Final answer:
Tim's medical assistant should be cautious about the risk of a hypoglycemic reaction, which is a direct adverse effect of insulin therapy in Type 1 Diabetes Mellitus. Monitoring blood sugar levels and adjusting insulin dosage is essential to prevent this condition.
Step-by-step explanation:
Hypoglycemia in Type 1 Diabetes Mellitus
Tim, having been recently diagnosed with Type 1 Diabetes Mellitus and now starting insulin therapy, must be educated about the potential adverse effects, particularly a hypoglycemic reaction. Hypoglycemia occurs when the blood glucose level falls too low, often due to an excessive dose of insulin or inadequate food intake. Symptoms of hypoglycemia include sweating, tremors, fainting attacks, muscle weakness, and could lead to unconsciousness or death if severe and left untreated. Therefore, it is crucial that Tim, as well as his medical assistant, monitor his blood sugar levels closely and adjust his insulin dosage accordingly to prevent hypoglycemia.
In Type 1 Diabetes Mellitus (T1DM), the immune system attacks the beta cells in the pancreas that produce insulin. This means that people with T1DM need to manage their condition with insulin injections or infusions. Failure to properly manage insulin dosage can result in hypoglycemia or, less commonly in the context of insulin therapy, severe hyperglycemia when insulin is insufficient.
To sum up, among the listed options, Tim's medical assistant should be most cautious about the risk of a hypoglycemic reaction (A), which is a direct adverse effect of insulin therapy. The other conditions listed—malignant hyperthermia, malignant hypertension, and severe hyperglycemia—are generally not direct adverse effects of insulin therapy in T1DM.
