A nurse is caring for a client who had an evacuation of a subdural hematoma. Which of the following actions should the nurse take first?

Choice A Reason: This choice is incorrect because administering intravenous pain medication is not the priority action for a client who has sustained partial-thickness burns. Pain medication may be indicated for pain relief and comfort, but it does not address the potential life-threatening complications of burns such as shock, infection, or respiratory distress.

Choice B Reason: This choice is incorrect because drawing blood for a CBC count is not the priority action for a client who has sustained partial-thickness burns. A CBC count may be useful to monitor the hematological status and detect any signs of infection or anemia, but it does not address the immediate needs of the client

Choice C Reason: This choice is incorrect because inserting an indwelling urinary catheter is not the priority action for a client who has sustained partial-thickness burns. A urinary catheter may be necessary to measure the urine output and assess the renal function and fluid balance, but it does not address the most urgent problem of the client.

Choice D Reason: This choice is correct because inspecting the mouth for signs of inhalation injuries is the priority action for a client who has sustained partial-thickness burns. Inhalation injuries are caused by inhaling hot air, smoke, or toxic gases that damage the airway and lungs. They can cause airway obstruction, bronchospasm, pulmonary edema, or respiratory failure. Therefore, the nurse should inspect the mouth for signs such as soot, singed nasal hairs, burns on the lips or tongue, hoarseness, stridor, or wheezes. The nurse should also monitor the oxygen saturation and arterial blood gases to assess the oxygenation and ventilation status of the client.

Choice A Reason: This choice is incorrect because oral hypoglycemic medications are not effective for treating DKA. Oral hypoglycemic medications are drugs that lower the blood glucose level by stimulating insulin secretion or increasing insulin sensitivity. They may be used for clients who have type 2 diabetes mellitus, but they do not work for clients who have type 1 diabetes mellitus or DKA.

Choice B Reason: This choice is correct because 0.9% sodium chloride IV bolus is an effective treatment for DKA. 0.9% sodium chloride is an isotonic solution that contains the same concentration of solutes as blood plasma. It may be used for clients who have fluid loss, dehydration, or shock. In DKA, the body breaks down fat for energy due to insulin deficiency or resistance, resulting in high levels of ketones and acids in the blood. This causes osmotic diuresis, dehydration, electrolyte imbalance, and metabolic acidosis. Therefore, administering 0.9% sodium chloride IV bolus can help to restore fluid volume and correct electrolyte imbalance.

Choice C Reason: This choice is incorrect because dextrose 5% in 0.45% sodium chloride is not indicated for treating DKA. Dextrose 5% in 0.45% sodium chloride is a hypertonic solution that contains more solutes than blood plasma. It may be used for clients who have hyponatremia, cerebral edema, or malnutrition, but it can worsen hyperglycemia and osmotic diuresis in clients who have DKA.

Choice D Reason: This choice is incorrect because glucocorticoid medications are not indicated for treating DKA. Glucocorticoid medications are drugs that mimic the effects of cortisol, a hormone that regulates stress response and inflammation. They may be used for clients who have allergic reactions, asthma, or autoimmune diseases, but they can increase blood glucose levels and inhibit insulin action in clients who have DKA.
