Hyperosmolar Hyperglycemic Syndrome (HHS)

A metabolic complication of uncontrolled type 2 diabetes, similar in severity to diabetic ketoacidosis but without ketosis and acidosis.

Diabetic Ketoacidosis (DKA)

Shortage of insulin resulting in hyperglycemia and production of ketones; only occurs in T1D

insulin needs my double or quadruple by the end of pregnancy

Somogyi phenomenon

A rebound phenomenon that occurs in clients with type 1 diabetes mellitus. Normal or elevated blood glucose levels are present at bedtime; hypoglycemia occurs at about 2 to 3 am. Counterregulatory hormones, produced to prevent further hypoglycemia, result in hyperglycemia (evident in the prebreakfast blood glucose level).

administering fluid replacement

Which instruction would be included in the teaching plan? alcohol can be consumed, with its calories counted in the diet unlimited amounts of sugar substitutes can be used as desired alcohol should not be used in cooking because it adds too many calories special dietetic foods are needed because many regular foods cannot be used

alcohol can be consumed, with its calories counted in the diet
