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 C
Explanation
A. Apply Neosporin to avoid infection:
This choice suggests applying Neosporin to the surgical site. However, the immediate postoperative care for cleft lip surgery often involves keeping the incision site covered with sterile dressings. Topical antibiotics may be prescribed by the healthcare provider if deemed necessary, but it's not a routine application without specific instructions.
B. Apply elbow immobilizers when not being held:
This choice implies using elbow immobilizers for the child. However, elbow immobilizers are not a standard intervention for cleft lip surgery. The focus is usually on keeping the surgical site clean and preventing complications like infection.
C. Suction secretions away from the suture line:
This is the recommended choice. Suctioning helps maintain a clear airway and prevents secretions from affecting the surgical site. It's a crucial step in the immediate postoperative period.
D. Feed increased amounts of formula to prevent weight loss:
While feeding is an essential aspect of care, especially for nutritional support, the immediate concern in the first few days after cleft lip surgery is often related to maintaining a patent airway and preventing infection. Feeding interventions might be guided by the healthcare provider's recommendations, but it's not the primary focus in the initial postoperative period.

Correct Answer is A
Explanation
A. Proteinuria:
Minimal change nephrotic syndrome is characterized by increased permeability of the glomerular filtration barrier, leading to proteinuria. The loss of proteins, especially albumin, in the urine is a key feature.
B. Hypocalcemia:
Hypocalcemia is not typically associated with MCNS. In fact, the loss of proteins, including albumin, in the urine can lead to decreased oncotic pressure in the blood vessels, resulting in edema. However, calcium levels are usually within the normal range.
C. Hyperalbuminemia:
This is not a characteristic finding in minimal change nephrotic syndrome. In fact, the condition is associated with hypoalbuminemia due to the loss of albumin in the urine.
D. Positive for Ketones:
Ketones are not typically associated with minimal change nephrotic syndrome. Ketones in the urine are more commonly associated with conditions like diabetic ketoacidosis or starvation.
