Answer Section

MULTIPLE CHOICE

1.ANS:C

The nurse is administering a balanced solution. Hypotonic, isotonic, and hypertonic solutions refer only to those solutions whose osmolarity is, respectively, less than, equal to, or greater than that of plasma—not to their electrolyte or ionic contents.

PTS: 1 KEY: Cognitive Level: Analysis

2. ANS:A

The solution of 0.45% sodium chloride is hypotonic and has an osmolarity of 155. It is one of the only hypotonic solutions used in clinical practice. The range for hypotonic solutions is below 250 mOsm. Five percent dextrose in water has an osmolarity of 252 mOsm and is isotonic; 10% dextrose in water has an osmolarity of 505 mOsm and is hypertonic; 5% dextrose and 0.9% sodium chloride combined has an osmolarity of 560 mOsm and is hypertonic.

3. ANS:B

Albumin is a natural plasma protein prepared from donor plasma. Colloid solutions contain protein or starch molecules that remain distributed in the extracellular space and do not form a “true” solution.

PTS: 1 KEY: Cognitive Level: Application

4. ANS:B

The first concern for a client requiring replacement is whether the kidneys are functioning well enough to permit the therapy.

5. ANS:C

Saline solutions are the only solution to be used with any blood product. Dextrose solutions cause hemolysis of cells. Lactated Ringer’s solutions contain calcium ions that can also hemolyze the blood cells.

6. ANS:D

Solutions that contain dextrose and hypotonic saline provide more water than is required for excretion of salt and are also useful as hydrating fluids.
