1. Fever and hyperthermia describe conditions in which body temperature
is higher than the normal range. When does hyperthermia occur?: When the
body's set point is unchanged, but the temperature goes up
2. A client has developed heart failure. The doctor reviews the client's
chest x-ray and notes that the heart has enlarged. The changes in the size
and shape of the heart are the result of:: Hypertrophy Explanation:
Cells adapt to changes in their environment and in their work demands by
changing their size, number, and characteristics. An increase in work results in
cells undergoing hypertrophy and increasing in size. Hyperplasia is an increase in
the number of cells in an organ or tissue. A decrease in work demands or adverse
environmental conditions results in cells atrophy, or reducing in size. Hypoplasia is
underdevelopment or incomplete development of a tissue or an organ
3. When explaining to a group of parents of school-aged children the
importance of protein intake, the nurse emphasizes which food choices that
contain all essential amino acids in adequate amounts per serving? Select
all that apply.: Eggs
4. Which of the following conditions is characterized by a deficiency of
the liver enzyme phenylalanine hydroxylase?: Phenylketonuria
5. A client asks the health care provider if any technology exists to limit
faulty gene activity from producing unwanted disease proteins. The best
response would be:: DNA ?
6. A client asks why his temperature is always below 98.6°F. The nurse
responds:: Normal core temperature varies between individuals within the range
of 97.0°F to 99.5°F.
Explanation:
Core temperature is normally maintained within a range of 36.0°C to 37.5°C (97.0°F
to 99.5°F). A core temperature greater than 41°C (105.8°F) or less than 34°C
(93.2°F) usually indicates that the body's thermoregulatory ability is impaired. Body

heat is generated in the tissues of the body, transferred to the skin surface by the
blood, and then released into the environment surrounding the body. The
thermoregulatory center regulates the temperature of the deep body tissues, or
"core" of the body, rather than the surface temperature. Internal core temperatures
reach their highest point in late afternoon and evening and their lowest point in the
early morning hours
7. A biochemical event, such as nucleotide change, deletion, or insertion,
that produces a new allele is called which of the following?: Mutation
A mutation is a biochemical event, such as nucleotide change, deletion, or insertion,
that produces a new allele.
-Polymorphism refers to genes that have more than one normal allele at the same
locus.
-Although gene expression usually follows a dominant or recessive pattern, it is
possible for both alleles of a gene pair to be fully expressed in the heterozygote.
This is codominance.
-When a person inherits a dominant mutant gene, but fails to express it, it is called
reduced penetrance.
8. Which of the following cancers is the leading cause of cancer death?:
Lung
Lung cancer is the leading cause of cancer deaths of men and women in the United
States
9. The nurse is considering targeting a risk group for preventative
education. Which of the following groups would benefit most from this
education?: Obese patients age 20-40
The excess body fat of obesity often significantly impairs health. As a result, obesity
is the second leading cause of preventable death in the United States in adults
under age 70, and the third leading cause in all ages, following smoking and
hypertension. It has been predicted that the health effects of obesity will result in a
shorter life expectancy for today's youth.
