The nurse is teaching an adult client with Type 1 diabetes that a primary cause of the development of diabetic ketoacidosis (DKA) is:

omitted meals.

a GI disturbance.

not taking insulin regularly.

an insulin overdosage.

Answer and Explanation

The Correct Answer is C

A.   While skipping meals can affect blood glucose levels, it is not a direct primary cause of DKA. In some cases, if a person with Type 1 diabetes skips a meal and does not adjust their insulin accordingly, it could lead to hyperglycemia. However, the absence of insulin is the critical factor in DKA.
B.   Gastrointestinal disturbances, such as vomiting or diarrhea, can contribute to DKA by leading to dehydration and altering insulin absorption. However, they are not primary causes. The main concern is that they may cause the individual to skip insulin or not manage their diabetes effectively.
C.   DKA is primarily caused by a lack of insulin, which leads to the body breaking down fat for energy instead of glucose. This process produces ketones, which can accumulate and lead to acidosis. For individuals with Type 1 diabetes, consistently taking insulin is crucial to prevent DKA.
D.   An insulin overdose can lead to hypoglycemia, not DKA. When too much insulin is taken, it can cause blood glucose levels to drop too low, which is the opposite of what occurs in DKA.

Correct Answer is A

Explanation

This is the expected peak time for regular insulin. After administration, the insulin will generally reach its maximum effectiveness in lowering blood glucose within this timeframe, making it essential for the client to monitor their blood sugar levels accordingly.

A. administer the PRN antianxiety medication. B. auscultate the client's breath sounds. C. elevate the head of the bed. D. prepare for mechanical ventilation.

Correct Answer is C

Explanation

A. While anxiety can exacerbate feelings of breathlessness, treating anxiety does not address the
underlying issue of respiratory distress. It is important to first stabilize the client’s respiratory condition
before managing anxiety.
B. Auscultating breath sounds can provide valuable information regarding the client’s respiratory status. However, in an emergency situation, immediate interventions to stabilize the client should take precedence over assessments, especially since the vital signs indicate significant distress.

C. Elevating the head of the bed can help improve respiratory effort by allowing better lung expansion and reducing the work of breathing. Given the client’s low oxygen saturation and signs of respiratory distress, this intervention can provide immediate relief and improve oxygenation.
D. While this may be necessary if the client's condition worsens or does not improve, it is not the first action to take. Preparing for mechanical ventilation is a more advanced intervention and should only occur after initial stabilization efforts have been made.
