A nurse is caring for an adolescent who has been diagnosed with diabetic ketoacidosis (DKA). The nurse notes the following:
When planning care for this client, the nurse should anticipate a provider's prescription for which of the following?
Insulin therapy and fluid replacement
Glucagon injection and potassium supplements
Bicarbonate infusion and sodium restriction
Dextrose infusion and diuretics
The Correct Answer is A
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.

Correct Answer is D
Explanation
Choice A reason: Maintaining the infant in the supine position is not an appropriate intervention, as it can increase the pressure on the myelomeningocele sac and cause further damage to the spinal cord. The nurse should position the infant prone or side-lying, with the head turned to one side and the hips flexed.
Choice B reason: Limiting visitors to immediate family members is not a necessary intervention, as the infant does not have an infectious condition that requires isolation. The nurse should encourage the parents and other family members to visit and bond with the infant, and provide emotional support and education.
Choice C reason: Initiating contact precautions is not a required intervention, as the infant does not have a contagious condition that poses a risk of transmission to others. The nurse should follow standard precautions, such as washing hands, wearing gloves, and disposing of contaminated materials properly.
Choice D reason: Providing a latex-free environment is an essential intervention, as the infant has a high risk of developing a latex allergy due to the frequent exposure to latex products during surgery and other procedures. The nurse should avoid using latex gloves, catheters, syringes, bandages, or other items that contain latex, and use alternative materials instead. The nurse should also label the infant's chart, crib, and door with a latex allergy alert.
Correct Answer is D
Explanation
Choice A reason: This is not a correct description of Bryant traction. This type of traction does not involve pins or wires inserted into the bone. It is a skin traction that uses adhesive straps or bandages attached to the skin of the lower legs.
Choice B reason: This is not a correct description of Bryant traction. This type of traction does not maintain the leg in an extended position. It flexes the hip and knee at a 90-degree angle and suspends the leg in the air.
Choice C reason: This is not a correct description of Bryant traction. This type of traction does not use a sling under the knee of the affected leg. It uses a spreader bar to keep the legs apart and prevent rotation.
Choice D reason: This is a correct description of Bryant traction. This type of traction elevates the buttocks slightly off of the bed to provide countertraction and alignment of the fractured bone.
