From varying pressure areas to equal pressure areas

Which statement correctly describes the pressure relationship during expiration?

Pressure in alveoli is higher than in the atmosphere

Pressure in alveoli is lower than in the atmosphere

Pressure in alveoli is equal to the atmospheric pressure

There is no pressure difference between alveoli and the atmosphere

Which of the following is a consequence of hypercapnia?

Decreased rate and depth of respirations.

Increased oxygen levels in the blood.

What triggers the respiratory center during hypercapnia?

Increased carbon dioxide levels.

Decreased carbon dioxide levels.

How do chemoreceptors respond to hypoxemia?

They increase respiratory rate.

They decrease respiratory rate.

They respond by ignoring changes.

What is hypocapnia primarily caused by?

Low carbon dioxide concentration in the blood

High oxygen levels in the blood

High carbon dioxide concentration in the blood

What is the primary purpose of a Spirometry test?

To test pulmonary volumes and airflow times

What does Arterial blood gas determination check?

Oxygen, carbon dioxide, bicarbonate, serum pH

For whom is Exercise tolerance testing particularly indicated?

Patients with chronic pulmonary disease

Individuals with digestive issues

Young children for developmental assessment

What is the purpose of radiography in medical diagnostics?

To evaluate infections and tumors

What is determined by culture and sensitivity tests in medical diagnostics?

Which type of sputum is usually a sign of pneumococcal pneumonia?

Yellowish-green, cloudy, thick mucus

Very large amounts of purulent sputum

What are Kussmaul respirations characterized by?

Normal rate and depth of respirations

What is the characteristic pattern of Tachypnea in respiratory breathing?

Rapid superficial breathing; regular or irregular rhythm.

Slow respiratory rate; deeper than usual depth; regular rhythm.

Increased depth of respiration with a normal to increased rate and regular rhythm.

How is Cheyne-Stokes respiration identified?

Periodic breathing associated with periods of apnea, alternating regularly with a series of respiratory cycles; the respiratory cycle gradually increases, then decreases in rate and depth.

Long, gasping inspiratory phase followed by a short, inadequate expiratory phase.

Deep regular sighing respirations with an increase in respiratory rate.

Rhythm is smooth and even with expiration longer than inspiration.

What describes the respiratory pattern of Apneusis?

Long, gasping inspiratory phase followed by a short, inadequate expiratory phase.

Long, ineffective expiratory phase with shallow, increased respirations.

Periods of apnea alternating irregularly with a series of shallow breaths of equal depth.

Increased depth of respiration with a normal to increased rate and regular rhythm.

What does the term "Absence" in the context of breath sounds refer to?

Non-aeration or collapse of lungs

What is dyspnea often characterized by?

Retraction of muscles between or above ribs

Use of accessory respiratory muscles

Severe dyspnea indicative of respiratory distress can be noted by which symptom?

Often noted on exertion, such as climbing stairs

Usually caused by pulmonary congestion
