A nurse is reinforcing home safety instructions with the guardian of an 18-month- old toddler.
Which of the following responses by the guardian indicates an understanding of the teaching?

This is because the client has hypothyroidism, which means their thyroid gland does not produce enough thyroid hormone. Levothyroxine is a synthetic form of thyroid hormone that can replace the missing hormone and normalize the TSH level. The client’s TSH level is 8.9 mIU/L, which is above the normal range of 0.4 to 4.0 mIU/L. This indicates that the client’s current dosage of levothyroxine is insufficient and needs to be increased.

Choice A is wrong because thyroid ablation therapy is a treatment for hyperthyroidism, not hypothyroidism.

Thyroid ablation therapy involves destroying part or all of the thyroid gland with radioactive iodine or surgery, which reduces the production of thyroid hormone.

This would worsen the client’s condition and symptoms.

Choice C is wrong because lovastatin is a statin drug that lowers cholesterol levels. Hypothyroidism can cause high cholesterol levels, but this is usually corrected by levothyroxine therapy. Replacing lovastatin with cholestyramine, a bile acid sequestrant that also lowers cholesterol levels, would not address the underlying cause of hypothyroidism and would not improve the client’s TSH level.

Choice D is wrong because restricting the intake of iodized salt would not help the client with hypothyroidism. Iodine is an essential element for the synthesis of thyroid hormone, but most people in developed countries get enough iodine from their diet.

Hypothyroidism is usually caused by autoimmune disease, not iodine deficiency.

Moist heat can help reduce pain and stiffness in the joints by increasing blood flow and relaxing the muscles. Moist heat can be applied using warm compresses, heating pads, or warm baths.

Choice A is wrong because using a recliner when sitting for long periods can increase pressure on the knees and decrease circulation. A better option is to use a straight-backed chair with a footstool.

Choice C is wrong because sleeping on a soft mattress can cause poor alignment of the spine and joints, which can worsen pain and mobility. A firm mattress is recommended for clients with osteoarthritis.

Choice D is wrong because placing large pillows under the knees when lying in bed can limit the range of motion of the knees and cause contractures. A small pillow under the knees can provide some support and comfort, but it should not be too large or too high.
