A patient with type 1 diabetes mellitus is preparing for a moderate 30-minute exercise period. Which action best indicates understanding of condition management?
The patient eats a high-carbohydrate snack before the exercise period.
The patient reduces insulin use during days when exercise periods are planned.
The patient should know blood sugar before activity.
The patient administers insulin after exercise rather than before exercise.
The Correct Answer is C
A. The patient eats a high-carbohydrate snack before the exercise period: It is important for a patient with type 1 diabetes to ensure they have adequate glucose levels for exercise. Eating a high-carbohydrate snack before exercise is not always necessary unless blood glucose is low.
B. The patient reduces insulin use during days when exercise periods are planned: Insulin needs may be adjusted in relation to exercise, but reducing insulin across the board is not recommended without professional guidance.
C. The patient should know blood sugar before activity: It is important for patients with type 1 diabetes to check their blood sugar before exercise to ensure it is in a safe range. If the blood sugar is too low, they should consume a carbohydrate to prevent hypoglycemia.
D. The patient administers insulin after exercise rather than before exercise: Insulin should be timed appropriately to cover food intake and prevent post-meal hyperglycemia. Delaying insulin until after exercise could lead to high blood sugar levels.

Correct Answer is C
Explanation
A. Increase TSH levels: Radioactive iodinetherapy works by destroying overactive thyroid tissue, which will eventually lead to a decrease in T3 and T4 levels. As a result, TSH levelsmay rise in response to reduced thyroid function. However, increasing TSH levels is not the direct therapeutic effectof the iodine itself.
B. Prevent thyroid cancer: Radioactive iodinetherapy is used to treat hyperthyroidism, not to prevent thyroid cancer. It is not a preventive treatment for cancer, but rather a way to manage an overactive thyroid.
C. Destroy overactive thyroid tissue: Radioactive iodine (I-131)is used to destroy overactive thyroid tissuein Graves' disease, which helps to reduce the production of thyroid hormones. Over time, the thyroid tissue absorbs the iodine, leading to reduced thyroid function.
D. Stimulate thyroid hormone production: Radioactive iodineworks to destroy thyroid tissueand decreasethyroid hormone production, not to stimulateit. The goal is to reduce the excessive production of T3 and T4.
Correct Answer is A
Explanation
A. Hypothyroidism: Low levels of T4 and T3, combined with symptoms like weight gain, tiredness, and bradycardia, are consistent with hypothyroidism. Hypothyroidism results from an underactive thyroid gland, which produces insufficient thyroid hormones, leading to metabolic slowing and the symptoms described.
B. Hyperthyroidism: Hyperthyroidism is associated with high levels of thyroid hormones (T4 and T3), which leads to symptoms like weight loss, tachycardia (fast heart rate), nervousness, and heat intolerance, none of which are present in this client.
C. Hypokalemia: Hypokalemia (low potassium levels) typically presents with symptoms such as muscle weakness, fatigue, and cramping, but it does not explain the low thyroid hormone levels or the other signs observed in this case.
D. Tetany: Tetany is caused by hypocalcemia (low calcium levels) and is characterized by muscle spasms and tingling sensations. It is not associated with low thyroid hormone levels.
