What is the independent variable in this experiment?

• Different classrooms

• Listening to classical music

• Taking a quiz

• How students do on the quiz

What are vital signs?

• Measurements of the body’s most basic functions and useful in detecting or monitoring medical problems.

• The rhythmic expansion and recoil of arteries resulting from heart contraction; can be felt from the outside of the body.

• A measure of cardiac activity usually expressed as the number of beats per minute.

• To recognize a disease by signs and symptoms.

What is Bacteria?

• Single-celled organisms that do not rely on a host.

• Tiny infectious agents that can only multiply when they are inside a host, the living cells of plants, animals or bacteria.

• Organisms such as yeasts or molds that reproduce quickly in a moist, humid environment.

• The time between contact and onset of illness.

What is Blood Pressure?

• The force of blood pushing against the walls of the arteries as the heart pumps blood and expressed in millimeters of mercury.

• The blood pressure generated by the heart during contraction.

• Blood pressure that remains between heart contractions.

• A measure of cardiac activity usually expressed as the number of beats per minute.

Vital signs are important for medical professionals because....

• They determine if a virus or infection may be in one's body.

• Gives medical professionals an idea of what might be wrong.

• Helps determine the treatment plan.

• All of the above

The four main vital signs are....?

• Body temperature, pulse rate, respiration rate and blood pressure.

• Body temperature, blood sugar, pulse rate, and blood pressure.

• Pulse rate, blood sugar, A1C, blood pressure.

• Respiration rate, blood sugar, blood pressure, pulse rate.

When taking blood pressure, systolic pressure refers to.....?

• The pressure inside the artery when the heart contracts and pumps blood through the body.

• The pressure inside the artery when the heart is at rest and filling with blood.

• The bottom number in a blood pressure reading.

• Written in Farenheit or Celsius degrees.

When taking blood pressure, the diastolic pressure refers to....?

• The pressure inside the artery when the heart is at rest and filling with blood.

• The pressure inside the artery when the heart contracts and pumps blood through the body.

• The top number in the blood pressure.
