The surgical ICU nurse is caring for postoperative clients at risk for hypovolemic shock. Which condition represents an early symptom of shock?
Tachypnoea
Heart blocks
Vomiting
Bradycardia
Hypotension
The Correct Answer is A
Tachypnoea, which refers to an increased respiratory rate, is an early symptom of hypovolemic shock. It is the body's compensatory response to inadequate tissue perfusion and decreased oxygen delivery. The increased respiratory rate is an attempt to improve oxygenation and maintain vital organ function.
B. Heart blocks in (option B) are incorrect because Heart blocks refer to disruptions in the electrical conduction system of the heart and are not specific to hypovolemic shock.
C. Vomiting in (option C) is incorrect because: Vomiting may occur in various conditions, including shock, but it is not exclusive to hypovolemic shock and can be present in other forms of shock or illnesses.
D. Bradycardia in (option D) is incorrect because Bradycardia, or a slow heart rate, is not typically an early symptom of hypovolemic shock. Instead, tachycardia (rapid heart rate) is more commonly observed as a compensatory response to maintain cardiac output.
E. Hypotension in (option E) is incorrect because Hypotension, or low blood pressure, can occur in hypovolemic shock but is generally considered a later-stage symptom. In the early stages, compensatory mechanisms may help maintain blood pressure, so hypotension may not be present initially.
F. Bradypnea in (option F) is incorrect because: Bradypnea refers to a slow respiratory rate, which is not typically an early symptom of hypovolemic shock. Tachypnoea, as mentioned earlier, is the more common early respiratory symptom.

Correct Answer is C
Explanation
Hemorrhagic shock is characterized by severe blood loss, leading to inadequate tissue perfusion and hypovolemia. The primary goal in the initial management of hemorrhagic shock is to restore intravascular volume and improve tissue perfusion. Administering intravenous fluids, such as normal saline solution, is a critical intervention to address hypovolemia and improve blood pressure.
A. Give Plasmanate 1 unit now in (option A) is incorrect because: Plasmanate is a plasma-derived product used to replace coagulation factors. While it may be necessary to address coagulation abnormalities, administering intravenous fluids to restore volume takes priority over specific blood products.
B. Prepare for endotracheal intubation in (option B) is incorrect because Endotracheal intubation may be required in cases of impending respiratory failure or compromised airway, but it should not be the first action in addressing hypovolemic shock.
D. Type and crossmatch for 4 units of packed red blood cells (PRBCs) in (option D) is incorrect because transferring packed red blood cells is an important intervention to address blood loss and improve oxygen-carrying capacity. However, before administering blood products, it is crucial to stabilize the patient's hemodynamics through fluid resuscitation.
Therefore, in a patient with hemorrhagic shock, the nurse's first priority among the given options is to give normal saline solution of 250 mL/hr to restore intravascular volume and improve tissue perfusion.

Correct Answer is A
Explanation
The stages of shock are commonly described as the initial, compensatory, progressive, and refractory stages. Here is an explanation of each stage and why the patient's assessment findings correspond to the progressive stage:
B. The compensatory stage in (option B) is incorrect because, In the compensatory stage, the body continues to activate compensatory mechanisms to maintain perfusion. This includes increased heart rate, peripheral vasoconstriction, and shunting of blood to vital organs. The patient's assessment findings of decreasing cardiac output, decreased peripheral perfusion, and increased capillary permeability suggest that the body's compensatory mechanisms are no longer sufficient to maintain perfusion adequately. Therefore, the patient has progressed beyond the compensatory stage.
C. The initial stage in (option C) is incorrect because, In the initial stage, there is an initial insult or injury that triggers the shock state. The body's compensatory mechanisms are activated, such as increased heart rate and vasoconstriction, to maintain blood pressure and perfusion. However, the patient's assessment findings indicate that they have progressed beyond the initial stage.
D. The refractory stage in (option D) is incorrect because The refractory stage represents a severe and irreversible state of shock where vital organs fail, and despite interventions, the patient's condition does not improve. The patient's assessment findings do not suggest the refractory stage, as there is still potential for intervention and management.
