ARDS Nclex Exam Questions and

Answers 100% Solved


1. It will be most important for the nurse to check pulse oximetry for which

of these patients?

a. A patient with emphysema and a respiratory rate of 16

b. A patient with massive obesity who is refusing to get out of bed

c. A patient with pneumonia who has just been admitted to the unit

d. A patient who has just received morphine sulfate for postoperative pain -

✔✔C

Rationale: Hypoxemia and hypoxemic respiratory failure are caused by

disorders that interfere with the transfer of oxygen into the blood, such as

pneumonia. The other listed disorders are more likely to cause problems

with hypercapnia because of ventilatory failure.

2. The nurse will monitor for clinical manifestations of hypercapnia when a

patient in the emergency department has

a. chest trauma and multiple rib fractures.

b. carbon monoxide poisoning after a house fire.

c. left-sided ventricular failure and acute pulmonary edema.

d. tachypnea and acute respiratory distress syndrome (ARDS). - ✔✔A

Rationale: Hypercapnia is caused by poor ventilatory effort, which occurs in

chest trauma when rib fractures (or flail chest) decrease lung ventilation.

Carbon monoxide poisoning, acute pulmonary edema, and ARDS are more

commonly associated with hypoxemia.

3. When a patient is diagnosed with pulmonary fibrosis, the nurse will teach

the patient about the risk for poor oxygenation because of

a. too-rapid movement of blood flow through the pulmonary blood vessels.

b. incomplete filling of the alveoli with air because of reduced respiratory

ability.

c. decreased transfer of oxygen into the blood because of thickening of the

alveoli.

d. mismatch between lung ventilation and blood flow through the blood

vessels of the lung. - ✔✔C

Rationale: Pulmonary fibrosis causes the alveolar-capillary interface to

become thicker, which increases the amount of time it takes for gas to

diffuse across the membrane. Too-rapid pulmonary blood flow is another

cause of shunt but does not describe the pathology of pulmonary fibrosis.

Decrease in alveolar ventilation will cause hypercapnia. Ventilation and

perfusion are matched in pulmonary fibrosis; the problem is with diffusion.

4. A patient is diagnosed with a large pulmonary embolism. When

explaining to the patient what has happened to cause respiratory failure,

which information will the nurse include?

a. "Oxygen transfer into your blood is slow because of thick membranes

between the small air sacs and the lung circulation."
