A nurse in a clinic is discussing contraceptive methods with a client. Which of the following methods should the nurse recommend as having the lowest failure rate?

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.

A) Correct - Chronic hypertension is a significant risk factor for developing preeclampsia during pregnancy. Preeclampsia is characterized by high blood pressure and organ damage, typically occurring after 20 weeks of pregnancy.
B) Incorrect- Maternal age of 30 years is not a specific risk factor for preeclampsia.

However, maternal age over 40 is considered a risk factor.

C) Incorrect- A prepregnancy BMI of 19 falls within the healthy weight range and is not typically associated with an increased risk of preeclampsia.
D) Incorrect- Having a third pregnancy is not inherently a strong risk factor for preeclampsia. Women experiencing their first pregnancy are at a slightly higher risk.
