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 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.
Correct Answer is C
Explanation
Choice A rationale:
While magnesium is indeed the most abundant intracellular cation in the body, this fact alone does not explain why the nurse would assess the patient's magnesium level.
Choice B rationale:
Magnesium imbalance can cause issues in the extracellular fluid compartment, but this choice does not explain why the nurse would specifically assess the patient's magnesium level.
Choice D rationale:
While hypotension can be a symptom of severe magnesium deficiency, this choice does not provide a rationale for assessing the patient's magnesium level. In this case, choice C is correct because magnesium plays a crucial role in neuromuscular excitability and contractility. Abnormal magnesium levels can lead to neuromuscular symptoms such as muscle weakness, tremors, and spasms. Additionally, magnesium is involved in cardiac muscle function, and low magnesium levels can lead to arrhythmias and other cardiac issues. Therefore, assessing the patient's magnesium level is essential in understanding their neuromuscular and cardiac health.
