A patient diagnosed with Heart Failure would like the nurse to explain what the diagnosis means.
How will the nurse explain heart failure?
The heart muscle cannot pump effectively, causing a backup of blood.
Increased protein leads to reduced oncotic pressure and inability to pull the fluid into the system.
The hydrostatic pressure pushing fluids out of the capillary is lower than the oncotic pressure.
The decrease in venous pressure from the backup of blood increases hydrostatic pressure.
The Correct Answer is A
Choice A rationale
Heart failure occurs when the heart muscle cannot pump blood effectively, leading to a backup of blood and fluid buildup in the lungs, legs, and other parts of the body. This explanation is accurate and helps the patient understand the nature of their condition.
Choice B rationale
Reduced oncotic pressure due to increased protein levels is not a primary factor in heart failure. Heart failure is related to the heart’s inability to pump effectively, not protein levels affecting oncotic pressure.
Choice C rationale
Hydrostatic pressure pushing fluids out of the capillaries is not directly related to heart failure. In heart failure, the issue lies in the heart’s inability to pump blood efficiently, leading to fluid buildup rather than fluid being pushed out of capillaries.
Choice D rationale
The decrease in venous pressure from the backup of blood does not cause heart failure. Heart failure results from the heart’s inability to pump blood effectively, leading to increased pressure and fluid buildup, not a decrease in venous pressure.

Explanation
Choice A rationale
Ergotamine does not increase hypoperfusion. It is used to constrict blood vessels to reduce blood flow.
Choice B rationale
Ergotamine does not decrease hypoperfusion. It is used to constrict blood vessels to reduce blood flow.
Choice C rationale
Ergotamine does not increase hyperperfusion. It is used to constrict blood vessels to reduce blood flow.
Choice D rationale
Ergotamine decreases hyperperfusion by constricting blood vessels in the basilar artery vascular bed, reducing the blood flow to relieve migraine headaches. .
