Which of the following is a primary purpose of hemodynamic monitoring?
To measure respiratory rate and lung function
To evaluate kidney function and urine output
To assess the functioning of the cardiovascular system
To assess acid-base levels in the blood
The Correct Answer is C
A. Measuring respiratory rate and lung function is part of respiratory assessment, not the focus of hemodynamic monitoring.
B. Kidney function and urine output are influenced by hemodynamics but are not directly measured by hemodynamic monitoring.
C. Hemodynamic monitoring is primarily used to assess cardiovascular function, including parameters like cardiac output, preload, afterload, and systemic vascular resistance. It helps guide fluid and medication therapy in critically ill patients.
D. Acid-base status is assessed via arterial blood gases, not hemodynamic monitoring.

Correct Answer is C
Explanation
A. Electrical burns are often severe and can cause significant tissue damage, so they are not typically minor.
B. Electrical burns usually cause more than just reddened or purplish skin; blistering and deeper damage are common.
C. Electrical burns often cause extensive damage beneath the skin that is much greater than what is visible on the surface, due to the current traveling through deeper tissues.
D. While true that damage beneath the skin can be extensive, this choice is somewhat redundant and less precise than C, which clearly states the extent of hidden injury.
Correct Answer is B
Explanation
A. Decreased heart rate is not a direct complication of invasive pressure monitoring.
B. Infection at the insertion site is a common and serious potential complication of invasive pressure monitoring, such as with arterial or central venous lines. Strict aseptic technique is essential to reduce this risk.
C. Elevated body temperature may occur with infection, but it is not specific to the invasive monitoring procedure itself.
D. Increased blood pressure is a hemodynamic finding, not a complication of the monitoring process.
