Chapter 38 O2

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?

Arterial blood gas

The nurse is educating an adolescent with asthma on how to use a metered-dose inhaler. Which education point follows recommended guidelines?

Be sure to shake the canister before using it.

Upon auscultation of the client's lungs, the nurse hears loud, high-pitched sounds over the larynx. What term will the nurse use in documentation to describe this breath sound?

Bronchial

A nurse measuring the arterial oxyhemoglobin saturation (SaO2 or SpO2) of a client's arterial blood gets a weak signal from the pulse oximeter. What would be the appropriate intervention in this situation?

Check vital signs and client condition.

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

Corticosteroids

Which dietary guideline would be appropriate for the older adult homebound client with advanced respiratory disease who informs the nurse that she has no energy to eat?

Eat smaller meals that are high in protein.

A nurse is caring for a client who breathes very shallowly and has been reporting severe back pain. What suggestion could the nurse make to help the client breathe efficiently?

Encourage the client to take deep breaths.

The nurse assesses a client and detects the following findings: difficulty breathing, increased respiratory and pulse rates, and pale skin with regions of cyanosis. What condition would the nurse suspect as causing these respiratory alterations?

Hypoxia

To determine the quality of oxygenation, the nurse performs the physical assessment, the arterial blood gas test, and pulse oximetry. What is the purpose of the pulse oximetry test?

Monitor the amount of oxygen saturation in the blood.

Which is a sign of dyspnea specific to infants?

Nasal flaring

Which is a major organ of the upper respiratory tract?

Pharynx

A patient's primary care provider has informed the nurse that the patient will require thoracentesis. The nurse should suspect that the patient has developed which of the following disorders of lung function?

Pleural effusion

While auscultating a client's chest, a nurse hears coarse crackles that are soft, high-pitched and discontinuous. The nurse interprets this finding as indicating which of the following?

Presence of sputum in the airways

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

Pulmonary function tests

A client returns to the telemetry unit after an operative procedure. Which diagnostic test will the nurse perform to monitor the effectiveness of the oxygen therapy ordered for the client?

Pulse oximetry

The nurse is caring for a postoperative client who has a prescription for meperidine (Demerol) 7 5mg intramuscularly (IM) every 4 hours as needed for pain. Before and after administering Demerol, the nurse would assess which most important sign?

Respiratory rate and depth

The nurse is auscultating the lungs of a client and detects normal vesicular breath sounds. What is a characteristic of vesicular breath sounds?

They are low-pitched, soft sounds heard over peripheral lung fields.

After insertion of a chest tube, fluctuations in the water-seal chamber that correspond with inspiration and expiration are an expected and normal finding.

True

The nurse sets up an oxygen tent for a client. Which client is the best candidate for this oxygen delivery system?

a child who has pneumonia

In which client would the nurse assess for a depressed respiratory system?

a client taking opioids for cancer pain

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

diffusion

A client with no prior history of respiratory illness has been admitted to a postoperative unit following foot surgery. What intervention should the nurse prioritize in an effort to prevent postoperative pneumonia and atelectasis during this time of reduced mobility following surgery?

educating the client on the use of incentive spirometry

The nurse is conducting a respiratory assessment of a client age 71 years who has been recently admitted to the hospital unit. Which assessment finding should the nurse interpret as abnormal?

fine crackles to the bases of the lungs bilaterally

The nurse is caring for a client who is diagnosed with impaired gas exchange. While performing a physical assessment of the client, which data is the nurse likely to find, keeping in mind the client's diagnosis?

high respiratory rate

A patient with a diagnosis of advanced Alzheimer disease who is unable to follow directions requires an inhaled bronchodilator. Which of the following medication delivery systems is most appropriate for this patient?

nebulizer

What is the action of codeine when used to treat a cough?

suppressant

Which actions would a nurse perform when correctly providing postural drainage? Select all that apply.

• Place the client in a high- Fowler's position to drain the apical sections of the upper lobes of the lungs. • Carry out postural drainage 2 to 4 times a day for 20 to 30 minutes. • Place the client in a lying position, half on the abdomen and half on the side, right and left, to drain the posterior sections of the upper lobes of the lungs.

Which actions should a nurse perform when inserting an oropharyngeal airway? Select all that apply.

• Wash hands and put on PPE, as indicated. • Rotate the airway 180 degrees as it passes the uvula. • Remove airway for a brief period every 4 hours or according to facility policy.
