Vital Signs and Patient Monitoring Flashcards

Korotkoff sounds heard during blood pressure measurement represent:

Answer: Blood flow through a partially compressed artery

Korotkoff sounds are produced by turbulent blood flow as the cuff pressure releases over the artery.

The first Korotkoff sound corresponds to which measurement?

Answer: Systolic pressure

The first audible tapping sound marks the systolic pressure.

Which patient position is preferred for routine vital sign measurement?

Answer: Seated with feet flat on the floor

A seated position with feet flat and back supported gives the most reliable routine readings.

Orthostatic vital signs are taken to evaluate:

Answer: Blood pressure changes with position

Orthostatic measurements compare blood pressure and pulse lying, sitting, and standing to detect positional drops.

A weak, thready pulse is most often associated with:

Answer: Decreased circulating blood volume

A thready pulse typically reflects reduced blood volume or poor cardiac output.

Which thermometer site is generally avoided in infants for safety reasons?

Answer: Oral

Oral temperatures are unreliable and unsafe in infants who cannot hold the thermometer properly.

Pulse pressure is calculated by:

Answer: Subtracting diastolic from systolic

Pulse pressure is the difference between systolic and diastolic readings.
