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.

Correct Answer is B
Explanation
Choice A reason: Requesting a job that requires sitting all day does not reflect an understanding of correct body mechanics or how to manage chronic back pain through activity.
Choice B reason: Beginning exercises to strengthen the lower back indicates that the patient understands the importance of muscle strength in supporting the spine and preventing back pain.
Choice C reason: Keeping the back straight while lifting is important, but the statement about lifting "heavy objects above my waist" suggests a misunderstanding, as lifting objects above the waist increases the risk of back injury.
Choice D reason: Sleeping with knees and back extended is not recommended for preventing back pain. It is better to sleep with knees slightly bent to maintain the natural curve of the spine.
Correct Answer is B
Explanation
Choice A reason (precautions): Droplet precautions are not the primary recommendation for Hepatitis A, as it is not primarily spread through droplets.
Choice B reason (precautions): Contact precautions are recommended for patients with Hepatitis A due to the risk of fecal-oral transmission, especially in a patient with incontinence.
Choice C reason (precautions): While standard precautions are always necessary, they are not sufficient alone for Hepatitis A, which requires additional precautions due to its mode of transmission.
Choice D reason (precautions): Airborne precautions are not required for Hepatitis A, as it is not spread through the air.
