NUR 110 Test 15 - Answer 2400-2700 mL/day 3. sensible loss of fluid

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)

Answer fluid outside the cells; includes intravascular and interstitial fluids 20% of body weight

• intravascular fluid

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

Answer

• Fluids dissolve and transport substances

• 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

Answer isotonic, hypotonic, hypertonic
