Respiratory Disorders

Emphysema is described by which of the following statements?

A disease of the airways characterized by destruction of the walls of overdistended alveoli

A 55-year-old client is scheduled for spirometry testing for evaluation of chronic obstructive pulmonary disease (COPD). The nurse

Asks the client, "What are your allergies?" Explanation: Spirometry testing includes use of a bronchodilator and then further testing. The nurse needs to assess for allergies first. The client does not need to be NPO prior to spirometry testing. Venous blood work may be done for clients younger than 45 years old, to check for a deficiency in alpha 1-antitrypsin. Arterial blood gases, if ordered, are obtained prior to spirometry testing.

Asthma is cause by which type of response?

IgE-mediated

A client is admitted to a health care facility for treatment of chronic obstructive pulmonary disease. Which nursing diagnosis is most important for this client?

Impaired gas exchange related to airflow obstruction

Which of the following is a characteristics of emphysema?

Increased total lung capacity

A nurse is assisting with a subclavian vein central line insertion when the client's oxygen saturation drops rapidly. He complains of shortness of breath and becomes tachypneic. The nurse suspects the client has developed a pneumothorax. Further assessment findings supporting the presence of a pneumothorax include:

diminished or absent breath sounds on the affected side

Which of the following is accurate regarding status asthmaticus?

A severe asthma episode that is refractory to initial therapy

A physician orders a beta2 adrenergic-agonist agent (bronchodilator) that is short-acting and administered only by inhaler. The nurse knows this would probably be

Albuterol Short-acting beta2-adrenergic agonists include albuterol, levalbuterol, and pirbuterol. They are the medications of choice for relief of acute symptoms and prevention of exercise-induced asthma. They are used to relax smooth muscle.

Which of the following occupy space in the thorax, but do not contribute to ventilation?

Bullae Explanation: Bullae are enlarged airspaces that do not contribute to ventilation but occupy space in the thorax. Bullae may compress areas of healthier lung and impair gas exchange.

A client with chronic obstructive pulmonary disease (COPD) reports increased shortness of breath and fatigue for 1 hour after awakening in the morning. Which of the following statements by the nurse would best help with the client's shortness of breath and fatigue?

Delay self-care activities for one hour Explanation: Some clients with COPD have shortness of breath and fatigue in the morning on arising as a result of bronchial secretions. Planning self-care activities around this time may be better tolerated by the client, such as delaying activities until the client is less short of breath or fatigued. The client raising the arms over the head may increase dyspnea and fatigue. Sitting in a chair when bathing or dressing will aid in dyspnea and fatigue but does not address the situation upon arising. Drinking fluids will assist in liquifying secretions which, thus, will aid in breathing, but again does not address the situation in the morning.

The nurse has instructed the client to use a peak flow meter. The nurse evaluates client learning as satisfactory when the client

Exhales hard and fast with a single blow Explanation: To use a peak flow meter, the client stands. Then the client takes a deep breath and exhales hard and fast with a single blow. The client repeats this twice and records a "personal best" in an asthma diary.

A client with chronic obstructive pulmonary disease (COPD) expresses a desire to quit smoking. The first appropriate response from the nurse is:

Have you tried quitting before?

In chronic obstructive pulmonary disease (COPD), decreased carbon dioxide elimination results in increased carbon dioxide tension in arterial blood, leading to which of the following acid-base imbalances?

Increased carbon dioxide tension in arterial blood leads to respiratory acidosis and chronic respiratory failure. In acute illness, worsening hypercapnia can lead to acute respiratory failure. The other acid-base imbalances would not correlate with COPD.

Which of the following is the key underlying feature of asthma?

Inflammation

A client has intermittent asthma attacks. Which of the following therapies does the nurse teach the client to use at home when experiencing an asthma attack?

Inhaled albuterol (Ventolin)

mild COPD

The classification of Stage I of COPD is defined as

The hormone brain natriuretic peptide (BNP) is produced by which of the following?

Ventricles of the heart

A nurse is caring for a client admitted with an exacerbation of asthma. The nurse knows the client's condition is worsening when he:

uses the sternocleidomastoid muscles.

Nursing students are gathered for a study session about the pulmonary system. One student asks the others to name the primary causes for an acute exacerbation of COPD. Which of the following responses should be in the reply? Choose all that apply.

• Air pollution • Tracheobronchial infection Explanation: Common causes of an acute exacerbation include tracheobronchial infection and air pollution. However, the cause of approximately one third of severe exacerbations cannot be identified. Fractured hips, hypertension, and GI viruses are not causes of exacerbation of COPD.

A client with asthma has developed obstruction of the airway. Which of the following does the nurse understand as having potentially contributed to this problem? Choose all that apply.

• Thick mucus • Swelling of bronchial membranes • Airway remodeling

Which of the following are risk factors for the development of chronic obstructive pulmonary disease (COPD)? Select all that apply.

• Tobacco smoke • Occupational dust • Air pollution • Infection • Second-hand smoke

Which of the following medications are classified as leukotriene modifiers (inhibitors)? Select all that apply.

• Zafirlukast (Accolate) • Montelukast (Singulair) • Zileuton (Zyflo) Explanation: Singulair, Accolate, and Zyflo are leukotriene modifiers. Atrovent is a short-acting anticholinergic. Spiriva is a long-acting anticholinergic.

A nurse is caring for a client with status asthmaticus. Which medication should the nurse prepare to administer?

An inhaled beta2-adrenergic agonist Explanation: An inhaled beta2-adrenergic agonist helps promote bronchodilation, which improves oxygenation. Although an I.V. beta2-adrenergic agonist can be used, the client needs be monitored because of the drug's greater systemic effects. The I.V. form is typically used when the inhaled beta2-adrenergic agonist doesn't work. A corticosteroid is slow acting, so its use won't reduce hypoxia in the acute phase.

A client with chronic obstructive pulmonary disease (COPD) is admitted to an acute care facility because of an acute respiratory infection. When assessing the client's respiratory status, which finding should the nurse anticipate?

An inspiratory-expiratory (I:E) ratio of 2:1 Explanation: The normal I:E ratio is 1:2, meaning that expiration takes twice as long as inspiration. A ratio of 2:1 is seen in clients with COPD because inspiration is shorter than expiration. A client with COPD typically has a barrel chest in which the anteroposterior diameter is larger than the transverse chest diameter. A client with COPD usually has a respiratory rate greater than 12 breaths/minute and an oxygen saturation rate below 93%.

A client has asthma. Which of the following medications is a commonly prescribed mast cell stabilizer used for asthma?

Cromolyn sodium Explanation: Cromolyn sodium and nedocromil are mild to moderate anti-inflammatory agents and are considered alternative medications for treatment. These medications stabilize mast cells. Albuterol is a long-acting beta2-antagonist. Budesonide is an inhaled corticosteroid. Theophylline is a mild to moderate bronchodilator

Which of the following is a common irritant that acts as a trigger of asthma?

Esophageal Reflux Disease

A client has chronic obstructive pulmonary disease (COPD) and is exhibiting shallow respirations of 32 breaths per minute, despite receiving nasal oxygen at 2 L/minute. To improve the client's shortness of breath, the nurse encourages the client to

Exhale slowly

A client has chronic obstructive pulmonary disease (COPD) and is exhibiting shallow respirations of 32 breaths per minute, despite receiving nasal oxygen at 2 L/minute. To improve the client's shortness of breath, the nurse encourages the client to

Exhale slowly Explanation: When a client with COPD exhibits shallow, rapid, and inefficient respirations, the nurse encourages the client to perform pursed-lip breathing, which includes exhaling slowly. Deep breaths or upper chest breathing is an inefficient breathing technique and should be changed to diaphragmatic breathing for the client with COPD. Some clients with COPD cannot tolerate much oxygen without developing hypercapnia.

A client being seen in the emergency department has labored respirations. Auscultation reveals inspiratory and expiratory wheezes. Oxygen saturation is 86%. The client was nonresponsive to an albuterol (Ventolin) inhaler and intravenous methylprednisolone (Solu-Medrol). The nurse administers the following prescribed treatment first:

Oxygen therapy through a non-rebreather mask

A client is being seen in the emergency department for exacerbation of chronic obstructive pulmonary disease (COPD). The first action of the nurse is to administer which of the following prescribed treatments?

Oxygen through nasal cannula at 2 L/minute

A client is being seen in the emergency department for exacerbation of chronic obstructive pulmonary disease (COPD). The first action of the nurse is to administer which of the following prescribed treatments?

Oxygen through nasal cannula at 2 L/minute Explanation: All options listed are treatments that may be used for a client with an exacerbation of COPD. The first line of treatment is oxygen therapy.

An increase in the red blood cell concentration in the blood is termed which of the following?

Polycythemia

An increase in the red blood cell concentration in the blood is termed which of the following?

Polycythemia Explanation: Polycythemia is an increase in the red blood cell concentration in the blood. Emphysema is a disease of the airways characterized by destruction of the walls of overdistended alveoli. Asthma is a disease with multiple precipitating mechanisms resulting in a common clinical outcome of reversible airflow obstruction.

In chronic obstructive pulmonary disease (COPD), decreased carbon dioxide elimination results in increased carbon dioxide tension in arterial blood, leading to which of the following acid-base imbalances?

Respiratory acidosis Explanation: Increased carbon dioxide tension in arterial blood leads to respiratory acidosis and chronic respiratory failure. In acute illness, worsening hypercapnia can lead to acute respiratory failure. The other acid-base imbalances would not correlate with COPD.

A client with chronic obstructive pulmonary disease (COPD) is recovering from a myocardial infarction. Because the client is extremely weak and can't produce an effective cough, the nurse should monitor closely for:

atelectasis. Explanation: In a client with COPD, an ineffective cough impedes secretion removal. This, in turn, causes mucus plugging, which leads to localized airway obstruction — a known cause of atelectasis. An ineffective cough doesn't cause pleural effusion (fluid accumulation in the pleural space). Pulmonary edema usually results from left-sided heart failure, not an ineffective cough. Although many noncardiac conditions may cause pulmonary edema, an ineffective cough isn't one of them. Oxygen toxicity results from prolonged administration of high oxygen concentrations, not an ineffective cough.

A nurse is caring for a client admitted with an exacerbation of asthma. The nurse knows the client's condition is worsening when he:

uses the sternocleidomastoid muscles. Explanation: Use of accessory muscles indicates worsening breathing conditions. Assuming the tripod position, a 93% pulse oximetry reading, and a request for the nurse to raise the head of the bed don't indicate that the client's condition is worsening.

The nurse is teaching the client about use of the pictured item with a metered-dose inhaler (MDI). The nurse instructs the client as follows: (Select all that apply.)

• Activate the MDI once. • The device may increase delivery of the MDI medication. • Take a slow, deep inhalation from the device.

After reviewing the pharmacological treatment for pulmonary diseases, the nursing student knows that bronchodilators relieve bronchospasm in three ways. Choose the correct three of the following options.

• Alter smooth muscle tone • Reduce airway obstruction • Increase oxygen distribution

Which of the following is a clinical manifestation of a pneumothorax? Select all that apply.

• Asymmetry of chest movement • Sudden chest pain • Oxygen desaturation • Unilateral retractions Explanation: Signs and symptoms of pneumothorax include sudden chest pain that is sharp and abrupt, a significant and sudden increase in shortness of breath, asymmetry of chest movement, unilateral retractions, bilateral differences in breath sounds, and/or oxygen desaturation. The patient with a pneumothorax would not have bilaterally equal breath sounds.

A nursing instructor is discussing asthma and its complications with medical-surgical nursing students. Which of the following would the group identify as complications of asthma? Choose all that apply.

• Atelectasis • Status asthmaticus • Respiratory failure Explanation: Complications of asthma may include status asthmaticus, respiratory failure, pneumonia, and atelectasis. Pertussis and pneumothorax are not complications.
