Chapter 12: Skin, Hair, and Nails Flashcards
- The nurse educator is preparing an education module for the nursing staff on the epidermal layer of skin. Which of these statements would be included in the module? The epidermis is:
a. Highly vascular.
b. Thick and tough.
c. Thin and nonstratified.
d. Replaced every 4 weeks.
ANS: D
The epidermis is thin yet tough, replaced every 4 weeks, avascular, and stratified into several zones.
- The nurse educator is preparing an education module for the nursing staff on the dermis layer of skin. Which of these statements would be included in the module? The dermis:
a. Contains mostly fat cells.
b. Consists mostly of keratin.
c. Is replaced every 4 weeks.
d. Contains sensory receptors.
ANS: D
The dermis consists mostly of collagen, has resilient elastic tissue that allows the skin to stretch, and contains nerves, sensory receptors, blood vessels, and lymphatic vessels. It is not replaced every 4 weeks.
- The nurse is examining a patient who tells the nurse, “I sure sweat a lot, especially on my face and feet but it doesn’t have an odor.” The nurse knows that this condition could be related to:
a. Eccrine glands.
b. Apocrine glands.
c. Disorder of the stratum corneum.
d. Disorder of the stratum germinativum.
ANS: A
The eccrine glands are coiled tubules that directly open onto the skin surface and produce a dilute saline solution called sweat. Apocrine glands are primarily located in the axillae, anogenital area, nipples, and naval area and mix with bacterial flora to produce the characteristic musky body odor. The patient’s statement is not related to disorders of the stratum corneum or the stratum germinativum.
- A newborn infant is in the clinic for a well-baby checkup. The nurse observes the infant for the possibility of fluid loss because of which of these factors?
a. Subcutaneous fat deposits are high in the newborn.
b. Sebaceous glands are overproductive in the newborn.
c. The newborn’s skin is more permeable than that of the adult.
d. The amount of vernix caseosa dramatically rises in the newborn.
ANS: C
The newborn’s skin is thin, smooth, and elastic and is relatively more permeable than that of the adult; consequently, the infant is at greater risk for fluid loss. The subcutaneous layer in the infant is inefficient, not thick, and the sebaceous glands are present but decrease in size and production. Vernix caseosa is not produced after birth.
- The nurse is bathing an 80-year-old man and notices that his skin is wrinkled, thin, lax, and dry. This finding would be related to which factor in the older adult?
a. Increased vascularity of the skin
b. Increased numbers of sweat and sebaceous glands
c. An increase in elastin and a decrease in subcutaneous fat
d. An increased loss of elastin and a decrease in subcutaneous fat
ANS: D
An accumulation of factors place the aging person at risk for skin disease and breakdown: the thinning of the skin, a 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, a increasingly sedentary lifestyle, and the chance of immobility.
- During the aging process, the hair can look gray or white and begin to feel thin and fine. The nurse knows that this occurs because of a decrease in the number of functioning:
a. Metrocytes.
b. Fungacytes.
c. Phagocytes.
d. Melanocytes.
ANS: D
In the aging hair matrix, the number of functioning melanocytes decreases; as a result, the hair looks gray or white and feels thin and fine. The other options are not correct.
- During an examination, the nurse finds that a patient has excessive dryness of the skin. The best term to describe this condition is:
a. Xerosis.
b. Pruritus.
c. Alopecia.
d. Seborrhea.
ANS: A
Xerosis is the term used to describe skin that is excessively dry. Pruritus refers to itching, alopecia refers to hair loss, and seborrhea refers to oily skin.
- A 22-year-old woman comes to the clinic because of severe sunburn and states, “I was out in the sun for just a couple of minutes.” The nurse begins a medication review with her, paying special attention to which medication class?
a. Nonsteroidal antiinflammatory drugs for pain
b. Tetracyclines for acne
c. Proton pump inhibitors for heartburn
d. Thyroid replacement hormone for hypothyroidism
ANS: B
Drugs that may increase sunlight sensitivity and give a burn response include sulfonamides, thiazide diuretics, oral hypoglycemic agents, and tetracycline.
- A woman is leaving on a trip to Hawaii and has come in for a checkup. During the examination the nurse learns that she has diabetes and takes oral hypoglycemic agents. The patient needs to be concerned about which possible effect of her medications?
a. Increased possibility of bruising
b. Skin sensitivity as a result of exposure to salt water
c. Lack of availability of glucose-monitoring supplies
d. Importance of sunscreen and avoiding direct sunlight
ANS: D
Drugs that may increase sunlight sensitivity and give a burn response include sulfonamides, thiazide diuretics, oral hypoglycemic agents, and tetracycline.
- A 13-year-old girl is interested in obtaining information about the cause of her acne. The nurse should share with her that acne:
a. Is contagious.
b. Has no known cause.
c. Is caused by increased sebum production.
d. Has been found to be related to poor hygiene.
ANS: C
Approximately 90% of males and 80% of females will develop acne; causes are increased sebum production and epithelial cells that do not desquamate normally.
- A 75-year-old woman who has a history of diabetes and peripheral vascular disease has been trying to remove a corn on the bottom of her foot with a pair of scissors. The nurse will encourage her to stop trying to remove the corn with scissors because:
The woman could be at increased risk for infection and lesions because of her chronic
a. disease.
With her diabetes, she has increased circulation to her foot, and it could cause severe
b. bleeding.
She is 75 years old and is unable to see; consequently, she places herself at greater risk for
c. self-injury with the scissors.
With her peripheral vascular disease, her range of motion is limited and she may not be able
d. to reach the corn safely.
ANS: A
A personal history of diabetes and peripheral vascular disease increases a person’s risk for skin lesions in the feet or ankles. The patient needs to seek a professional for assistance with corn removal.
- The nurse keeps in mind that a thorough skin assessment is extremely important because the skin holds information about a person’s:
a. Support systems.
b. Circulatory status.
c. Socioeconomic status.
d. Psychological wellness.
ANS: B
The skin holds information about the body’s circulation, nutritional status, and signs of systemic diseases, as well as topical data on the integumentary system itself.
- A patient comes in for a physical examination and complains of “freezing to death” while waiting for her examination. The nurse notes that her skin is pale and cool and attributes this finding to:
a. Venous pooling.
b. Peripheral vasodilation.
c. Peripheral vasoconstriction.
d. Decreased arterial perfusion.
ANS: C
A chilly or air-conditioned environment causes vasoconstriction, which results in false pallor and coolness (see Table 12-1).
- A patient comes to the clinic and tells the nurse that he has been confined to his recliner chair for approximately 3 days with his feet down and he asks the nurse to evaluate his feet. During the assessment, the nurse might expect to find:
a. Pallor
b. Coolness
c. Distended veins
d. Prolonged capillary filling time
ANS: C
Keeping the feet in a dependent position causes venous pooling, resulting in redness, warmth, and distended veins. Prolonged elevation would cause pallor and coolness. Immobilization or prolonged inactivity would cause prolonged capillary filling time (see Table 12-1)
- A patient is especially worried about an area of skin on her feet that has turned white. The health care provider has told her that her condition is vitiligo. The nurse explains to her that vitiligo is:
a. Caused by an excess of melanin pigment
b. Caused by an excess of apocrine glands in her feet
c. Caused by the complete absence of melanin pigment
d. Related to impetigo and can be treated with an ointment
ANS: C
Vitiligo is the complete absence of melanin pigment in patchy areas of white or light skin on the face, neck, hands, feet, body folds, and around orifices—otherwise, the depigmented skin is normal.
- A patient tells the nurse that he has noticed that one of his moles has started to burn and bleed. When assessing his skin, the nurse pays special attention to the danger signs for pigmented lesions and is concerned with which additional finding?
a. Color variation
b. Border regularity
c. Symmetry of lesions
d. Diameter of less than 6 mm
ANS: A
Abnormal characteristics of pigmented lesions are summarized in the mnemonic ABCD: asymmetry of pigmented lesion, border irregularity, color variation, and diameter greater than 6 mm.
- A patient comes to the clinic and states that he has noticed that his skin is redder than normal. The nurse understands that this condition is due to hyperemia and knows that it can be caused by:
a. Decreased amounts of bilirubin in the blood
b. Excess blood in the underlying blood vessels
c. Decreased perfusion to the surrounding tissues
d. Excess blood in the dilated superficial capillaries
ANS: D
Erythema is an intense redness of the skin caused by excess blood (hyperemia) in the dilated superficial capillaries.
- During a skin assessment, the nurse notices that a Mexican-American patient has skin that is yellowish-brown; however, the skin on the hard and soft palate is pink and the patient’s scleras are not yellow. From this finding, the nurse could probably rule out:
a. Pallor
b. Jaundice
c. Cyanosis
d. Iron deficiency
ANS: B
Jaundice is exhibited by a yellow color, which indicates rising levels of bilirubin in the blood. Jaundice is first noticed in the junction of the hard and soft palate in the mouth and in the scleras.
- A black patient is in the intensive care unit because of impending shock after an accident. The nurse expects to find what characteristics in this patient’s skin?
a. Ruddy blue.
b. Generalized pallor.
c. Ashen, gray, or dull.
d. Patchy areas of pallor.
ANS: C
Pallor attributable to shock, with decreased perfusion and vasoconstriction, in black-skinned people will cause the skin to appear ashen, gray, or dull (see Table 12-2).
