NURS 6030 Exam 1 Mod 1-3 Cell Biology, Fluids, and
Genetics Questions With Complete Solutions
A force that moves fluid in and out of capillaries termed active
transport works how? Correct Answers the movement of ions
or molecules across a cell membrane into a region of higher
concentration, assisted by enzymes and requires energy.
A force that moves fluid in and out of capillaries termed
diffusion works how? Correct Answers Sodium movement
down concentration gradient from high to low concentration.
A force that moves fluid in and out of capillaries termed osmosis
works how? Correct Answers Water movement to an area of
higher sodium/ particle concentration.
A high negative predictive value would mean what in terms of
specificity and sensitivity? Correct Answers The specificity
would be high. Because the percent of people with true negative
results would be high.
A high positive predictive value would mean what in terms of
specificity and sensitivity? Correct Answers the test would
have high sensitivity because the proportion of people who have
the disease and get a positive test would be high.
A low negative predictive value would mean what in terms of
specificity and sensitivity? Correct Answers The specificity
would be low. Because the percent of people with a true
negative result would be low.
,A low positive predictive value would mean what in terms of
specificity and sensitivity? Correct Answers the test would
have low sensitivity because the proportion of people who test
positive and actually get a positive test would be low.
Acquired Infections Correct Answers Develop after birth: ex:
Herpes Zoster Oticus (Chicken Pox)
Mumps
Syphilis. Note: hospital acquired infections are also termed
nosocomial infections. These terms can be used interchangeably.
Allele Correct Answers Different forms of a gene
An adverse reaction of hyperkalemia? Correct Answers
Cardiac arrythmias: why? Increased extracellular potassium
levels result in depolarization of the membrane potentials of
cells due to the increase in the equilibrium potential of
potassium.
Anoxia is? Correct Answers absence of oxygen
Are males or females more likely to be carriers of X-linked
traits? Correct Answers Females are more likely to be carriers
but are less likely to express them the traits.
Autosomal dominant gene disorder is: Correct Answers single
gene disorder with a 50% chance to pass regardless of sex. Ex:
neurofibromatosis and Marfans
Cell communication : Autocrine Correct Answers hormone
gets released from the cell and it goes back to its own cell
, Cell communication : Paracrine Correct Answers Hormone
gets release from one cell and travels to another target cell
Cell communication: Endocrine Correct Answers hormone is
released from an endocrine gland into the blood stream and
circulates to the target cell
Cellular adaptation: Atrophy Correct Answers Decrease in cell
size, due to decrease in workload or disuse, lack of hormonal
stimulation, inadequate nutrition, ischemia,
Cellular adaptation: dysplasia Correct Answers Abnormal
changes in size, shape, and organization of cells. Not considered
a true adaptive change because they can revert back to normal or
progress to become a malignancy. EX HPV; cervical cancer.
Cellular adaptation: Hypertrophy Correct Answers increase in
cell size, due to increased workload, increased hormone
stimulation EX: enlarged heart is caused by hypertrophy of cells
and hypertension
Cellular adaptation: metaplasia Correct Answers replacement
of one differentiated cell type with another. EX cells changing
into different cells in GERD
Congenital disease Correct Answers A disease present at birth.
Dad has autosomal dominant disease and heterozygous for the
dominant gene. Mom does not have abnormalities. Will their
child be at risk? Correct Answers Yes, a 50%
