The diabetic ketoacidosis associated with insulin deficiency is related to:
Extracellular hyperglycemia
Hypoglycemia
Use of fat and protein as an energy source
Increased cellular metabolism of glucose
The Correct Answer is C
Choice A reason:
Extracellular hyperglycemia refers to high blood sugar levels outside the cells. While hyperglycemia is a common feature of diabetic ketoacidosis (DKA), it is not the direct cause of the condition. DKA occurs when the body cannot use glucose for energy due to a lack of insulin, leading to the breakdown of fat and protein for energy, which produces ketones and causes acidosis.
Choice B Reason:
Hypoglycemia, or low blood sugar, is not associated with diabetic ketoacidosis. In fact, DKA is characterized by high blood sugar levels. Hypoglycemia is a separate condition that can occur in individuals with diabetes, particularly if they take too much insulin or skip meals.
Choice C Reason:
The use of fat and protein as an energy source is the primary mechanism behind diabetic ketoacidosis. When insulin is deficient, the body cannot utilize glucose for energy. As a result, it breaks down fat and protein to produce energy. This process generates ketones, which are acidic and lead to the development of ketoacidosis.
Choice D Reason:
Increased cellular metabolism of glucose is not related to diabetic ketoacidosis. In DKA, the problem is that cells cannot use glucose effectively due to a lack of insulin. Instead, the body resorts to breaking down fat and protein for energy, leading to the production of ketones and acidosis.

Correct Answer is C
Explanation
Choice A reason:
Foster self-care activities: Encouraging self-care activities is important for children with hemiplegic cerebral palsy as it promotes independence and self-esteem. However, it is not the highest priority compared to ensuring the child’s safety and accessibility in their home environment.
Choice B Reason:
Improve the child’s communication skills: Enhancing communication skills is crucial for the child’s social and emotional development. Effective communication can significantly improve the child’s quality of life. However, while important, it is not the most immediate priority compared to modifying the home environment for safety.
Choice C Reason:
Modify the home environment for safety and accessibility: Ensuring the home environment is safe and accessible is the top priority. Children with hemiplegic cerebral palsy may have mobility challenges, and a safe environment can prevent injuries and promote independence. This modification directly impacts the child’s daily life and overall well-being.
Choice D Reason:
Provide respite services for the parents: Offering respite services is beneficial for the parents’ mental and emotional health, allowing them to take breaks and recharge. While this is important, it is not the primary concern compared to the child’s immediate safety and accessibility needs.
Correct Answer is C
Explanation
Choice A reason:
Performing an ultrasound to determine if there is urinary retention is not the immediate priority action. While an ultrasound can help assess urinary retention, the presence of edema, redness, and the foreskin being behind the glans penis suggests a condition known as paraphimosis. Paraphimosis is a medical emergency that requires prompt attention to prevent complications such as tissue damage. Therefore, alerting the ER physician is the priority action.
Choice B reason:
Asking the parents specifically how long the infant has not voided is important for gathering information, but it is not the immediate priority action. The clinical signs of edema, redness, and the foreskin being behind the glans penis indicate a potential emergency that requires immediate medical intervention. While obtaining a detailed history is important, the nurse should first alert the ER physician to ensure timely management.
Choice C reason:
Alerting the ER physician to the patient’s condition is the correct priority action. The presence of edema, redness, and the foreskin being behind the glans penis suggests paraphimosis, which is a urological emergency. Prompt intervention is necessary to reduce the foreskin and restore normal blood flow to prevent tissue damage3. The ER physician can provide the necessary treatment and management for this condition.
Choice D reason:
Continuing to monitor the patient in the ER setting is not appropriate without first addressing the potential emergency. The signs of edema, redness, and the foreskin being behind the glans penis indicate a condition that requires immediate medical attention. Monitoring alone is insufficient; the nurse must alert the ER physician to ensure prompt intervention.
