NUR 110 Test 15
- thirst center
Answer hypothalamus
- Average adult intake
Answer 2400-2700 mL/day
- sensible loss of fluid
Answer loss that is perceived or is measurable. (wound drainage, GI tract, urine)
- Insensible fluid loss
Answer Occurs daily through lungs and skin--cannot be measured for accurate output
- Intracellular fluid (ICF)
Answer fluid within cells (40% of body weight)
- Extracellular fluid (ECF)
- intravascular fluid
Answer fluid outside the cells; includes intravascular and interstitial fluids 20% of body weight
Answer the fluid found within the blood vessels 1 / 2
- interstitial fluid
Answer liquid found between the cells of the body that provides much of the liquid environment of the body
- functions of fluids
- Fluids dissolve and transport substances
Answer
- Fluids account for blood volume
- Fluids help maintain body temperature
- Fluids protect and lubricate body tissues
- Atrial natriuretic peptide (ANP)
Answer hormone secreted from atrial cells of the heart in response to atrial stretching and an increase in circulating blood volume. ANP has been identified as a diuretic that causes sodium loss and inhibits the thirst mechanism
- renin-angiotensin-aldosterone system
Answer group of hormones that regulate BP by excreting or retaining water and salt in response to a decrease in blood flow to the kidneys (hypotension)
- antidiuretic hormone (ADH)
Answer made in the hypothalamus and stored in the posterior pituitary gland. Released when there is a need to restore intravascular fluid
Fluid volume excess > ADH decreases Fluid volume decreases < ADH increases
- Types of fluids
- / 2
Answer isotonic, hypotonic, hypertonic
