The nurse is comparing diabetic ketoacidosis (DKA) to hyperglycemic hyperosmolar nonketotic syndrome (HHNS). What does the nurse identify as the main difference between the two disorders?
1. DKA and HHNS are caused by too much insulin in the body.
2. No insulin is present in DKA, whereas some insulin is present in HHNS.
3. DKA results in metabolic acidosis; HHNS results in metabolic alkalosis.
4. Dehydration is greater or more severe in DKA than in HHNS.
2
Rationale 1: In both conditions there is too little, rather than too much, insulin.
Rationale 2: Although high blood sugars are present in both DKA and HHNS, there is still insulin production with HHNS.
Rationale 3: DKA does result in metabolic acidosis; however, HHNS does not result in metabolic alkalosis.
Rationale 4: Dehydration is more severe in HHNS than in DKA.
