NSG 510 EXAM Prep Questions With Correct Answers. WBC count should be - answer5-10K ~15K normalvolemia - answerthey have enough volume in their vessels maintain a normal presure inside those vessels -so they maintain a normal blood pressure - normal blood pressure 90/60 to 120/60 Normal stroke volume what is stroke volume - answer70ml the mount of blood pumped out of the ventricle per beat hypovolemia - answertoo little ECS to maintain blood pressure can because by a loss of blood such as hemorraging, vomiting or diaariahea essential any loff of fluids When a vessel is constricted what happens to the resistance and blood pressure - answerwe increase the resistance and that raises the blood pressure during vasodialation - answerblood cells get smaller and you decrease your blood resistance so there for blood pressure decreases Amount of WBC in blood - answer5-10K ~15 EXAM STUDY MATERIALS July 29, 2024 12:59 PM Good perfusion - answerhaving good blood flow to organs and muscles -without good perfusion (flow to muscles) you will have exercise intolerance How do we know if the kidneys are working - answerUrine analysis amount of normal urine - answerAdult .5ml per kg if everyone weighs 60kg so 30ml per hour neonates and infants - 1-2ml per kg per hour hypotensive blood pressure for adult - answerlowest adult blood pressure 90/60 Tachycardia - answerfast heart rate 100 BPM relative hypertension - answerwhen you decrease someones blood pressure by vasodialting when they normally had high blood pressure (150/100) that person will experience bad symptoms when we lower their blood pressure peripheral resistance - answerrelated to the diameter of blood vessels -increase resistance and increase blood pressure -decrease resistance and decrease blood pressure Normal HR - answer60-100 BPM HCT level in the blood - answer35-45 ~40 If you have poor brain perfusion - answerlightheaded dizzy unconscious EXAM STUDY MATERIALS July 29, 2024 12:59 PM When kidneys sense low blood pressure like in a hypovolemic person - answer-Kidneys reabsorb their filtrate to help restore blood volume a -decreased blood volume -increases blood concentration How do you know id a baby is hypovolemic - answer-if fontanelle in ababy is depressed they may have low volume How do you determine how much volume a baby put out? - answermeasure diaper before and after then use formula to convert findings to pounds hypervolemia - answer-causes congestion in the organs -in a normal person the volume of blood would increase, pulse would be strong, kidneys would produce urine, weight would go up a bit heart failure - answerwhen the left ventricle does not pump a sufficient volume of fluid -kidneys not working -poor gas exchange -fluid in the alveoli beceause of congestion -then fluid can build up in jugular vein -can determine that this person is hypovolemic -kidneys will detect the hypocolemis and reabsorb fluid causing even more fluid to build up and worsesning the problem heart attack - answernot enough blood perfusing through coronary artery and muscles loose blood When left ventricle has low stoke volume - answer-blood becomes congested in the heart -gas exchange slows in the lungs and aveloi -can affect venous side of circulation -can cause the jugular veign to become congested how do we test for edema - answer
