What is shock? - Answer- inadequate tissue perfusion -the inability of the circulatory system to meet the nutritional needs , oxygen needs and waste removal demands of the body aerobic metabolism - Answer- -uses oxygen to convert sugar to energy -releases 36 ATP cells -CO2 and H20 are waste products anaerobic metabolism - Answer- -results from a oxygen poor environment -the body begins to burn sugar inefficiently -production of lactic acids -release 4 ATP cells -results in acid...

Drug Dilution Calculation correct answer: Drug % x 10 = number of mg in 1 mL of the drug. Step 1: drug % x 10 = # mg/mL. Step 2: # mg/mL x dosage ordered = number of mg of drug How many mg are in 3.0 mL of a 0.083% solution? correct answer: Step 1: 0.083 x 10 = 0.83 mg/mL. Step 2: 0.83 mg/mL x 3 mL = 2.5 mg Respiratory therapist is asked to administer 2.5 mg of Albuterol. medication is available in a 0.5% solution. How many mL of Albuterol should be administered? correct answer:...

True or false: Red blood cells do not have a nucleus. Ans: True Which of the following formulas represents the FICK equation? Ans: VO2 = Qxa - vO2 difference What is another name for red blood cells? Ans: Erthyrocytes The atrial contraction or 'Kick' accounts for what % of ventricular filling? Ans: 30% Which of the following describes cardiac output? Ans: SV x HR 2 What does erthyropoitein do? Ans: Regulates red blood cell production by stimulating bone marrow cells Which defines ...

• Initial signal to "drive" cardiovascular system comes from higher brain centers due to centrally generated motor signaling, fine tuned by feedback from - heart mechanoreceptors - muscle chemo receptors - muscle mechanoreceptors -Baroreceptors • Muscle mechanoreceptors sensitive to muscle metabolites (K+, lactic acid) -Exercise pressor reflex • Muscle mechanoreceptors sensitive to force & speed of motor movement • Baroreceptors detect changes in blood pressure • sudden...

ACSM Certified Exercise Physiologist Exam Questions With Verified Solutions | Latest Updates Physical Activity - ANSWER Any bodily movement produced by contracting skeletal muscles, with an increase in energy expenditure. Exercise - ANSWER Planned, purposeful, repetitive Physical Fitness - ANSWER Attributes or characteristics that individuals have achieved that related to their ability to perform physical activity 3 metabolic pathways the body uses to creates ATP - ANSWER 1....

Of the factors that can influence stroke volume, which do you think contributes to the rise in stroke volume during exercise? Increased afterload Increased contractility Increased heart rate All of the above - increased Contractility Based on the Krogh hydraulic model, which of the following would increase preload during exercise? Vasodilation of skin blood vessels Vasodilation of splanchnic blood vessels Vasodilation of skeletal muscle blood vessels None of the above - None of t...

Which of the following is the largest component of total energy expenditure (TEE)? A. RMR B. Thermic effect of digestion C. Physical Activity D. Metabolic Stress A. RMR The thermogenic effect of digestion is generally thought to contribute to no more than 10% to TEE. Activity contributes to 5% - 30% to TEE. With the exceptions of burn and sepsis, metabolic stress contributes to less than 50% TEE. However, in almost all situations, RMR constitutes 60% to 75% of TEE. Which of the fo...

What are the 3 key principles of training? - - overload - specificity - reversibility Describe the overload principle : - - a progressive & systematic application of greater work to the human body as the body becomes physiologically adapted to the pre-existing workload Describe the specificity principle : - - training effect is specific to: - muscle fibers recruited during exercise - energy system involved (aerobic vs. anaerobic) - velocity of concentration - type of contraction (eccent...

QP=pulmonary flow/QS=systemic flow= (AO sat - mixed venous sat)/ (Pulmonary vein sat - PA sat) -ANSWER Shunt equation [(AO mean-RA mean)/CO]x80 -ANSWER systemic vascular resistance (SVR) Dynes (125xBSA)/(AO sat- PA sat) x (Hgb x 1.34) x 10 -ANSWER Fick CO output (CO/SEPxHR)/(44.3x √mean gradient) -ANSWER Gorlin Aortic Valve area (CO/DFPxHR)/(37.7x√mean gradient) -ANSWER Gorlin Mitral Valve area CO/√Peak to peak gradient -ANSWER Hakki Formula CO/BSA The cardiac index *a...
