A woman at 12 weeks' gestation comes to the clinic for her first prenatal visit.
After completing a health history, the nurse should discuss which topic about pregnancy at this initial visit?

Choice A rationale:
Hyperglycemia is a key symptom of DKA. It occurs when there is an insufficient amount of insulin in the body to allow glucose to enter cells for use as energy. As a result, the body begins to break down fat for fuel, leading to the production of ketones and causing blood glucose levels to rise. Normal blood glucose levels are between 4.0 to 6.0 mmol/L when fasting and up to 7.8 mmol/L two hours after eating2.
Choice B rationale:
Ketonuria, or the presence of ketones in the urine, is another symptom of DKA. When the body breaks down fat for energy, ketones are produced. If too many ketones build up in the blood, they can spill over into the urine1.
Choice C rationale:
Metabolic acidosis occurs in DKA due to the accumulation of ketones in the blood. Ketones are acidic, and when they build up in the blood, they cause the blood to become more acidic, leading to metabolic acidosis1.
Choice D rationale:
Hypokalemia is not a symptom of DKA. In fact, patients with DKA often have high potassium levels in their blood at presentation because acidosis causes potassium to move from inside the cells into the bloodstream1. However, during treatment for DKA, when insulin is administered and acidosis is corrected, potassium moves back into the cells and can lead to low potassium levels or hypokalemia1.
Choice E rationale:
Dehydration is a common symptom of DKA. High blood glucose levels lead to increased urination as the body tries to get rid of the excess glucose. This can result in dehydration1.
Choice F rationale:
Kussmaul respirations are a type of hyperventilation that occurs in DKA as the body tries to get rid of excess acids (ketones) through the lungs by breathing rapidly and deeply1.

The correct answer and explanation is:

b) Consecutive evening serum glucose greater than 260 mg/dL.

This is the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. Consecutive evening serum glucose greater than 260 mg/dL indicates hyperglycemia, which means that the client's blood sugar is too high and not well controlled by the insulin dose.

The PN should report this finding to the healthcare provider and expect a possible adjustment in the insulin regimen.

a) States her feet are constantly cold along with feeling numb.

This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus.

States her feet are constantly cold along with feeling numb may indicate peripheral neuropathy, which is a complication of diabetes that affects the nerves in the feet and legs. It is caused by chronic high blood sugar levels over time, not by a single dose of insulin.

c) A wound on the ankle that starts to drain and becomes painful.

This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. A wound on the ankle that starts to drain and becomes painful may indicate an infection, which is a risk factor for diabetic clients due to impaired wound healing and immune function. It is not directly related to the insulin dose, although it may affect the blood sugar levels and require more insulin.

d) Reports nausea in the morning but still able to eat breakfast.

This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. Reports nausea in the morning but still able to eat breakfast may indicate morning sickness, which is a common symptom of pregnancy. It is not related to the insulin dose, although it may affect the blood sugar levels and require more frequent monitoring and adjustment.
