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.

Correct Answer is B
Explanation
Choice A rationale
A patient 3 days after surgery may still require higher doses of opioids for pain management, but the duration and intensity of postoperative pain typically decrease over time. This patient may not necessarily require a higher-than-expected dose compared to others.
Choice B rationale
Patients with cancer often experience severe and chronic pain due to the disease itself or its treatments. These patients may develop tolerance to opioids over time, necessitating higher-than-expected doses to achieve adequate pain relief.
Choice C rationale
Hypotension is a contraindication for high doses of opioids, as opioids can cause further blood pressure reduction. This patient would require careful dose adjustment to avoid exacerbating hypotension.
Choice D rationale
Patients with a concussion are at risk of altered mental status and respiratory depression from opioids. Therefore, higher doses are generally avoided to prevent worsening of these conditions.
Correct Answer is B
Explanation
Choice A rationale
Improved mental status can be a sign of better overall health but is not a specific indicator of improved heart failure status.
Choice B rationale
Using fewer pillows at night indicates reduced orthopnea, a common symptom of heart failure, suggesting that the patient’s heart failure status has improved.
Choice C rationale
Increased skin turgor indicates improved hydration status but is not a specific measure of heart failure improvement.
Choice D rationale
Heart rate regularity is important but does not directly indicate improved heart failure status.
