Following a minor motor vehicle collision, a client at 36-weeks gestation is brought to the emergency center.She is lying supine on a backboard, is awake, and denies any complaints.
Her blood pressure is 80/50 mmHg and her heart rate is 130 beats/minute.
Which action should the nurse implement first?
Infuse 1,000 mL normal saline using a large bore IV.
Obtain a blood sample for a complete blood count.
Tilt the backboard sideways to displace the uterus laterally.
Palpate the abdomen for contractions.
The Correct Answer is C
Choice A rationale
Infusing 1,000 mL normal saline using a large bore IV is a good response to increase the client's blood volume and improve blood pressure, but it should not be the first action. The immediate priority is to relieve the compression of the inferior vena cava caused by the gravid uterus, which is decreasing blood return to the heart and causing hypotension.
Choice B rationale
Obtaining a blood sample for a complete blood count is important for assessing the client's overall health and identifying any possible complications, but it does not address the immediate life-threatening issue of hypotension caused by the gravid uterus compressing the inferior vena cava.
Choice C rationale
Tilting the backboard sideways to displace the uterus laterally is the correct first action. This maneuver helps to relieve the compression of the inferior vena cava by the gravid uterus, thereby improving blood return to the heart, increasing cardiac output, and normalizing blood pressure.
Choice D rationale
Palpating the abdomen for contractions is important to assess for potential labor or uterine irritability, but it does not address the immediate need to relieve the compression of the inferior vena cava causing hypotension.

Correct Answer is D
Explanation
Stopping oxygen per cannula after uterine hyperstimulation and subsequent contraction reduction is not appropriate. Oxygen should be continued to ensure fetal oxygenation, particularly after a period of stress caused by frequent contractions. Discontinuing oxygen too soon may compromise fetal well-being.
Choice B rationale
Checking for clonus in both feet is unrelated to the management of uterine contractions post-oxytocin administration. Clonus assessment is used in evaluating neuromuscular function, often in conditions such as preeclampsia, but not for monitoring uterine activity or response to oxytocin.
Choice C rationale
Notifying the nursery about the client's response is important for continuity of care but does not address the immediate need to manage the uterine contractions. The primary focus should be on stabilizing uterine activity before updating other departments.
Choice D rationale
Restarting the oxytocin infusion rate per protocol is the correct intervention after ensuring that the contractions have reduced to a safe frequency and duration. This approach helps to maintain labor progress while minimizing the risk of hyperstimulation and fetal distress. The nurse should follow the hospital's guidelines for oxytocin titration.
Correct Answer is B
Explanation
Choice B rationale
Informing the anesthesia care provider is the priority action. Ingesting coffee within a few hours before surgery can affect anesthesia management, and the anesthesia team needs to be aware of any potential complications.
Choice A rationale
Starting the IV is important but not the priority in this scenario. The anesthesia care provider needs to be informed first.
Choice C rationale
Contacting the obstetrician is also important but comes after informing the anesthesia care provider.
Choice D rationale
Ensuring preoperative lab results are available is essential, but the first step should be to inform the anesthesia care provider about the coffee intake.
