the nurse explains to the hypertensive client that the increased workload required to pump blood against an elevated arterial pressure results in a progressive increase in left ventricular muscle mass. this is an example of:

dysplasia.

metaplasia.

hyperplasia.

hypertrophy.

Explanation:

Hypertrophy is an increase in cell size. In hypertension, the left ventricle works harder against elevated arterial pressure. This leads to an increase in left ventricular muscle mass (cell size), which is hypertrophy. Dysplasia is abnormal cell growth and arrangement. Metaplasia is the replacement of one cell type with another. Hyperplasia is an increase in cell number. So, the described situation is hypertrophy.

Answer:

hypertrophy.
