Essay Questions
103) Many medications can be administered transdermally by applying patches that contain the medication to the surface of the skin. These patches can be attached anywhere on the skin except the palms of the hands and the soles of the feet. Why?
Answer: Thick skin slows the rate of diffusion of the medication and thus decreases its effectiveness. In addition, excessive sweat formed on the palms of the hands and soles of the feet would make the patch fall off more readily.
Learning Outcome: 5-1
Blooms Taxonomy: Application
104) Explain why the rate of dehydration is greater when a person is immersed in seawater than when in fresh water.
Answer: Salty ocean water is very hypertonic compared to bodily fluids, while fresh lake water is very hypotonic. Hence, in the sea, due to osmosis water will leave the body, accelerating the rate of dehydration. In fresh water, water will be gained.
Learning Outcome: 5-1
Blooms Taxonomy: Comprehension
105) In a condition known as sunstroke, the victim appears flushed, the skin is warm and dry, and the body temperature rises dramatically. Explain these observations based on what you know concerning the role of the skin in thermoregulation.
Answer: When the body temperature increases, more blood flow is directed to the vessels of the skin. The red cells in the blood give the skin a redder-than-usual color and account for the victims flushed appearance. The skin is dry because the sweat glands are not producing sweat (avoiding further dehydration). Without evaporation cooling, not enough heat is dissipated from the skin, the skin is warm, and the body temperature rises. This situation represents positive feedback operating in a disease state.

106) A new mother notices that her 6-month-old infant has a yellow-orange complexion. Fearful that the child may have jaundice, she takes him to her pediatrician. After examining the child and learning about the infants diet, the pediatrician declares him perfectly healthy and advises the mother to watch the childs diet. What is likely the cause for the change in skin color?
Answer: The infant probably has a fondness for vegetables that are high in carotene, such as sweet potatoes, squash, and carrots. It is not uncommon for parents to feed babies what they will eat best. If the child consumes large amounts of carotene, the yellow-orange pigment will be stored in the skin, producing a yellow-orange skin color.
Learning Outcome: 5-2
Blooms Taxonomy: Application
107) Why is regional infection or inflammation of the skin usually very painful?
Answer: Inflammation of the skin is painful because sensory receptors are abundant in the skin. Changes associated with swelling stimulate the sensory receptors, resulting in a painful sensation.
Learning Outcome: 5-5
Blooms Taxonomy: Comprehension
108) Why is a subcutaneous injection with a hypodermic needle a useful method of administering drugs?
Answer: The subcutaneous layer has a limited capillary supply and contains no vital organs; thus, the potential for tissue damage is reduced.
Learning Outcome: 5-6
Blooms Taxonomy: Comprehension
109) Explain why warm, dry climates feel cooler than warm, humid climates, even though the air temperatures are the same.
Answer: In arid environments, sensible perspiration evaporates from the skin more rapidly than in humid climates, where the air is already saturated with water. This carries heat away from the skin rapidly, leading to a cool sensation. In humid regions, the sweat does not evaporate as readily, and thus the bodys cooling mechanism is hampered.
Learning Outcome: 5-8
Blooms Taxonomy: Application
110) Why is scab formation important in wound healing?
Answer: Scabs temporarily restore epidermal integrity, restricting further entry of microorganisms. They also prevent the loss of fluids, maintaining internal fluid balance, and protect the delicate granulation tissue during tissue recovery.
Learning Outcome: 5-10
Blooms Taxonomy: Comprehension
111) Vanessas 80-year-old grandmother sets her thermostat at 26C (80F) and wears a sweater on balmy spring days. When asked why, the grandmother says she feels cold. What is a possible cause for her feeling cold?
Answer: Most elderly people have poor blood flow to the skin. Thus, their skin becomes cold. This triggers thermal receptors in the skin to signal cold skin. The brain interprets this as a cold body temperature.
