Following surgery, a patient's central venous pressure (CVP) monitor indicates high pressures. Which action will the nurse anticipate taking?
Increase the IV fluid infusion rate.
Administer IV diuretic medications.
Elevate the head of the patient's bed to 45 degrees.
Document the CVP and continue to monitor.
The Correct Answer is B
Central venous pressure (CVP) is a measurement of the pressure in the central veins, which reflects the blood volume and right-sided cardiac function. High CVP readings may indicate fluid overload or impaired cardiac function, and intervention is necessary to address the underlying cause.
Administering IV diuretic medications can help reduce fluid volume by increasing urine output and promoting fluid elimination. By removing excess fluid, the diuretic medications can help lower the CVP and alleviate the high pressures.
The other options mentioned are not the anticipated actions for addressing high CVP:
A. Increasing the IV fluid infusion rate in (option A) is incorrect because: If the CVP is already indicating high pressures, increasing the IV fluid infusion rate would further contribute to fluid overload and exacerbate the problem. This action would not be appropriate for high CVP readings.
C. Elevating the head of the patient's bed to 45 degrees in (option C) is incorrect because Positioning the patient with the head of the bed elevated is commonly done to prevent complications such as aspiration or improve respiratory function. While it may have other benefits, it does not directly address the high CVP.
D. Documenting the CVP and continuing to monitor in (option D) is incorrect because Documenting the CVP and continuing to monitor is important for ongoing assessment and evaluation. However, in the presence of high CVP readings, intervention is necessary to address the underlying issue rather than solely documenting and monitoring.
Therefore, when a patient's CVP monitor indicates high pressures following surgery, the nurse would anticipate administering IV diuretic medications to help reduce fluid volume and lower the CVP.

Correct Answer is A
Explanation
The increased respiratory rate and pulse rate can be indicators of physiological changes or potential complications in the patient's condition. These changes may suggest alterations in tissue perfusion or other underlying issues that require further assessment.
Assessing the patient's tissue perfusion includes evaluating additional vital signs, such as blood pressure, oxygen saturation, and capillary refill time. Assessing skin color, temperature, and moisture, as well as peripheral pulses, can also provide important information regarding tissue perfusion.
B. Pain medication (option B) is incorrect because the increased respiratory and pulse rates could also indicate other factors that require assessment before administering pain medication.
C. Documenting the findings in the patient's chart (option C) is incorrect because it should not be the primary action at this point. Assessing the patient's condition and determining appropriate interventions take priority.
D. Increasing the rate of the patient's IV infusion (option D) is incorrect because may not be the most appropriate action without further assessment. The patient's increased respiratory and pulse rates may not necessarily be related to hydration status, and it is important to assess the patient comprehensively before making changes to the IV infusion rate.
Therefore, the best action by the nurse in this situation is to further assess the patient's tissue perfusion to gather more information and determine the appropriate course of action.
Correct Answer is A
Explanation
In the early stage of septic shock, the body initiates compensatory mechanisms to combat the infection and restore adequate tissue perfusion. Tachypnoea (rapid breathing) and tachycardia (elevated heart rate) are common early signs of septic shock.
Tachypnoea occurs as a response to increased metabolic demand and to compensate for impaired oxygenation and tissue perfusion. Tachycardia is the body's attempt to maintain cardiac output and compensate for decreased blood pressure.
B. Pallor and cool skin in (option B) is incorrect because Pallor and cool skin can occur in later stages of septic shock when perfusion to the peripheral tissues is compromised. However, they are not specific to the early stage.
C. Blood pressure 84/50 mm Hg in (option C) is incorrect because A blood pressure reading of 84/50 mm Hg indicates hypotension, which is typically seen in later stages of septic shock. In the early stage, blood pressure may still be within normal or slightly decreased range.
D. Respiratory acidosis in (optionD) is incorrect because: Respiratory acidosis refers to an imbalance in acid-base status and is not specific to the early stage of septic shock. Acid-base disturbances may occur at any stage of shock but are not indicative of the early stage.
