A client diagnosed with type 1 diabetes mellitus reports a sudden onset of tremors and paleness. What is the best immediate action by the nurse?

The best immediate action in this scenario is to provide the client with a source of quick-acting carbohydrates, such as 4 oz. of orange juice. This is crucial because the client is exhibiting signs of hypoglycemia, which include tremors and paleness. When a person with type 1 diabetes experiences low blood sugar levels, consuming fast-acting carbohydrates helps to rapidly elevate their blood glucose levels, alleviating the symptoms of hypoglycemia.

In cases of mild to moderate hypoglycemia, oral intake of carbohydrates is typically the first line of treatment. Orange juice is effective because it is readily absorbable and quickly increases blood sugar levels. It's important to monitor the patient after administering the juice to ensure the blood sugar levels rise appropriately.

The action of checking when the last dose of insulin was given is useful for understanding the context of hypoglycemia but is not an immediate need and won't address the current urgent situation. Administering 50% dextrose IV would be an appropriate response if the client were unconscious or unable to swallow, but since the patient is conscious and able to take oral fluids, this is not the best first step. Finally, reassessing the blood glucose level in 15 minutes is important for monitoring, but it should
