The primary purpose of
... [Show More] the ciliated mucous membrane in the nose is to:
a. Warm the inhaled air.
b. Filter out dust and bacteria.
c. Filter coarse particles from inhaled air.
d. Facilitate the movement of air through the nares. - ANS: B. Filter out dust and
bacteria
The nasal hairs filter the coarsest matter from inhaled air, whereas the mucous blanket
filters out dust and bacteria. The rich blood supply of the nasal mucosa warms the
inhaled air.
The projections in the nasal cavity that increase the surface area are called the:
a. Meatus.
b. Septum.
c. Turbinates.
d. Kiesselbach plexus. - ANS: C. Turbinates
The lateral walls of each nasal cavity contain three parallel bony projections: the
superior, middle, and inferior turbinates. These increase the surface area, making more
blood vessels and mucous membrane available to warm, humidify, and filter the inhaled
air.
The nurse is reviewing the development of the newborn infant. Regarding the sinuses,
which statement is true in relation to a newborn infant?
a. Sphenoid sinuses are full size at birth.
b. Maxillary sinuses reach full size after puberty.
c. Frontal sinuses are fairly well developed at birth.
d. Maxillary and ethmoid sinuses are the only sinuses present at birth. - ANS: D.
Maxillary and ethmoid sinuses are the only sinuses present at birth.
Only the maxillary and ethmoid sinuses are present at birth. The sphenoid sinuses are
minute at birth and develop after puberty. The frontal sinuses are absent at birth, are
fairly well developed at age 7 to 8 years, and reach full size after puberty.
The tissue that connects the tongue to the floor of the mouth is the:
a. Uvula.
b. Palate.
c. Papillae.
d. Frenulum. - ANS: D. Frenulum
The frenulum is a midline fold of tissue that connects the tongue to the floor of the
mouth. The uvula is the free projection hanging down from the middle of the soft palate.
The palate is the arching roof of the mouth. Papillae are the rough, bumpy elevations on
the tongue's dorsal surface.
The salivary gland that is the largest and located in the cheek in front of the ear is the
_________ gland.
a. Parotid
b. Stensen's
c. Sublingual
d. Submandibular - ANS: A. Parotid
The mouth contains three pairs of salivary glands. The largest, the parotid gland, lies
within the cheeks in front of the ear extending from the zygomatic arch down to the
angle of the jaw. The Stensen's duct (not gland) drains the parotid gland onto the buccal
mucosa opposite the second molar. The sublingual gland is located within the floor of
the mouth under the tongue. The submandibular gland lies beneath the mandible at the
angle of the jaw.
In assessing the tonsils of a 30 year old, the nurse notices that they are involuted,
granular in appearance, and appear to have deep crypts. What is correct response to
these findings?
a. Refer the patient to a throat specialist.
b. No response is needed; this appearance is normal for the tonsils.
c. Continue with the assessment, looking for any other abnormal findings.
d. Obtain a throat culture on the patient for possible streptococcal (strep) infection. -
ANS: B. No response is needed; this appearance is normal for the tonsils.
The tonsils are the same color as the surrounding mucous membrane, although they
look more granular and their surface shows deep crypts. Tonsillar tissue enlarges
during childhood until puberty and then involutes.
The nurse is obtaining a health history on a 3-month-old infant. During the interview, the
mother states, "I think she is getting her first tooth because she has started drooling a
lot." The nurse's best response would be:
a. "You're right, drooling is usually a sign of the first tooth."
b. "It would be unusual for a 3 month old to be getting her first tooth."
c. "This could be the sign of a problem with the salivary glands."
d. "She is just starting to salivate and hasn't learned to swallow the saliva." - ANS: D.
"She is just starting to salivate and hasn't learned to swallow the saliva."
In the infant, salivation starts at 3 months. The baby will drool for a few months before
learning to swallow the saliva. This drooling does not herald the eruption of the first
tooth, although many parents think it does.
The nurse is assessing an 80-year-old patient. Which of these findings would be
expected for this patient?... [Show Less]
