The client asks the nurse which type of diabetes is caused by no insulin secretion by the pancreas. What is the best response by the nurse?

A. Presence of renal or hepatic disease: Metformin, commonly prescribed for type 2 diabetes, is primarily excreted by the kidneys. Patients with renal impairment are at increased risk of metformin accumulation, potentially leading to lactic acidosis. Assessing for the presence of renal or hepatic disease helps determine the appropriate dosage of metformin and reduces the risk of adverse effects.
B. Fluid retention: Metformin does not typically cause fluid retention; however, monitoring for signs of fluid retention is important, especially in patients with underlying conditions such as heart failure, as fluid retention can exacerbate their condition.
C. Need for diagnostic tests involving the use of contrast dyes: Metformin can increase the risk of lactic acidosis, particularly in patients undergoing procedures involving contrast dyes. Temporarily discontinuing metformin before such procedures reduces the risk of adverse effects.
D. Weight gain: Metformin is associated with weight neutrality or even modest weight loss. Monitoring weight changes can help assess treatment response and overall health.
E. Presence of heart failure: Metformin is contraindicated in patients with severe heart failure due to the potential risk of lactic acidosis. Assessing for the presence of heart failure helps ensure safe prescribing practices and avoids potential complications associated with metformin use in this population.

A. It may interfere with cartilage development: Tetracyclines can deposit in developing bones and teeth, potentially causing discoloration and affecting bone growth in children.
B. Children become dehydrated easily: While dehydration is a concern in any illness, it's not the specific reason to avoid tetracyclines in children.
C. Photosensitivity may occur: Photosensitivity can be a side effect of some medications, but it's not the main reason to avoid tetracyclines in children.
D. Children's teeth may become discoloured: Tetracycline can stain developing teeth, causing permanent discoloration. This is the major reason to avoid them in young children.
