Final answer:
Dr. Ally's problems stem from poor management of his essential hypertension, leading to high blood pressure and signs of cardiovascular complications.
Step-by-step explanation:
Dr. Ally, diagnosed with essential hypertension 12 years ago, is experiencing complications from not adhering to prescribed antihypertensive medication. Hypertension is a condition with chronically elevated blood pressure, often symptomless and known as the "silent killer" because it can lead to serious health issues, such as heart attacks, strokes, chronic kidney disease, or heart failure, if left untreated. Dr. Ally's symptoms including tiredness, dyspnea, epistaxis, dizziness, and blurred vision indicate that his hypertension is poorly controlled, contributing to his high blood pressure reading of 180/110 and potential cardiovascular complications, as evidenced by the presence of rales upon chest auscultation.
