FINAL [GUARANTEED PASS]
A 42-year-old presents with dyspnea, rapid shallow breathing, inspiratory crackles,
decreased lung compliance, and hypoxemia. Tests reveal a fulminant form of
respiratory failure characterized by acute lung inflammation and diffuse
alveolocapillary injury. What is the most likely diagnosis supported by the patient's
condition?
-Sarcoidosis
-Acute respiratory distress syndrome (ARDS)
-Malignant respiratory failure
-Postoperative respiratory failure - ANSWER-Acute respiratory distress
syndrome (ARDS)
Pneumonia is caused by?
-Chronic lung changes seen with aging
-Atelectasis
-Viral or bacterial infection
-Use of anesthetic agents in surgery - ANSWER-Viral or bacterial infection
The incidents of fractures of the pelvis is highest in?
-Adolescent boys
-Adolescent girls
-Older adults
,-Preadolescent boys - ANSWER-Older adults
A patient asks the nurse why they need to wear oxygen in the hospital and how it
works with blood cells. Which is the best response?
-Blood cells passing through the arteries in the lungs are oxygenated and then carry
oxygen to the body
-When you take in a breath the blood cells in your nose takes in the oxygen
-The blood that pumps through the heart takes in oxygen
-The blood receives oxygen from the bone marrow and carries it to the tissues -
ANSWER-Blood cells passing through the arteries in the lungs are oxygenated
and then carry oxygen to the body
How does severe hypoxia develop with pneumonia?
-Inflammatory exudate absorbs oxygen from the alveolar air
-Infection reduces effective compensation by the heart
-Acidosis depresses respirations
-Oxygen diffusion is impaired by the congestion - ANSWER-Oxygen diffusion
is impaired by the congestion

-89-92%
-97-100%
-90-93% - ANSWER-97-100%
, What causes the expanded anteroposterior (A-P) thoracic diameter (barrel chest) in
patients with emphysema?
-Persistent coughing to remove mucus
-Recurrent damage to lung tissues
-Dilated bronchi and increased mucus secretions
-Air trapping and hyperinflation - ANSWER-Air trapping and hyperinflation
What is an early sign of lung cancer?
-Weight loss
-Chronic cough
-Air trapping and over inflation of the lung
-Bone pain - ANSWER-Chronic cough
Which of the following describes lobar pneumonia?
-Sudden onset fever and chills with crackles and rusty sputum
-Insidious onset, diffuse interstitial infection
-Opportunistic bacteria causing low-grade fever with cough and thick greenish
sputum
-Viral infection causing nonproductive cough and pleuric pain - ANSWER-
Sudden onset fever and chills with crackles and rusty sputum
One of the functions of the pulmonary system is the?
-Principle mechanism for cooling the heart
-Exchange of gases between the environment and blood
