The emergency department nurse reviews the medical record of a 41-year-old male patient with hemorrhagic shock, which contains the following information.
Physical Assessment Findings Pulse 140 beats/min and thready
Diagnostic Findings ABG respiratory acidosis
Blood pressure 60/40 mm Hg Respirations 40/min and shallow
Lactate level 7 mmol/L
All of these provider prescriptions are ordered for the patient. Which does the nurse carry out first?
Give Plasmanate 1 unit now.
Prepare for endotracheal intubation.
Give normal saline solution 250 mL/hr.
Type and crossmatch for 4 units of packed red blood cells (PRBCs).
The Correct Answer is C
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 C
Explanation
The nurse should listen over both lung fields to ensure that air entry is present bilaterally, indicating that the tube is correctly positioned in the trachea. This comes after observing chest movements.
B. Using an end-tidal CO2 monitor to check for placement in the trachea in (option B) is incorrect because End-tidal CO2 monitoring can provide confirmation of correct tube placement in the trachea by detecting exhaled CO2 levels. However, it requires additional equipment and setup, which may not be readily available at the bedside or immediately accessible.
C. Observing the chest for symmetrical movement with ventilation is the initial action after placing an endotracheal tube.
D. Obtaining a portable chest radiograph to check tube placement (option D) is incorrect because Chest radiographs are commonly used to confirm endotracheal tube placement, especially for long-term confirmation or if there are concerns about placement. However, obtaining a portable chest radiograph may involve delays and is not the initial action to be taken for immediate verification.
Therefore, the best initial action by the nurse to verify the correct placement of an endotracheal tube (ET) after insertion is to auscultate for the presence of bilateral breath sounds.
Correct Answer is B
Explanation
Lactate is a by-product of anaerobic metabolism that accumulates when there is insufficient oxygen supply to meet cellular metabolic demands. In the context of severe tissue hypoxia, such as in septic shock, the body may resort to anaerobic metabolism, leading to increased lactate production and elevated lactate levels in the blood.
Elevated lactate levels, typically above 4.0 mmol/L, are indicative of tissue hypoxia and inadequate oxygenation at the cellular level. Higher lactate levels, such as 9.0 mmol/L, suggest more severe tissue hypoxia and increased anaerobic metabolism.
A. Partial thromboplastin time (PTT) 64 seconds in (option A) is incorrect because: PTT is a laboratory test that evaluates the intrinsic pathway of the coagulation cascade. While coagulation abnormalities may occur in septic shock, PTT alone does not specifically indicate severe tissue hypoxia.
C. Potassium 2.8 mEq/L (2.8 mmol/L) (option C) is incorrect because Low potassium levels (hypokalemia) can be a concern in septic shock, but it does not directly indicate severe tissue hypoxia.
D. PaCO2 58 mm Hg in (option D) is incorrect because: PaCO2 refers to the partial pressure of carbon dioxide in arterial blood and is a measure of the respiratory status. While an elevated PaCO2 can be a sign of respiratory acidosis, it is not specific to severe tissue hypoxia.
Therefore, in a critically ill patient with septic shock, an elevated lactate level, such as 9.0 mmol/L, indicates severe tissue hypoxia and inadequate oxygenation at the cellular level
