NR 509 WEEK 5 QUIZLET CURRENTLY TESTING
WITH DETAILED QUESTIONS AND CORRECT
ANSWERS GRADED A+| CHAMBERLAIN
UNIVERSITY
1. The nurse educator is preparing an education module
on the epidermal layer of skin. Which statement should
be included in the module?
A. The epidermis is highly vascular.
B. The epidermis is thick, tough, and fibrous.
C. The epidermis is thin and nonstratified.
D. The epidermis is replaced completely every 4 weeks.
• Answer: D
• Rationale: The epidermis is an avascular outer layer that
continuously sheds and regenerates, completely replacing
itself every 4 weeks. It is stratified into several layers, unlike
the underlying dermis which contains blood vessels and
connective tissue.
2. When educating nursing staff on the dermal layer of the
skin, which characteristic should be highlighted?
,A. It consists primarily of adipose fat tissue.
B. It is composed mainly of keratinized cells.
C. It undergoes complete turnover every 4 weeks.
D. It contains nerve endings and sensory receptors.
• Answer: D
• Rationale: The dermis is the inner supportive layer of skin
containing collagen, blood vessels, nerves, sensory
receptors, and appendicular structures. Adipose tissue forms
the subcutaneous layer, while keratinized cells form the
epidermis.
3. A patient presents with excessive facial and pedis
sweating that lacks a noticeable odor. The nurse
attributes this finding to the activity of which glands?
A. Apocrine glands
B. Eccrine glands
C. Sebaceous glands
D. Ceruminous glands
• Answer: B
, • Rationale: Eccrine glands produce a clear, watery sweat
directly onto the skin surface to regulate temperature and do
not produce body odor. Apocrine glands, located primarily in
axillary and anogenital regions, produce a thicker secretion
that reacts with bacterial flora to produce body odor.
4. A neonate is admitted for a routine assessment. The
nurse monitors closely for fluid and heat loss primarily
because:
A. Subcutaneous fat deposits are excessive in newborns.
B. Sebaceous glands are inactive and underproductive.
C. Newborn skin is more permeable than adult skin.
D. Vernix caseosa concentration increases significantly after birth.
• Answer: C
• Rationale: Newborn skin is thin, smooth, and significantly
more permeable than adult skin, putting the infant at higher
risk for fluid loss and impaired thermoregulation. Vernix
caseosa is present at birth but decreases thereafter.
5. An 80-year-old patient exhibits thin, lax, dry, and
wrinkled skin. The nurse understands this structural
change in aging skin is caused by:
A. Increased vascularity within the dermal layer.
, B. Hyperplasia of sweat and sebaceous glands.
C. Increased elastin production combined with subcutaneous fat
gain.
D. Loss of skin elasticity due to elastin breakdown and
subcutaneous fat loss.
• Answer: D
• Rationale: The aging process causes epidermal thinning,
loss of dermal vascularity, degeneration of collagen and
elastin, and loss of subcutaneous fat. These combined
structural alterations lead to skin laxity, dryness, and
wrinkling.
6. An older adult client notices their hair becoming thin,
fine, and gray. The nurse explains that hair color change
in aging is primarily due to a decrease in:
A. Phagocytes
B. Melanocytes
C. Keratinocytes
D. Histiocytes
• Answer: B
