Plasma osmolality - Study guides, Revision notes & Summaries

hydrostatic pressure - Answer pushing force exerted by water in the bloodstream. osmotic pressure - Answer pressure exerted by the solutes in solution. Most often electrolytes Oncotic pressure (colloid osmotic pressure) - Answer a form of osmotic pressure exerted by proteins, notably albumin, in a blood vessel's plasma (blood/liquid) that usually tends to pull water into the circulatory system. Normal albumin levels - Answer 3.1-4.3 g/dL osmolality - Answer the concentrati...

The nurse recalls blood plasma is located in which of the following fluid compartments? - Correct Answer Intravascular fluid A 35-year-old male weighs 70 kg. Approximately how much of this weight is ICF? - Correct Answer 42 L- the total volume of body water for a 70 kg person is about 42 L (60%) While planning care for elderly individuals, the nurse remembers the elderly are at ...

NU 545 UNIT 3 EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS LATEST UPDATE GRADED A++ How are water-soluble hormones transported? Water-soluble hormones are proteins that are polarized with a high molecular weight. Because they cannot diffuse across the lipid cell plasma membrane, they must interact or bind with receptors in or on the cell membrane to activate a second-messenger to mediate short-acting responses. How are lipid-soluble hormones transported? Lipid-soluble hormones diffus...

aldosterone is influenced by what? correct answerscirculating blood volume, blood pressure, plasma concentrations of sodium and potassium what is released when circulating blood volume of BP is decreased or sodium is decreased or potassium is increased? correct answersrenin is secreted and released by the kidneys renin stimulates the release of what? correct answersangiotensin water balance is primarily regulated by what? correct answersantidiuretic hormone (ADH, vasopressin) ADH sec...

Fluid regulation mechanisms - Answer--The thirst center. The thirst center in the hypothalamus stimulates or inhibits the desire for a person to drink. -Antidiuretic hormone. ADH regulates the amount of water the kidney tubules absorb and is released in response to low blood volume or in response to an increase in the concentration of sodium and other solutes in the intravascular fluids. -The RAAS. The RAA system controls fluid volume, in which when the blood volume decreases, blood flow t...
