c. select the largest speculum that will fit in the canal.
d. ask the patient to keep his or her eyes closed.
e. pull the auricle down and forward.

A

C Select the largest speculum that will comfortably fit in the patient’s ear. The handle should be held between the thumb and the index finger, supported on the middle finger. The patient’s head should be positioned toward the opposite shoulder. To straighten the external auditory in an adult, pull the auricle up and back. There is no reason for the patient to keep her or his eyes shut.

24
Q

Normal tympanic membrane color is

a. amber.
b. chalky white.

a. avoid performing otoscopic examinations.
b. clean the inner ear with soap.
c. instill alcohol into the ear.
d. never use a cerumen spoon.
e. avoid instilling fluids.

A

E Any ear irrigation should be avoided in the presence of otitis externa, perforated tympanic membrane, myringotomy tube, or mastoid cavity. These are not contraindications for otoscopic examinations or clearing the outer canal of cerumen; only the auricle can be cleaned with soap.

27
Q

When hearing is evaluated, which cranial nerve is being tested?

a. III
b. IV
c. VIII
d. IX
e. XII

A

A

E Placing the fork on the midline vertex of the patient’s head is the Weber test, a test for conductive hearing loss that lateralizes to the affected ear.

30
Q

To perform the Rinne test, place the tuning fork on the

a. top of the head.
b. mastoid bone.
c. forehead.
d. preauricular area.
e. occiput.

A

B The fork is initially placed against the mastoid bone for the Rinne test, a test for sensorineural loss.

31
Q
You are performing Weber and Rinne hearing tests. For the Weber test, the sound lateralized to the unaffected ear; for the Rinne test, the air conduction to bone conduction-to-ratio was less than 2:1. You interpret these findings as suggestive of a. 
a defect in the inner ear. 
b. a defect in the middle ear. 
c. otitis externa. 
d. impacted cerumen. 
e. serous otitis.
A

A These results are consistent with a sensorineural hearing loss, a defect in the inner ear. Otitis externa, impacted cerumen, and serous otitis are conditions that can cause conductive hearing problems.

Q
A smooth red tongue with a slick appearance may indicate a. 
a niacin or vitamin B12 deficiency. 
b. oral cancer. 
c. recent use of antibiotics. 
d. a fungal infection. 
e. a geographic tongue.
A

A A smooth red tongue with a slick appearance may indicate a niacin or vitamin B12 deficiency. Oral cancer involves lesions; recent use of antibiotics can turn the tongue yellow-brown to black and hairy; and fungal infections result in slightly raised white, cream-colored, or yellow spots in the mouth. A geographic tongue has irregular areas of whitish and red areas.

37
Q

A hairy tongue with yellowish brown to black elongated papillae on the dorsum

a. is indicative of oral cancer.
b. is sometimes seen after antibiotic therapy.
c. usually indicates a vitamin deficiency.
d. usually indicates anemia.
e. is characteristic of a geographic tongue.

b. insert the tongue blade obliquely against the tongue.
c. lift the tongue upward with gloved fingers.
d. pull the gauze-wrapped tongue to each side.
e. ask the patient to lift the tongue upward.

A

D To inspect the lateral borders of the tongue, you should wrap the tongue with a piece of gauze and then pull the tongue to each side for inspection. The other maneuvers do not result in adequate lateral border inspection.

39
Q

A 6-month-old who can hear well can be expected to

a. exhibit the Moro reflex.
b. stop breathing in response to sudden noise.
c. turn his or her head toward the source of sound.
d. imitate simple words.
e. understand simple phrases.

A

C Six-month-old infants turn their heads toward the source of sound, and they start babbling, but they begin imitating speech sounds closer to 10 months of age. Understanding simple phrases such as “no-no” and “bye-bye” occurs between 10 and 12 months. The Moro reflex and cessation of breathing in response to noise are lost by 3 months of age.

40
Q

Which variation may be an expected finding in the ear examination of a newborn?

a. Diffuse light reflex
b. Purulent material in the ear canal
c. Redness and swelling of the mastoid process
d. Small perforations of the tympanic membrane
e. Increased mobility and clarity of the tympanic membrane

A

A The newborn’s tympanic membrane does not become conical for several months; therefore, the light reflex appears diffuse.

41
Q

For best results, an otoscopic and oral examination in a child should be

a. conducted at the beginning of the assessment.
b. done after inspection.
c. performed at the end of the examination.
d. performed before palpation.
e. deferred until they can fully cooperate.

A

C Because young children often resist otoscopic and oral examination, it may be wise to postpone these procedures until the end of the examination after you have gained some trust.

a. A patient with a temperature of 100.4° F and a toothache
b. A drooling patient with muffled voice and stridor
c. A patient with purulent drainage from the ear and a cough
d. A patient with a seal-like barking cough and anorexia
e. A patient whose epiglottis is visible when the tongue is depressed

A

B Suspected retropharyngeal abscess, which can cause drooling, a muffled voice, and stridor, is a pediatric emergency because it occludes the airway.

43
Q

Which abnormality is common during pregnancy?

a. Eruption of additional molars
b. Hypertrophy of the gums
c. Epstein pearls
d. Otitis media
e. Koplik spots

A

B The gums of pregnant women may appear reddened, swollen, and spongy, with the hypertrophy resolving within 2 months of delivery.

44
Q

Expected physical changes associated with older adults include

a. shiny buccal mucosa.
b. teeth appear shorter.
c. wetter nasal mucosa.
d. bristly hairs in the vestibule.
e. smoothing of the tongue.

A

D With age, the buccal mucosa becomes less shiny, the teeth appear longer because of receding gums, the nasal mucosa are drier, the tongue may appear more fissured, and more bristly hairs appear in the nose, especially in men.

45
Q

Intense pain with movement of the pinna is most closely associated with

a. sinusitis.
b. otitis externa.
c. purulent otitis media.
d. bacterial otitis media.
e. otitis media with effusion.

A

B Suspect otitis externa (swimmer’s ear) when pulling the pinna reproduces ear pain. The other conditions do not commonly cause the same finding.

47
Q

Which of the following illicit drugs is commonly associated with nasal septum perforation?

a. Heroin
b. Marijuana
c. PCP
d. Ecstasy
e. Cocaine

A

E Long-term cocaine snorting causes ischemic necrosis of the septal cartilage and leads to perforation of the nasal septum.

48
Q

Evidence-based practice suggests that the strongest predictor of sinusitis is a.
a maxillary toothache.
b. dull or opaque sinus transilluminations.
c. ineffective decongestants and colored nasal drainage.
d. purulent nasal secretions.
e. any combination of the above.

A

E Evidence-based practice suggests that the strongest predictor of sinusitis is any combination of these symptoms including maxillary toothache, purulent nasal secretions, dull or opaque sinus transillumination, poor response to decongestants, and colored nasal discharge.

49
Q

You are interviewing a parent whose child has a fever, is batting at her right ear, and is irritable. You ask the parent about the child’s appetite and find that the child has a decreased appetite. This additional finding is most suggestive of

a. acute otitis media.
b. otitis externa.
c. serous otitis media.
d. middle ear effusion.
