  1. What is included in the respiratory system and why is it important?
    The upper airway, lungs, lower airway and alveolar sacs.

    It is important in helping the body meet the need for oxygenation and tissue perfusion because the source of the oxygen for all body cells is the air we breathe.
  2. Functions on the respiratory system
    Ventilation- movement of air in and out of lungs.

    Compliance

    Surface tension

    Musclular Effort

    Resistance
  3. Oxygen affinity is related to what?
    pH

    PCO2

    Body Temperature
  4. How much do you breathe in and out of your lungs every minute?
    6 liters of air.
  5. What is the process in the oxygenation of blood?
    1. Deoxygenated blood goes to the right side of the heart to the lungs.

    2. The lungs oxygenate blood.

    3. Oxygenated blood goes to the left side of the heart.

    4. Oxygenated blood is them pumped to the tissue in the body.
  6. What are the three steps of oxygenation?
    • Ventilation
    • Perfusion
    • Diffusion

    -All organs, nerves, and muscles of the respiratory tract must be intact.
  7. What are the interfering factors with oxygenation?

  79. Hyponatremia
    Na level below 136 mEq/L.

    Sodium imbalances often occur with fluid volume imbalances because the same hormones regulate both sodium and water balance.
  80. Problems caused by hyponatremia
    Excitable Cell Membrane Depolarization- depends on high ECF levels of sodium being available to cross cell membranes and move into cells in response to a stimulus. It makes depolarization slower so that excitable membranes are less excitable.

    Osmolarity of the ECF is lower than the ICF. Water moves into the cell, causing swelling. Large amounts of swelling can make the cell burst and die. (lysis)
  81. What does ECF consist of?
    • Blood, lymph, connective tissue, water, bone.
    • 1/3 of body water weight
  82. What does ICF consist of?
    • 2/3 of body water weight.
    • fluid within the cells
  83. Hypernatremia
    • serum sodium level > 145 mEq/L.
    • Can be caused by or can cause changes in fluid volume. As sodium level rises, there is a larger difference between ECF and ICF.

    More sodium is present to move rapidly across cell membranes during depolarization, making excitable tissues more easily excited. This is called irritability.

    Water moves from the cell into the ECF to dilute the hyperosmolar ECF.

    When serum sodium levels are high, severe cellular dehydration occurs.
  84. Potassium
    • Major cation of ICF.
    • Regulate protein synthesis and glucose use and storage.
    • has some control over intracelular osmolarity and volume.
    • Highest in meat, fish, veggies and fruit. Lowest in eggs, bread and cereal grains.
    • 2-20 g/day.
    • Occurs through kidney function. 80% of potassium is moved thorugh the body with the kidneys. It is enhanced by aldosterone.
  85. Sodium-potassium pump
    • Is the main controller of ECF potassium level.
    • The pump moves extra sodium ions from the ICF and moves extra potassium ions from the ECF back into the cell.
    • The serum potassium level remains low and the cellular potassium level remains high. This also keeps the serum sodium level high and cellular sodium level low.
  86. Causes of hyponatremia
    diaphoresis, loop diuretics, NPO
  87. S/S of hyponatremia

  117. Nursing implications for hypercalemia
    • Monitor for pulmonary edema
    • EKG

    • toxic dig level
    • hydrate pt
    • strain urine
    • assess for flank pain
  118. Meds to treat hypercalcemia
    • Rocaltrol or Calcijex (calcifediol)
    • PO4 binders
    • IV calcium chloride or calcium gluconate
    • Ca chlorids is 3x the doase of Ca gluconate. dilute in D5W
  119. Causes of hyperohosphatemia
    • Renal failure
    • extra intake of PO4
    • tumor lysis during chemo
    • laxative
  120. S/S of hyperphosphatemia
    • tetany
    • seizures
    • circumoral parathsia
    • muscle spasms
  121. Nursing implication for hyperphosphatemia
    • seizure precautions
    • Notify MD is S/S increase
    • phosphate binders
    • dialysis
    • Ca supplement
  122. Causes of hypermagnesemia
    • high Mg intake
    • decreased renal excretion
  123. S/S of hypermagnesemia
    • bradycardia
    • peripheral vasodilation
    • hypotension
    • EKG changes
    • at risk for cardiac arrest
    • drowsy
    • lethargic
    • reduced or absent DTR
    • weakness of muscles
  124. Meds to treat hypermagnesemia
    IV magnesium sulfate or calcium
  125. Fluid Volume Deficit
    • decreased skin turgor
    • oliguria
    • dry membranes
    • tachycaradia
    • hypotension
    • weight loss
  126. Isotonic Dehydration
    hypovolemia

    • labs look normal
    • shock
    • poor urine output
  127. Hypotonic Dehydration
    Greater electrolytes lost

    • diluted electrolytes
    • increased labs
    • neurological changes because of swelling
  128. Hypertonic dehydration
    Greater H2O loss

    • pittin gedema
    • increase sensation of thirst
    • hyperactive DTR
    • Bun Creatinine and Albumin levels are increased
  129. Fluid Volume Deficit
    • Edema
    • neck and hand vein distension
    • crackles in lungs
    • pale and cool skin
    • hypertension
    • full and bounding pulse
    • weight gain
  130. Isotonic Overhydration
    Hypervolemia

    • labs look normal
    • 3-5 lbs daily is cause for concern
    • risks for CHF and pulmonary edema (life threatening)
  131. Hypotonic Overyhydration
    • water intoxication
    • swelling
    • neuro changes
  132. Hypertonic Overhydration
    • Cells shrink
    • cause by high sodium intake
    • has pitting edema
  133. Urine Specific Gravity
    1.015-1.025
  134. BUN
    8-25 mg/dL
  135. Creatinine
    • 0.6-1.5 mg/dL
    • better for renal function than BUN
  136. Blood glucose
    70-110 mg/dL
