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 C
Explanation
Choice A reason: This is not a correct instruction for the nurse to include in the teaching plan. The parents should not adjust the length of the straps of the Pavlik harness by themselves, as this may affect the position and stability of the infant's hips. The nurse should instruct the parents to bring the infant to the provider's office regularly for check-ups and adjustments of the harness.
Choice B reason: This is not a correct instruction for the nurse to include in the teaching plan. The parents should not breastfeed the infant while wearing the harness, as this may interfere with the proper alignment and function of the harness. The nurse should instruct the parents to remove the harness before breastfeeding the infant, and to reapply it after feeding.
Choice C reason: This is a correct instruction for the nurse to include in the teaching plan. The parents should place the diaper under the straps of the harness, as this prevents the diaper from interfering with the position and function of the harness. The nurse should instruct the parents to change the diaper frequently and to avoid using bulky or cloth diapers.
Choice D reason: This is not a correct instruction for the nurse to include in the teaching plan. The parents should not remove the harness when bathing the infant, as this may interrupt the treatment and cause complications. The nurse should instruct the parents to sponge bathe the infant while wearing the harness, and to keep the harness clean and dry.
Correct Answer is D
Explanation
Choice A reason: Herpes simplex is a viral infection that causes painful blisters or ulcers in the mouth or on the lips. It does not cause a white, milky plaque that does not come off with rubbing.
Choice B reason: Dermatitis is a skin inflammation that causes redness, itching, and scaling. It does not affect the mouth or cause a white, milky plaque that does not come off with rubbing.
Choice C reason: Squamous cell carcinoma is a type of skin cancer that develops from the squamous cells that line the mouth and other parts of the body. It causes a hard, irregular, or ulcerated growth that may bleed or become infected. It does not cause a white, milky plaque that does not come off with rubbing.
Choice D reason: Candidiasis, also known as oral thrush, is a fungal infection that causes a white, milky plaque that coats the tongue, cheeks, and roof of the mouth. It can be scraped off, but may leave a red, sore, or bleeding surface. It is more common in people who have a weakened immune system, such as those who take antibiotics, immunosuppressants, or corticosteroids. It can also be triggered by smoking, dry mouth, or poor oral hygiene.
