A nurse is assisting in the care of a client who is in active labour. The nurse notes variable decelerations of the FHR. The nurse should identify which of the following is a cause of variable decelerations.

Choice A rationale:

The nurse should schedule a 3-hour oral glucose tolerance test (OGTT) for the client because the blood glucose levels taken 1 hour following a meal are higher than the expected range for gestational diabetes. This test will help to diagnose and assess the client's glucose tolerance and determine if there is gestational diabetes or any other potential glucose regulation issues.

Choice B rationale:

Increasing carbohydrates to 65% of daily nutritional intake is not the appropriate action in this situation. It may lead to further elevation of blood glucose levels, which can be detrimental for a client with gestational diabetes. The goal is to manage blood glucose levels and prevent complications, so recommending a higher carbohydrate intake would be counterproductive.

Choice C rationale:

Obtaining an HbA1c (glycated hemoglobin) is not the most suitable action in this scenario. HbA1c provides an average of the blood glucose levels over the past few months, which is more helpful for diagnosing and monitoring chronic diabetes, rather than gestational diabetes, which is temporary and occurs during pregnancy. An OGTT is a more appropriate test for gestational diabetes assessment.

Choice D rationale:

Reinforcing instruction about insulin administration is not warranted at this point since there is no information indicating that the client is currently on insulin therapy. Additionally, using insulin as the first step in the management of gestational diabetes is not common practice. Lifestyle modifications, dietary changes, and other measures are usually attempted first.

Choice A rationale:

The nurse should monitor the urinary output of the client as it can be an important indicator of hydration and renal function. However, in this specific scenario, the administration of oxytocin via IV infusion after a vaginal delivery requires a different focus for evaluating medication effectiveness.

Choice B rationale:

The nurse should primarily assess the fundal consistency to evaluate the effectiveness of oxytocin. Oxytocin is often administered after childbirth to promote uterine contractions and prevent postpartum hemorrhage. Checking the fundal consistency helps determine if the uterus is contracting appropriately. A firm fundus indicates effective contractions, which are essential for controlling bleeding and preventing complications.

Choice C rationale:

Monitoring the pulse rate is a vital aspect of patient care, but it may not be the most relevant parameter to evaluate the effectiveness of oxytocin. Pulse rate can give information about the client's cardiovascular status and general well-being, but it does not directly assess the medication's impact on uterine contractions.

Choice D rationale:

Similarly, keeping an eye on blood pressure is crucial for patient safety and detecting potential issues like hypertension. However, it is not the primary parameter for evaluating the effectiveness of oxytocin. Blood pressure monitoring is essential for overall health assessment but does not directly relate to the medication's intended effect.
