MULTIPLE CHOICE

1. A faculty member explains the Human Genome Project to a class of nursing students. Which information about this project is correct?
A.
It began in the 1980s to find the basic building blocks of human proteins.
B.
The findings will be used to create better matches for animal-to-human transplants.
C.
The goal is to identify exact DNA sequences and genes occurring in humans.
D.
Information from the project is being used to find preventative measures for diseases.

ANS: C
The Human Genome Project began in 1990 with an overarching goal to identify the exact DNA sequences and genes that occur in humans. It is hoped that the findings will lead to new methods of diagnosing, treating, and perhaps preventing human disease and disorders.

2. A nurse is interested in studying the functions and interactions of the genes in the human genome. What branch of science should this nurse pursue?
A.
Biology
B.
Genetics
C.
Genomics
D.
Inheritance

ANS: C
Genomics is the study of the functions and interactions of all the genes in the genome. Genetics is the study of single genes and their effects. Both are subsets of biology, which is the study of life and living matter. Inheritance is the way in which genetic material is passed on to subsequent generations.

3. A nursing instructor is explaining genetic concepts to a class of students. Where in the cell does the instructor tell the students that each person’s genes can be found?
A.
Golgi body
B.
Lysosome
C.
Mitochondria
D.
Nucleus

ANS: D
Most genes are located on chromosomes found in the nucleus of cells. Golgi bodies process cellular proteins. Lysosomes break down waste and cellular debris. Mitochondria are responsible for cellular energy production.

4. A couple wishes to determine the chances of having a blue-eyed baby. Both parents have brown eyes, but have heterozygous gene pairs for eye color. Calculate the odds of their having a child with blue eyes.
A.
10%
B.
20%
C.
25%
D.
50%

ANS: C
Each parent has a heterozygous gene pair for brown eyes, which means that each parent has one blue gene and one brown gene. Using a Punnett square, one can calculate the odds of their having a blue-eyed baby to be 25%.

5. A nurse reads in a patient’s chart that the patient has a condition caused by monosomy X. What can the nurse conclude about this patient?
A.
Female with one missing X chromosome
B.
Female with very feminine features
C.
Male with one extra X chromosome
D.
Male with very feminine features

ANS: A
A monosomy condition is one in which only one of the paired chromosomes is present. In this case, the patient would have one or more cells with one X chromosome and nothing else. Turner’s syndrome is the most common example of this defect; children born with this syndrome are female and exhibit juvenile external genitalia, underdeveloped ovaries, short stature, webbing of the neck, and possible intellectual deficits and cardiac disorders.
