1

The primary purpose of the respiratory system is gas exchange. This involves?

transfer of O2 and CO2 between the atmosphere and blood. The respiratory system is divided into two parts: upper respiratory tract and lower respiratory tract

2

The upper respiratory tract includes the?

nose, mouth, pharynx, epiglottis, larynx, and trachea

3

Once air passes the carina, it is in the lower respiratory tract. The lower respiratory tract consists of the?

bronchi, bronchioles, alveolar ducts, and alveoli.
-lung lobes

4

A patient with metabolic alkalosis has an SpO2 of 93% and a shift to the left in the oxygen-hemoglobin dissociation curve. Which action by the nurse is appropriate?
-Administer supplemental oxygen because less oxygen is dissolved in the blood.
-Discontinue supplemental oxygen because more oxygen is released to the tissues.
-Administer supplemental oxygen because oxygen is not readily released to the tissues.
-Discontinue supplemental oxygen because more oxygen is dissolved in the blood.

Administer supplemental oxygen because oxygen is not readily released to the tissues.

5

A patient’s arterial blood gas (ABG) results include the following: pH 7.32, PaO2 84 mm Hg, PaCO2 49 mm Hg, and SaO2 84%. For what should the nurse assess the patient?
Tetany
Tachypnea
Pleural friction rub
Kussmaul respirations

Tachypnea

6

The nurse would interpret an induration of 5 mm resulting from tuberculin skin testing as a positive finding in which patient?

A patient with a history of illegal IV drug use
A patient with diabetes and end-stage kidney disease
A patient who immigrated from India 3 months ago
A patient who is human immunodeficiency virus- infected

A patient who is human immunodeficiency virus- infected

Gerontologic Considerations:Effects of Aging on Respiratory System
1) Structural changes
Chest wall stiffening
Costal cartilage calcification
↑ Anteroposterior diameter
↓ Elastic recoil
↓ Chest wall compliance
↓ Functioning alveoli
↓ Respiratory muscle strength
2) Defense mechanisms
↓ Cell-mediated immunity
↓ Specific antibodies
↓ Cilia function
↓ Cough force
↓ Alveolar macrophage function
↓ Sensation in pharynx
3) Respiratory control
↓ Response to hypoxemia
↓ Response to hypercapnia
