NURSING 324 PHYSICS MODULE 5 QUIZ Which physiological or biological processes occur in the body through fluid dynamics? [Select all that apply] Correct! Circulation Correct Answer Respiration Correct! Lymphatic flow Correct Answer Digestion Circulation, respiration, lymphatic flow, digestion perspiration and urination are all physiological or biological processes occurring in the body through fluid dynamics. Question 2 0 / 1 pts Which factors determine the form of matter a particular substance will adopt? [Select all that apply] Correct! Temperature pH Correct Answer Pressure You Answered Chemical makeup Temperature and pressure determine the form of matter a particular substance will adopt. Chemical makeup and pH do not have an effect. Question 3 0 / 1 pts What is the defining characteristic of fluid as a substance? Fluid is a substance capable of freezing. Correct Answer Fluid is a substance capable of flow. Fluid is a substance capable of conduction. You Answered Fluid is a substance capable of evaporation. The defining characteristic of the substance fluid is the ability to flow. The ability to freeze, evaporate or conduct are not defining characteristics of the substance fluid. Question 4 1 / 1 pts What is the resistance to flow of a fluid called? Stable Unsaturated Saturated Correct! Viscosity The resistance to flow of a fluid is referred to the fluid’s viscosity. The saturated and unsaturated state of a fluid deals with the concentration of the fluid. The stability of a fluid has no effect on resistance. Question 5 1 / 1 pts Turbulent flow of fluid is favored by rapid flow velocity, low viscosity and whirlpool-like eddies. Correct! True False This is a true statement in contrast to laminar flow of a fluid that is favored by slow velocities and high viscosity. Question 6 0.5 / 1 pts Example(s) of Pascal’s Law that demonstrate external pressure being applied to a confined fluid being transferred equally to every point within the fluid are: [Select all that apply] Correct Answer Water running from the kitchen faucet. Correct! Administration of medication through a hypodermic needle. Correct Answer Administration of medication through an eye dropper. Correct! A hydraulic lift at the tire store. All are examples of the equal transfer of pressure to every point within the fluid when external pressure is applied to a confined fluid. Question 7 1 / 1 pts The statement: The amount of buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object describes which law of physics? Pascal’s Law Newton’s Law Correct! Archimedes Principle Poisseuille’s Principle The amount of buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object describes Archimedes Principle. Question 8 0 / 1 pts The application of Bernoulli’s equation for fluids can be applied to the person experiencing a transient ischemic attack (TIA) by which statement? Correct Answer The arterial constriction narrows the passage resulting in lowered blood pressure. The arterial expansion increases the passage resulting in lowered blood pressure. You Answered The arterial constriction narrows the passage resulting in increased blood pressure. The arterial expansion increases the passage resulting in increased blood pressure. The arterial constriction narrows the passage resulting in lowered blood pressure. This lower pressure will cause a temporary lack of blood flow to the brain which results in a transient ischemic attack (TIA). Question 9 0.67 / 1 pts Poisseuille’s Principle states the rate of flow of a fluid in a round tube depends on: [Select all that apply] Correct! Viscosity of the fluid. Correct Answer Pressure differences along the length of the tube. Velocity of the fluid. Correct! Dimensions the tube. The rate of flow of a fluid in a round tube depends on viscosity of the fluid, pressure differences along the length of the tube and the dimensions the tube. The velocity of the fluid is not a factor in Poisseuille’s Principle Question 10 1 / 1 pts What is the term for the maximum blood pressure when the heart is pumping? Correct! Systolic pressure Diastolic pressure Presystolic pressure Asystolic pressure The maximum blood pressure when the heart is pumping is referred to as the systolic pressure. The blood pressure when the heart is in the resting part of the cycle is called the diastolic pressure. Presystolic pressure is not a term that is used in regard to measuring blood pressure. Asystole is the absence of the pumping action of the heart.
