A nurse is caring for a child who has red marks across his cheeks. Which of the following actions should the nurse take?

Choice A reason: Continuing to monitor the client is not the best action, as it does not address the low urine output of the child. The child has a urine output of 20 mL/hr, which is below the expected range of 30 to 40 mL/hr for a 3-year-old child. Low urine output can indicate dehydration, kidney injury, or urinary tract obstruction, which require prompt intervention.

Choice B reason: Performing a bladder scan at the bedside is not the most appropriate action, as it is not the first-line diagnostic tool for low urine output. A bladder scan is a noninvasive ultrasound device that measures the amount of urine in the bladder. It can help detect urinary retention, which is the inability to empty the bladder completely. However, urinary retention is unlikely in a 3-year-old child, and a bladder scan may not be accurate or reliable in children.

Choice C reason: Providing oral rehydration fluids is the best action, as it can help restore the fluid and electrolyte balance of the child. Oral rehydration fluids are solutions that contain water, sugar, and salt in specific proportions that match the body's needs. They can prevent or treat dehydration, which is a common cause of low urine output in children. The nurse should offer the child oral rehydration fluids every 15 to 20 minutes, and monitor the urine output, vital signs, and hydration status.

Choice D reason: Notifying the provider is not the first action, as it is not the most urgent or effective intervention for low urine output. The nurse should notify the provider after providing oral rehydration fluids and assessing the child's response. The nurse should also report any signs or symptoms of dehydration, such as dry mucous membranes, sunken eyes, poor skin turgor, or lethargy. The provider may order further tests or treatments, such as blood tests, urine tests, or intravenous fluids.

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.
