Foundations Vital Signs

Where is the primary site for heat loss?

• head

• skin

• lungs

• kidneys

What is the difference between the amount of heat produced by the body and the amount of heat loss to the environment? (pg 646)

• Conduction

• Metabolism

• Temperature

• Convection

The primary source of heat in the body is metabolism. Shivering is a response that increases the production of heat. Where is this initiated? (page 646)

• Pons

• Muscle movement

• Medulla oblangata

• Hypothalamus

The nurse is caring for a patient that has been diaphoretic. They have transferred heat by which mechanism? (page 647)

• Conduction

• Evaporation

• Radiation

• Convection

What regulates the pulse? (page 653)

• Sinoatrial (SA) node

• Medulla Oblongata

• Hypothalamus

• Atrioventricular (AV) node

Which statements are true of the physiology of the pulse? (select all that apply) (page 653)

• Women have a lower pulse than men

• Pulse rate decreases with age

• Pulse decreases with exercise

• Pyrexia increases the pulse

• When blood volume decreases the pulse increases

What helps maintain blood pressure? (page 659)
