Diabetes Mellitus in Children
Diabetes Mellitus in Children ( 31 Questions)
A nurse is caring for a child with DKA.
The child's blood glucose level is 300 mg/dL (16.7 mmol/L).
The nurse has started an intravenous insulin infusion and is monitoring the child's blood glucose levels closely.
Which of the following assessment findings would indicate that the child's DKA is improving?
Select all that apply.
A decrease in the child's blood glucose level from 300 mg/dL to 250 mg/dL would indicate an improvement in DKA. This is because DKA is characterized by hyperglycemia, and a decrease in blood glucose levels shows that the insulin infusion is working to correct the high blood sugar. The normal range for blood glucose levels in children is typically 70-140 mg/dL, so 250 mg/dL is still high but represents an improvement.
A decrease in ketones in the urine is another positive sign in the management of DKA. Ketones in the urine are a sign of metabolic acidosis, which is a hallmark of DKA. A reduction in ketones indicates that the body is shifting away from using fats for energy and is starting to correct the metabolic derangement. It's important to note that ketone levels are usually assessed qualitatively as negative, trace, small, moderate, or large, and a decrease from a higher level to a lower level is a positive sign.
An increase in the respiratory rate is not typically an indicator of DKA improvement. In fact, during DKA, the respiratory rate may increase as the body tries to compensate for the acidosis by blowing off carbon dioxide through rapid breathing. Therefore, a further increase in respiratory rate may not necessarily be a sign of improvement. Monitoring the respiratory rate is essential, but it doesn't directly indicate the resolution of DKA.
An increase in pH is a significant indicator of DKA improvement. In DKA, the blood becomes acidic due to the accumulation of ketones and the decreased pH levels. An increase in pH levels suggests that the acidosis is being corrected, which is a positive sign in the management of DKA. Normal blood pH levels for children typically range from 7.35 to 7.45.
Choice A rationale:
A decrease in the child's blood glucose level from 300 mg/dL to 250 mg/dL would indicate an improvement in DKA.
This is because DKA is characterized by hyperglycemia, and a decrease in blood glucose levels shows that the insulin infusion is working to correct the high blood sugar.
The normal range for blood glucose levels in children is typically 70-140 mg/dL, so 250 mg/dL is still high but represents an improvement.
Choice B rationale:
A decrease in ketones in the urine is another positive sign in the management of DKA.
Ketones in the urine are a sign of metabolic acidosis, which is a hallmark of DKA.
A reduction in ketones indicates that the body is shifting away from using fats for energy and is starting to correct the metabolic derangement.
It's important to note that ketone levels are usually assessed qualitatively as negative, trace, small, moderate, or large, and a decrease from a higher level to a lower level is a positive sign.
Choice C rationale:
An increase in the respiratory rate is not typically an indicator of DKA improvement.
In fact, during DKA, the respiratory rate may increase as the body tries to compensate for the acidosis by blowing off carbon dioxide through rapid breathing.
Therefore, a further increase in respiratory rate may not necessarily be a sign of improvement.
Monitoring the respiratory rate is essential, but it doesn't directly indicate the resolution of DKA.
Choice D rationale:
An increase in pH is a significant indicator of DKA improvement.
In DKA, the blood becomes acidic due to the accumulation of ketones and the decreased pH levels.
An increase in pH levels suggests that the acidosis is being corrected, which is a positive sign in the management of DKA.
Normal blood pH levels for children typically range from 7.35 to 7.45.
Choice E rationale:
A decrease in bicarbonate levels is not a sign of DKA improvement.
In DKA, bicarbonate levels are typically low due to the acidosis.
As treatment progresses and the acidosis resolves, bicarbonate levels may start to increase, indicating improvement.
Therefore, a decrease in bicarbonate levels would not be a positive sign in this context.
