An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units each morning. Which finding should the practical nurse (PN) document as evidence that the amount of insulin is inadequate? (Reference Range: Glucose [0 to 50 years: less than 140 mg/dL or less than 7.8 mmo/L]).

The correct answer is choice A. Consecutive evening serum glucose greater than 260 mg/dL. Choice A rationale: A consecutive evening serum glucose greater than 260 mg/dL indicates persistent hyperglycemia. Inadequate NPH insulin dosage may lead to consistently high blood glucose levels, which can result in various complications. Choice B rationale: The complaint of cold feet and numbness is not a specific indicator of inadequate insulin dosage. Neuropathy and circulation issues can occur with poorly controlled diabetes, but they are not solely indicative of inadequate insulin. Choice C rationale: Nausea in the morning, even with the ability to eat breakfast, does not necessarily point to inadequate insulin dosage. It could be due to various factors, including dietary choices or other medical conditions. Choice D rationale: The wound on the ankle that starts to drain and becomes painful is not a specific sign of inadequate insulin dosage. Poorly controlled diabetes can lead to delayed wound healing, but it does not necessarily indicate that the current insulin dosage is insufficient.
