Which acid-base mechanism would the kidney use to buffer a patient's acidosis (serum pH <7.35)? Select all that apply.
One, some, or all responses may be correct.

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.

Choice A rationale:

Taking a daily walk is a beneficial activity for patients with venous leg ulcers. Walking promotes blood circulation, which can aid in wound healing. This statement indicates that the patient understands the importance of physical activity for their condition.

Choice B rationale:

Trying to lose weight is another positive step for a patient with venous leg ulcers, especially if the patient is overweight. Excess body weight can put additional pressure on the veins in the legs, worsening venous insufficiency. Losing weight can alleviate this pressure and improve venous circulation, supporting the healing process of leg ulcers.

Choice C rationale:

Wearing stockings after getting out of bed is a proper technique for managing venous leg ulcers. Compression stockings help improve blood flow in the legs and reduce swelling, which is beneficial for patients with venous insufficiency and leg ulcers. This statement indicates that the patient understands the importance of wearing compression stockings consistently.

Choice D rationale:

Not wearing knee-high socks that are tight around the calf is essential advice for patients with venous leg ulcers. Tight clothing, including socks or stockings, can impede blood circulation in the legs, worsening venous insufficiency and delaying wound healing. This statement indicates the need for further education because the patient should avoid any tight clothing around the affected area to promote optimal blood flow and wound healing.
