NURS 5461 Fluid Replacement
Questions and answers 100%
Pass
a. Fluid Replacement - CORRECT ANSWER-I/O equal ~1600mL/day
1. Total Body Water - CORRECT ANSWER-a. Adult males
i. < 65 y/o = 60%
ii. > 65 y/o = 50%
b. Adult females
i. < 65 y/o = 50%
> 65 y/o = 45%
Extracellular fluid volume - CORRECT ANSWER-1. 1/3 TWB
2. Controlled by Na retention and excretion
3. Water passively follows sodium
4. Body ignores ECF as a whole
a. Samples a portion of it EABV
, a. Effective Arterial Blood Volume - CORRECT ANSWER-b. Effective Arterial
Blood Volume
i. Volume in the arteries
ii. ~ 700ml
iii. Function of cardiac output and systemic vascular resistance
*Baro-receptors sense changes in the EABV
-Decreased EABV- increase release of catecholamines and increases CO and SVR,
activates RAAS, increased antidiuretic hormone secretion
-Increase EABV- suppresses RAAS, increase release of atrial natriuretic peptide
i. Manifestations of Dehydration/Volume Loss - CORRECT ANSWER-1. Thirst,
Delayed capillary refill
2. Dry mucous membranes, cool clammy skin
3. Tachypnea
4. Tachycardia with pulse > 100
5. Postural hypotension (SBP decrease > 20mmHg with standing)
6. Oliguria-calc based on wgt.
7. Depressed mental status of loss of consciousness
8. Peripheral cyanosis
