NURS 6501-Advanced Pathophysiology Quiz 1
certified Exam Questions With Correct Answers
What is osmotic pressure?-correct-answer-The amount of hydrostatic pressure
| | | | | | |
required to oppose the osmotic movement of water
| | | | | | | |
What is the resting membrane potential?-correct-answer-Difference in electrical
| | | | | | |
charge across the membrane at rest
| | | | | |
What is action potential?-correct-answer-the change in electrical potential
| | | | | | |
associated with the passage of an impulse along the membrane of a muscle cell or
| | | | | | | | | | | | | | |
nerve cell.
| |
How does DNA replicate?-correct-answer-DNA molecule unwinds and each strand
| | | | | | | |
is a template for complementary base pairing; each daughter helix contains an
| | | | | | | | | | | |
intact strand from the parent helix and a newly synthesized strand therefore DNA
| | | | | | | | | | | | |
replication is semiconservative
| | |
What are the four phases of the cell cycle?-correct-answer-(1) the S phase, during
| | | | | | | | | | | |
which DNA synthesis takes place in the cell nucleus; (2) the G2 phase, the period
| | | | | | | | | | | | | | |
,2 || |P |a |g
|e
between the completion of DNA synthesis and the next phase (M); (3) the M
| | | | | | | | | | | | |
phase, which involves both nuclear (mitotic) and cytoplasmic (cytokinetic)
| | | | | | | | |
division; and (4) the G1 phase (growth phase), after which the cycle begins again.
| | | | | | | | | | | | |
What are the four stages of the M phase (Mitosis)?-correct-answer-prophase,
| | | | | | | | |
metaphase, anaphase, and telophase.
| | | |
What is DNA composed of?-correct-answer-deoxyribose, a phosphate molecule,
| | | | | | |
and four types of nitrogenous bases. The physical structure of DNA is a double
| | | | | | | | | | | | | |
helix
|
What does DNA polymerase do?-correct-answer-Joins individual nucleotides to
| | | | | | |
make complementary strands and proofreads the sequence of bases and corrects
| | | | | | | | | | |
errors
|
What is transcription?-correct-answer-The process of making RNA from DNA
| | | | | | | |
What is translation?-correct-answer-the decoding of an mRNA message into a
| | | | | | | | |
protein

What are diploid somatic cells?-correct-answer-Body Cells
| | | | |
What are haploid gametes?-correct-answer-sperm and egg cells
| | | | | |
What is a karyotype?-correct-answer-A display of every pair of homologous
| | | | | | | | |
chromosomes within a cell, organized according to size and shape
| | | | | | | | | |
How common are chromosome abnormalities?-correct-answer-1 in 150 live
| | | | | | |
births, leading cause of mental retardation and miscarriage
| | | | | | | |
What is polyploidy?-correct-answer-condition in which an organism has extra sets
| | | | | | | | |
of chromosomes
| |
What is aneuploidy?-correct-answer-Abnormal number of chromosomes.
| | | | |
What is trisomy?-correct-answer-3 copies of a chromosome
