A patient asks how metformin works to control blood sugar. What is the nurse's best response?

"Metformin stimulates the pancreas to produce more insulin."

"Metformin increases the absorption of glucose in the intestines."

"Metformin decreases glucose production in the liver and improves insulin sensitivity."

"Metformin decreases the breakdown of fat in the body."

Answer and Explanation

The Correct Answer is C

A. Metformin does not stimulate the pancreas to produce more insulin; that action is characteristic of sulfonylureas.

B. Metformin does not increase the absorption of glucose in the intestines; rather, it works by reducing the amount of glucose released into the bloodstream.

C. Metformin primarily decreases glucose production in the liver and improves insulin sensitivity in peripheral tissues, which helps lower blood sugar levels. This makes it effective for managing type 2 diabetes.

D. While metformin can have effects on fat metabolism, its primary action is not to decrease fat breakdown but to manage blood glucose levels.

Correct Answer is D

Explanation

A. Sodium levels are important to monitor, but they are not the primary concern with furosemide treatment.

B. Bone marrow function is not a direct concern related to furosemide therapy.

C. Calcium levels are less critical compared to potassium when monitoring a client on furosemide.

D. Potassium levels are correct because furosemide is a loop diuretic that can lead to significant potassium loss, putting the client at risk for hypokalemia, which can have serious cardiac implications.

A. 7 doses B. 5 doses C. 20 doses D. 12 doses

Correct Answer is C

Explanation

Total volume (mL) / Dose volume (mL) = Number of doses

First, we need to find the dose volume. Since the strength is 350 mg/5 mL, a single dose of 350 mg would require 5 mL.

Now, we can plug in the values into the formula:

100 mL / 5 mL/dose = 20 doses
