Which of the following clients is at risk for sensorineural hearing loss?

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

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is ["50"]

Explanation

Flow rate in gtt/min = (Volume in mL * Drop factor) / Time in minutes.
The prescribed volume is 150 mL/hr. Since there are 60 minutes in an hour, the time for one hour would be 60 minutes. The drop factor is 20 gtt/mL.
(150 mL/hr * 20 gtt/mL) / 60 min/hr = 3000 gtt/hr / 60 min/hr = 50 gtt/min.
Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min.

Correct Answer is B

Explanation

A. This action is crucial if there is a suspicion of elder abuse, as adult protective services (APS) can investigate the situation thoroughly and take necessary measures to protect the client. However, before making such a notification, it is important to assess the immediate safety of the client and gather preliminary information.
B. This is a prudent initial action to ensure that the client is in a safe environment away from the caregiver, who may be the suspected abuser. It allows the nurse to conduct a private and thorough assessment of the client without the potential influence or intimidation from the caregiver. This step is critical for ensuring the client's safety and obtaining unbiased information.
C. While reporting to the caregiver’s employment agency may be a step in the process, it is not the immediate priority. The primary focus should be on ensuring the client’s safety and assessing the situation before contacting external agencies.
D. While it is important to gather information about how the injury occurred, the immediate priority is to ensure the client's safety and provide an opportunity for a private assessment. The presence of the caregiver during this conversation could influence the client's responses or cause additional stress.
