A nurse is caring for a client who is at 41 weeks of gestation and has a positive contraction stress test. For which of the following diagnostic tests should the nurse prepare the client?

The correct answer is C. Place the client in a lateral position.

A. Elevating the client's legs is not the priority in this situation. Placing the client in a lateral position is more appropriate to improve blood flow and prevent supine hypotension.

B. Notifying the provider is an important action but not the immediate priority. Addressing the client's position and blood pressure is crucial before contacting the provider.

C. Placing the client in a lateral position is the priority nursing action.

The low blood pressure may be due to aortocaval compression (supine hypotension) caused by the weight of the uterus on the vena cava. Turning the client onto her side alleviates this compression and helps improve blood flow.

D. Monitoring vital signs every 5 minutes is important, but the immediate action should be to address the client's position and blood pressure. Continuous monitoring and further interventions can follow.

A. Decreased vaginal discharge is not typically associated with the onset of labor. In fact, an increase in vaginal discharge may be observed as the cervix begins to soften and efface.

B. Weight gain of 0.5 to 1.5 kg is not a specific sign that precedes labor. Weight gain during late pregnancy is more related to fluid retention, and it does not necessarily indicate imminent labor.

C. Urinary retention is not a common sign that precedes labor. However, increased pressure on the bladder from the descending fetus may lead to more frequent urination rather than retention.

D. A surge of energy is known as the "nesting instinct" and is a common sign that precedes labor. Some women experience a burst of energy and motivation to prepare for the upcoming birth.
