A nurse is caring for a client with a urine specific gravity of less than 1.005, polyuria, and nocturia. The nurse recognizes that which of the following physiologic findings is the likely cause?

Increased insulin production

Increased adrenocorticotropic hormone (ACTH)

Low levels of T3, T4

Insufficient antidiuretic hormone (ADH)

Answer and Explanation

The Correct Answer is D

A. Increased insulin production would not cause polyuria and low specific gravity urine; rather, hyperglycemia from lack of insulin can cause high specific gravity due to glucose in urine.

B. Increased ACTH affects cortisol production but is not directly related to urine concentration or polyuria.

C. Low T3 and T4 levels are associated with hypothyroidism, which typically does not cause polyuria or decreased specific gravity.

D. Insufficient ADH, as seen in diabetes insipidus, leads to the inability to concentrate urine, resulting in a low specific gravity, polyuria, and nocturia due to excessive water loss.

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.

A. "The medication causes the pupil to constrict and will lower the pressure in the eye." B. "The medication will help dilate the eye to prevent pressure from occurring." C. "The medication will relax the muscles of the eyes and prevent blurred vision." D. "The medication will help block the responses that are sent to the muscles in the eye."

Correct Answer is A

Explanation

A. Miotic medications work by constricting the pupil, which opens the trabecular meshwork and facilitates the drainage of aqueous humor, thus lowering intraocular pressure in clients with glaucoma.

B. Miotics do not dilate the pupil; they constrict it. Dilation would actually increase intraocular pressure, which is not therapeutic in glaucoma.

C. While these medications do affect eye muscles, they do not specifically prevent blurred vision; their primary effect is on eye pressure.

D. Miotics do not block nerve responses; they work by direct action on the eye muscles to promote fluid drainage and reduce pressure.
