Blood glucose 98 mg/dL

BUN 18 mg/dL

Hemoglobin 8.6 g/dL

Potassium 3.5 mEq/L

Answer and Explanation

The Correct Answer is C

Choice A: This is incorrect because blood glucose 98 mg/dL is within the normal range of 70 to 110 mg/dL. The nurse does not need to notify the provider for this value.

Choice B: This is incorrect because BUN 18 mg/dL is within the normal range of 10 to 20 mg/dL. The nurse does not need to notify the provider for this value.

Choice C: This is correct because hemoglobin 8.6 g/dL is below the normal range of 12 to 18 g/dL. The nurse should notify the provider for this value as it indicates anemia, which can be caused by blood loss during surgery or impaired bone marrow function.

Choice D: This is incorrect because potassium 3.5 mEq/L is within the normal range of 3.5 to 5.0 mEq/L. The nurse does not need to notify the provider for this value.

Correct Answer is ["1.5"]

Explanation

The correct answer is 1.5 mL. Here is the explanation:

To calculate the amount of mL to administer, the nurse should use the following formula:

mL = (units ordered / units available) x mL available

Plugging in the values from the question, we get:

mL = (15,000 / 10,000) x 1

mL = 1.5 x 1

mL = 1.5

Therefore, the nurse should administer 1.5 mL of heparin with each dose.

A. Vegetable shortening B. Lard C. Canola oil D. Butter

Correct Answer is C

Explanation

Choice A: This is incorrect. Vegetable shortening is high in saturated fat and trans fat, which can increase the risk of cardiovascular disease by raising the LDL (bad) cholesterol and lowering the HDL (good) cholesterol.

Choice B: This is incorrect. Lard is animal fat that is high in saturated fat and cholesterol, which can also increase the risk of cardiovascular disease by raising the LDL cholesterol and lowering the HDL cholesterol.

Choice C: This is correct. Canola oil is low in saturated fat and high in monounsaturated fat and omega-3 fatty acids, which can lower the risk of cardiovascular disease by lowering the LDL cholesterol and raising the HDL cholesterol.

Choice D: This is incorrect. Butter is dairy fat that is high in saturated fat and cholesterol, which can also increase the risk of cardiovascular disease by raising the LDL cholesterol and lowering the HDL cholesterol
