Q

A patient’s systolic pressure is 160 mmHg, and their diastolic pressure is 100 mmHg. Is this patient in hypertensive crisis?

A

Yes, this meets the criteria for hypertensive crisis (>180/120 mmHg), and immediate medical attention is needed.

Q

A patient has a blood pressure of 130/85 mmHg. If their heart rate is 80 bpm, what is their pulse pressure, and what does it indicate about their cardiovascular health?

A

Pulse pressure: 130 - 85 = 45 mmHg

Interpretation: A normal pulse pressure indicates good arterial elasticity.

Q

Explain how narrowing of blood vessels (vasoconstriction) affects systolic and diastolic pressures.

A

Vasoconstriction increases resistance in blood vessels, leading to higher systolic and diastolic pressures.
