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.

Choice D rationale
The Food and Drug Administration (FDA) is responsible for protecting public health by ensuring the safety, efficacy, and security of human and veterinary drugs, biological products, and medical devices through rigorous scientific testing. .
Correct Answer is A
Explanation
Choice A rationale
True, because antitussive agents, which are cough suppressants, can potentially lead to dependence due to their central nervous system effects. This risk is particularly concerning for patients with a history of addiction.
Choice B rationale
False, is incorrect because the potential for addiction does warrant caution when prescribing antitussive agents to patients with a history of addiction. .
