Q

Metabolic acidosis
Causes?

A

**Bicarb low ** - GI loss (diarrhea)
Acid high - increase in lactic acid (poor perfusion, carbon monoxide poisioning), DKA, toxin
Impaired renal exretion (not excreting acid)
alcoholism, starvation

Q

What is compensation for metabolic acidosis
Nursing interventions - Monitor what labs

A

Lungs compensate by increasing resp/min to blow off co2
Monitor labs, serum lactic acid, replace fluids and electrolytes

Q

Metabolic Alkalosis
Reasons

A

Gi loss (vomit, suction)
Ingesting too much bicarb (antiacids)

Q

Respiratory acidosis
Causes
Acute vs Chronic
S/S
Compensation
Nursing intervention

A

Cause: hypoventilation/breathing slow
Acute - airway obstruction (choking, aspiration),chemical depression - overdose. Weak lungs - guillain barre, spinal cord injury
Chronic - obesity, COPD, emphysema
S/S hypoxia, confusion, lethargy, drowisness, headache
Compensation - secrete more H+, reabsorb bicarb, kidneys slow
Nursing interventions - Improve air way, HOB up, suction, O2, medications, poss IV push bi carb

Q

Respiratory Alkalosis
Causes
S/S - late
Compensation
Nursing interventions

A

Causes: hyperventilation/breathing fast, releasing too much acid, panic attack, pneumonia, asthma exacerbation, pE, fever, high altitude, improper vent setting
**S/S ** lightheaded, dizzy, confusion, tachycardia, calcium imbalances (numbness & tingling), arrhythmias Late = seizure/coma

Q

Hyperphosphatemia
Causes & always assoc w/?
S/S
Interventions

A

Normal 2.7-4.5 mg/dl (4.5 mg/dl+)
Causes: From tumor lysis syndrome, decreased renal excretion, increased renal reabsorption (hyperparathyroidism), acidosis, hypoparathyroidism. always assoc with hypocalcemia
S/S - numbness, tingling, muscle spasms, tetany, larynogspasm, stridor, chvosteks and trousseau signs

Q

Hyponatremia
Causes
S/S
Interventions
What precautions?
Replacing too quickly?

A

<135
Causes - too little sodium or too much water
* Sodium loss: Gi loss - vomit, NG suction, renal losses, diuretics, adrenal insufficiency, burns, fasting diets
* Excess water -Hypotonic IV fluids, polydipsia, cirrhosis, HF, SIADH

S/S - neurologic, cerebral edema, headache, nausea, vomiting, lethargy, confusion, seizures, coma.
Nursing interventions - monitor serum sodium, seizure precautions, replace sodium, fluid restriction, loop diuretics, don’t increase sodium too fast can lead to OSMOTIC DEMYELINATION SYNDROME = brain damage, monitor I &O
