NR 283 Week 5 eDapt; Homeostasis and Elimination

Homeostasis and Elimination Fluid Imbalances What occurs during osmosis? Water moves from an area of lower solute concentration to an area of higher solute concentration. Which hormones will the body use when there is too much fluid (fluid overload) or too little fluid (dehydration)? Select all that apply. 2286009969500Antidiuretic hormone Atrial natriuretic peptide Aldosterone Hypovolemia: Blood is lost due to hemorrhage and poor fluid intake. Maldistribution of fluid: Movement of fluid from one compartment to another without a loss of fluid Hypervolemia: Too much fluid accumulates and/or organs in the body are unable to manage or excrete. After being out at the beach for hours, an adult suffered from an extensive sunburn covering their back, arms, and legs. Which fluid imbalance is this person most likely experiencing? Hypovolemic fluid imbalance You suspect someone may have hypervolemia. Which tests would most accurately support this? Daily weight Electrolytes: Intravenous fluids used by healthcare professionals rely on sodium concentrations to treat conditions of fluid imbalance. Blood pressure: Receptors throughout the body that send signals to the autonomic nervous system to constrict or dilate blood vessels depending on the fluid imbalance it may sense. Protein: Low levels can cause movement of fluid into interstitial areas, causing edema. For example, low levels can cause a water leak from the vascular area into the surrounding tissue, causing edema. Hormones: Renin is converted to angiotensinogen to cause vasoconstriction. It also stimulates production of aldosterone by the adrenal gland, which helps to keep fluid in the vascular system. Categorized conditions based on type of fluid imbalance: ypovolemia: blood loss from external injury dehydration extensive burns aldistribution: systemic inflammatory response syndrome anaphylactic reaction transfusion reaction ypervolemia: heart failure liver failure (cirrhosis) renal failure 228600374015Lack of potable water in a small town Regular daily temperature is 120 degrees Fahrenheit Concentration of bisphenol A in food containers 00Lack of potable water in a small town Regular daily temperature is 120 degrees Fahrenheit Concentration of bisphenol A in food containers Which environmental factors directly affect fluid balance? Select all that apply. 228600332105Total body water differences Kidney function Weight and height 00Total body water differences Kidney function Weight and height Which risk factors make older adults and children more sensitive to fluid imbalances? Select all that apply. Electrolyte Imbalances Which statement is the best definition of electrolytes? Ions in bodily fluids that regulate metabolic processes 228600339090Calcium Magnesium Potassium Sodium 00Calcium Magnesium Potassium Sodium Which electrolytes have a positive charge? Select all that apply. When dissolved in water or bodily fluids, electrolytes will conduct (not diffuse or suppress) electricity. Cations (not pions or avions), such as sodium (Na) and magnesium (Mg), are positively charged ions. Anions (not scions or inions), such as bicarbonate (HCO3) and chloride (Cl), are negatively charged ions. An adult has lost water through sweating while mowing the yard in the middle of a hot summer day. Unfortunately, the person did not keep water nearby to replace what was being lost. Based on this history, which serum sodium level would most
