NURS 171 UNIT 3 EXAM REVIEW
QUESTIONS AND CORRECT ANSWERS
Which are examples of health behaviors that affect overall status of health? ✅Tobacco
use
Sedentary lifestyle
Use of recreational drugs
Which dietary changes should the nurse instruct a client with hypertension to make to
control electrolyte and fluid balance? ✅Limit sodium intake
Increase calcium intake - prevent osteoporosis and maintain serum Ca/P levels
Increase potassium consumption
Which is true about tubing when administering lipids through the parenteral route?
✅Tubing must be changed after each bottle due to liquids being thick and viscous.
Which is a sensible fluid loss? ✅URINE OUTPUT
Perspiration
Weeping edema
Moisture in exhalation
BMR ✅amount of calories used by the body during a non-active period, AKA resting
energy expenditure
Ascorbic Acid ✅Vitamin that aids in tissue building and many metabolic reactions,
such as wound and fracture healing, collagen formation, adrenaline production, iron
absorption, conservation of folic acid, and cellular adhesion.
Molecules move across a membrane to equalize concentration. ✅Diffusion
Fluid moves across a membrane to equalize concentration. ✅Osmosis
Molecules move against a concentration gradient ✅Active Transport
Molecules move to equalize pressure. ✅Filtration
types of blood products that are available for transfusion ✅whole blood, red blood
cells, plasma, platelets, white blood cells, and plasma derivations
Which are the purposes of administering hypertonic IV solutions? ✅Stabilize blood
pressure.
Reduce edema.
, Increase urine output.
Symptoms:
Thirst
Rapid pulse
Muscle fatigue ✅Symptoms of Dehydration
PCO2
pH
HCO3 ✅Acid-base balance is reflected through which arterial blood gas values?
hypertonic solution ✅cells shrink - water from cells and into the intravascular (ECF)
D10W, D5W w/ 0.9 NaCl, D5W w/ 0.45 NaCl
hypotonic solution ✅Cells swell
from vascular system and into the cells
0.45% NaCl and 0.33 NaCl
Potassium ✅major electrolyte in ICF
transmit electrical impulses in multiple body systems
deficiency associated with increased BP, cardiac dysrhythmias, cardiac arrest and risk
of stroke, weakness
regulated by aldosterone
loss through vomiting, diarrhea and diuretics
potassium levels ✅3.5-5.0 mEq/L
sodium levels ✅135-145 mEq/L
Chloride ✅major electrolyte in ECF
essential for production of HCI for gastric secretion
functions as a buffer in oxygen-CO2 exchange in RBC's
assist with acid base balance
bounds to Na for acid base balance
Phosphate ✅major anion in ICF
promotes muscle nerve action
overall metabolism, formation of enzymes, acid-base balance
