ch 16 self study review questions BAH!
Show Answers:

  1. describe the method for determining efficacy of pharmacologic treatment for a respiratory disorder
    • assessing the pts respirtory rate and qualities
    • observing the facial color for cyanosis
    • extrorla examination can be important to identify individuals with breathing difficulties
  2. what anatomical structures differentiate the upper respiratory tract from the LRT?
    • upper-nasal cavity, nasopharynx, and larynx
    • LRT-trachea, bronchi and lungs
  3. differentiate between the types of hypoxia. 4
    • hypoxic hypoxia-oxygen fails to reach the blood of lungs
    • stagnant hypoxia-failure to transport adequate oxygen to the tissues because of too little blood flow
    • anemic hypoxia-too little hemoglobin in the blood to transport oxygen to the tissues
    • histotoxic hypoxia-failure of the tissues to utilize oxygen even though adequate quantities are transported to them
  4. what is a serious problem of hypoxia
    dyspnea-air hunger as a result of some respiratory abnormality, causing the blood to be hypoxic or even more often too much carbon dioxide collects in body fluids
  5. identify actions of each drug therapy for the common cold
    • codeine-opiod antitussive
    • guaifenesin-enhances output of respriatory tract fluid by reducing adhesivesness and surface tension of respiratory secretions
  6. describe the clinical implications for the common cold
    viruses have incubation period of 1 to 4 days before symptoms begin to appear. actual shedding of virus usually precedes the onset of clincical symptoms by 1 to 2 days. WEAR A MASK and GLOVES
  7. identify the best management for allergic rhinitis
    eliminate the responsible allergen
  8. identify actions of drugs used to manage allergic rhinitis. what are the side effects of these agents/
    • antihistamines-drowsiness and dizziness
    • decongestants-arrhythmias, hypertension and nervousness
    • corticosteriods-epistaxis
    • mast cell stabilizers
    • anticholinergic agents
    • nonsteroidal antiinflammatory agents
    • leukotriene receptor antagonists
  9. what is the benefit of second generation antihistamines?
    lack substantial anticholinergic and sedative properites
  10. list dental drug interactions with antihistamines
    erythromycin, ketoconazole inhibit hepatic metabolism
  11. identify the actions of drugs used for vasomotor rhinitis and name a common adverse effect
    • humidified air
    • pseudoephedrine
    • sprays can result in taste disturbances
  12. identify medical treamtne to manage symptoms of laryngitis
    • acute-not talk or smoke to avoid irritating larynx (steam inhaltions, hot gargles and drinks to give relief) guaifenesin to remove viscous mucus
    • chronic-steam inalations, gargling with warm salt water, rest voice no smoking or alcohol
  13. list diseases that affect the LRT
    • asthma
    • bronchitis
    • emphysema
    • chronic obstructive pulmonary disease (COPD)
