    “You must be at 20 feet to see what normal vision sees at 60 feet.”

    d.

    “You must be at 60 feet to see what normal vision sees at 20 feet.”
    ANS:     C

    Normal vision is 20/20, which means the patient can read at 20 feet what the normal eye can read at 20 feet. Visual impairment occurs at 20/70 and legal blindness at 20/200 or more with correction. For 20/60, the patient has less acute vision and must be at 20 feet to see what normal vision sees at 60 feet.
  18. The nurse administers eyedrops to a patient and instructs the patient to apply pressure to the inner corner of the eye for 1 minute after application of the drops. Which of these, if stated by a patient, indicates to the nurse correct understanding of the main purpose of why this pressure is applied?

    a.

    “To protect the facial skin from the eyedrops.”

    b.

    “To reduce absorption of eyedrops through tear duct.”

    c.

    “To increase the onset of action of the eyedrops.”

    d.

    “To maintain greater concentration of the eyedrops.”
    ANS:     B

    Whenever eye medications, especially eyedrops, are administered, the punctum (tear duct) of the eye should have pressure applied to it for at least 1 minute. This reduces systemic absorption of the medication via the punctum.

    “Cerumen must be softened with Debrox before removal, and then an ear irrigation should be done.”

    c.

    “Wax is removed only when there is evidence of infection.”

    d.

    “Cerumen is removed regularly and thoroughly.”
    ANS:    A

    The ear is generally self-cleaning. Wax is normally removed during showering. Wax serves as a protective mechanism to lubricate and trap foreign material.

    a.

    It whistles constantly.

    b.

    The patient ignores verbal stimuli.

    c.

    It is properly placed in the ear.

    d.

    The patient converses easily.
    ANS:    D

    a.

    Speaking in a low-pitched voice

    b.

    Speaking in a high-pitched voice

    c.

    Speaking in a very loud voice

    d.

    Speaking in a soft voice
    ANS:    A

    Presbycusis is an age-related change in which progressive hearing loss is caused by loss of hair cells and decreased blood supply in the ear, resulting in a decreased ability to hear high-frequency sounds. Talking in a lower pitch helps with communication.
  25. What structure changes the shape of the lens of the eye?

    a.

    Ciliary muscle

    b.

    Iris

    c.

    Retina

    d.

    Optic nerve
    ANS:    A

    The ciliary body has a circular muscle that surrounds the edge of the lens and is connected to the lens by suspensory ligaments. The shape of the lens is changed by the ciliary muscle, which permits the focusing of light from objects at varying distances.

    a.

    Hair cells for hearing

    b.

    Ganglion cells for vibrations

    c.

    Hair cells for balance

    d.

    Ganglion cells for balance
    ANS:    A

    The medial canal is the cochlear duct, which contains the receptors for hearing in the organ of Corti. The receptors are called hair cells, which contain endings of the cochlear branch of the eighth cranial nerve.
  27. Which of the following is the cranial nerve for hearing?

    a.

    CN II

    b.

    CN IV

    c.

    CN VI

    d.

    CN VIII
    ANS:    D

    When the hair cells in the ear bend, they generate impulses that are carried by the eighth cranial nerve to the brain for interpretation.
  28. 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?

    a.

    Weber’s test

    b.

    Whisper test

    c.

    Rinne’s test

    d.

    Romberg’s test
    ANS:    D

    Romberg’s test, or falling test, is a simple test to assess vestibular function. If the patient has difficulty maintaining balance or loses balance, it can indicate an inner ear problem. If a fall appears likely, be prepared to support the patient to prevent injury.
  29. 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?

    a.

    “My eyes will need to be dilated before the procedure.”

    b.

    “The scanner will take a picture in about 2 seconds.”

    c.

    “A digital image of most of my retina will be produced for the doctor to view.”

    d.

    “This test is used to help detect eye disease early.”
    ANS:    A

    Digital imaging is a newer way of viewing the retina without requiring the use of dilating eyedrops. The instrument takes a digital picture of the retina in 2 seconds. The majority of the retina is viewable and assists in early detection of eye disease.
  30. Which of the following are common age-related changes in vision and hearing? (Select all that apply.)

    a.

    Increased pupil size and response to light

    b.

    Decreased lacrimal secretions

    c.

    Loss of ability to hear low-frequency sounds

    d.

    Distorted depth perception

    e.

    Yellowing of the lens

    f.

    Presbycusis
    ANS: B, D, E, F

    To be true, A should be decreased pupil size and responsiveness to light, and C should be loss of ability to hear high-frequency sounds.
  31. 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.)

    a.

    “I can watch television without moving my eye too much.”

    b.

    “I can listen to music or an audiotaped book but should not read or watch TV.”

    c.

    “I should try to open my eyelid under the patch hourly while awake.”

    d.

    “I should exercise my patched eye four times daily.”

    e.

    “I should apply pressure to the tear duct of the eye every 5 minutes.”

    f.

    “When I change the patch, it should be taped securely enough to help the eyelid stay closed.”
    ANS: A, C, D, E

    A, C, D, and E should not be done, so the patient would need further instruction for understanding. B and F are correct and would indicate understanding.
  32. 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.)

    a.

    Electroretinography
