ATI Acid Base Flashcards
DKA lab
low potassium 3.0- tell dr
Hyperkalemia
may cause prolonged PR interval and widened QRS complex
Low sodium
can cause change in mental status, confusion, lethargic
Isotonic dehydration
loss of water only, from vomiting and diarrhea. lab that shows response to fluid therapy- sodium 138
Sodium 155, what fluids to give
dont give 3% saline- hypertonic, will increase sodium.
These will decrease sodium:
Hypotonic- 5%dextrose and 0.45% saline, 5% dextrose with water
Isotonic- 0.9%saline
Potassium 3.0
orthostatic hypotension
Respiratory distress b/c acute pulmonary edema
place client in high fowlers to ease breathing
Risk of respiratory acidosis following surgery, teaching
incentive spirometer q1hr, move as much as possible, drink at least 1500 mL fluid/d, use PCA before pain gets worse
Calcium 8.4
initiate seizure precautions because pt is at risk for seizures b/c lower excitation threshold. Calcium can be given orally or IV
Hypomagnesemia
hyperactive deep tendon reflexes, decreased bowel sounds, shallow respirations, increased bp
Calcium 8.1
Priority assessment- cardiac rhythm. greatest risk is cardiac dysrhythmias.
also may have- hyperactive dtr, increased bowel sounds, diminished peripheral pulses
potassium 6.2
administer D50W and regular insulin IV. IV solution with high dextrose concentration and regular insulin will cause the K to move from the blood into the cells and decrease the serum potassium level.
Respiratory alkalosis
PaCO2 is decreased
Pt experienced fluid loss
administer prescribed IV fluids, encourage the pt to drink fluids, encourage pt to rise slowly when standing, weigh pt each morning
Respiratory alkalosis, resp 28/min
provide calming interventions for hyperventilation. need to calm down to allow for carbon dioxide to build up
