A child is brought into the emergency department.
After assessing a child's airway, breathing and circulation (ABCs), which of the following would the nurse do next?

Choice A rationale

Drawing blood for a type and crossmatch is a crucial step in preparing for potential blood product administration, but it is not the first action in managing a pediatric patient presenting with signs of shock. Immediate priorities involve securing vascular access to deliver intravenous fluids and medications to reverse the state of hypoperfusion.

Choice B rationale

Establishing a suitable intravenous (IV) site is the paramount first step in managing a patient in shock, especially hypovolemic shock from a broken arm, as it allows for immediate, rapid volume replacement with isotonic crystalloid fluids. Restoring intravascular volume is the primary goal to improve perfusion, making vascular access the initial life-saving priority.

Choice C rationale

Hyperventilation, which refers to an increased rate and depth of breathing, can lead to respiratory alkalosis and is not generally indicated for managing hypovolemic shock due to trauma unless there is evidence of severe head injury with signs of cerebral herniation. The immediate treatment for hypovolemic shock is fluid resuscitation, not manipulating respiratory rate.

Choice D rationale

While providing analgesics is important for pain management, it is a secondary intervention. Administering oral analgesics to a patient who is showing signs of shock is dangerous because compromised circulation can impair absorption, and the priority must remain the stabilization of hemodynamic status through fluid resuscitation via IV access.

Choice A rationale

A blood pressure of 130/90 mm Hg in a child with a history of hypertension may be elevated, but this is a chronic condition and, without more acute signs of end-organ damage or crisis, is not as immediately life-threatening as a potential cardiac event.

Choice B rationale

An infant with difficulty feeding and a temperature of 100.1 degrees F (38 degrees C) has a low-grade fever and feeding issues, which warrant attention but do not indicate immediate physiological instability or a critical compromise of oxygenation or perfusion.

Choice C rationale

An adolescent with coarctation of the aorta (a congenital narrowing of the aorta) and reports of a runny nose and coughing likely has an uncomplicated upper respiratory infection, which is a non-urgent issue compared to other potential cardiac instability.

Choice D rationale

A toddler with Tetralogy of Fallot squatting quietly is experiencing a hypercyanotic spell (tet spell) in which squatting is an instinctive compensatory mechanism that increases systemic vascular resistance, thereby decreasing right-to-left shunting and improving pulmonary blood flow, indicating a critical need for immediate intervention to prevent severe hypoxia.
