A nurse in the newborn nursery is collecting data about a newborn's Moro reflex. Which of the following actions should the nurse take to elicit this reflex?

a. "The machine is programmed to prevent you from administering more than a safe dose."

When reinforcing teaching about epidural PCA (patient-controlled analgesia) with a client in active labor, it is important for the nurse to inform the client about the safety features of the machine. By explaining that the machine is programmed to prevent the client from administering more than a safe dose, the nurse reassures the client that they have control over their pain relief while minimizing the risk of overdose.

Option b, "During medication administration, you will not be able to move your legs freely," is not an accurate statement regarding epidural PCA. While epidural analgesia may cause temporary weakness or loss of sensation in the lower body, the ability to move the legs freely is not necessarily completely impaired. The degree of mobility can vary depending on the dosage and specific characteristics of the epidural.

Option c, "This method of pain control will shorten the second stage of labor," is not a valid statement. Epidural PCA is primarily used for pain relief during labor and delivery but does not directly affect the progression or duration of the second stage of labor, which involves pushing and the delivery of the baby.

Option d, "This type of anesthesia commonly causes a postpartum headache," is also incorrect. While headaches can occur as a potential side effect of epidural anesthesia, they are not specifically associated with epidural PCA. Postpartum headaches can have various causes and are not exclusively related to the use of epidural PCA.

By emphasizing the safety features of the machine and explaining that it prevents the administration of excessive doses, the nurse ensures that the client understands the appropriate use of the epidural PCA for pain control during labor.

The nurse should recommend that the client who has diminished breath sounds and paradoxical chest movement receive care first. This client is likely experiencing a tension pneumothorax, which is a life-threatening condition that requires immediate intervention.

Option a is incorrect because a client who has a head injury and whose pupils are fixed and dilated may have experienced brain death and may not be able to be resuscitated.

Option b is incorrect because a dislocated shoulder, while painful, is not immediately life-threatening. Option c is incorrect because a scalp laceration with intermittent bleeding can be managed with pressure and is not immediately life-threatening.
