A client has been brought to the emergency department by paramedics after being found unconscious. The client's Medic Alert bracelet indicates that the client has type 1 diabetes and the client's blood glucose is 22 mg/dL (1.2 mmol/L). The nurse should anticipate what intervention?
IV administration of 50% dextrose in water
IV bolus of 5% dextrose in 0.45% NaCI
Administer 4 oz. clear juice
Subcutaneous administration of 12 to 15 units of regular insulin
The Correct Answer is A
A. IV administration of 50% dextrose in water:
This is the correct answer. The client is severely hypoglycemic, and IV administration of 50% dextrose in water is the most rapid way to raise the blood glucose level in an emergency situation.
B. IV bolus of 5% dextrose in 0.45% NaCl:
While this solution contains dextrose, it is not as concentrated as 50% dextrose. In an emergency, a more concentrated solution is needed to rapidly correct severe hypoglycemia.
C. Administer 4 oz. clear juice:
Oral intake may be too slow in this critical situation. IV administration is more appropriate for rapidly raising the blood glucose level.
D. Subcutaneous administration of 12 to 15 units of regular insulin:
This would further lower the blood glucose level and is not appropriate for treating severe hypoglycemia.

Correct Answer is C
Explanation
A. Development of a buffalo hump and moon face:
This is associated with Cushing's syndrome, a disorder characterized by prolonged exposure to high levels of cortisol.
B. Central obesity and purple striations:
Also indicative of Cushing's syndrome, where excess cortisol can lead to the accumulation of fat in the abdominal area (central obesity) and the development of purple stretch marks (striae).
C. Sudden weight loss without dieting:
This is more characteristic of hyperthyroidism, where the thyroid gland is overactive, leading to increased metabolism and unintended weight loss.
D. Positive Trousseau's sign when checking the client's blood pressure:
Trousseau's sign is associated with hypocalcemia and is seen in conditions affecting the parathyroid gland rather than the thyroid. It involves carpal spasm induced by inflating a blood pressure cuff above the systolic pressure for a few minutes.
