A nurse is providing teaching to an adolescent who has type 1 diabetes mellitus. Which of the following should the nurse include in the teaching?

Choice A reason: Asking the parents what caused the bruises is not the best action, as it may not elicit truthful or accurate information. The parents may be the perpetrators of the abuse, or they may be unaware or in denial of the abuse. The nurse should not confront or accuse the parents without sufficient evidence or support.

Choice B reason: Notifying social services is an important action, but not the first one. The nurse should first gather more information and document the findings before making a report. The nurse should also follow the policies and procedures of the health care facility regarding child abuse reporting.

Choice C reason: Asking the toddler what caused the bruises is the best action, as it may provide valuable clues about the source and nature of the injuries. The nurse should use a gentle and nonjudgmental approach, and ask open-ended questions, such as "How did you get these bruises?" or "Who hurt you?" The nurse should also observe the child's behavior and body language, and reassure the child that they are not in trouble.

Choice D reason: Notifying the provider is a necessary action, but not the first one. The nurse should first assess and interview the child, and document the findings. The nurse should also consult with the provider about the appropriate medical care and follow-up for the child. The provider may also assist the nurse in making a report to social services.

Choice A reason: Insulin therapy and fluid replacement are the main treatments for DKA, as they lower the blood glucose level and correct the dehydration and electrolyte imbalance caused by osmotic diuresis and acidosis.

Choice B reason: Glucagon injection and potassium supplements are not indicated for DKA, as they may worsen the hyperglycemia and the hyperkalemia. Glucagon stimulates the liver to release more glucose into the bloodstream, while potassium supplements may increase the risk of cardiac arrhythmias.

Choice C reason: Bicarbonate infusion and sodium restriction are not the first-line treatments for DKA, as they may have adverse effects on the acid-base balance and the fluid status. Bicarbonate infusion may cause paradoxical cerebral acidosis and hypokalemia, while sodium restriction may exacerbate the hyponatremia and the hypovolemia.

Choice D reason: Dextrose infusion and diuretics are contraindicated for DKA, as they may increase the blood glucose level and the dehydration. Dextrose infusion may trigger a rebound hyperglycemia, while diuretics may cause further fluid and electrolyte loss.
