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: Subcutaneous insulin is not the preferred route for a client with DKA, as it has a slower onset and peak than IV insulin. IV regular insulin is the preferred route, as it provides a rapid and continuous infusion of insulin that can be titrated according to the blood glucose level.

Choice B reason: IV regular insulin is the medication of choice for a client with DKA, as it lowers the blood glucose level and reverses the ketosis and acidosis. IV regular insulin has a rapid onset and peak, and can be adjusted based on the client's response.

Choice C reason: IV potassium chloride is indicated for a client with DKA, as the client is at risk of hypokalemia due to osmotic diuresis, insulin therapy, and metabolic acidosis. IV potassium chloride can prevent or treat hypokalemia and its complications, such as cardiac arrhythmias.

Choice D reason: Oxygen via nasal cannula is not necessary for a client with DKA, unless the client has signs of hypoxia or respiratory distress. The client's deep and rapid respirations are a compensatory mechanism for the metabolic acidosis, and do not indicate a need for oxygen therapy.

Choice E reason: Sodium bicarbonate is not recommended for a client with DKA, as it can cause paradoxical cerebral acidosis, hypokalemia, and impaired oxygen delivery. The client's acidosis can be corrected by IV insulin and fluid therapy, which will restore the normal metabolism of glucose and ketones.

Choice A reason: Placing the client in a private room is not necessary for a client who has a high WBC count, unless they have other indications for isolation, such as an infectious disease. A high WBC count may indicate inflammation, infection, or other conditions that affect the immune system.

Choice B reason: Monitoring the client's temperature every 4 hr is an appropriate action for a nurse to take for a client who has a high WBC count. A fever is a common sign of infection or inflammation, and it may require further intervention, such as antibiotics or antipyretics.

Choice C reason: Administering an antihistamine as prescribed is not related to a high WBC count. Antihistamines are used to treat allergic reactions, which may cause a low WBC count due to the release of histamine from mast cells.

Choice D reason: Encouraging the client to increase fluid intake is not specific to a high WBC count. Fluid intake should be based on the client's hydration status, urine output, and other factors. Increasing fluid intake may help flush out toxins or bacteria, but it is not a priority action for a client who has a high WBC count.
