A nurse is collecting data from a client who takes metformin for type 2 diabetes. Which of the following medications is contraindicated for this client due its effect on blood glucose levels?

Cimetidine

Cephalexin

Prednisone

Levothyroxine

Answer and Explanation

The Correct Answer is C

A. Cimetidine:Cimetidine can indeed increase the effect of metformin due to competition for renal tubular clearance. This can lead to higher levels of metformin in the blood and potentially increase the risk of side effects. While it does not directly contraindicate metformin use, monitoring and dose adjustments might be necessary to manage this interaction.

B. Cephalexin:
Cephalexin is an antibiotic used to treat bacterial infections. It does not have a significant impact on blood glucose levels and is not contraindicated for a client taking metformin.

C. Prednisone:This is a corticosteroid that can increase blood glucose levels. Corticosteroids are known to cause hyperglycemia and may impair glucose control, which can be problematic for someone with diabetes taking metformin.

D. Levothyroxine:
Levothyroxine is a medication used to treat hypothyroidism. It does not have a direct impact on blood glucose levels and is not contraindicated for a client taking metformin.

Correct Answer is A

Explanation

A. Flush the tube with water:
This is the correct action to take first. Flushing the tube with water ensures that the tube is clear and functional before administering the bolus enteral feeding.

B. Measure stomach contents:
This is not the first action to take. Before measuring stomach contents, it's important to confirm that the tube is patent and clear by flushing it with water.

C. Elevate the head of the bed:
While elevating the head of the bed is important during and after enteral feedings to reduce the risk of aspiration, it is not the first step. The initial focus should be on verifying the tube's patency.

D. Return gastric content into the gastrostomy tube:
If there is resistance or difficulty flushing the tube, returning gastric contents into the tube may be necessary, but it's not the first action. The first step is to attempt to clear the tube with water.

A. Bradycardia B. Oliguria C. Peripheral edema D. Hypotension

Correct Answer is C

Explanation

A. Bradycardia:
Explanation: Bradycardia refers to a slow heart rate. In hypervolemia (fluid overload), the heart often compensates by increasing the heart rate rather than causing bradycardia.

B. Oliguria:
Explanation: Oliguria refers to decreased urine output. In hypervolemia, the increased fluid volume can lead to increased urine output rather than oliguria.

C. Peripheral Edema:
Explanation: Peripheral edema, or swelling in the extremities, is a common manifestation of hypervolemia. Excess fluid can accumulate in the tissues.

D. Hypotension:
Explanation: Hypertension, not hypotension, is more commonly associated with hypervolemia. The increased volume of fluid in the blood vessels can lead to elevated blood pressure.
