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
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 D
Explanation
A. Crackles throughout both lung fields:
Crackles in the lung fields could indicate fluid overload, which is a concern. However, in the context of treating hyponatremia with hypertonic saline, it might not be an immediate adverse effect related to the saline infusion itself.
B. Radial pulse of 105 beats/min:
An increase in heart rate can be associated with hypertonic saline infusion. It might be expected due to the osmotic effects of the saline.
C. Sediment and blood in the urine:
Sediment and blood in the urine could be indicative of kidney damage or injury. This is not a typical side effect of hypertonic saline infusion for hyponatremia.
D. Blood pressure increases from 88/50 to 122/74 mmHg:
A significant increase in blood pressure can be an adverse effect of hypertonic saline. Rapid correction of hyponatremia can lead to osmotic demyelination syndrome, which can manifest with neurological symptoms and changes in blood pressure.
Correct Answer is D
Explanation
A. Report of decreased urinary output
Explanation: Decreased urinary output is not typically associated with hyperglycemia. In fact, increased urinary output (polyuria) is more characteristic.
B. Random blood glucose 126 mg/dL
Explanation: This level is within the normal range for random blood glucose. Hyperglycemia is usually defined by higher blood glucose levels.
C. Clammy skin
Explanation: Clammy skin is not a direct manifestation of hyperglycemia. Symptoms of hyperglycemia may include increased thirst, frequent urination, and blurred vision.
D. History of poor wound healing
Explanation: This is correct. Hyperglycemia can contribute to impaired wound healing, as it affects the body's ability to repair tissues.
