h h h h h h h
a. Sodium

c. Potassium

ANS: A h
Sodium is the most abundant cation in the blood. Potassium is the predomin
h h h h h h h h h h h h
ant intracellular cation. Chloride is an anion (negatively charged) rather t
h h h h h h h h h h
han a cation (positively charged). Magnesium is foundpredominantly ins

7. The nurse receives the patient’s most recent blood work
h h h h h h h h
results. Which laboratory value is of greatest concern?
h h h h h h h
a. Sodium of 145 mEq/L h h h
b. Calcium of 15.5 mg/dL h h h
c. Potassium of 3.5 mEq/L h h h

h
Normal calcium range is 8.4 to 10.5 mg/dL; therefore, a value of 15.5 mg/dL
h h h h h h h h h h h h h
is abnormally high and of concern. The rest of the laboratoryvalues are
h h h h h h h h h h h h h h
within their normal ranges: sodium 136 to 145 mEq/L; potassium
h h h h h h h h h
3.5 to 5.0 mEq/L; and chloride 98 to 106 mEq/L.

8. The nurse observes that the patient’s calcium is elevated. When
h h h h h h h h h
checking the phosphate level, what does the nurse expect to see?
h h h h h h h h h h
a. Increased
, b. Decreased
c. Equal to calcium h h
d. No change in phosphate
h h h
ANS: B h
Phosphate will decrease. Serum calcium and phosphate have an inverse rela

tionship. When one is elevated, the other decreases, except in somepatie
h h h h h h h h h h h
nts with end-stage renal disease.

b. A teenager with a sprained ankle and excessive edema

The infant should be seen first. An infant’s proportion of total body water(7

0% to 80% total body weight) is greater than that of children or adults. In
