Answer 18

1) calcium gluconate
2) insulin
3) stop k+ solutions/K+ sparing drugs
4) bicarb (below 7.2 pH)

Question 19

calcium gluconate

Answer 19

• stabilizes myocytes

- prevents arrhythmia

Question 20

Insulin

Answer 20

• Lowers serum K+

- Shifts K+ into cells

Question 21

K+ holding drugs

Answer 21

• ACE inhibitors
• Beta blockers
• Potassium sparing diuretics

Question 22

Diabetic crisis

Answer 22

• high blood glucose -> excess diuresis

- depletes fluids, K+, and Na+

Answer 23

• restore volume
• K+ supplementation
• insulin

Question 24

Answer 25

mEq = (desired change) (TBV)

Question 26

CaCl dose

Answer 26

10mg/kg = 0.1 increase

Question 27

Answer 27

- not used for resuscitation | - treats edema

Question 28

resuscitation fluids

Answer 28

- RBC or FFP (not NaCl) | - 500 mL bolus

Question 29

Daily fluid maintenance requirements

Answer 29

-25-35 mL/kg/day - 500 - 1000 mL of insensible losses - 1000 - 1500 mL urine output

Question 30

early phase fluid shift following injury

Answer 30

- water is retained (ADH/aldosterone secretion) - oliguria common after surgery - negative charges lost (K+ shift)

Question 31

late phase fluid shift following injury

Answer 31

- anabolic - cells in sponge phase - NA+ and H2O move into ECF - K+ reuptake into cells
