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 C

Explanation

A. Abrasion:
This type of wound occurs when the skin rubs or scrapes against a rough surface. It's often referred to as a "scrape" and typically involves superficial damage to the skin without penetration or tearing.

B. Contusion:
Commonly known as a bruise, a contusion results from blunt trauma to the body, causing blood vessels to break and leak blood into the surrounding tissues. The skin remains intact, but there's discoloration due to the blood.

C. Laceration:
This type of wound involves a tear or irregular cut in the skin, often with jagged or rough edges. Lacerations typically result from sharp or blunt trauma that causes the skin to tear.

D. Puncture:
Puncture wounds occur when a sharp object pierces the skin and underlying tissues, creating a small, deep hole. These wounds might not bleed much externally but can cause damage to internal structures and carry a risk of infection due to the depth and possible trapping of debris.

A. "My appetite will be decreased." B. "I might experience blurry vision at times." C. "My breath may have a fruity odor." D. "I will be more thirsty than usual."

Correct Answer is D

Explanation

A. "My appetite will be decreased."
Explanation: Hyperglycemia is often associated with increased appetite rather than decreased appetite.

B. "I might experience blurry vision at times."
Explanation: This is correct. Blurry vision can be a symptom of hyperglycemia due to changes in the fluid levels in the eye caused by high blood sugar.

C. "My breath may have a fruity odor."
Explanation: Fruity breath odor is associated with diabetic ketoacidosis (DKA), which is a severe complication of diabetes. It occurs due to the production of ketones during uncontrolled diabetes, leading to this distinct odor. While it's related to high blood sugar, it's more specifically linked to DKA.

D. "I will be more thirsty than usual."
Explanation: Increased thirst is a classic symptom of hyperglycemia. When blood sugar levels are high, the body tries to flush out the excess sugar through increased urination, leading to dehydration and subsequently increased thirst.
