The ICU nurse provides care for a 67-year-old female patient experiencing a distributive shock. Assessment findings are indicative of decreasing cardiac output, decreased peripheral perfusion, and increased capillary permeability. The nurse identifies that the patient is in which stage of shock.

Progressive stage

Compensatory stage

Initial stage

Refractory stage

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is A

Explanation

This pathway represents the normal sequence of electrical impulses that coordinate the contraction and relaxation of the heart chambers.
The electrical signal originates from the sinoatrial (SA) node, which is often referred to as the natural pacemaker of the heart. It is located in the right atrium and generates the electrical impulses that initiate each heartbeat. From the SA node, the electrical signal travels to the atrioventricular (AV) node, which is located at the junction between the atria and ventricles.
After passing through the AV node, the electrical impulse travels through the bundle of His (also known as the atrioventricular bundle) and divides into the right and left bundle branches. These branches continue the conduction pathway and deliver the electrical signal to the Purkinje fibers.
The Purkinje fibers spread the electrical impulse rapidly throughout the ventricles, stimulating the contraction of the ventricular muscle and allowing for efficient pumping of blood out of the heart.
Therefore, the correct sequence of the normal conduction pathway in the heart is:
A. SA node - AV node - bundle of His - bundle branches - Purkinje fibers.

A. Red blood cells B. Clotting factors C. Platelets D. White blood cells

Correct Answer is B

Explanation

Fresh frozen plasma (FFP) is a blood product that contains various clotting factors, including factors II, V, VII, VIII, IX, X, XI, and XIII. These clotting factors are essential for the normal coagulation process. In patients with shock, coagulation abnormalities can occur, and administration of FFP can help replenish the deficient clotting factors and restore proper coagulation function.
The other options mentioned are not the primary components replaced by fresh frozen plasma:
A. Red blood cells are in (option A) is incorrect because Red blood cells carry oxygen and are typically replaced by packed red blood cell transfusions in cases of significant blood loss or anemia. Fresh frozen plasma does not contain a significant amount of red blood cells.
C. Platelets in (option C) is incorrect because: Platelets play a role in blood clotting and are typically replaced by platelet transfusions in cases of thrombocytopenia or platelet dysfunction. Fresh frozen plasma may contain a small number of platelets but is not the primary source for platelet replacement.
D. White blood cells in (option D) is incorrect because White blood cells are part of the immune system and are not typically replaced using fresh frozen plasma. Fresh frozen plasma does not contain a significant amount of white blood cells.
Therefore, fresh frozen plasma is primarily administered to patients in shock to replace clotting factors and help restore proper coagulation function.

Correct Answer is A

Explanation

Patients in shock receive fresh frozen plasma to replace which one of the following?

Correct Answer is B

Explanation

Which conditions can cause hypovolemic shock? Select all that apply.

A 48-year-old female patient with septic shock presents with a BP of 70/46, pulse 136, respirations 32, temperature 104.0° F, and blood glucose of 246 mg/dl. The following have been ordered. Which order will the nurse accomplish first?

To verify the correct placement of an endotracheal tube (ET) after insertion, the best initial action by the nurse is to:

A 78-kg patient with septic shock has a urine output of 30 mL/hr for the past 3 hours. The pulse rate is 120/minute and the central venous pressure and pulmonary artery wed pressure are low. Which order by the health care provider will the nurse question?

The emergency department nurse is assessing a patient who is in the compensatory stage of hypovolemic shock. Which manifestations does the nurse expect? Select all that apply.

An arterial catheter is inserted in the right radial artery to monitor a patient's blood pressure. Which information obtained by the nurse indicates that a complication of arterial pressure monitoring may be occurring?

A 40-year-old female patient with massive trauma and possible spinal cord injury is admitted to the emergency department (ED). The nurse suspects that the patient may be experiencing neurogenic shock in addition to hypovolemic shock, based on which one of the following?

A student is caring for a patient who suffered massive blood loss after trauma. How does the student correlate the blood loss with the patient's mean arterial pressure (MAP)?
