Quiz 2

Angina pectoris

Occurs when myocardial oxygen demand exceeds the supply

Alveoli

The area of the lungs where respiration occurs

Sinoatrial (SA) node

The electrical impulse generated by the heart originates in the:

Correct statement regarding the hypoxic drive

The hypoxic drive stimulates a person to breathe on the basis of low oxygen levels.

acute myocardial infarction (AMI) occurs

when myocardial tissue dies secondary to an absence of oxygen

Correct statement of Anaphylaxis

Anaphylaxis is characterized by airway swelling and hypotension.

Most characteristic of adequate breathing

24 breaths/min with bilaterally equal breath sounds and pink skin

Provide reassurance and give oxygen as needed

A 22-year-old female patient is complaining of dyspnea and numbness and tingling in her hands and feet after an argument with her fiancé. Her respirations are 40 breaths/min. You should:

epinephrine

A 30-year-old male presents with acute shortness of breath, widespread hives, and facial swelling. He denies any past medical history and takes no medications. During your assessment, you hear wheezing over all lung fields. His blood pressure is 90/50 mm Hg and his heart rate is 110 beats/min. In addition to giving him 100% oxygen, the MOST important treatment for this patient is:

Placing patient in an upright position

A 67-year-old female presents with difficulty breathing and chest discomfort that awakened her from her sleep. She states that she has congestive heart failure, has had two previous heart attacks, and has prescribed nitroglycerin. She is conscious and alert with adequate breathing. Her blood pressure is 94/64 mm Hg and her heart rate is 120 beats/min. Treatment for this patient includes

dilating the affected coronary artery with a small inflatable balloon

A percutaneous transluminal coronary angioplasty (PTCA) restores blood flow to the ischemic myocardium by

Toxic chemical inhalation

Acute pulmonary edema would MOST likely develop as the result of this

Right atrium

Deoxygenated blood from the body returns to the

increased carbon dioxide levels

In a healthy individual, the brain stem stimulates breathing on the basis of:

Hypoglycemia

It Is not a major risk factor for AMI

Left atrium

Its function is to receive oxygenated blood from the lungs.

dilating the coronary arteries and improving cardiac blood flow

Nitroglycerin relieves cardiac-related chest pain by

Correct pulse oximetry statement

Pulse oximetry measures the percentage of hemoglobin that is saturated with oxygen, but does not measure the actual hemoglobin content of the blood.

Family history

Risk factors for AMI that cannot be controlled include

Denial

The most common reason that many people experiencing AMI do not seek immediate medical attention is

Inspiration and expiration

The two processes that occur during respiration

Acute coronary syndrome (ACS)

describes a group of symptoms that are caused by myocardial ischemia.

Reason why the left ventricle has the thickest walls

it pumps blood into the aorta and systemic circulation

Dyspnea

most accurately defined as shortness of breath or difficulty breathing.

The purpose of defibrillation

to stop the chaotic, disorganized contraction of the cardiac cells.
