A nurse is planning to reinforce nutritional teaching with a client who is in her first trimester of pregnancy. The nurse should recommend an increase in which of the following nutrients to support an increase in maternal blood volume during pregnancy?

Rationale:

A) Incorrect - Applying oxygen is not the priority action in the case of excessive vaginal bleeding and a boggy uterus. Oxygen therapy would be appropriate if there were signs of respiratory distress or decreased oxygen saturation, but it does not directly address the primary concern of uterine atony and bleeding.
B) Incorrect - Administering methylergonovine might be appropriate, but the priority is to address the uterine atony with fundal massage first. Fundal massage helps stimulate uterine contractions and control bleeding, which is crucial in this scenario.
C) Incorrect - Encouraging the client to empty her bladder is important, but it is not the first action to take in the case of excessive bleeding and uterine atony. Immediate intervention to control the bleeding takes precedence.
D) Correct - Initiating fundal massage is the priority action in this situation. A boggy uterus with excessive vaginal bleeding indicates uterine atony, which is a potentially life-threatening condition requiring immediate intervention to prevent further bleeding.
Fundal massage helps the uterus contract and control bleeding. Addressing uterine atony is critical to prevent further hemorrhage and stabilize the client's condition.

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.
