NURS 6030 Exam 1 Questions With Complete Solutions
1 liter= ? pounds Correct Answers 2.2 pounds
absolute refractory period Correct Answers period of time
following an action potential during which no additional action
potential can be evoked regardless of the level of stimulation
action potential Correct Answers sudden change in resting
membrane potential, triggered by electrical or chemical stimuli.
depolarization--Na+ rush in
repolarization--Na+ channels close, K+ rush out
*Na+/K+ pump restores balance of electrolytes
ADH acts to... Correct Answers increase water permeability of
distal tubules and collecting duct
aerobic metabolism Correct Answers presence of oxygen,
pyruvic acid is converted to acetyl-CoA in the mitochondria,
then ETC; generates a net 34 ATP
aldosterone Correct Answers causes increased sodium
reabsorption into blood, increasing osmolality, causing water to
enter blood and equalize concentration
alleles Correct Answers different forms of the same gene
anaerobic metabolism Correct Answers glycolytic pathway
which occurs in cytoplasm, utilizes glucose; oxygen isn't
present, so pyruvic acid is converted to lactic acid; produces 2
ATP
, angiotensin II Correct Answers causes vasoconstriction leading
to increased BP; causes release of aldosterone
apoptosis Correct Answers programmed cell death to remove
injured, worn out cells; phagocytes will engulf cell fragments;
carried out by proteolytic enzymes (caspases)
atrophy Correct Answers decrease in cell size, number of cells
unchanged; promotes cell survival by decreasing energy
requirements; caused by disuse, denervation, ischemia etc.
autosomal dominant Correct Answers single mutant allele is
transmitted to offspring; 50% chance of transferring
autosomal recessive Correct Answers both chromosomes must
possess mutant allele to display disease; heterozygous is a
carrier; all offspring will be carrier
cell membrane Correct Answers semipermeable membrane/
lipid bilayer which separates intra/extracellular environment,
provides receptors for hormones, conducts electric currents,
enables cell to cell recognition
cytoplasm Correct Answers colloid solution inside cell which
surrounds organelles
cytoskeleton Correct Answers maintains cell shape using
microtubules and microfilaments
