A nurse in a provider's office is caring for a child who has a history of asthma. Which of the following findings should the nurse report to the provider?

Choice A reason: A protective environment is a type of isolation precaution that is used for patients who are immunocompromised and at high risk of infection from environmental sources, such as fungi or bacteria. It involves using a private room with positive air pressure, high-efficiency particulate air (HEPA) filtration, and strict hand hygiene. It is not indicated for patients who have measles, as they are the source of infection, not the susceptible host.

Choice B reason: Airborne is a type of isolation precaution that is used for patients who have diseases that are transmitted by small droplets that can remain suspended in the air and travel over long distances, such as tuberculosis, chickenpox, or measles. It involves using a private room with negative air pressure, HEPA filtration, and respiratory protection for health care workers and visitors. It is the appropriate isolation precaution for patients who have measles, as it prevents the spread of the virus to others.

Choice C reason: Contact is a type of isolation precaution that is used for patients who have diseases that are transmitted by direct or indirect contact with the patient or their environment, such as Clostridioides difficile, scabies, or impetigo. It involves using a private room or cohorting with similar patients, wearing gloves and gowns, and using dedicated equipment. It is not indicated for patients who have measles, as the disease is not spread by contact.

Choice D reason: Droplet is a type of isolation precaution that is used for patients who have diseases that are transmitted by large droplets that are generated by coughing, sneezing, or talking, such as influenza, pertussis, or meningitis. It involves using a private room or cohorting with similar patients, wearing a surgical mask, and maintaining a distance of at least 3 feet from the patient. It is not indicated for patients who have measles, as the disease is spread by airborne transmission.

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.
