A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?
aPTT
PT
INR
WBC count
The Correct Answer is A
- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.
- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.
- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.
- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

Correct Answer is B
Explanation
Choice A rationale:
Preeclampsia is not a contraindication for the administration of misoprostol for induction of labor. Misoprostol is a prostaglandin E1 analog used for cervical ripening and induction of labor. It is not contraindicated in patients with preeclampsia. However, its use should be carefully monitored in patients with hypertensive disorders of pregnancy due to the potential impact on blood pressure.
Choice B rationale:
Transverse fetal lie is a contraindication for the administration of misoprostol for induction of labor. Misoprostol should not be used when the baby is in a transverse position because it can lead to complications during delivery. Induction methods should be chosen carefully based on the fetal presentation to ensure a safe delivery process.
Choice C rationale:
Intrauterine growth restriction (IUGR) is not a contraindication for the administration of misoprostol for induction of labor. IUGR refers to a condition where a fetus does not grow at the expected rate inside the uterus. While the cause of IUGR needs to be addressed, misoprostol itself is not contraindicated in these cases. However, the healthcare provider should assess the overall fetal well-being before deciding on the induction method.
Choice D rationale:
Postterm pregnancy is not a contraindication for the administration of misoprostol for induction of labor. In postterm pregnancies, where the pregnancy has extended beyond 42 weeks, healthcare providers may consider inducing labor to prevent complications associated with prolonged gestation. Misoprostol is one of the options for induction in postterm pregnancies, although the choice of induction method may vary based on various factors.
