Prognosis refers to the prediction of the outcome of a disease or medical condition. It involves forecasting the likely course, duration, and outcome of a patient's disease based on the condition's natural history, the patient's health, and the treatment options available. A prognosis can range from good, with full recovery expected, to poor, where complications or fatal outcomes are anticipated.

Question 19
The first sound heard when taking the blood pressure is:
Correct Answer: B
The first sound heard when taking the blood pressure is the systolic pressure, not diastolic. When measuring blood pressure with a sphygmomanometer, the first Korotkoff sound indicates the systolic pressure. It is the pressure in the arteries when the heart beats (contracts) and is the higher of the two blood pressure readings. Diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats, is indicated by the last Korotkoff sound heard.
