Correct Answer is B

Explanation

A. While controlling carbohydrate intake may be beneficial for managing blood glucose levels in some cases, it is not a primary dietary concern for chronic kidney disease.
B. Patients with chronic kidney disease often need to limit potassium intake because the kidneys may have difficulty excreting excess potassium, leading to hyperkalemia.
C. While protein restriction may be necessary in advanced stages of chronic kidney disease to reduce the workload on the kidneys, complete elimination of protein is not recommended.
D. Sodium restriction is often recommended for patients with chronic kidney disease to help control blood pressure and fluid balance.

A. Atrial depolarization B. Atrial repolarization C. Ventricular depolarization D. Ventricular repolarization

Correct Answer is A

Explanation

A. The P wave on an ECG represents atrial depolarization, which occurs as the electrical impulse originates in the sinoatrial (SA) node and spreads through the atria, initiating atrial contraction.
B. Atrial repolarization typically occurs during the QRS complex and is not represented by the P wave. Atrial repolarization is masked by the larger QRS complex.
C. Ventricular depolarization is represented by the QRS complex on an ECG, as the electrical impulse spreads through the ventricles, leading to ventricular contraction.
D. Ventricular repolarization typically occurs during the T wave and is not represented by the P wave. Ventricular repolarization involves the recovery of ventricular muscle cells after contraction.
