A nurse is caring for four children in an emergency department. Which of the following clients should the nurse assess first?

A. Placental abruption: Placental abruption is characterized by the premature separation of the placenta from the uterine wall before delivery of the fetus. Sudden, severe abdominal pain, moderate to severe vaginal bleeding, persistent uterine contractions, and uterine rigidity are classic signs and symptoms of placental abruption. Hypotension may occur due to hemorrhage, leading to decreased perfusion to vital organs.
B. Uterine rupture: Uterine rupture involves a tear in the uterine wall, which can lead to severe abdominal pain, vaginal bleeding, and signs of shock. However, uterine rupture typically occurs during labor or delivery, particularly in women with a history of uterine surgery or trauma.
C. Placenta previa: Placenta previa is characterized by the implantation of the placenta over or near the internal cervical os. It can cause painless vaginal bleeding in the third trimester, particularly after 20 weeks of gestation. However, it is not typically associated with severe abdominal pain or uterine rigidity.
D. Amniotic fluid embolus: An amniotic fluid embolus occurs when amniotic fluid, fetal cells, hair, or other debris enter the maternal circulation, leading to a potentially life-threatening reaction. Symptoms may include sudden dyspnea, hypotension, cardiovascular collapse, and disseminated intravascular coagulation (DIC). While it can cause severe complications, the symptoms described in the scenario are more consistent with placental abruption.

A. "Think about a positive outcome to a stressful situation." - This instruction describes a cognitive restructuring technique, which involves reframing negative thoughts with positive ones. While cognitive restructuring can be helpful for managing stress and anxiety, it is not specifically related to progressive relaxation.
B. "Tighten a muscle group, then release the tension and move to the next one." - This is the correct instruction for progressive relaxation. Progressive relaxation involves systematically tensing and relaxing muscle groups throughout the body to reduce physical tension and promote relaxation. By sequentially tensing and releasing muscle groups, the client learns to recognize and control muscle tension, which can help alleviate stress and anxiety.
C. "Focus on a pleasant memory and express your emotions in writing." - This instruction describes a journaling or expressive writing technique, which can be beneficial for processing emotions and reducing stress. However, it is not specific to progressive relaxation.
D. "Picture taking the stress you feel and pushing it down and out of your feet." - This instruction describes a visualization or imagery technique, where the client visualizes releasing stress from the body. While visualization can be a component of relaxation exercises, it is not specifically associated with progressive relaxation, which focuses on muscle tension and relaxation.
