A woman in labour is receiving an oxytocin infusion. The uterine contraction pattern shows 5 contractions in 10 minutes, indicating uterine tachysystole. What is the next immediate nursing intervention?

Appeared in: NORCET 10 Mains

Explanation

Uterine tachysystole (more than 5 contractions in 10 minutes) is a complication of oxytocin that can reduce placental blood flow, leading to fetal hypoxia.
The immediate priority is to stop the oxytocin infusion. Oxytocin has a very short half-life (3-5 minutes), so stopping it provides the quickest way to reduce uterine activity.
Repositioning the patient, typically to a left or right lateral position, is a key intrauterine resuscitation measure that improves blood flow to the placenta.
These two actions, performed together, directly address the cause of the problem (oxytocin) and work to improve the fetal environment (repositioning).

Option A: Continuing the oxytocin infusion would prolong the period of excessive uterine contractions, worsening the risk of fetal distress and potential uterine rupture. Observation alone is not an active intervention.
Option B: Increasing the oxytocin dose is strictly contraindicated. It would exacerbate the tachysystole, severely compromising fetal oxygenation and increasing the risk of uterine rupture.
Option D: This is not the immediate nursing intervention. Intrauterine resuscitation measures (stopping oxytocin, repositioning, IV fluids, oxygen) must be attempted first to stabilize the fetus. An emergency C-section is a secondary step if these measures fail and fetal distress persists.

Clinical Relevance

Nursing practice connection: Use the key finding related to Management of Uterine Tachysystole during Oxytocin Infusion to guide bedside assessment, documentation, and the next nursing action.
Nurses are responsible for the continuous monitoring of patients on oxytocin. This includes assessing contraction frequency, duration, intensity, and fetal heart rate response.
Prompt recognition of uterine tachysystole and immediate initiation of corrective measures are critical nursing skills that can prevent fetal injury and adverse maternal outcomes.
This scenario highlights the importance of the nurse's autonomy in acting quickly to ensure patient safety by stopping the infusion before necessarily waiting for a physician's order.

How to Approach the Question

First, identify the clinical problem presented in the scenario. The question explicitly states '5 contractions in 10 minutes, indicating uterine tachysystole'.
Recognize that uterine tachysystole is a complication of the oxytocin infusion that can harm the fetus by reducing placental blood flow.
Apply the principle of priority interventions: the first step in managing a problem caused by a medication is to stop the medication.
Evaluate the options based on this principle. 'Stop oxytocin infusion' is the most direct and immediate action to address the cause.
Consider other immediate actions. Repositioning the patient is a standard intrauterine resuscitation technique to improve fetal well-being.
Select the option that combines the most critical immediate actions: stopping the causative agent and initiating resuscitation.

Concept Tested & Keywords

Concept Tested: Management of Uterine Tachysystole during Oxytocin Infusion
Stem keywords: oxytocin infusion, labour, uterine contraction, 5 contractions in 10 minutes, uterine tachysystole
Lead-in keywords: next immediate nursing intervention
Clinical cues: A contraction frequency of 5 in 10 minutes is the key sign of uterine tachysystole, an iatrogenic complication requiring immediate action.
