Pharmacology Chapter 24 through 27
Show Answers:

  1. primary neurotransmitter in the sympathetic branch of the autonomic nervous system.
  2. produce activity similar to the neurotransmitter norepinephrine.
    adrenergic drugs
  3. Another name for adrenergic drugs is _________ (i.e., mimicking the actions of the sympathetic nervous system) drugs
  4. The ___________ branch is regulated by involuntary control.
  5. the _______ branch control over a person's heart rate, breathing rate, and ability to divert blood to the skeletal muscles
  6. The purpose of stimulating the sympathetic (adrenergic) nerves is to divert blood flow to the vital organs so that the body can deal with a stressful situation.
  7. In general, adrenergic drugs produce one or more of the following responses in varying degrees:
    CNS? Autonomic nervous system? Heart? Metabolism?
    • CNS - wakefulness, quick reaction to stimuli, quickened reflexes
    • Autonomic nervous system—relaxation of the smooth muscles of the bronchi; constriction of blood vessels, sphincters of the stomach; dilation of coronary bloodvessels; decrease gastric motility
    • Heart—increase in the heart rate
    • Metabolism—increased use of glucose (sugar) anci liberation of fatty acids from adipose tissue
  8. Adrenergic nerves have either alpha (a) or beta (b) receptors. Drugs that act on the receptors are called selective or nonselective. Adrenergic drugs may be selective (act on a or b receptors) or nonselective (act on a and b receptors)
  9. Adrenergic drugs have a variety of uses and may be given for treatment of the following;
    Hypovolemic and septic shock; Moderately severe to severe episodes of hypotension; Control of superficial bleeding during surgiclal and dental procedures of the moiith, nose, throat and skin; Cardiac decompensation and arrest; Allergic reactions; Temporary treatment of heart block
  10. Adrenergic drugs are important in the care and treatment of
    patients in shock.
  11. To counteract the symptoms of shock, the body initiates physiologic mechanisms release of
    epinephrine and norepinephrine
  12. Short acting B2 Agonists (SABA — Adrenergic or Sympathomimetics Used for Acute Respiratory Symptom relief
    • epinephrine - Adrenalin, Epinephrine Mist, Primatene Mist
    • Albuterol - Proventil, Ventolin
    • levalbuterol - Xopenex
  13. Long Acting Agonists (LABA - Adrenergic or Sympathomimetics used for long term respiratory management)
    salmetrol - Serevent Diskus
  14. ______ is contraindicated in pt who are hypotensive from blood volume deficits.
  15. _________ causes severe hypertension in the patient who is lying down (supine);
  16. Drug-specific nursing diagnoses are the following: Adrenergic or Sympathomimetics drugs
    • Ineffective Tissue Perfusion
    • Decreased Cardiac Output
    • Disturbed Sleep Pattern
  17. If a pt has marked hypotension, the administration of a _________ is required
