Mrs. Tomberg brings her 4-day-old infant to your office with a concern of a yellowish skin tone.
Which of the following statements best describes the rationale for the skin tone?
A. Increased formation of subcutaneous tissue causes a yellow hue.
B. Capillaries broken during the birth process turn the skin slightly yellow as bruises heal.
C. The yellowish color results from increased fat metabolism and heat production.
D. The infant has hyperbilirubinemia. - ANSWER-D:CorrectHyperbilirubinemia, or physiologic
jaundice, is present to a mild degree in many newborn infants. It usually starts after the first day
of life and disappears by the eighth to tenth day but may persist for as long as 3 to 4 weeks.
Intense and persistent jaundice suggests liver disease, a hemolytic process, or severe,
overwhelming infection.
Mr. Russel is a 17-year-old adolescent patient who presents with a complaint of acne. He asks
the examiner why teens have more problems with acne than children. Which of the following
would be an appropriate response?
A. "Children have better hygiene habits than adolescents because of parental guidance."
B. "Adolescents have reduced blood flow to the epidermal layer of the skin, making them more
prone to infections."
C. "At puberty, adolescents begin to secrete more oil from sebaceous glands."
,D. "Children have very little skin mass, which prevents development of acne." - ANSWER-C:
CorrectDuring adolescence, the apocrine glands enlarge and become active, causing increased
axillary sweating and sometimes body odor. Sebaceous glands increase sebum production in
response to increased hormone levels, primarily androgen, giving the skin an oily appearance
and predisposing the individual to acne.
While examining the skin of an 87-year-old woman, the nurse observes significant tenting.

C. The skin becomes dry with significant flaking.
D. There is a loss of adipose tissue and elasticity. - ANSWER-D:CorrectTenting occurs in the older
adult as a result of loss of adipose tissue and elasticity. The skin often appears to hang loosely
on the bony frame as a result of a general loss of elasticity, loss of underlying adipose tissue,
and years of gravitational pull.
Mr. Allen is a 66-year-old man who presents to your clinic for follow-up for his chronic

A. the width of the nail base.

with a variety of respiratory and cardiovascular diseases, cirrhosis, colitis, and thyroid disease.
