Question 1

The nurse is teaching a patient with a hearing disorder. Which of the following hearing losses would the nurse include are helped with a hearing aid?

Accepted Answer

Conductive hearing loss is caused by a problem in the outer or middle ear, which can be helped with a hearing aid.

Question 2

The nurse evaluates that a patient's hearing aid is functioning properly when which of these occurs?

Accepted Answer

A functioning hearing aid should allow the patient to converse easily. A whistling sound indicates feedback, and ignoring verbal stimuli may indicate a problem with the hearing aid or the patient's hearing. Proper placement is important but does not necessarily indicate functionality.

Question 3

The nurse places eye drops for a patient with an injured eye and covers the eye with a patch as prescribed. Discharge instructions are given to the patient. Which of the following patient statements indicate that further instruction is needed? (Select all that apply.?

Accepted Answer

Watching television (A) can cause eye movement, which should be minimized. Opening the eyelid under the patch (C) and exercising the patched eye (D) are not recommended as they can interfere with healing. Applying pressure to the tear duct (E) is not a standard instruction for an eye patch.

Question 4

The nurse is caring for a patient who has presbycusis. What intervention would most enhance the nurse's communication with the patient?

Accepted Answer

Presbycusis is age-related hearing loss that typically affects the ability to hear higher frequencies. Speaking in a low-pitched voice can make it easier for someone with presbycusis to understand speech, as they may have difficulty hearing higher-pitched sounds.

Question 5

Which of the following is the cranial nerve for hearing?

Accepted Answer

CN VIII, also known as the vestibulocochlear nerve, is responsible for both hearing (cochlear branch) and balance and spatial orientation (vestibular branch).

Question 6

What are the receptors in the organ of Corti?

Accepted Answer

The receptors in the organ of Corti are the hair cells, which are responsible for hearing. Ganglion cells are not receptors, but instead transmit signals from sensory cells to the brain. While hair cells in the vestibular system are responsible for balance, the organ of Corti specifically relates to hearing.

Question 7

The nurse is caring for a patient who is blind. What technique should the nurse use when ambulating the patient?

Accepted Answer

Preceding the patient with the patient's hand on the nurse's elbow is the best technique when ambulating a blind patient. This allows the patient to feel the nurse's movements and make necessary adjustments while maintaining control of their own body. Walking in front of the patient or behind the patient could cause the patient to trip or become disoriented.

Question 8

When being tested for visual acuity, the patient should hold a handheld visual acuity chart approximately ________________inches from the eyes.

Accepted Answer

The answer of When being tested for visual acuity, the...

Question 9

The nurse has reinforced teaching with a patient about diagnostic tests that evaluate eye muscle balance. Which of the following tests identified by the patient would indicate a correct understanding of the teaching? (Select all that apply.?

Accepted Answer

The corneal light reflex and cover test are both used to evaluate eye muscle balance. The corneal light reflex test assesses the alignment of the eyes by observing the reflection of light on the corneas, while the cover test evaluates the ability of the eyes to maintain focus and alignment when one eye is covered.

Question 10

The nurse is preparing a patient who will be having a digital retinal scan. Which of the following statements by the patient indicates further teaching is necessary?

Accepted Answer

The patient's statement that "My eyes will need to be dilated before the procedure" indicates further teaching is necessary because digital retinal scans do not always require dilation of the eyes. This technology often allows for a detailed view of the retina without the need for dilation, depending on the equipment used and the specific condition being assessed.

Question 11

Which of the following are common age-related changes in vision and hearing? (Select all that apply.?

Accepted Answer

B) As people age, their lacrimal glands often produce fewer tears, leading to drier eyes. D) Aging can affect depth perception due to changes in the eye's lens and reduced field of vision. E) The lens of the eye can become more yellow with age, affecting color perception. F) Presbycusis is the loss of hearing that gradually occurs in most individuals as they grow older, affecting the ability to hear higher frequency sounds, not low-frequency sounds as mentioned in C.

Question 12

The nurse is assisting with a patient's physical examination. For which of the following tests would the nurse anticipate the need to plan for patient safety?

Accepted Answer

Romberg's test evaluates the patient's balance and requires the patient to stand with their feet together, arms at their sides, and eyes closed. It is important for the nurse to plan for patient safety during this test to prevent falls or injury. Weber's test, Whisper test, and Rinne's test do not require specific safety measures.

Question 13

What structure changes the shape of the lens of the eye?

Accepted Answer

The ciliary muscle is responsible for changing the shape of the lens of the eye. When it contracts, it changes the shape of the lens to allow for clear viewing of objects at different distances.
