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 B

Explanation

Positioning the transducer level with the phlebostatic axis is a crucial step in accurate hemodynamic monitoring. The phlebostatic axis is an imaginary reference point located at the fourth intercostal space, mid-anterior/posterior chest. Placing the transducer at this level ensures that the pressure measurements obtained are reflective of the patient's true hemodynamic status.
A. Positioning the limb with the catheter insertion site at the level of the transducer in (option A) is incorrect because: While it is important to position the limb appropriately to avoid kinks or occlusions in the catheter tubing, this is not directly related to the accurate measurement of hemodynamic parameters.
C. Ensuring that the patient is lying with the head of the bed flat for all readings in (option C) is incorrect because The position of the patient's head does not directly impact the accuracy of hemodynamic monitoring unless it specifically relates to changes in preload or intracranial pressure monitoring.
D. Balancing and calibrating the hemodynamic monitoring equipment every hour in (option D) is incorrect because: While it is important to ensure that the monitoring equipment is calibrated and functioning properly, doing so every hour may not be necessary. Calibration frequency may vary based on institutional policies and patient stability.
Therefore, the correct action that demonstrates effective teaching about hemodynamic monitoring is positioning the transducer level with the phlebostatic axis.

A. Tachypnoea B. Heart blocks C. Vomiting D. Bradycardia E. Hypotension

Correct Answer is A

Explanation

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.
