EMT 1

The extremity lift would NOT be appropriate to use on a patient:

With a deformed humerus.

Supplemental oxygen without assisted ventilation would MOST likely be administered to patients:

With difficulty breathing and adequate tidal volume.

A patient with spontaneous respirations is breathing:

Without assistance.

An infant or small child's airway can be occluded if it is overextended or overflexed because:

the occiput is proportionately large and the trachea is flexible.

Negative-pressure breathing involves

A drop in pressure within the chest cavity.

Erythrocytes

A hormone that is released by the adrenal medulla and by the sympathetic nerves and functions as a neurotransmitter. It is also used as a drug to raise blood pressure.

Norepinephrine.

A hormone that is released by the adrenal medulla and by the sympathetic nerves and functions as a neurotransmitter. It is also used as a drug to raise blood pressure.

Epinephrine

Adrenaline

___________ pressure is the pressure exerted by a liquid that occurs when blood moves through an artery at relatively high pressures.

Hydrostatic

Breathing occurs as the result of a(n):

Increase in carbon dioxide, which decreases the pH of the cerebrospinal fluid.

Not an that contribute to a decline in the vital capacity of an elderly patient include all of the following,

Increased surface area available for air exchange.

The diastolic blood pressure represents the:

Minimum amount of pressure that is always present in the arteries.

According to Occupational Safety and Health Administration (OSHA) regulations, an employer must:

Offer a workplace environment that reduces the risk of exposure.

A scenario that MOST accurately depicts abandonment?

A paramedic transfers patient care to an EMT.

A 15-year-old boy was killed when he was struck by a car while riding his bicycle. He has numerous disfiguring injuries and has been placed in the back of the ambulance to shield him from curious bystanders. When the child's parents arrive at the scene, they demand to see him. You should:

Advise them that their son had severely disfiguring injuries and ask them if there is anyone they would like you to contact first.

Palpation

An examination technique in which the examiner's hands are used to feel the texture, size, consistency, and location of certain body parts

A correct statements regarding an infant's vital signs?

An infant's normal body temperature is typically higher than a preschooler's

Both areas of the pons are used to:

Augment respirations during emotional or physical stress.

Mean arterial pressure (MAP) is a product of:

Cardiac output and systemic vascular resistance.

A patient's short-term memory is MOST likely intact if he or she correctly answers questions regarding:

Date and event.

Which of the following MOST accurately defines negligence?

Deviation from the standard of care that may result in further injury

This is not a common factors that influence how a patient reacts to the stress of an illness or injury:

Distrust of EMTs.

Key hormones of the sympathetic nervous system include:

Epinephrine and norepinephrine.

Hemoglobin is a molecule that attaches to ___________ and carries oxygen.

Erythrocytes

A blood pressure cuff that is too small for a patient's arm will give a:

Falsely high systolic and diastolic reading.

A 71-year-old female slipped on a rug and fell. She is conscious and alert and complains of severe pelvic pain. Her respirations are 22 breaths/min with adequate depth and her heart rate is 120 beats/min. Which of the following is NOT indicated for this patient?

Gentle palpation of the pelvis

If you cannot palpate a pulse in an unresponsive patient whose collapse was not witnessed, you should:

Immediately begin CPR.

In late adults, the amount of air left in the lungs after expiration of the maximum amount of air:

Increases, which hampers diffusion of gases because of the stagnant air that remains in the alveoli.

A 40-year-old male presents with pain to the right upper quadrant of his abdomen. He is conscious and alert with stable vital signs. During your assessment, you note that his skin and sclera are jaundiced. You should suspect:

Liver dysfunction.

Which of the following are noticeable characteristics of a 9-month-old infant?

Places objects in the mouth, pulls himself or herself up

A 50-year-old male presents with altered mental status. His wife tells you that he had a "small stroke" three years ago but has otherwise been in good health. The patient is responsive but unable to follow commands. After administering oxygen if needed, you should:

Prepare for immediate transport.

In responsive patients who are older than 1 year of age, you should palpate the pulse at the ________ artery.

Radial

You and your partner enter the residence of an elderly couple, both of whom are found unconscious in their bed. There is no evidence of trauma. As you begin your assessment, you and your partner notice the smell of natural gas in the residence. Which of the following should be your MOST appropriate action?

Rapidly remove the patients from their residence using a blanket or clothes drag.

Systemic vascular resistance.

Resistance to blood flow out of the left ventricle created by the systemic circulatory system

Activities such as walking, talking, and writing are regulated by the:

Somatic nervous system.

A crackling sound produced by air bubbles under the skin is called:

Subcutaneous emphysema

After performing a head tilt-chin lift maneuver to open the airway of an unresponsive patient who has a pulse, you should:

Suction as needed and insert an airway adjunct.

Cardiac output

The amount of blood the heart pumps through the circulatory system in a minute Calculated by bpm x stroke volume

Somatic nervous system.

The part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles

Stroke volume

The volume of blood pumped from a ventricle of the heart in one beat
