What is metabolic alkalosis? - ANS ✓Bicarbonate excess caused when there is
a loss of acid or a gain in bicarb
HYPOKALEMIA will produce alkalosis
Etiology of metabolic alkalosis (8) - ANS ✓1. Severe vomiting
2. Excess gastric suctioning (continuous take all of acid)
3. Long-term diuretic therapy
4. Hyperaldosteronism (BP gets up, results to hypokalemia)
5. K+ deficit
6. Excess NaHCO3 intake (taking tums bc inc. in too much bicarb)
7. Cushing's syndrome
8. Excessive mineralocorticoids
CM of metabolic alkalosis: Neurologic - ANS ✓- Irritability &/or confusion
- Lethargy
- HA

(compensation)
Medical/nursing management for metabolic alkalosis - ANS ✓- Correct the
underlying acid-base disorder

level)

CM of respiratory acidosis: Cardiovascular - ANS ✓- Hypotension
- Peripheral vasodilation
- V. fib (r/t hyperkalemia from compensation)
- Warm, flushed skin
CM of respiratory acidosis: Respiratory - ANS ✓- Hypoventilation w/ hypoxia
- Rapid shallow breaths (body is trying to breath but lungs can’t expand as much
to do gas exchange)
Medical/nursing management for respiratory acidosis - ANS ✓- Improve
ventilation
- Bronchodilators, abx, anticoagulants
- Plum. physiotherapy
- Adequate hydration
- Mechanical ventilation (PRN)
- Monitor resp. status, I&O
What is respiratory alkalosis? - ANS ✓Hyperventilation
