A nurse in a provider's office is caring for an infant who has developmental dysplasia of the hip (DDH). The nurse should include which of the following instructions when teaching the parents about the Pavlik harness?

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.

Choice A reason: Tetany is not a typical finding in an infant who is dehydrated. Tetany is a condition where the muscles contract involuntarily and cause spasms or cramps. It is usually caused by low calcium levels or alkalosis, not dehydration.

Choice B reason: Slow, bounding pulse is not a typical finding in an infant who is dehydrated. A slow, bounding pulse may indicate increased intracranial pressure or heart failure, not dehydration. A fast, weak pulse is more likely to occur in an infant who is dehydrated.

Choice C reason: Decreased temperature is not a typical finding in an infant who is dehydrated. A decreased temperature may indicate hypothermia or sepsis, not dehydration. A normal or slightly elevated temperature is more likely to occur in an infant who is dehydrated.

Choice D reason: Irritability is a typical finding in an infant who is dehydrated. Irritability indicates that the infant is uncomfortable and thirsty. It may also be a sign of cerebral dehydration, which can affect the infant's mental status and behavior.
