KAPLAN NURSING ENTRANCE EXAM-SCIENCE, MATH, READING AND GRAMMAR Science
What would cause a decrease in red blood cells
Inadequate intake of iron
Sodium and Potasium
help regulate the body's water balance and also play a significant role in musclecontraction
Action potential
Na rushing in (depolarization) followed by slow Ca entry (continued
depolarization) followed by K leaving (repolarization). Contraction will occur after action potential
What is responsible for the regulation of PH in the body?
Urinary System
What increases the basal metabolic rate in adults?
Stress
What effect does asthma have on the lungs?
Inflames and narrow the bronchioles and airways while INCREASINGMUCUSPRODUCTION
What controls the body's immune response?
white blood cells (lymphocytes)
Rate and depth perception in a normal adult
Chemoreceptors in response to the acid base oxygen status
Principal function of blood flow to the cardiac system
To provide oxygen and remove carbon dioxide and waste product
Parasympathetic nervous system
HR would be 56bpm ad rest would be 20bpm
Human BP increases signals are sent to the brain slowing down the heart andhelping the BP to return to the normal is an example of
negative feedback loop
How is oxygen and carbon dioxide exchanged through red blood cells?
Diffusion
How do electrolytes exchange between interstitial fluid and external interstitial
fluid?
Osmosis
How do your brain cells differ from other cells in the body?
Brain cells do not store glucose as glycogen
What controls the firing of the SA node to trigger the spark of the cardiac cycle?Autonomic nervous system (ANS)
Chronic hypertension would cause what changes in the blood vessels?
Damage to the arterioles resulting in increased blood flow through the bloodvessels. The body's ability to correct an excess or deficit of a metabolic acid depends onnormal function of what system?
Renal system
