A school nurse is using the Weber's test to check a child's hearing acuity. Which of the following actions should the nurse take?

Answer: A

Rationale:

A. Frequent swallowing: Frequent swallowing in a postoperative tonsillectomy patient can be a sign of bleeding or a hemorrhage. This is a priority finding because it may indicate that the child is swallowing blood, which requires immediate intervention to prevent significant blood loss and complications.

B. Dark brown emesis: Dark brown emesis can be a normal finding post-tonsillectomy, as it may indicate the presence of old blood or clotted blood. While it should be monitored, it is not as urgent as frequent swallowing, which may signify active bleeding.

C. Sore throat: A sore throat is a common postoperative symptom following a tonsillectomy and is generally expected. It is important to manage pain and discomfort, but it is not as urgent as signs of potential bleeding.

D. Blood-tinged mucus: Blood-tinged mucus can occur after a tonsillectomy due to irritation or minor bleeding. While it should be observed, it is less critical compared to frequent swallowing, which may indicate more significant bleeding.

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.
