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

CM of metabolic alkalosis: Neuromuscular - ANS ✓- Tetany (d/t K+)
- Tremors
- Tingling of fingers & toes
- Muscle cramps
- Sz
CM of metabolic alkalosis: Gastrointestinal - ANS ✓N, V, anorexia
CM of metabolic alkalosis: Cardiovascular - ANS ✓- Tachycardia
- Dysrhythmia (r/t hypokalemia from compensation)
CM of metabolic alkalosis: Respiratory - ANS ✓Hypoventilation
(compensation)
Medical/nursing management for metabolic alkalosis - ANS ✓- Correct the
underlying acid-base disorder
- Restore fluid vol
- Monitor I&O
- Monitor for ECG & neurologic changes
What is respiratory acidosis? - ANS ✓Hypoventilation

If CO2 is not eliminated from the blood, acidosis results from accumulation of
carbonic acid
Etiology of respiratory acidosis (10) - ANS ✓1. COPD (holding in so inc. CO2
level)
2. Sedative overdose
3. Chest wall abnormality (obesity, bc they have to breath harder to overcome
pressure)
4. Pneumothorax
5. Multiple sclerosis
6. Myasthenia gravis
7. Atelectasis
8. Severe pneumonia (less gas exchange)
9. Resp. muscle weakness
10. Mechanical under ventilation
CM of respiratory acidosis: Neurologic - ANS ✓- Lethargy
- Confusion
- Dizziness
- HA
- Coma
CM of respiratory acidosis: Neuromuscular - ANS ✓Sz

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
Excreting too much CO2
Etiology of respiratory alkalosis d/t hyperventilation (6) - ANS ✓1. Hypoxia
