A nurse in an emergency department is caring for a client who has a compound fracture of the right tibia. Which of the following actions should the nurse take?

A) Evaluate the client's understanding of diabetes management: While it is important to assess the client’s understanding of diabetes management to prevent future hyperglycemic episodes, this is not the immediate priority. The client's current hyperglycemic-hyperosmolar state needs urgent intervention to stabilize their condition before educational measures can be effective.

B) Administer potassium supplements: Potassium supplementation may be necessary, especially if the client is hypokalemic, but it is not the first action. Electrolyte levels should be monitored and corrected as part of the treatment, but the initial priority is to address the severe dehydration and hyperglycemia.

C) Initiate a continuous infusion of 0.9% sodium chloride: This is the most critical first step. Clients in a hyperglycemic-hyperosmolar state are typically severely dehydrated due to osmotic diuresis. Initiating a continuous infusion of isotonic saline helps to restore intravascular volume, improve perfusion, and stabilize hemodynamics, which is essential before addressing other issues.

D) Check for improvements in the client's level of consciousness: Monitoring the client's level of consciousness is important as it provides information about their neurological status and response to treatment. However, this is a subsequent action after initiating fluid resuscitation, which directly addresses the immediate life-threatening aspects of the hyperglycemic-hyperosmolar state.

A) "Switch from breastfeeding to formula feeding when your baby is 2 months old": Breastfeeding is associated with a reduced risk of otitis media, as breast milk contains antibodies and other factors that help protect against infections. Switching to formula feeding may not reduce the incidence of otitis media and can potentially increase the risk.

B) "Avoid exposing your baby to secondhand smoke": Exposure to secondhand smoke is a significant risk factor for otitis media. Smoke irritates the respiratory tract and can lead to inflammation and fluid accumulation in the middle ear, increasing the likelihood of ear infections. Avoiding secondhand smoke can help reduce the incidence of otitis media.

C) "Ensure your baby receives the Hepatitis B vaccine": While the Hepatitis B vaccine is important for preventing Hepatitis B infection, it does not have a direct impact on the incidence of otitis media. The vaccine’s primary role is in preventing liver disease rather than ear infections.

D) "Place your baby in a supine position during feeding": Placing a baby in a supine position (lying on their back) during feeding does not reduce the risk of otitis media. In fact, feeding a baby while lying flat can increase the risk of ear infections as it may cause milk to flow into the middle ear. It is generally recommended to hold the baby in an upright or semi-upright position during feeding.
