A nurse is providing education regarding the adrenal cortex production of mineralocorticoids. The nurse should include that mineralocorticoids influence which of the following?

Major effects on the metabolism of almost all organs of the body

Fluid and electrolyte balance

Regulate carbohydrate and protein metabolism

The release of the ACTH from the anterior lobe of the pituitary gland

Answer and Explanation

The Correct Answer is B

A. While hormones from the adrenal cortex do influence various metabolic processes, mineralocorticoids primarily focus on fluid and electrolyte balance rather than having major effects on all organs' metabolism.
B. Mineralocorticoids, such as aldosterone, play a crucial role in regulating fluid and electrolyte balance by promoting sodium retention and potassium excretion in the kidneys.
C. Regulation of carbohydrate and protein metabolism is mainly the function of glucocorticoids, not mineralocorticoids.
D. The release of ACTH is regulated by corticotropin-releasing hormone (CRH) from the hypothalamus, not directly influenced by mineralocorticoids.

Correct Answer is B

Explanation

A. Serum thyroxine (T4) is typically decreased in primary hypothyroidism due to reduced thyroid hormone production.
B. In primary hypothyroidism, the thyroid gland fails to produce sufficient hormones, which leads to an increase in thyroid-stimulating hormone (TSH) as the pituitary gland tries to stimulate thyroid function. Elevated TSH is a common finding in primary hypothyroidism.
C. Serum T3 is usually decreased in primary hypothyroidism since the production of T3 and T4 is reduced.
D. Free T4 is typically low in primary hypothyroidism as the thyroid gland is underactive and not producing adequate levels of thyroid hormones.

A. Ensure that the vest supporting the halo device is snug and properly aligned. B. Apply a thick layer of zinc oxide cream around the pin sites. C. Pad the areas of skin breakdown with foam dressing to reduce friction and pressure. D. Loosen the halo device to reduce pressure on the skin.

Correct Answer is C

Explanation

A. While ensuring proper alignment is important, it does not address the existing skin breakdown and irritation.
B. Applying zinc oxide cream may not be appropriate as it can trap moisture, potentially worsening the skin condition around pin sites.
C. Padding the areas of skin breakdown with foam dressing is an appropriate intervention as it can provide cushioning, reduce friction, and protect the skin from further injury.
D. Loosening the halo device could compromise the stabilization it provides and may not effectively address skin integrity issues.
