A nurse is caring for a client who is at 41 weeks of gestation and has a positive contraction stress test. For which of the following diagnostic tests should the nurse prepare the client?
Percutaneous umbilical blood sampling
Amnioinfusion
Biophysical profile (BPP)
Chorionic villus sampling (CVS)
The Correct Answer is C
Choice A Reason:
Percutaneous umbilical blood sampling (PUBS) is not appropriate. This invasive procedure involves sampling blood from the umbilical cord and is not typically used in the context of a positive contraction stress test.
Choice B Reason:
Amnioinfusion is not appropriate. Amnioinfusion is a procedure in which sterile fluid is infused into the amniotic cavity to alleviate conditions such as oligohydramnios. It is not a primary diagnostic test for assessing fetal well-being.
Choice C Reason:
Biophysical profile (BPP) is appropriate. The biophysical profile is a diagnostic test that assesses the well-being of the fetus by evaluating various parameters, including fetal heart rate, fetal breathing movements, fetal movements, fetal tone, and the amniotic fluid volume. This test provides additional information to assess fetal well-being and can help guide decisions about the timing and mode of delivery.
Choice D Reason:
Chorionic villus sampling (CVS) is inappropriate. CVS is a prenatal test used for diagnosing certain genetic conditions but is not indicated in the context of a positive contraction stress test.

Correct Answer is C
Explanation
Choice A Reason:
"I will get injections of the medication once daily until my labor stops." Terbutaline is typically administered as a subcutaneous injection or orally, but the frequency can vary. It is often given as needed or on a scheduled basis, depending on the healthcare provider's instructions. However, "once daily until labor stops" is not a typical approach.
Choice B Reason:
"My blood sugar may be low while I'm on this medication." While terbutaline can affect glucose metabolism, it is more commonly associated with hyperglycemia (high blood sugar) rather than hypoglycemia (low blood sugar).
Choice C Reason:
"I will have blood tests because my potassium might decrease." Terbutaline, a beta-2 adrenergic agonist, can potentially lead to hypokalemia (a decrease in potassium levels). Monitoring potassium levels through blood tests is important during terbutaline therapy.
Choice D Reason:
"My blood pressure may increase while I'm on this medication." Terbutaline is known to cause cardiovascular side effects, but an increase in blood pressure is not a common effect. It is more associated with tachycardia (increased heart rate) and potential hypotension. Monitoring blood pressure is still important, but an increase is less likely compared to other cardiovascular effects.
Correct Answer is B
Explanation
A. Contractions that last 45 seconds each with a 3-minute rest between contractions are less common. Typically, contractions last around 60 seconds during active labor.
B. Contractions that last for 60 seconds each with a 3-min rest between contractions is the expected pattern.
During active labor, contractions are commonly around 60 seconds in duration, and they occur approximately every 4-5 minutes.
C. Contractions that last for 60 seconds each with a 4-min rest between contractions are not consistent with the usual pattern of contractions in active labor. A 4-minute rest between contractions would be an extended interval.
D. A contraction that lasts for 4 minutes followed by a period of relaxation is not typical and may indicate a problem. Normal contractions usually last around 60 seconds or less.
