An adolescent who was diagnosed with type 1 diabetes mellitus at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?
Skipped eating lunch.
Incorrectly administered too much insulin.
Had a cold and ear infection for the past two days.
Ate an extra peanut butter sandwich before gym class.
None
None
The Correct Answer is C
A. Skipped eating lunch would more likely cause hypoglycemia rather than diabetic ketoacidosis (DKA). When a person with type 1 diabetes skips a meal but still takes insulin, blood glucose levels drop, leading to hypoglycemia, not the elevated glucose and ketone production seen in DKA.
B. Incorrectly administered too much insulin would also result in hypoglycemia rather than DKA. Administering excessive insulin causes blood glucose levels to fall too low, which does not trigger the fat breakdown and ketone production that characterize DKA.
C. Had a cold and ear infection for the past two days is the most likely cause of diabetic ketoacidosis. Illness and infection cause the body to release stress hormones such as cortisol and adrenaline, which increase blood glucose levels and counteract insulin. In type 1 diabetes, insufficient insulin leads to hyperglycemia, fat breakdown for energy, and the production of ketones, resulting in DKA.
D. Ate an extra peanut butter sandwich before gym class would not cause DKA. Consuming extra food may raise blood glucose temporarily, but it would not lead to the severe insulin deficiency and ketone production seen in DKA, especially if the adolescent took insulin as prescribed.

Correct Answer is C
Explanation
A) Incorrect - Requesting the client to lie still may be relevant for certain assessments, but it is not specific to the situation described in the question.
B) Incorrect - Inquiring about episodes of sundowning is more relevant for clients with cognitive impairment and is not directly related to the client's weight loss and decreased energy and appetite.
C) Correct - Questioning the client about the frequency of falls is important, as falls can contribute to weight loss, decreased energy, and appetite changes in older adults.
D) Incorrect - Assisting the client with clarifying values about end-of-life care is a valuable nursing intervention but is not the priority in this assessment scenario.
Correct Answer is C
Explanation
Croup is a respiratory infection that causes inflammation and narrowing of the airway, resulting in a barking cough, hoarseness, and stridor. The PN should monitor the child's oxygen saturation level via pulse oximetry, as it can indicate the severity of the airway obstruction and the need for supplemental oxygen or other interventions.
