Week 3 Flashcards
Your patient has just had an MRI ordered because a routine chest x-ray showed suspicious areas in the right lung. The physician suspects bronchogenic carcinoma.
You would know that an MRI would assess for what in this patient?
a. Patency of the bronchial tree
b. To evaluate inflammatory activity.
c. Ability to expand the lung
d. Chest wall invasion
e. Shunting of the blood supply
d. Chest wall invasion
You are caring for a patient with chronic obstructive pulmonary disease. When you auscultate this patient’s breath sounds, what do you expect to hear?
a. Continuous popping sounds early in inspiration.
b. Harsh, dry sounds originating in the large bronchi.
c. Discontinuous popping sounds heard in early inspiration.
d. Soft, high-pitched, popping sounds that occur during inspiration.
e. Snap crackle and pop just like Rice Bubbles.
c. Discontinuous popping sounds heard in early inspiration.
You are caring for a patient with a lower respiratory tract infection. You know that this type of infection causes what?
a. Impaired gas exchange.
b. Collapsed bronchial structures.
c. Ruptured blebs.
d. Closed bronchial tree.
e. Sputum production.
a. Impaired gas exchange.
You are working on a gerontology unit. You admit a 77-year-old with respiratory problems. You know that the amount of respiratory dead space increases with age. What do these changes result in?
a. Increased diffusion of gases.
b. Decreased diffusion capacity for oxygen.
c. Decreased shunting of blood.
d. Increased ventilation.
e. Increased perfusion.
B. Decreased diffusion capacity for oxygen.
Your patient has multiple sclerosis. Neuromuscular disorders such as multiple sclerosis may lead to a decreased vital capacity. What does vital capacity measure?
a. The volume of air inhaled and exhaled with each breath.
b. The volume of air in the lungs after a maximum inspiration.
c. The maximum volume of air inhaled after normal expiration.
d. The maximum volume of air exhaled from the point of maximum inspiration.
e. The maximum volume of air exhaled after a maximum expiration.
d. The maximum volume of air exhaled from the point of maximum inspiration.
The instructor of the physiology class for pre-nursing students is talking about the lower respiratory tract. The instructor talks about the visceral and parietal pleura and the small amount of fluid between the two membranes. What does the instructor tell her students the function of the pleura and the pleural fluid is?
a. Allows for full expansion of the lungs within the thoracic cavity.
b. Prevents the lungs from collapsing within the thoracic cavity.
c. Determines lung expansion within the thoracic cavity.
d. Permits smooth motion of the lungs within the thoracic cavity.
e. None of the above.
d. Permits smooth motion of the lungs within the thoracic cavity.
You are caring for a patient admitted with chronic obstructive pulmonary disease. During your shift assessment, you find that your patient is experiencing a change in his respiratory and mental status.
You are aware that the most accurate measurement of the concentration of oxygen in the patient’s blood is what?
a. A capillary blood sample.
b. Pulse oximetry.
c. An arterial blood gas study.
d. Assessment of the patient’s nailbeds.
e. Lung field auscultation
c. An arterial blood gas study.
You are the nurse working on the respiratory intensive care unit. You are aware that several respiratory conditions that can affect the compliance of the lung tissue. Which condition leads to an increase in lung compliance?
a. Emphysema
b. Pulmonary fibrosis
c. Pleural effusion
d. ARDS
e. Bronchitis
a. Emphysema
