What is the main hemodynamic parameter that measures preload?

Systolic Blood Pressure.

Mean Arterial Blood Pressure.

Central Venous Pressure (CVP).

Systemic Vascular Resistance.

Answer and Explanation

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 (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.

A. Show the patient that her leg is gone B. Administer the prescribed pain medication C. Explain and educate the patient that the pain is real D. Tell the patient that it is not possible to feel pain in her toes

Correct Answer is B

Explanation

Choice A reason: Showing the patient that her leg is gone does not address the immediate concern of pain management.

Choice B reason: Administering the prescribed pain medication is the first step in managing phantom pain, which is a common experience for amputees.

Choice C reason: While it is important to validate the patient's experience of pain, the first action should be to address the pain medically.

Choice D reason: Telling the patient that it is not possible to feel pain in her toes is incorrect and dismissive of the phenomenon of phantom pain.
