The nurse is assessing an adolescent female diagnosed with anorexia nervosa who is admitted to the unit with severe malnutrition and electrolyte imbalance.
Which pathological process results from the adolescent's consistent maladaptive behavior?

The correct answers are Choices B, C, D, and E.

Choice A rationale: Dentures should remain in place to preserve facial structure and dignity. Removing them may cause facial collapse, distressing the family during viewing and violating postmortem presentation standards.

Choice B rationale: Gently closing the eyes prevents ocular drying and maintains a peaceful appearance. If eyelids resist closure, moistened cotton balls may be used temporarily to assist with natural positioning.

Choice C rationale: Placing a small pillow under the head elevates it, preventing blood pooling and facial discoloration due to livor mortis. It supports a natural, respectful presentation for family viewing.

Choice D rationale: Applying a body shroud ensures hygienic containment and visual dignity. It’s standard practice before transport and aligns with institutional protocols for respectful postmortem care.

Choice E rationale: Removing resuscitation equipment reduces trauma triggers for the family, restores environmental calm, and supports emotional closure. It also complies with facility standards for postmortem room preparation.

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 rise1. 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.
