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.
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 ["A","D"]
Explanation
Choice A rationale:
Eliminating excess H+ ions (hydrogen ions) is a primary mechanism the kidneys use to buffer acidosis. In acidosis, there is an excess of hydrogen ions in the body, leading to a decrease in pH. The kidneys help regulate the body's pH by excreting hydrogen ions to lower acidity.
Choice B rationale:
Excreting excess water is not a specific acid-base mechanism related to acidosis. While maintaining proper hydration is important for overall health, it does not directly influence the body's acid-base balance in the context of acidosis.
Choice C rationale:
Eliminating excess CO2 is primarily a respiratory mechanism, not a kidney function. CO2 elimination is more related to the lungs' ability to regulate the body's pH by adjusting respiratory rate and depth.
Choice D rationale:
Reabsorbing additional HCO3- ions (bicarbonate ions) is a renal mechanism to buffer acidosis. Bicarbonate ions act as a base and can neutralize excess hydrogen ions, raising the pH of the body fluids.
Choice E rationale:
Reabsorbing additional sodium ions is not a specific acid-base mechanism related to acidosis. While sodium ions are important for various physiological processes, they do not play a direct role in buffering acidosis.
Correct Answer is C
Explanation
The correct answer is choice C. Uses an alcohol-based mouthwash twice a day.
Choice A rationale:
Drinking 14 glasses of water daily is generally beneficial as it helps maintain hydration and supports overall health. However, it is important to balance fluid intake to avoid overhydration.
Choice B rationale:
Shaving with an electric razor is recommended for patients with thrombocytopenia because it reduces the risk of cuts and bleeding compared to using a traditional razor.
Choice C rationale:
Using an alcohol-based mouthwash can cause dryness and irritation of the oral mucosa, which can lead to bleeding, especially in patients with thrombocytopenia. It is better to use a non-alcoholic mouthwash.
Choice D rationale:
Brushing teeth with a soft-bristle toothbrush is advised to minimize the risk of gum bleeding and maintain oral hygiene.
