The nurse is examining a patient's ears and notices cerumen in the external canal. Which of these statements about cerumen is correct?
Cerumen is necessary for transmitting sound through the auditory canal.
The presence of cerumen is indicative of poor hygiene.
The purpose of cerumen is to protect and lubricate the ear.
Wet, honey-colored cerumen is a sign of infection.
The Correct Answer is C
A. Cerumen does not transmit sound; it is a protective substance that traps dust, debris, and microorganisms, helping to keep the ear canal clean.
B. The presence of cerumen is not necessarily indicative of poor hygiene. It is a normal bodily secretion that serves an important protective function.
C. Cerumen (earwax) serves to protect the ear canal from infection and irritation and lubricates the ear canal, helping to prevent dryness.
D. Wet, honey-colored cerumen is typically normal and not a sign of infection. If cerumen is associated with infection, it may appear yellowish, thick, or accompanied by other symptoms like pain or discharge.

Correct Answer is B
Explanation
A. Enlarged lymph nodes are associated with hypertensive heart disease is not a correct association. Hypertension does not directly cause lymph node enlargement.
B. They are most likely enlarged as a result of the throat infection is the correct answer. Enlarged lymph nodes, especially under the jaw, are commonly seen in response to infections, particularly in the throat (such as a viral or bacterial infection like pharyngitis).
C. You should probably see an oncologist to rule out lymphedema is an unnecessary response at this time. Lymphedema usually presents with other symptoms, and the patient's symptoms (fever, sore throat, and localized lymph node enlargement) suggest an infection rather than cancer.
D. You probably have a blockage in the thoracic lymph duct is not a common cause of localized lymph node enlargement. Blockages in the thoracic duct would affect lymphatic flow more generally and would present with more systemic symptoms.
Correct Answer is A
Explanation
A. Constriction of the pupils is the correct response. When testing for accommodation, the pupils constrict as the patient focuses on a near object, demonstrating normal accommodation.
B. Disconjugate movement of the eyes (where the eyes do not move together) is an abnormal finding. The eyes should move symmetrically and conjugately (together).
C. Consensual light reflex refers to the pupillary response to light in one eye causing a constriction in both eyes, but this is not part of the accommodation test.
D. Dilation of the pupils is the opposite of what should occur during accommodation. The pupils should constrict when focusing on a near object.
