A nurse is conducting a secondary assessment of a child who has experienced multiple trauma.

When inspecting the child's back which of the following would be most appropriate to do.

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

This statement is not the most accurate guideline for returning to school. While fading indicates healing, the crucial infectious period ends when the vesicles have dried and formed crusts. Waiting until complete fading of all lesions is an overly conservative and unnecessary measure that would extend the exclusion period beyond the time of non-infectivity. The virus is primarily spread via direct contact and airborne droplets until the crusting stage is complete.

Choice B rationale

Using a fixed period like ten days after initial lesions appear is an unreliable measure because the time course of the disease, especially the crusting phase, varies among individuals. The risk of transmission remains as long as moist, open vesicles are present, regardless of the number of days that have passed since the initial rash onset. The actual measure of non-infectivity is physical crusting.

Choice C rationale

This is the scientifically correct guideline. The child is no longer considered contagious with chickenpox (varicella) once all vesicular lesions have dried and crusted over, as the viral load in the lesions is significantly reduced. This usually takes about six to seven days after the rash onset. School exclusion policies are based on preventing the spread of the highly contagious varicella-zoster virus to others.

Choice D rationale

While a normal temperature is a sign of clinical improvement and resolution of the acute febrile illness, it does not confirm that the child is no longer contagious. The contagiousness is directly related to the presence of uncrusted lesions that contain infectious viral particles. A child may be afebrile but still have uncrusted, infectious lesions, making the return to school unsafe.
