A client at your fitness center complains of a headache and seems disoriented. He appears ashen and has moist, cold skin. You know from his health history that he has Type II diabetes. Which of the…

Administering insulin would further lower the client's already deficient blood glucose, worsening the hypoglycemic episode and potentially precipitating loss of consciousness or seizure.

The client's cold moist skin, disorientation, and headache are hallmark signs of hypoglycemia - a dangerously low blood glucose state common in Type II diabetics who may have taken too much medication or not eaten adequately. Administering a fast-acting sugar source (glucose tablets, juice, or regular soda) rapidly raises blood glucose and can prevent progression to unconsciousness or seizure. This is the accepted first-aid response for a conscious hypoglycemic individual while awaiting emergency medical services.

Water contains no glucose and has no effect on blood sugar levels, making it useless for reversing the hypoglycemic state causing the client's symptoms.

Waiting without intervention risks rapid deterioration into unconsciousness or coma before EMS arrives, when the client is still conscious and able to ingest sugar safely.
