Patient PreparationQuestion 81 of 100
During a 3-hour glucose tolerance test the patient vomits 20 minutes after drinking the glucose solution. What is the correct action?
a.Give a second glucose drink and restart the timing
b.Notify the provider or laboratory immediately, since the test usually must be discontinued and rescheduled
c.Continue the collections and note the vomiting on the last tube
d.Shorten the test to one hour
Explanation
Vomiting means the glucose load was not absorbed, so the remaining timed results are meaningless and the provider or laboratory decides whether to stop and reschedule. Repeating the drink is not the phlebotomist's decision and doubles the dose risk. Continuing the draws or arbitrarily shortening the protocol produces uninterpretable data.
