  1. How can fever cause dehydration?
    excessive fluid loss due to diaphoresis
  2. Other than dehydration, fever causes what two things?
    • increased metabolism
    • increased demand for O2
  3. Irritability and restlessness are early signs of _________  _________.
    cerebral hypoxia
  4. A s/s of pneumonia that is not reliable in older adults.
    abrupt onset of fever with shaking & chills
  5. S/S of pneumonia in addition to fever.
    • productive cough with pain
    • rapid, bounding pulse
    • crackles
    • increased WBC
    • hypoxemia (ABG)
    • decreased SPO2
  6. S/S of pneumonia in older adults.
    • confusion
    • lethargy/malaise
    • anorexia
    • increased RR & HR
  7. Wht are two things to be aware of with fever?
    • it causes diaphoresis which causes dehydration
    • it causes in increase in metabolism which increases O2 demand
  8. How much fluid is lost daily by lungs through evaporation?
    300-400 mL
  9. COPD patients are in chronic _______ with ______ compensating.
    • respiratory acidosis (↑O2, ↓CO2)
    • metabolic alkalosis (↑HCO3)
  10. What is a pink puffer?
    • Barrel chest due to use of accessory muscles to breathe with emphysema pts
    • Adequate intake of O2, just work harder
  11. What is a blue bloater?
    • insufficient O2 & cyanosis due to chronic bronchitis
    • right sided heart failure
  12. What to teach COPD pts about diet.
    • small, frequent meals
    • increase calories & protein
    • if still smoking, increase vit C
    • drink fluids BETWEEN meals, not with them (to avoid abdominal distention)
  13. What labs to monitor in COPD pts.
    • Mg++ & Ca++ (muscle contraction)
    • Mg++ & PO4- (bone mineralization; osteoporosis)
  14. Why is it important to offer mechanically soft diets for COPD pts?
    eating consumes energy needed for breathing
  15. O2 must bubble through a water solution to be humidified if given at what rate?
    • GREATER than 4L/min
    • (or, must be delivered directly to trachea)
  16. Four common symtoms of pneumonia that a nurse might note on a physical exam.
    • tachypnea
    • fever with chills
    • productive cough
    • bronchial breath sounds
  17. Four nursing interventions for pneumonia.
    • encourage deep breathing
    • increase fluids to 3L/day
    • use humidity to loosen secretions
    • suction airway to stimulate coughing
  18. How is hypoxia prevented during suctioning?
    deliver 100% O2 (hyperinflating) before and after each ET suction
  19. What physical findings are likely with an emphysema pt?
    • barrel chest
    • dry or productive cough
    • decreased breath sounds
    • dyspnea
    • crackles in lung fields
