Nursing Fundamentals Oxygenation Questions Questions
Question 1 of 5
A nurse is caring for a patient with a history of diabetes who is experiencing dizziness and lightheadedness. What is the priority action?
Correct Answer: B
Rationale: The correct answer is B: Administer glucose for hypoglycemia. In a patient with a history of diabetes experiencing dizziness and lightheadedness, the priority action is to address hypoglycemia, which can be life-threatening if left untreated. Administering glucose will help raise the blood sugar levels quickly and resolve the symptoms. Administering insulin (choices A and C) would lower blood sugar levels further, worsening the symptoms. Choice D, administering glucose for hypoglycemia, is incorrect because giving additional glucose to a patient already experiencing hypoglycemia can lead to rebound hypoglycemia. Thus, the priority is to treat hypoglycemia promptly with glucose.
