Correct Answer is A

Explanation

A. Atrial fibrillation (AF) is more common in older adults, particularly those with underlying conditions like chronic obstructive pulmonary disease (COPD). COPD can lead to structural changes in the heart, increasing the risk of AF. The elderly are particularly vulnerable due to age-related heart changes and comorbidities such as lung disease.

B. While carotid endarterectomy is a surgical procedure that can be related to stroke prevention, it is not directly associated with a higher risk of AF compared to COPD.

C. Aspirin is used for its antiplatelet effects, not directly related to the risk of AF.

D. Post coronary artery bypass graft (CABG) surgery increases the risk for arrhythmias, but it is less directly linked to AF than conditions like COPD in an older adult.

A. Neurologic status B. Urine volume C. Cardiac rhythm D. Calcium level

Correct Answer is C

Explanation

A. Neurologic status is important to monitor but is not directly related to evaluating calcium gluconate's effect on hyperkalemia.

B. Urine volume would not directly reflect the immediate effects of calcium gluconate in managing hyperkalemia.

C. Calcium gluconate is given to protect the heart from the effects of hyperkalemia by stabilizing the cardiac membrane. Monitoring the cardiac rhythm is essential to assess the effectiveness of the treatment.

D. The calcium level is relevant for monitoring the calcium treatment, but cardiac rhythm is a more immediate indicator of its effectiveness.
