4Which of the following drugs acts to suppress the cough reflex?
- AA) ASA
- BB) Codeine
- CC) Meperidine
- DD) Acetaminophen
- EE) Phenyibutazone
5Morphine binds to which site to produce analgesia?
- AA) By binding to specific receptors in the CNS
- BB) By decreasing the influx of sodium
- CC) By decreasing the synthesis of prostaglandins
- DD) By decreasing nerve activatin at the site of injury
6Morphine causes vomiting by
- AA) A direct irritant action on the gastric mucosa
- BB) Stimulation of the nodose ganglion of the vagus nerve
- CC) Stimulation of the medullary chemoreceptor trigger zone
- DD) Direct stimulation of the gastrointestinal musculature
7The decrease in ventilation caused by morphine, meperidine and some of the related opioids depends chiefly upon
- AA) Depression of cortical activity
- BB) Peripheral blockade of chemoreceptor impulses
- CC) An increase in carbon dioxide concentration in the blood
- DD) Blockade of afferent autonomic impulses from the lungs
- EE) Loss of sensitivity of the medullary respiratory center to carbon dioxide
8Small doses of barbiturates and morphine depress respiration primarily by
- AA) A parasympathominetic action
- BB) Inhibiting the Herine-Bueuer reflex
- CC) Rendering the aortic chemoreceptor system insensitive to O2
- DD) Rendering the respiratory center in the brain stem less sensitive to changes in CO2
- EE) A specific effect at myoneural junctions of phrenic and intercostal nerves
9Which of the following are pathognomonic symptoms of narcotic overdose?
- AA) Miosis, coma and depressed respiration
- BB) Mydriasis, coma and smooth muscle spasms

- AA) Codeine
- BB) Methadone
- CC) Naloxone
- DD) Meperidine
- EE) Pentazocine
12A heroin-dependent patient should NOT be given nalbuphine (Nubain) for pain because
- AA) It has no analgesic properties
- BB) It may produce respiratory depression
- CC) As a mixed agonist-antagonist, it can elicit withdrawal symptoms
- DD) The high abuse potential of nalbuphine may add to the patient's problems

- BB) Pentazcine
- CC) propoxyphene
- DD) Indomethacin
- EE) Acetaminophen
- FF) None of the above
14Which of the following statements does NOT characterize pentazocine?
- AA) It is equianalgesic with codeine
- BB) It is a partial opioid antagonist
- CC) Its abuse potential is less than that of heroin
- DD) It may induce dysphoria and mental aberrations
- EE) It is effective only on parenteral administration
15The antagonist of choice in the treatment of opioid overdosage is
- AA) Naloxone
- BB) Nalorphine
- CC) Pentazocine
- DD) Levallorphan
- EE) Propoxyphene
16Which of the following is a complete antagonist of the opioid receptor and the agent of choice in the treatment of narcotic overdose?
- AA) Naloxone
- BB) Nalorphine
- CC) Cyclazocine
- DD) Levallorphan
- EE) None of the above
17Methadone is used in detoxification (drug withdrawal) of patients physically dependent on morphine because methadone
- AA) Precipitates withdrawal reactions
- BB) Antagonizes the depressant actions of morphine
- CC) Will not in itself produce physical dependence
- DD) Withdrawal reactions are less intense and stressful than those of morphine

- BB) Methadone
- CC) Alphaprodine
- DD) Pentazocine
- EE) Meperidine
