Correct Answer is B

Explanation

A. 0.9% sodium chloride, also known as Normal Saline, is an isotonic solution. It has the same concentration of solutes as blood plasma, which means it does not change the cell's fluid volume but rather maintains it. It is not considered hypotonic.

B. 0.45% sodium chloride, commonly known as Half Normal Saline, is a hypotonic solution. It has a lower concentration of sodium chloride compared to the normal saline and is used to provide hydration and to help correct electrolyte imbalances by allowing water to move into the cells.
C. Dextrose 5% in Lactated Ringer's is not a hypotonic solution. It is actually a type of hypertonic solution. Initially, dextrose 5% is isotonic, but once the dextrose is metabolized, the solution becomes hypotonic due to the electrolyte content of Lactated Ringer’s. However, the classification is generally based on the solution before metabolism, and it is not commonly used as a hypotonic solution.
D. Lactated Ringer's solution is an isotonic solution. It contains electrolytes in concentrations similar to those found in the body's plasma, and it is used to restore fluids and electrolytes. It does not have a hypotonic effect on cells.

A. Hct 48% B. Urine specific gravity 1.040 C. Blood creatinine 0.6 mg/dL D. Blood sodium 140 mEq/L

Correct Answer is B

Explanation

A. While a slightly elevated hematocrit can be associated with dehydration, it's not as specific as urine specific gravity.
B. This indicates concentrated urine, which is a classic sign of dehydration. Normal urine specific gravity is typically between 1.005 and 1.030.
C. This is a normal creatinine level and does not indicate dehydration.
D. This is within the normal range for sodium.
