A flat macular hemorrhage is called a(n):
- purpura
- ecchyomosis
- petechiae
- hemangioma
- purpura
Purpura is a flat, macular, red to purple hemorrhage that is a confluent and extensive patch of petechiae and ecchymoses greater than 3 mm.
An ecchymosis is petechiae that are greater than 3 mm.
Petechiae are tiny punctuate hemorrhages that are 1 to 3 mm, round and discrete, and dark red, purple, or brown caused by bleeding from superficial capillaries.
Hemangiomas are vascular lesions caused by a benign proliferation of blood vessels in the dermis.
A student nurse has been assigned to teach fourth graders about hygiene. While preparing, the student nurse adds information about the sweat glands. Which of the following should be included while discussing this topic?
- There are two types of sweat glands: the eccrine and the sebaceous.
- The evaporation of sweat, a dilute saline solution, increases body temperature.
- Eccrine glands produce sweat and are mainly located in the axillae, anogenital area, and navel.
- Newborn infants do not sweat and use compensatory mechanisms to control body temperature.
- Newborn infants do not sweat and use compensatory mechanisms to control body temperature.
Newborn infants’ eccrine glands do not secrete sweat in response to heat until the first few months of life; newborn temperature regulation is ineffective.
There are two types of sweat glands: the eccrine glands and the apocrine glands.
The evaporation of sweat reduces body temperature.
The apocrine glands produce a thick, milky secretion and open into the hair follicles; they are located mainly in the axillae, anogenital area, nipples, and navel.
Functions of the skin include:
- production of vitamin C.
- temperature regulation.
- the production of new cells by melanocytes.
- the secretion of a drying substance called sebum.
temperature regulation
Functions of the skin include protection, prevention of penetration, perception (of touch, pain, temperature, and pressure), temperature regulation, identification, communication, wound repair, absorption and excretion, and production of vitamin D.
The skin produces vitamin D, not vitamin C.
The basal cell layer of the epidermis forms new skin cells. Melanocytes produce melanin, which gives brown tones to the skin and hair.
Sebum is produced by the sebaceous glands to lubricate the skin and hair.
Risk factors that may lead to skin disease and breakdown include:
- loss of protective cushioning of the dermal skin layer.
- decreased vascular fragility.
- a lifetime of environmental trauma.
- increased thickness of the skin.
a lifetime of environmental trauma.
An accumulation of factors placing the aging person at risk for skin disease and breakdown include the thinning of the skin, the decrease in vascularity and nutrients, the loss of protective cushioning of the subcutaneous layer, a lifetime of environmental trauma to skin, the social changes of aging, the increasingly sedentary lifestyle, and the chance of immobility.
Aging results in the loss of protective cushioning of the subcutaneous layer of the skin.
Aging results in decreased vascularity of the skin.
Aging results in thinning of the skin.
What term refers to a linear skin lesion that runs along a nerve route?
- Zosteriform
- Annular
- Dermatome
- Shingles
Zosteriform
Zosteriform describes a lesion that has a linear arrangement along a nerve root.
Annular describes a lesion that is circular and begins in the center and spreads to the periphery.
A dermatome is an area of skin that is mainly supplied by a single spinal nerve.
Shingles (herpes zoster) are small grouped vesicles that emerge along the route of a cutaneous sensory nerve, then pustules, then crusts; shingles is caused by the herpes zoster virus.
The components of a nail examination include:
- contour, consistency, and color.
- shape, surface, and circulation.
- clubbing, pitting, and grooving.
- texture, toughness, and translucency.
contour, consistency, and color.
The nails should be assessed for shape and contour, consistency, and color.
To determine if a dark skinned patient is pale, the nurse should assess the color of the:
- conjunctivae
- ear lobes.
- palms of the hands.
- skin in the antecubital space.
conjunctivae
To detect pallor in a dark skinned individual, the nurse should assess an area with the least pigmentation, such as the conjunctivae or mucous membranes.
An example of a primary lesion is a(n):
- erosion
- ulcer
- urticaria
- port-wine stain.
urticaria
Urticaria is a primary lesion; a primary lesion is a lesion that develops on previously unaltered skin.
Erosions are secondary lesions; a secondary lesion is a lesion that changes over time or changes because of a factor such as scratching or infection.
Ulcers are secondary lesions; a secondary lesion is a lesion that changes over time or changes because of a factor such as scratching or infection.
A port-wine stain is a vascular lesion.
A scooped out, shallow depression in the skin is called a/an:
- ulcer

An erosion is a scooped out, shallow depression in the skin.
Bleeding into the periosteum during birth is known as:
- caput succedaneum.
- craniosynostosis
- molding
- cephalhematoma
cephalhematoma
A cephalhematoma is a subperiosteal hemorrhage resulting from birth trauma.
A caput succedaneum is edematous swelling and ecchymosis of the presenting part of the head caused by birth trauma.
Craniosynostosis is marked asymmetry caused by a severe deformity caused by premature closure of the sutures resulted in a long, narrow head.
Molding of the cranial bones during passage through the birth canal makes the head asymmetric and ridges more prominent.
Craniosynostosis is a severe deformity caused by:
- premature closure of the sutures.
- increased intracranial pressure.
- a localized bone disease that softens, thickens, and deforms bone.
- excess growth hormone or a deficit in thyroid hormone.
premature closure of the sutures
Craniosynostosis is marked asymmetry caused by a severe deformity caused by premature closure of the sutures resulting in a long, narrow head.
Hydrocephalus (obstruction of drainage of cerebrospinal fluid) results in excessive accumulation of cerebrospinal fluid, increasing intracranial pressure, and enlargement of the head.
Paget disease (osteitis deformans) is a localized bone disease of unknown etiology that softens, thickens, and deforms bone.
Acromegaly results from excessive secretion of growth hormone from the pituitary after puberty. Congenital hypothyroidism and myxedema are caused by thyroid hormone deficiency.

Facial characteristics of congenital hypothyroidism include low hairline, hirsute forehead, swollen eyelids, narrow palpebral fissures, widely spaced eyes, depressed nasal bridge, puffy face, thick tongue protruding through an open mouth, and a dull expression.
Kyphosis of the spine is common with aging. To compensate, older adults will:
- increase their center of gravity.
- extend their heads and jaws forward.
- stiffen their gait.
- shuffle
The older adult may show an increased anterior cervical (concave or inward) curve when the head and jaw are extended forward to compensate for kyphosis of the spine.

The location in the brain where optic nerve fibers from the temporal fields of vision cross over is identified as the:
- optic chiasm.
- fovea centralis.
- optic disc.
- choroid.
optic chiasm.
At the optic chiasm, nasal fibers (from both temporal visual fields) cross over.
The fovea centralis is the area of the retina that has the sharpest and keenest vision.
The optic disc is the area in which fibers from the retina converge to form the optic nerve.
The choroid is the middle vascular layer of the eye; the choroid has dark pigmentation to prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina.
