A nurse is caring for a client who is in active labor and notes the FHR baseline has been 100/min for the past 15 min.
The nurse should identify which of the following conditions as a possible cause of fetal bradycardia?
Maternal hypoglycemia.
Maternal fever.
Chorioamnionitis.
Fetal anemia.
The Correct Answer is A
The correct answer is choice a. Maternal hypoglycemia.
Choice A rationale:
Maternal hypoglycemia can lead to fetal bradycardia, causing a sustained low fetal heart rate. Hypoglycemia in the mother can affect the fetus by reducing the availability of glucose, which is essential for fetal metabolism and heart function.
-
Choice B rationale:
Maternal fever is more commonly associated with fetal tachycardia rather than bradycardia. Fever in the mother can lead to an increased fetal heart rate, not a decreased one.
-
Choice C rationale:
Chorioamnionitis is an infection of the fetal membranes and amniotic fluid, which can lead to fetal distress and tachycardia rather than bradycardia.
-
Choice D rationale:
Fetal anemia can also cause bradycardia, but in this scenario, maternal hypoglycemia is a more immediate concern as it directly affects the fetal heart rate by impacting the fetal metabolic processes.

Correct Answer is D
Explanation
This is because after puncturing the skin and the vein, the nurse needs to advance the catheter into the vein with the finger hub to ensure proper placement and prevent complications such as infiltration or phlebitis.
Choice A is wrong because flushing the catheter with saline should be done after securing the catheter to the skin with a transparent dressing and attaching a primed piece of extension tubing to the catheter.
Choice B is wrong because retracting the stylet should be done after advancing the catheter into the vein and releasing the tourniquet from the client’s arm.
Choice C is wrong because releasing the tourniquet should be done after advancing the catheter into the vein and before retracting the stylet.
Correct Answer is B
Explanation
The correct answer is B.
Choice A reason: Atrial fibrillation is characterized by a rapid, irregular heartbeat and an absence of distinct P waves on the ECG, which is not indicated by the information provided.
Choice B reason: First-degree AV block is indicated by a prolonged PR interval without affecting the overall heart rate, aligning with the client’s PR interval of 0.24 seconds.
Choice C reason: Premature ventricular contraction would show an abnormal QRS complex on the ECG, which is not mentioned in the scenario.
Choice D reason: Sinus bradycardia is defined by a heart rate less than 60 bpm, which does not apply here as the client’s heart rate is 69/min, within the normal range of 60-100 bpm.
