A nurse is caring for a client who had a vaginal delivery 1 day ago. The nurse determines that the client's fundus is firm, located 2 fingerbreadths above the umbilicus, and deviated to the left. Which of the following actions should the nurse take first?

A) Incorrect- Oxytocin is not typically administered during a nonstress test.

B) Incorrect- A nonstress test is used to assess fetal well-being and does not indicate Down syndrome.
C) Correct - A lateral tilt position (usually left lateral tilt) is recommended during a nonstress test to prevent compression of the vena cava and maintain proper blood flow to the uterus, which can optimize fetal heart rate monitoring.
D) Incorrect- NPO status is not typically required for a nonstress test. Nonstress tests are non-invasive and do not involve fasting.

Rationale:

A. Tachycardia is not a common or direct adverse effect of epidural anesthesia itself. While a rapid heart rate may occur secondary to maternal anxiety or as a compensatory response to hypotension, it is not the primary physiological marker for epidural complications. Heart rate typically remains stable or may decrease slightly as pain is relieved and sympathetic activity is modulated.

B. Fever is a documented potential adverse effect associated with epidural anesthesia, particularly during labor. The exact mechanism is multifactorial, potentially involving altered thermoregulation, reduced heat dissipation due to sympathetic blockade, or a non-infectious inflammatory response. Clinicians must distinguish this pharmacological pyrexia from maternal infection to ensure appropriate neonatal and maternal management following the delivery.

C. Tachypnea, or an increased respiratory rate, is generally not associated with epidural anesthesia. In fact, if the anesthesia level rises too high, it can lead to respiratory depression or a decreased rate due to the blockade of intercostal muscle nerves. Effective epidural analgesia usually promotes a more relaxed, normal breathing pattern by successfully alleviating the physiological stress and hyperventilation caused by acute pain.

D. Hypertension is the opposite of the expected vascular response to epidural anesthesia. The local anesthetic typically causes a sympathetic blockade, leading to peripheral vasodilation and a significant risk of maternal hypotension rather than high blood pressure. Monitoring blood pressure is a critical nursing priority because decreased systemic vascular resistance can compromise placental perfusion and lead to fetal heart rate decelerations.
