A nurse in a clinic is reviewing the laboratory values of a client who has primary hypothyroidism. The nurse should anticipate an elevation of which of the following laboratory values?

Free T4

Thyroid stimulating hormone (TSH)

Serum T3

Serum T4

Answer and Explanation

The Correct Answer is B

Choice A reason:
In primary hypothyroidism, the thyroid gland is underactive and does not produce sufficient thyroid hormones, including Free T4. Therefore, we would not expect an elevation of Free T4 in primary hypothyroidism; instead, its levels would typically be low or normal.

Choice B reason:
Thyroid stimulating hormone (TSH) levels are elevated in primary hypothyroidism because the pituitary gland releases more TSH in an attempt to stimulate the thyroid gland to produce more thyroid hormones. This is a compensatory response to the low levels of circulating thyroid hormones, particularly thyroxine (T4).

Choice C reason:
Serum T3 levels may be low or normal in primary hypothyroidism. T3 is the active form of thyroid hormone and is usually converted from T4. If T4 levels are low, T3 levels may also be affected; however, T3 levels are not the primary diagnostic marker for hypothyroidism and do not typically show elevation in this condition.

Choice D reason:
Serum T4 levels are typically low in primary hypothyroidism because the thyroid gland is not producing enough of this hormone. An elevation of serum T4 would not be expected unless the patient is receiving treatment for hypothyroidism.

Correct Answer is C

Explanation

Choice A reason:
A tingling sensation is not the primary concern when planning preoperative teaching for an amputation due to a severe gangrenous infection. While some patients may experience tingling due to nerve damage or as part of phantom limb sensation, the focus of preoperative teaching should be on managing pain and understanding the recovery process.

Choice B reason:
Telling a patient that their pain will gradually become less severe may be misleading. Post-amputation, patients often experience significant pain, including phantom limb pain, which can be intense and challenging to manage. Preoperative teaching should set realistic expectations about postoperative pain and its management.

Choice C reason:
Phantom pain is a real phenomenon experienced by many amputees, where they feel pain in the amputated limb as if it were still there. It is not merely psychological but has physiological underpinnings related to the nerves and brain's interpretation of signals. Preoperative teaching should include information about phantom limb pain, its potential occurrence, and strategies for managing it.

Choice D reason:
It is unrealistic to suggest that the pain will disappear soon after the amputation. Recovery from an amputation can be a lengthy process, and pain management is a critical component. Patients need to be prepared for the possibility of ongoing pain and the need for pain management strategies postoperatively.

A. Avoid prolonged sitting. B. Sleep on a soft mattress. C. Apply heat for 10 minutes every hour. D. Sleep in a side-lying position with flexed knees. E. Try padded shoe insoles.

Correct Answer is ["A","D","E"]

Explanation

Choice B reason:
Sleeping on a soft mattress is not recommended for preventing low back pain. A medium-firm mattress often provides better support for the spine. A soft mattress may allow the body to sink in too deeply, causing misalignment of the spine during sleep.

Choice C reason:
Applying heat for 10 minutes every hour is not a standard recommendation for preventing low back pain. While heat therapy can help relax muscles and relieve pain, it is typically advised to apply heat for longer periods, such as 15-20 minutes, and not as frequently as every hour.

Choice D reason:
Sleeping in a side-lying position with flexed knees can help maintain the natural curve of the spine and minimize back strain. This position can also reduce pressure on the back and is often recommended for those with low back pain.

Choice E reason:
Trying padded shoe insoles can help minimize back strain by providing additional support and cushioning for the feet, which can improve alignment and reduce the impact on the back during walking or standing.
