What is the main hemodynamic parameter that measures preload?
Systolic Blood Pressure.
Mean Arterial Blood Pressure.
Central Venous Pressure (CVP).
Systemic Vascular Resistance.
The Correct Answer is C
Choice A reason: Systolic Blood Pressure is not a direct measure of preload; it indicates the pressure in the arteries during the contraction of the heart muscles.
Choice B reason: Mean Arterial Blood Pressure is an average blood pressure in an individual during a single cardiac cycle, but it does not specifically measure preload.
Choice C reason: Central Venous Pressure (CVP) is a direct measure of the blood volume returning to the heart and the ability of the heart to pump the blood into the arterial system, making it a key indicator of preload.
Choice D reason: Systemic Vascular Resistance refers to the resistance to blood flow offered by all of the systemic vasculature, excluding the pulmonary vasculature, and is not a measure of preload.

Explanation
Choice A reason: Recording the client's intake and output is important but not the highest priority in an unconscious patient following a cerebral hemorrhage.
Choice B reason: Performing passive range of motion exercises is a lower priority compared to maintaining a patent airway.
Choice C reason: Suctioning saliva from the client's mouth is the highest priority to maintain airway patency and prevent aspiration, which is critical for an unconscious patient.
Choice D reason: Monitoring the client's electrolyte levels is important but secondary to immediate life-saving interventions such as maintaining airway patency.
