Which goal is a primary objective for a patient who has chronic heart failure (HF)?

Maximizing cardiac output.

Maintaining ideal body weight.

Performing daily aerobic exercises.

Maintaining a steady pulse oximetry reading.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Maximizing cardiac output is a primary goal for patients with chronic heart failure (HF) because it helps improve tissue perfusion and oxygen delivery to meet the body's demands. It is a crucial aspect of managing heart failure and preventing further complications.

Choice B rationale:

Maintaining ideal body weight is important for overall health but is not a primary goal specific to chronic heart failure management.

Choice C rationale:

While exercise is beneficial for heart failure patients, it needs to be tailored to the patient's condition. Performing aerobic exercises daily might not be suitable for all heart failure patients and is not a primary goal.

Choice D rationale:

Maintaining a steady pulse oximetry reading is important, but it is a measure of oxygen saturation in the blood and not a primary goal for managing chronic heart failure.

Correct Answer is D

Explanation

Choice A rationale:

Stenosis of the heart valves typically leads to murmurs and changes in heart sounds but does not directly impact blood pressure regulation.

Choice B rationale:

Decreased adrenergic sensitivity might lead to lower heart rate and blood pressure, not an increase in systolic blood pressure as seen in this case.

Choice C rationale:

Increased parasympathetic activity would lead to decreased heart rate, not an increase in systolic blood pressure as observed in the patient.

Choice D rationale:

Loss of elasticity in arterial vessels is the correct answer. With aging, arterial walls become less flexible and more rigid due to the accumulation of calcium and collagen. This loss of elasticity results in increased systolic blood pressure, which is the top number in a blood pressure reading. The diastolic pressure, represented by the bottom number, does not usually increase significantly with age. This change is a result of arteriosclerosis, which commonly occurs in elderly individuals.

A. Increased cobalamin levels. B. Decreased histamine levels. C. Increased hemoglobin levels. D. Increased red blood cell levels.

Correct Answer is ["C","D"]

Explanation

Choice A rationale:
Increased cobalamin levels are not indicative of polycythemia vera. Polycythemia vera is characterized by an increase in the total red blood cell mass. Elevated cobalamin levels are not specific to this condition.
Choice B rationale:
Decreased histamine levels are not a diagnostic marker for polycythemia vera. Histamine levels are not typically associated with this disorder.
Choice C rationale:
Increased hemoglobin levels are a significant finding in polycythemia vera. Polycythemia vera is a disorder characterized by an abnormal increase in the number of red blood cells, leading to elevated hemoglobin levels.
Choice D rationale:
Increased red blood cell levels are a hallmark feature of polycythemia vera. The increased production of red blood cells leads to elevated red blood cell levels, which is a key diagnostic indicator for this condition.
