WGU D027 Course Material Questions & Answers(Latest )

Which of the following is not a cellular function? -ANSWER 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? -ANSWER 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? -ANSWER 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? -ANSWER 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? -ANSWER 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 n
