A nurse is caring for a client who was involuntarily committed to a mental health facility. Which of the following is a client's legal right?

A. Negative urine ketones: Diabetic ketoacidosis (DKA) is characterized by increased production of ketone bodies due to insulin deficiency and enhanced lipolysis. Ketones accumulate in the blood and spill into the urine, producing positive urine ketone results. The absence of urine ketones does not support the presence of ketoacidosis, as ketosis is a defining metabolic feature.

B. Kussmaul respirations: Kussmaul respirations are deep, rapid breathing patterns that occur as a compensatory response to metabolic acidosis. In DKA, excess ketone production leads to accumulation of hydrogen ions and decreased serum bicarbonate. The respiratory system compensates by increasing ventilation to eliminate carbon dioxide.

C. Hypoglycemia: DKA is associated with hyperglycemia due to insufficient insulin, which prevents glucose from entering cells and leads to elevated serum glucose levels. Hypoglycemia involves low blood glucose and does not trigger the ketone overproduction seen in DKA. The pathophysiology of DKA centers on insulin deficiency and high circulating glucose.

D. Hypertension: Clients with DKA often experience osmotic diuresis from severe hyperglycemia, leading to dehydration and volume depletion. This intravascular fluid loss more commonly results in hypotension rather than elevated blood pressure. The hemodynamic changes in DKA are primarily related to dehydration and electrolyte imbalance.

A. Prednisolone: Corticosteroids like prednisolone are not contraindicated with fluoxetine. Although concurrent use may slightly increase the risk of gastrointestinal irritation or affect blood glucose levels, there is no major drug interaction that prevents their coadministration.

B. Lispro: Lispro is a rapid-acting insulin used for diabetes management. Fluoxetine does not directly contraindicate insulin use, though it may slightly affect glycemic control in some clients. Close monitoring of blood glucose is recommended, but the combination is generally safe.

C. Calcitonin: Calcitonin, used for conditions like osteoporosis, does not have significant interactions with fluoxetine. There is no contraindication for concurrent use, and standard monitoring is sufficient.

D. Phenelzine: Phenelzine is a monoamine oxidase inhibitor (MAOI). Combining MAOIs with fluoxetine, a selective serotonin reuptake inhibitor (SSRI), can precipitate serotonin syndrome, a potentially life-threatening condition characterized by confusion, hyperthermia, autonomic instability, and neuromuscular abnormalities. Concurrent use is strictly contraindicated.
