Question

Severe dehydration (>9%) requires _____ with repeated boluses of _____ mL/kg of normal saline until adequate tissue perfusion is achieved.

a) Oral rehydration; 10
b) Intramuscular injection; 20
c) Intravenous therapy; 20
d) Intradermal injection; 5

Answer 1

Severe dehydration is treated with intravenous therapy, specifically with repeated boluses of 20 mL/kg of normal saline, an isotonic solution compatible with body fluids, to restore adequate tissue perfusion.

Step-by-step explanation:

Severe dehydration (>9%) requires intravenous therapy with repeated boluses of 20 mL/kg of normal saline until adequate tissue perfusion is achieved. Severe dehydration (>9%) requires intravenous therapy with repeated boluses of 20 mL/kg of normal saline until adequate tissue perfusion is achieved. The correct answer to the question is option c) Intravenous therapy; 20.

When dealing with severe dehydration, it is critical to restore fluid balance quickly to prevent complications. Normal saline is given intravenously because it is isotonic with respect to body fluids, helping to achieve fluid equilibrium without causing undue osmotic stress to the cells. This solution may be prepared in a medical setting by mixing the appropriate mass of sodium chloride with water to achieve the desired concentration.
