Which of the following is not a cellular Combustion -
function? All living cells must absorb and metabolize sources of
energy, excrete waste and by-products of those processes,
and reproduce to continue offspring. Pyrotechnic processes
(i.e. combustion) are generally metaphorical.
What are mitochondria responsible for? Energy production -
Mitochondria are the energy production organelles of the
cell responsible for the major metabolic processes of
creating units of energy (e.g., ATP).
,Which if the following can cause edema? Increased lymphatic pressure -
Decreased vascular and lymphatic pressure does not
generally result in the movement and accumulation of fluid
into extravascular spaces. Increased plasma pressure in the
vascular results in hypertension, while increased lymphatic
pressure will readily result in the pooling of lymphatic
drainage into third spaces (i.e. edema).
Which of the following best describes the Two diploid cells, called daughter cells, are produced -
result of cellular reproduction? The resultant offspring of cellular reproduction is the
creation of two daughter cells after the completion of
mitosis or meiosis. Interphase is the longest period that a cell
spends its life cycle and is the preparatory stage before
cellular reproduction. Anaphase is the separation of genetic
materials to the opposing centromeres of the cell, followed
by telophase.
What indicates hypokalemia? Serum K decreases to less than 3.5 -
Normal serum potassium (K), also known as eukalemia, is
generally 3.5-5.5 mEq/L, with some variations of +/- 0.1-0.3
mEq/L depending on the laboratory testing, age, and other
potential patient-specific conditions and variations.
Alterations in fluid volume or the administration of a
supplement alone do not necessarily contribute to the
development of hypokalemia.
,What is an example of both hyperplasia Uterine enlargement due to pregnancy -
and hypertrophy? Hyperplasia is the increase in the number of cells of an
organ or tissue, while hypertrophy is the enlargement of the
cells of a given organ or tissue without a change in the
number of cells. Muscle cells grow and enlarge
(hypertrophy) in response to increased work or stress from
exercise or increased cardiovascular pressures. When a liver
is damaged or part of it is removed, it is the one internal
solid organ capable of regeneration to repair itself creating
more cells (hyperplasia). During pregnancy, the uterus must
both grow to create more cells and enlarge those existing
cells in preparation for the support of a fetus.
What regulates the sodium balance? Aldosterone -
Aldosterone is a regulatory hormone produced by the
adrenal glands to affect the kidneys' regulation of sodium,
potassium, and water excretion.
What is the alteration if the extracellular Hypotonic -
fluid volume is less than normal? In hypotonic states, the cell size is increased as a result of
water moving from the extracellular fluid (ECF) into the cell
to increase intracellular fluid. Iso- or normotonic states are a
balanced state between intra- and extracellular fluid
volumes. Hypertonic states cause water to shift out of the
cell to increase the ECF above normal.
, When in excess, what do buffers absorb? Hydrogen -
Excesses of acid or base, H+ or hydroxyl ion (OH−), are
absorbed for the purpose of maintaining pH homeostasis
(pH of 7.38-7.42)
Which of the following would a patient with pH below 7.35; Bicarbonate level below 22 mEq/L -
metabolic acidosis have? The diagnosis of metabolic acidosis requires that the testing
of arterial blood finds that the pH is less than 7.35 and the
bicarbonate level is less than 22 mEq/L.
What is the process by which RNA directs Translation -
the synthesis of polypeptides? Translation refers to this process. Transcription is another
process in which RNA is synthesized. Mutation means
genetic material has been modified through inheritance.
Creation is a term that does not apply in this context.
What is the recurrence rate for autosomal 50% -
dominant disease? For a couple in which one or both partners are affected by
the disease, the chance of each child being heterozygous
affected is 50%.
Which of the following statements is true It affects both men and women equally -
about autosomal recessive disease? A criterion for recognizing the inheritance of an autosomal
recessive disease is that men and women will be affected by
it in equal measure.
