At 32 weeks' gestation, a woman is scheduled for a second nonstress test (following the one she had at 28 weeks' gestation). Which response by the patient would indicate an adequate understanding of this procedure?
1. "I can't get up and walk around during the test."
2. "I'll have an IV started before the test."
3. "I must avoid drinks containing caffeine for 24 hours before the test."
4. "I need to have a full bladder for this test."
Correct Answer: 1
Rationale 1: The purpose of the nonstress test is to determine the results of movement on fetal heart rate. The patient will have to lie still on her side during the procedure.
Rationale 2: There is no IV needed to administer medications.
Rationale 3: Caffeine might cause the infant to be more active and cause the test to go more quickly.
Rationale 4: Patients usually are asked to have their bladders full only for ultrasounds.
