    A) single dose antacid
    B) multiple antacid dosing
    C) repeated dosing with concurrent opioid administration (e.g. during labor)

    A) true
    B) false

Question # 12 (Multiple Choice) Concerning nonparticulate antacids and their use in preoperative medication:

    A) may themselves produce pulmonary damage if aspiration gastric fluid containing this type of an acid occurs
    B) more effective than colloidal antacids suspensionsin increasing gastric acid pH
    C) both
    D) neither

Question # 13 (Multiple Choice) Ondansetron (Zofran) probably mediates its antiemetic effects by interacting with this receptor system:

    A) muscarinic, cholinergic
    B) nicotinic, cholinergic
    C) dopaminergic
    D) serotonergic
    E) GABA

Question # 14 (True/False) In adults: relatively high risk of pulmonary complications if aspiration volume is greater than 25 ml and pH < 2.5:

    A) true
    B) false

Question # 15 (Multiple Answer) Physiological effects of metoclopramide (Reglan):

    A) stimulates upper gastrointestinal motility
    B) increases gastroesophageal sphincter tone
    C) increases gastric fluid pH
    D) increases gastric acid secretion

Question # 16 (Multiple Choice) Drugs that may offset metoclopramide (Reglan) effect on the upper GI tract:

    A) opioids
    B) concurrent atropine administration
    C) both
    D) neither

Question # 17 (Multiple Choice) Greater "lag time" in increasing gastrointestinal pH:

    A) antacids
    B) H2 blockers
    C) both about the same lifetime
