NSG 530 Advanced Pathophysiology Exam 1 Test
UPDATED ACTUAL Exam Questions and CORRECT Answers
Question 1.
Interphase
Correct Answer: cell feeds, metabolizes and grows while replicating DNA in
preparation for mitosis
Question 2.
Prophase
Correct Answer: first appearance of chromosomes (will be 92)
Question 3.
Metaphase
Correct Answer: Centrioles pull chromosomes to opposite sides of cell
(chromatid) - 46 each side
Question 4.
Anaphase
Correct Answer: Centromeres split and sister chromatids are pulled apart
Question 5.
Telophase
Correct Answer: New nuclear membrane formed around each group of 46
chromosomes *When it goes right, euploid cells are produced*
Question 6.
Nondisjunction
Correct Answer: Error in meiosis in which homologous chromosomes fail to
separate.
Question 7.
Polyploidy
Correct Answer: condition in which an organism has extra sets of
chromosomes
, Question 8.
Triploidy
Correct Answer: when an organism has three copies of every chromsome
instead of two
Question 9.
Tetrapoloidy
Correct Answer: euploid has 92 chromosomes and fetus usually does not
survive
Question 10.
Huntington's disease
Correct Answer: Single gene disorder (trinucleotide repeat mutation)
Autosomal dominant (50% chance of passing it on) Progressive neurologic
disease with late onset (40s) Prevention- genetic testing for pregnancy
planning
Question 11.
Cystic fibrosis
Correct Answer: Single gene disorder (CFTR gene mutation) Autosomal
recessive Most common in white children Defective transport of chloride ions
cause salt imbalance- thickened secretions, digestive issues, malnutrition.
Males and females Must inherit two copies of gene (1 from each parent)
Question 12.
Turner syndrome
Correct Answer: XO chromosomal disorder, monosomy of X-affects females
Short stature, webbed neck, undeveloped breasts but female genitalia,
usually sterile
Question 13.
Down syndrome
Correct Answer: Chromosomal disorder, trisomy 21 Affects both sexes
Intellectual disability, poor muscle tone, low nasal bridge, low set ears,
protruding tongue, epicanthal fold
Question 14.
Fragile X syndrome
