NU226 CH 39 Oxygenation and perfusion

The nurse educator is presenting a lecture on the respiratory and cardiovascular systems. Which response given by the nursing staff would indicate to the educator that they have an understanding of cardiac output?

"If the client's stroke volume is 50 mL and heart rate is 50 beats per minute, then the cardiac output is 2.5 L/minute."

The nurse is administering oxygen to an older adult client who has been assessed to have increased work of breathing. If the intervention has been effective, what finding(s) will the nurse expect on the evaluation of the client? Select all that apply.

-Heart rate is 64 beats/min. -Mucous membranes are pink and moist. -The client is able to state the date, time, and location.

The nurse is caring for a client who has a compromised cardiopulmonary system and needs to assess the client's tissue oxygenation. The nurse would use which appropriate method to assess this client's oxygenation?

ABG

A client is admitted to the hospital with shortness of breath, cyanosis and an oxygen saturation of 82% (0.82) on room air. Which action should the nurse implement first?

Apply oxygen as prescribed

A nurse is reading a journal article about pollutants and their effect on an individual's respiratory function. Which problem would the nurse most likely identify as an effect of exposure to automobile pollutants?

Bronchitis

Upon evaluation of a client's medical history, the nurse recognizes that which condition may lead to an inadequate supply of oxygen to the tissues of the body?

Chronic anemia

Which medication is administered in the home or the hospital to relieve inflammation in the lung tissue?

Corticosteroids

Oxygen and carbon dioxide move between the alveoli and the blood by:

Diffusion

The nurse is implementing an order for oxygen for a client with facial burns. Which delivery device will the nurse gather?

Face tent

A client has been put on oxygen therapy because of low oxygen saturation levels in the blood. What should the nurse use to regulate the amount of oxygen delivered to the client?

Flow meter

An older adult client is visibly pale with a respiratory rate of 30 breaths per minute. Upon questioning, the client states to the nurse, "I can't seem to catch my breath." The nurse has responded by repositioning the client and measuring the client's oxygen saturation using pulse oximetry, yielding a reading of 90%. The nurse should interpret this oxygen saturation reading in light of the client's:

Hemoglobin level

Which teaching about the humidifier is important for the nurse to provide to a client using oxygen?

It decreases dry mucous membranes via delivering small water droplets.

Which teaching about the oxygen analyzer is important for the nurse to provide to a client using oxygen?

It determines whether the client is getting enough oxygen.

The nurse is suctioning a client's tracheostomy when the tracheostomy becomes dislodged and the nurse is unable to replace it easily. What is the nurse's most appropriate response?

Maintain the client's oxygenation and alert the health care provider immediately.

While examining a client, the nurse palpates the client's chest and back. What would the nurse expect to identify with this technique?

Pattern of thoracic expansion

Which diagnostic procedure measures lung size and airway patency, producing graphic representations of lung volumes and flows?

Pulmonary function test

When reviewing data collection on a client with a cardiac output of 2.5 liter/minute, the nurse inspects the client for which symptom?

Rapid respirations

To drain the apical sections of the upper lobes of the lungs, the nurse should place the client in which position?

high-Fowler's position

While auscultating a client's chest, the nurse auscultates crackles in the lower lung bases. What condition does the nurse identify the client is experiencing?

presence of fluid in the lungs

A nurse suctioning a client through a tracheostomy tube should be careful not to occlude the Y-port when inserting the suction catheter because it would cause what condition to occur?

trauma to the tracheal mucosa
