When developing a teaching plan for an adolescent male who was recently diagnosed with Type 1 diabetes mellitus, the nurse should instruct the client to eat a source of sugar if which symptom occurs?

The client should be instructed to eat a source of sugar if he experiences profuse perspiration, which may indicate hypoglycemia or low blood sugar. Other symptoms of hypoglycemia include shakiness, confusion, dizziness, and weakness. Eating a source of sugar, such as a glucose tablet, fruit juice, or candy, can quickly raise blood sugar levels and alleviate symptoms of hypoglycemia. A racing pulse, excessive thirst, and seeing spots are not typically associated with hypoglycemia.
