A client is being treated for a pulmonary embolism and the medical nurse is aware that the client suffered an acute disturbance in pulmonary perfusion. This involved an alteration in what aspect of normal physiology?

Adequate flow of blood through the pulmonary circulation.

What does adequate gas exchange depend on?

An adequate ventilation-perfusion ratio.

The client admitted with a deep vein thrombosis (DVT) is now complaining of chest pain and dyspnea. Which is the primary intervention for the nurse to take?

A 26-year-old woman is thankful to be alive after rear-ending a truck with her car. However, she experienced a sternal fracture from the force of her car's airbag and has been breathing shallowly to avoid exacerbating her pain. The nurse should consequently prioritize assessments related to:

Atelectasis

The health care provider has ordered continuous positive airway pressure (CPAP) with the delivery of oxygenation. The patient asks the nurse what the benefit of CPAP is. What would be the nurse's best response?

CPAP prevents the collapse of the patient's airway

When giving oxygen to a hypoxic patient, the nurse must remember that oxygen transport is also dependent on the arterial oxygen content. Which of the following is a blood gas analysis that would indicate the presence of hypoxemia?

PaO2 < 60 mm Hg

A client is brought to the emergency department following a motor vehicle accident. Which of the following nursing assessments is significant in diagnosing this client with flail chest?

Paradoxical chest movement

A patient exhibited signs of an altered ventilation-perfusion ratio. The nurse is aware that adequate ventilation but impaired perfusion exists when the patient has which of the following conditions?

Pulmonary embolism

Patient's arterial blood gas analysis reveals a pH of 7.32 and a PCO2 of 60. Which of the following imbalances do these values reveal?

Respiratory acidosis

The nurse initiates the following intervention upon receiving a client back to the clinical unit after a throat-related procedure, "Elevate the head of the bed 45°." This assists in meeting which nursing goal?

The client will have decreased edema.

Ventilation exceeds perfusion.

A client is at risk for respiratory alkalosis. In an attempt to restore the acid-base balance, the client's:

kidneys will excrete more HCO3 to lower the pH.

The nurse is interpreting blood gases for a client with acute respiratory distress syndrome (ARDS). Which set of blood gas values indicates respiratory acidosis?

pH 7.25, PaCO2 48, HCO3 24
