological difference in a child vs adult related to oxygenation:
Ans: Children have:
1. Immature immune system
2. Short, smaller airways (they can become obstructed with mucus or edema, may
need to be suctioned)
3. A short respiratory tract that allows infection to travel quickly to lower
airways
4. Larger tongue in proportion to mouth
Nursing interventions that promote oxygenation (including clearing of airways and
supporting gas exchange):
Ans: 1. Position in semi-fowlers to high fowlers
2. Children: place in position to facilitate drainage (postural drainage)
3. Increase fluid intake/breastfeeding
4. Keep babies nose clear (they breathe through nose)
5. Promote smoking cessation
6. Administer meds/oxygen
7. Provide rest periods during ADLs

8. Encourage effective coughing, or suctioning to remove secretions
9. Encourage deep breathing and use of an incentive spirometer
10. Encourage water intake (helps break mucus up)
11. Encourage pursed lip breathing
What causes respiratory alkalosis?
Ans: Hyperventilation: anxiety attack, fear
What causes respiratory acidosis?
Ans: Hypoventilation: COPD, opioids, pneumothorax, asthma
What causes metabolic alkalosis?
Ans: Vomiting, prolonged nasogastric suctioning
What causes metabolic acidosis?
Ans: Diarrhea (comes from ASS), kidney failure, DKA
What do you want patients with respiratory alkalosis to do?
Ans: Decrease respiratory rate to retain carbon dioxide. Patient is breathing
too fast expelling too much CO2. Try having them breath into a paperbag.
What do you want patients with respiratory acidosis to do?
Ans: Increase respiratory rate, to expel carbon dioxide. They aren't breathing
fast/deep enough causing CO2 to build-up in the body. Have the patient try
pursed lip breathing.
