A client is scheduled for an adrenocorticotropic hormone (ACTH) stimulation test to help diagnose suspected Addison's disease. What should the nurse include when teaching the client about this test?

This test measures the kidneys' response to ACTH.

If you have Addison's disease, plasma cortisol levels will rise in response to ACTH.

You will take a dose of ACTH by mouth the evening before the test.

ACTH is a hormone that is normally produced by the pituitary gland.

Answer and Explanation

The Correct Answer is D

A.   The ACTH stimulation test measures the adrenal glands' response to ACTH, not the kidneys.
B.   In Addison’s disease, the adrenal glands are damaged and unable to produce sufficient cortisol even when stimulated by ACTH. Therefore, plasma cortisol levels will not rise significantly in response to
ACTH administration in individuals with Addison’s disease.
C.   The ACTH stimulation test involves administering ACTH via injection, not orally.
D.   ACTH (adrenocorticotropic hormone) is produced by the pituitary gland and stimulates the adrenal glands to produce cortisol. The ACTH stimulation test assesses how well the adrenal glands respond to ACTH, which is crucial for diagnosing conditions like Addison’s disease, where the adrenal glands do not respond appropriately.

Correct Answer is D

Explanation

A. Increased sensitivity to cold is not typically associated with Bell's Palsy or ptosis but might be a general sensation change related to nerve involvement.
B. Drooling from the corner of the mouth is a result of facial weakness affecting the muscles responsible for controlling saliva and mouth closure. While drooling is a common symptom of Bell's Palsy due to impaired muscle control, it is not a description of ptosis. Ptosis specifically refers to the drooping of the upper eyelid.
C. Ringing in the ear, or tinnitus, is not a direct symptom of ptosis. Tinnitus might be associated with various conditions affecting the ear or cranial nerves but is not specifically indicative of ptosis, which is related to eyelid drooping.
D. Ptosis refers to the drooping or sagging of the upper eyelid. In the context of Bell's Palsy, this drooping occurs on the affected side due to weakness or paralysis of the muscles that normally help elevate the eyelid.

A. A client who is being treated for otitis media B. A client who has experienced an injury to the eardrum C. A client who works in a loud environment D. A client whose ear canal is impacted with wax

Correct Answer is C

Explanation

A. Otitis media is an infection or inflammation of the middle ear. This condition primarily affects the middle ear structures and can cause conductive hearing loss, which is due to problems with sound transmission through the outer or middle ear.
B. An injury to the eardrum, such as a perforation, can lead to conductive hearing loss. This occurs because the eardrum (tympanic membrane) is crucial for transmitting sound waves from the outer ear to the middle ear. While an eardrum injury affects sound transmission, it does not directly damage the inner ear or auditory nerve, so it does not typically cause sensorineural hearing loss.
C. Exposure to loud noise is a common cause of sensorineural hearing loss. Prolonged or intense noise exposure can damage the sensory hair cells in the cochlea or the auditory nerve pathways, leading to permanent hearing loss. This type of hearing loss is due to damage in the inner ear or auditory nerve rather than the outer or middle ear structures.
D. Impacted earwax can cause conductive hearing loss by blocking sound transmission through the ear canal. This type of hearing loss is due to a blockage and is usually reversible once the wax is removed. It does not cause sensorineural hearing loss, which involves damage to the inner ear or auditory nerve.
