Nurse takes an adult patients blood pressure and determines it to be normal. What reading did the nurse obtain
Systolic pressure between 140 mmHg and 150 mmHg
Systolic pressure less than 120 mmHg and diastolic pressure less than 80 mmHg
Systolic pressure less than 100 mmHg regardless of diastolic pressure
Systolic pressure greater than 140 mmHg and a diastolic pressure of 100 mmHg
The Correct Answer is B
The correct answer is B. Systolic pressure less than 120 mmHg and diastolic pressure less than 80 mmHg is considered normal blood pressure in adults according to current guidelines. A systolic pressure between 140-150 mmHg (option A) would be classified as stage 1 hypertension, while a systolic pressure greater than 140 mmHg and diastolic pressure of 100 mmHg (option D) would be classified as stage 2 hypertension. A systolic pressure less than 100 mmHg regardless of diastolic pressure (option C) would be considered low blood pressure.

Correct Answer is B
Explanation
Varicose veins occur when the valves within the veins, which normally prevent the backflow of blood, become damaged or weakened, allowing blood to pool and the veins to become enlarged and twisted. This can occur due to a variety of factors, including age, pregnancy, obesity, genetics, and prolonged periods of standing or sitting. An increase in hydrostatic pressure can contribute to the development of varicose veins, but it is not the primary cause.
Correct Answer is C
Explanation
The left ventricle is responsible for pumping oxygenated blood out of the heart and into systemic circulation, which requires generating enough pressure to overcome the resistance of the systemic blood vessels. Therefore, the left ventricle has thicker and more muscular walls than the right ventricle and can generate higher pressures during contraction. In contrast, the right ventricle pumps deoxygenated blood to the lungs, which have lower resistance compared to the systemic circulation, and therefore do not need to generate as high pressures.
