questions
,Which of the following is not a cellular function? - VERRIFIED ANSWERS✔️✔️--
Combustion -
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? - VERRIFIED ANSWERS✔️✔️--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? - VERRIFIED ANSWERS✔️✔️--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 result of cellular reproduction? - VERRIFIED
ANSWERS✔️✔️--Two diploid cells, called daughter cells, are produced -
,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? - VERRIFIED ANSWERS✔️✔️--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 and hypertrophy? - VERRIFIED
ANSWERS✔️✔️--Uterine enlargement due to pregnancy -
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? - VERRIFIED ANSWERS✔️✔️--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 fluid volume is less than normal? - VERRIFIED
ANSWERS✔️✔️--Hypotonic -
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? - VERRIFIED ANSWERS✔️✔️--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 metabolic acidosis have? - VERRIFIED
ANSWERS✔️✔️--pH below 7.35; Bicarbonate level below 22 mEq/L -
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.
