The nurse is educating a student on moderate/conscious sedation. Which of the following is a correct statement about moderate sedation?

A. Glucagon IM:
Glucagon is used to treat hypoglycemia (low blood sugar), not hyperglycemia. It is typically administered intramuscularly in cases of severe hypoglycemia to rapidly raise blood glucose levels. In acute hyperglycemia, the blood glucose is already elevated, so glucagon is not appropriate. The correct treatment for hyperglycemia includes insulin administration, fluid replacement, and monitoring of electrolytes.

B. Regular insulin IV infusion:
In acute hyperglycemia, particularly in cases of diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS), regular insulin is commonly administered intravenously to reduce blood glucose levels. It acts rapidly to lower blood glucose, and the dose can be adjusted based on the client's response. Therefore, this is an expected intervention in the management of acute hyperglycemia.

C. Potassium laboratory monitoring:
In acute hyperglycemia, particularly during insulin administration, potassium levels should be closely monitored. Insulin can drive potassium into cells, potentially leading to hypokalemia (low potassium levels). Since hyperglycemia treatment can alter electrolyte balance, potassium levels need to be frequently checked to avoid complications like arrhythmias or muscle weakness. This is an important intervention in managing hyperglycemia.

D. IV fluid replacement:
IV fluid replacement is a crucial part of managing acute hyperglycemia, particularly in conditions like DKA and HHS. These conditions cause dehydration due to osmotic diuresis, and fluid replacement helps to restore normal hydration status and support renal function. The nurse would expect IV fluid administration to correct electrolyte imbalances and improve circulatory volume.

A) "Administer IV hydralazine and monitor blood pressure":
. The patient's elevated blood pressure (172/92 mmHg), along with headaches and blurred vision, could indicate a hypertensive emergency, a serious condition where extremely high blood pressure can cause acute organ damage. Hydralazine is a common intravenous antihypertensive medication used to lower blood pressure quickly in these situations. The nurse should administer hydralazine as prescribed and closely monitor the blood pressure to prevent complications like stroke, heart failure, or kidney damage. Blood pressure management is the priority, as the patient's symptoms are likely related to the elevated BP.

B) "Administer oxygen at 10 liters/minute by non-rebreather mask":
. While oxygen therapy may be appropriate for patients with respiratory distress or hypoxia, the patient's SpO2 is 97% on room air, indicating that there is no immediate oxygenation issue. Administering oxygen unnecessarily could lead to oxygen toxicity, and it is not the priority in this case. The patient's main concern is their elevated blood pressure, which requires urgent management.

C) "Administer acetaminophen 650 mg PO re-check temperature":
. While headaches are one of the patient's complaints, there is no indication of fever (the temperature is 98.6°F). Administering acetaminophen would be appropriate for pain relief, but it is not the priority in this case. The elevated blood pressure and potential hypertensive emergency are the primary issues that need to be addressed first.

D) "Infuse 0.9% sodium chloride at 120 mL/hour":
. Normal saline (0.9% sodium chloride) is typically used for hydration, but there is no indication that the patient is dehydrated or that intravenous fluids are the priority. In cases of hypertensive emergency, the goal is to lower blood pressure using antihypertensive medications, not to infuse fluids. Fluid administration could potentially worsen the situation if the elevated blood pressure is not addressed first.
