Which medication will the nurse administer to a client in the hyperdynamic phase of septic shock?
Heparin.
Clotting factors, platelets, and plasma.
Corticosteroids.
Vitamin K.
The Correct Answer is A
Choice A rationale
Septic shock in the hyperdynamic or warm phase involves systemic inflammatory response syndrome, which often triggers the coagulation cascade. This activation can lead to disseminated intravascular coagulation where microthrombi form throughout the microcirculation. Administering heparin during this early stage aims to inhibit the conversion of fibrinogen to fibrin, thereby preventing further microvascular occlusion and preserving organ perfusion before the compensatory mechanisms fail and progress into the hypodynamic or cold stage.
Choice B rationale
These blood products are typically reserved for the hypodynamic or late phase of septic shock when disseminated intravascular coagulation has progressed to a consumptive coagulopathy. At this point, the patient is at high risk for spontaneous hemorrhage due to the depletion of clotting factors and platelets. Providing these during the hyperdynamic phase is generally premature as the primary pathological process at that moment is excessive clotting rather than a deficiency leading to bleeding.
Choice C rationale
Corticosteroids are sometimes utilized in septic shock to manage relative adrenal insufficiency or to dampen the overwhelming systemic inflammatory response. However, they are not the primary medication indicated for managing the specific microcirculatory alterations seen during the hyperdynamic phase. Their role is more focused on hemodynamic stability through the enhancement of catecholamine sensitivity and reducing the production of pro-inflammatory cytokines, rather than directly addressing the risk of microthrombi formation.
Choice D rationale
Vitamin K is essential for the hepatic synthesis of clotting factors II, VII, IX, and X. While important for general coagulation health, it acts too slowly to address the acute, rapid-fire microvascular clotting occurring during the hyperdynamic phase of sepsis. It is not an intervention designed to treat the underlying pathophysiology of septic shock but is rather a nutritional supplement or an antidote for specific anticoagulants like warfarin.

Correct Answer is C
Explanation
Choice A rationale
This sequence incorrectly places obtaining vital signs (step 4) before securing airway and oxygenation. In trauma management, the primary survey must follow the ABC (Airway, Breathing, Circulation) sequence. Assessing vitals and inserting a Foley catheter are part of the secondary survey or the end of the primary survey. Failing to stabilize the airway and breathing before taking a full set of vitals could lead to patient deterioration in an emergency rollover scenario.
Choice B rationale
This sequence starts with vital signs, which violates the fundamental principles of trauma resuscitation. In a rollover accident, the nurse must first address life-threatening airway and breathing issues. Moving directly to removing clothing (step 5) before ensuring the patient is breathing or has a clear airway is inappropriate. The priorities must focus on immediate physiological stabilization before moving to assessment tasks that do not directly treat hypoxia or airway obstruction in the trauma patient.
Choice C rationale
This sequence correctly follows the trauma primary survey (ABCDE).
Step 1 assesses breathing, followed by step 7 to open the airway if needed.
Step 2 provides oxygen for breathing support.
Step 6 addresses circulation by starting IVs for fluid resuscitation.
Step 5 involves exposure to check for hidden injuries.
Step 4 obtains vitals once life-threats are managed, and step 3 (Foley) is a later intervention. This represents the most scientific and systematic approach to trauma care.
Choice D rationale
Starting the intervention by removing clothing (step 5) and taking vital signs (step 4) ignores the immediate life-saving needs of airway and breathing management. A patient in a rollover accident may have a compromised airway or tension pneumothorax. Delaying airway opening (step 7) and oxygen administration (step 2) while focusing on vitals and exposure increases the risk of hypoxic brain injury and cardiac arrest, making this sequence unsafe and clinically unsound.
Correct Answer is B
Explanation
Choice A rationale
Discussing sensitive hospital data or potential public health threats with family members violates patient confidentiality and professional boundaries. Family members do not have the expertise or authority to manage a potential chemical warfare scenario or a public health crisis. Such discussions could lead to unnecessary panic within the community without addressing the underlying clinical issue. Professional concerns must always be directed through the established institutional hierarchy to ensure a coordinated and legal response.
Choice B rationale
Reporting unusual patterns of illness to a supervisor is the first step in the chain of command for disaster management. The supervisor can validate the findings across different shifts and departments to determine if a formal alert is necessary. In the context of potential chemical exposure or biological threats, early reporting is essential for initiating decontamination protocols and notifying public health authorities. This action ensures that the hospital can mobilize resources and protect both staff and the public.
Choice C rationale
While the Centers for Disease Control and Prevention must eventually be notified of a potential mass casualty or chemical event, the individual nurse should follow the facility's internal notification policy first. Jumping directly to federal agencies can bypass local emergency management protocols and delay the immediate hospital-level response. The hospital administration and infection control departments are responsible for official communications with state and federal health agencies. Reporting to the supervisor ensures the information follows the correct legal channels.
Choice D rationale
Ignoring a significant increase in specific, severe symptoms like pulmonary edema and shortness of breath is a failure of clinical judgment and professional duty. Pulmonary edema involves fluid accumulation in the alveoli, which is a medical emergency and not a typical presentation of uncomplicated influenza. Nurses must remain vigilant for clusters of symptoms that suggest environmental or intentional harm. Dismissing these signs delays life-saving interventions and prevents the identification of a potentially larger public health catastrophe.
