Comprehensive Unit 3 Questions Pt 1

A client is on Advair (fluticasone and salmeterol) for asthma. What is an important piece of information they should know? Answers: A. That it can increase the risk of death B. That it contains a short acting beta agonist C. It can increase the risk of lactic acidosis D. It is best used only several times a week

A Advair is a combination of a long acting beta agonist and a steroid. It is effective at treating asthma and widely used, but some data indicates that it can increase the risk of death.

A male client who weighs 175 lb (79.4 kg) is receiving aminophylline (Aminophyllin) (400 mg in 500 ml) at 50 ml/hour. The theophylline level is reported as 6 mcg/ml. The nurse calls the physician who instructs the nurse to change the dosage to 0.45 mg/kg/hour. The nurse should: A. Question the order because it's too low. B. Question the order because it's too high. C. Set the pump at 45 ml/hour. D. Stop the infusion and have the laboratory repeat the theophylline measurement.

A. A therapeutic theophylline level is 10 to 20 mcg/ml. The client is currently receiving 0.5 mg/kg/hour of aminophylline. Because the client's theophylline level is sub-therapeutic, reducing the dose (which is what the physician's order would do) would be inappropriate. Therefore, the nurse should question the order.

A male client comes to the emergency department complaining of sudden onset of diarrhea, anorexia, malaise, cough, headache, and recurrent chills. Based on the client's history and physical findings, the physician suspects legionnaires' disease. While awaiting diagnostic test results, the client is admitted to the facility and started on antibiotic therapy. What is the drug of choice for treating legionnaires' disease? A. Erythromycin (Erythrocin) B. Rifampin (Rifadin) C. Amantadine (Symmetrel) D. Amphotericin B (Fungizone)

A. Erythromycin is the drug of choice for treating legionnaires' disease. Rifampin may be added to the regimen if erythromycin alone is ineffective; however, it isn't administered first. Amantadine, an antiviral agent, and amphotericin B, an antifungal agent, are ineffective against legionnaires' disease, which is caused by bacterial infection.

For a male client with an endotracheal (ET) tube, which nursing action is most essential? A. Auscultating the lungs for bilateral breath sounds B. Turning the client from side to side every 2 hours C. Monitoring serial blood gas values every 4 hours D. Providing frequent oral hygiene

A. For a client with an ET tube, the most important nursing action is auscultating the lungs regularly for bilateral breath sounds to ensure proper tube placement and effective oxygen delivery. Although the other options are appropriate for this client, they're secondary to ensuring adequate oxygenation.

A male client admitted to an acute care facility with pneumonia is receiving supplemental oxygen, 2 L/minute via nasal cannula. The client's history includes chronic obstructive pulmonary disease (COPD) and coronary artery disease. Because of these history findings, the nurse closely monitors the oxygen flow and the client's respiratory status. Which complication may arise if the client receives a high oxygen concentration? A. Apnea B. Anginal pain C. Respiratory alkalosis D. Metabolic acidosis

A. Hypoxia is the main breathing stimulus for a client with COPD. Excessive oxygen administration may lead to apnea by removing that stimulus. Anginal pain results from a reduced myocardial oxygen supply. A client with COPD may have anginal pain from generalized vasoconstriction secondary to hypoxia; however, administering oxygen at any concentration dilates blood vessels, easing anginal pain. Respiratory alkalosis results from alveolar hyperventilation, not excessive oxygen administration. In a client with COPD, high oxygen concentrations decrease the ventilatory drive, leading to respiratory acidosis, not alkalosis. High oxygen concentrations don't cause metabolic acidosis.

The nurse in charge is teaching a client with emphysema how to perform pursed-lip breathing. The client asks the nurse to explain the purpose of this breathing technique. Which explanation should the nurse provide? A. It helps prevent early airway collapse. B. It increases inspiratory muscle strength. C. It decreases use of accessory breathing muscles. D. It prolongs the inspiratory phase of respiration.

A. Pursed-lip breathing helps prevent early airway collapse. Learning this technique helps the client control respiration during periods of excitement, anxiety, exercise, and respiratory distress. To increase inspiratory muscle strength and endurance, the client may need to learn inspiratory resistive breathing. To decrease accessory muscle use and thus reduce the work of breathing, the client may need to learn diaphragmatic (abdominal) breathing. In pursed-lip breathing, the client mimics a normal inspiratory-expiratory (I:E) ratio of 1:2. (A client with emphysema may have an I:E ratio as high as 1:4.)

Nurse Oliver is caring for a client immediately after removal of the endotracheal tube. The nurse reports which of the following signs immediately if experienced by the client? A. Stridor B. Occasional pink-tinged sputum C. A few basilar lung crackles on the right D. Respiratory rate 24 breaths/min

A. The nurse reports stridor to the physician immediately. This is a high-pitched, coarse sound that is heard with the stethoscope over the trachea. Stridor indicates airway edema and places the client at risk for airway obstruction. Options B, C, and D are not signs that require immediate notification of the physician.

The nurse evaluates that nursing interventions to promote airway clearance in a patient admitted with COPD are successful based on which finding? Absence of dyspnea Improved mental status Effective and productive coughing PaO2 within normal range for the patient

Airway clearance is most directly evaluated as successful if the patient can engage in effective and productive coughing. Absence of dyspnea, improved mental status, and PaO2 within normal range for the patient show improved respiratory status but do not evaluate airway clearance.

The patient has an order for each of the following inhalers. Which one should the nurse offer to the patient at the onset of an asthma attack? Albuterol (Proventil) Salmeterol (Serevent) Beclomethasone (Qvar) Ipratropium bromide (Atrovent)

Albuterol is a short-acting bronchodilator that should be given initially when the patient experiences an asthma attack. Salmeterol (Serevent) is a long-acting β2-adrenergic agonist, which is not used for acute asthma attacks. Beclomethasone (Qvar) is a corticosteroid inhaler and not recommended for an acute asthma attack. Ipratropium bromide (Atrovent) is an anticholinergic agent that is less effective than β2-adrenergic agonists. It may be used in an emergency with a patient unable to tolerate short-acting β2-adrenergic agonists (SABAs).

The nurse determines that the patient is not experiencing adverse effects of albuterol (Proventil) after noting which patient vital sign? Pulse rate of 72/minute Temperature of 98.4° F Oxygen saturation 96% Respiratory rate of 18/minute

Albuterol is a β2-agonist that can sometimes cause adverse cardiovascular effects. These would include tachycardia and angina. A pulse rate of 72 indicates that the patient did not experience tachycardia as an adverse effect.

When admitting a patient with a diagnosis of asthma exacerbation, the nurse will assess for what potential triggers (select all that apply)? Exercise Allergies Emotional stress Decreased humidity Upper respiratory infections

Although the exact mechanism of asthma is unknown, there are several triggers that may precipitate an attack. These include allergens, exercise, air pollutants, upper respiratory infections, drug and food additives, psychologic factors, and gastroesophageal reflux disease (GERD).

A 45-year-old man with asthma is brought to the emergency department by automobile. He is short of breath and appears frightened. During the initial nursing assessment, which clinical manifestation might be present as an early manifestation during an exacerbation of asthma? Anxiety Cyanosis Bradycardia Hypercapnia

An early manifestation during an asthma attack is anxiety because the patient is acutely aware of the inability to get sufficient air to breathe. He will be hypoxic early on with decreased PaCO2 and increased pH as he is hyperventilating. If cyanosis occurs, it is a later sign. The pulse and blood pressure will be increased.

When admitting a 45-year-old female with a diagnosis of pulmonary embolism, the nurse will assess the patient for which risk factors (select all that apply)? Obesity Pneumonia Malignancy Cigarette smoking Prolonged air travel

An increased risk of pulmonary embolism is associated with obesity, malignancy, heavy cigarette smoking, and prolonged air travel with reduced mobility. Other risk factors include deep vein thrombosis, immobilization, surgery within the last 3 months, oral contraceptives and hormone therapy, heart failure, pregnancy, and clotting disorders.

A male adult client is suspected of having a pulmonary embolus. A nurse assesses the client, knowing that which of the following is a common clinical manifestation of pulmonary embolism? A. Dyspnea B. Bradypnea C. Bradycardia D. Decreased respirations

Answer A. The common clinical manifestations of pulmonary embolism are tachypnea, tachycardia, dyspnea, and chest pain.

An oxygen delivery system is prescribed for a male client with chronic obstructive pulmonary disease to deliver a precise oxygen concentration. Which of the following types of oxygen delivery systems would the nurse anticipate to be prescribed? A. Face tent B. Venturi mask C. Aerosol mask D. Tracheostomy collar

B. The Venturi mask delivers the most accurate oxygen concentration. It is the best oxygen delivery system for the client with chronic airflow limitation because it delivers a precise oxygen concentration. The face tent, aerosol mask, and tracheostomy collar are also high-flow oxygen delivery systems but most often are used to administer high humidity.

What is important to know about emphysema? Answers: A. It's a complication of asthma B. It's a form of COPD C. It's a respiratory condition caused by bacteria D. It can only be reversed within a year or two of onset

B Emphysema is a form of COPD. It is caused by a variety of issues, in particular smoking. It cannot be reversed.

A male client abruptly sits up in bed, reports having difficulty breathing and has an arterial oxygen saturation of 88%. Which mode of oxygen delivery would most likely reverse the manifestations? A. Simple mask B. Non-rebreather mask C. Face tent D. Nasal cannula

B. A non-rebreather mask can deliver levels of the fraction of inspired oxygen (FIO2) as high as 100%. Other modes — simple mask, face tent, and nasal cannula — deliver lower levels of FIO2.

Dr. Jones prescribes albuterol sulfate (Proventil) for a patient with newly diagnose asthma. When teaching the patient about this drug, the nurse should explain that it may cause: A. Nasal congestion B. Nervousness C. Lethargy D. Hyperkalemia

B. Albuterol may cause nervousness. The inhaled form of the drug may cause dryness and irritation of the nose and throat, not nasal congestion; insomnia, not lethargy; and hypokalemia (with high doses), not hyperkalemia. Otther adverse effects of albuterol include tremor, dizziness, headache, tachycardia, palpitations, hypertension, heartburn, nausea, vomiting and muscle cramps.

The nurse in charge formulates a nursing diagnosis of Activity intolerance related to inadequate oxygenation and dyspnea for a client with chronic bronchitis. To minimize this problem, the nurse instructs the client to avoid conditions that increase oxygen demands. Such conditions include: A. Drinking more than 1,500 ml of fluid daily. B. Being overweight. C. Eating a high-protein snack at bedtime. D. Eating more than three large meals a day.

B. Conditions that increase oxygen demands include obesity, smoking, exposure to temperature extremes, and stress. A client with chronic bronchitis should drink at least 2,000 ml of fluid daily to thin mucus secretions; restricting fluid intake may be harmful. The nurse should encourage the client to eat a high-protein snack at bedtime because protein digestion produces an amino acid with sedating effects that may ease the insomnia associated with chronic bronchitis. Eating more than three large meals a day may cause fullness, making breathing uncomfortable and difficult; however, it doesn't increase oxygen demands. To help maintain adequate nutritional intake, the client with chronic bronchitis should eat small, frequent meals (up to six a day).

Nurse Reynolds caring for a client with a chest tube turns the client to the side, and the chest tube accidentally disconnects. The initial nursing action is to: A. Call the physician B. Place the tube in bottle of sterile water C. Immediately replace the chest tube system D. Place a sterile dressing over the disconnection site

B. If the chest drainage system is disconnected, the end of the tube is placed in a bottle of sterile water held below the level of the chest. The system is replaced if it breaks or cracks or if the collection chamber is full. Placing a sterile dressing over the disconnection site will not prevent complications resulting from the disconnection. The physician may need to be notified, but this is not the initial action.

A nurse is caring for a male client with emphysema who is receiving oxygen. The nurse assesses the oxygen flow rate to ensure that it does not exceed: A. 1 L/min B. 2 L/min C. 6 L/min D. 10 L/min

B. Oxygen is used cautiously and should not exceed 2 L/min. Because of the long-standing hypercapnia that occurs in emphysema, the respiratory drive is triggered by low oxygen levels rather than increased carbon dioxide levels, as is the case in a normal respiratory system.

A black client with asthma seeks emergency care for acute respiratory distress. Because of this client's dark skin, the nurse should assess for cyanosis by inspecting the: A. Lips. B. Mucous membranes. C. Nail beds. D. Earlobes.

B. Skin color doesn't affect the mucous membranes. The lips, nail beds, and earlobes are less reliable indicators of cyanosis because they're affected by skin color.

Nurse Maureen has assisted a physician with the insertion of a chest tube. The nurse monitors the client and notes fluctuation of the fluid level in the water seal chamber after the tube is inserted. Based on this assessment, which action would be appropriate? A. Inform the physician B. Continue to monitor the client C. Reinforce the occlusive dressing D. Encourage the client to deep-breathe

B. The presence of fluctuation of the fluid level in the water seal chamber indicates a patent drainage system. With normal breathing, the water level rises with inspiration and falls with expiration. Fluctuation stops if the tube is obstructed, if a dependent loop exists, if the suction is not working properly, or if the lung has reexpanded. Options A, C, and D are incorrect.

The nurse assesses a male client's respiratory status. Which observation indicates that the client is experiencing difficulty breathing? A. Diaphragmatic breathing B. Use of accessory muscles C. Pursed-lip breathing D. Controlled breathing

B. The use of accessory muscles for respiration indicates the client is having difficulty breathing. Diaphragmatic and pursed-lip breathing are two controlled breathing techniques that help the client conserve energy.

An emergency room nurse is assessing a male client who has sustained a blunt injury to the chest wall. Which of these signs would indicate the presence of a pneumothorax in this client? A. A low respiratory rate B. Diminished breath sounds C. The presence of a barrel chest D. A sucking sound at the site of injury

B. This client has sustained a blunt or a closed chest injury. Basic symptoms of a closed pneumothorax are shortness of breath and chest pain. A larger pneumothorax may cause tachypnea, cyanosis, diminished breath sounds, and subcutaneous emphysema. Hyperresonance also may occur on the affected side. A sucking sound at the site of injury would be noted with an open chest injury.

A nurse is preparing to obtain a sputum specimen from a male client. Which of the following nursing actions will facilitate obtaining the specimen? A. Limiting fluid B. Having the client take deep breaths C. Asking the client to spit into the collection container D. Asking the client to obtain the specimen after eating

B. To obtain a sputum specimen, the client should rinse the mouth to reduce contamination, breathe deeply, and then cough into a sputum specimen container. The client should be encouraged to cough and not spit so as to obtain sputum. Sputum can be thinned by fluids or by a respiratory treatment such as inhalation of nebulized saline or water. The optimal time to obtain a specimen is on arising in the morning.

When caring for a patient with chronic obstructive pulmonary disease (COPD), the nurse identifies a nursing diagnosis of imbalanced nutrition: less than body requirements after noting a weight loss of 30 lb. Which intervention should the nurse add to the plan of care for this patient? Order fruits and fruit juices to be offered between meals. Order a high-calorie, high-protein diet with six small meals a day. Teach the patient to use frozen meals at home that can be microwaved. Provide a high-calorie, high-carbohydrate, nonirritating, frequent feeding diet.

Because the patient with COPD needs to use greater energy to breathe, there is often decreased oral intake because of dyspnea. A full stomach also impairs the ability of the diaphragm to descend during inspiration, thus interfering with the work of breathing. For these reasons, the patient with COPD should eat six small meals per day taking in a high-calorie, high-protein diet, with non-protein calories divided evenly between fat and carbohydrate. The other interventions will not increase the patient's caloric intake.

During an assessment of a 45-year-old patient with asthma, the nurse notes wheezing and dyspnea. The nurse interprets that these symptoms are related to what pathophysiologic change? a. Laryngospasm b. Pulmonary edema c. Narrowing of the airway d. Overdistention of the alveoli

C Narrowing of the airway by persistent but variable inflammation leads to reduced airflow, making it difficult for the patient to breathe and producing the characteristic wheezing. Laryngospasm, pulmonary edema, and overdistention of the alveoli do not produce wheezing.

Nurse Oliver observes constant bubbling in the water-seal chamber of a closed chest drainage system. What should the nurse conclude? A. The system is functioning normally B. The client has a pneumothorax. C. The system has an air leak. D. The chest tube is obstructed.

C. Constant bubbling in the chamber indicates an air leak and requires immediate intervention. The client with a pneumothorax will have intermittent bubbling in the water-seal chamber. Clients without a pneumothorax should have no evidence of bubbling in the chamber. If the tube is obstructed, the nurse should notice that the fluid has stopped fluctuating in the water-seal chamber.

For a female patient with chronic obstructive pulmonary disease, which nursing intervention would help maintain a patent airway? A. Restricting fluid intake to 1,000 ml per day B. Enforcing absolute bed rest C. Teaching the patient how to perform controlled coughing D. Administering prescribe sedatives regularly and in large amounts

C. Controlled coughing helps maintain a patent airway by helping to mobilize and remove secretions. A moderate fluid intake (usually 2 L or more daily) and moderate activity help liquefy and mobilize secretions. Bed rest and sedatives may limit the patient's ability to maintain a patent airway, causing a high risk for infection from pooled secretions.

A male 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: A. Pleural effusion. B. Pulmonary edema. C. Atelectasis. D. Oxygen toxicity.

C. 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.

The nurse is teaching a male client with chronic bronchitis about breathing exercises. Which of the following should the nurse include in the teaching? A. Make inhalation longer than exhalation. B. Exhale through an open mouth. C. Use diaphragmatic breathing. D. Use chest breathing.

C. In chronic bronchitis the diaphragm is flat and weak. Diaphragmatic breathing helps to strengthen the diaphragm and maximizes ventilation. Exhalation should be longer than inhalation to prevent collapse of the bronchioles. The client with chronic bronchitis should exhale through pursed lips to prolong exhalation, keep the bronchioles from collapsing, and prevent air trapping. Diaphragmatic breathing — not chest breathing — increases lung expansion.

What should the nurse inspect when assessing a patient with shortness of breath for evidence of long-standing hypoxemia? Chest excursion Spinal curvatures Respiratory pattern Fingernails and their base

Clubbing, a sign of long-standing hypoxemia, is evidenced by an increase in the angle between the base of the nail and the fingernail to 180 degrees or more, usually accompanied by an increase in the depth, bulk, and sponginess of the end of the finger.

The nurse evaluates that a patient is experiencing the expected beneficial effects of ipratropium (Atrovent) after noting which assessment finding? Decreased respiratory rate Increased respiratory rate Increased peak flow readings Decreased sputum production

Ipratropium is a bronchodilator that should result in increased peak expiratory flow rates (PEFRs).

The nurse, who has administered a first dose of oral prednisone to a patient with asthma, writes on the care plan to begin monitoring for which patient parameters? Apical pulse Daily weight Bowel sounds Deep tendon reflexes

Corticosteroids such as prednisone can lead to weight gain. For this reason, it is important to monitor the patient's daily weight. The drug should not affect the apical pulse, bowel sounds, or deep tendon reflexes.

Why would a Venturi mask be used? Choose the answer that is most correct Answers: A. In treating influenza B. To lower risk of infection when treating certain clients C. To provide reactive support D. When high flow oxygen is needed

D A Venturi mask is used to provide high flow oxygen support.

A male patient is admitted to the health care facility for treatment of chronic obstructive pulmonary disease. Which nursing diagnosis is most important for this patient? A. Activity intolerance related to fatigue B. Anxiety related to actual threat to health status C. Risk for infection related to retained secretions D. Impaired gas exchange related to airflow obstruction

D. A patient airway and an adequate breathing pattern are the top priority for any patient, making "impaired gas exchange related to airflow obstruction" the most important nursing diagnosis. The other options also may apply to this patient but less important.

A client with Guillain-Barré syndrome develops respiratory acidosis as a result of reduced alveolar ventilation. Which combination of arterial blood gas (ABG) values confirms respiratory acidosis? A. pH, 5.0; PaCO2 30 mm Hg B. pH, 7.40; PaCO2 35 mm Hg C. pH, 7.35; PaCO2 40 mm Hg D. pH, 7.25; PaCO2 50 mm Hg

D. In respiratory acidosis, ABG analysis reveals an arterial pH below 7.35 and partial pressure of arterial carbon dioxide (PaCO2) above 45 mm Hg. Therefore, the combination of a pH value of 7.25 and a PaCO2 value of 50 mm Hg confirms respiratory acidosis. A pH value of 5.0 with a PaCO2 value of 30 mm Hg indicates respiratory alkalosis. Options B and C represent normal ABG values, reflecting normal gas exchange in the lungs.

A nurse instructs a female client to use the pursed-lip method of breathing and the client asks the nurse about the purpose of this type of breathing. The nurse responds, knowing that the primary purpose of pursed-lip breathing is to: A. Promote oxygen intake B. Strengthen the diaphragm C. Strengthen the intercostal muscles D. Promote carbon dioxide elimination

D. Pursed-lip breathing facilitates maximal expiration for clients with obstructive lung disease. This type of breathing allows better expiration by increasing airway pressure that keeps air passages open during exhalation. Options A, B, and C are not the purposes of this type of breathing.

At 11 p.m., a male client is admitted to the emergency department. He has a respiratory rate of 44 breaths/minute. He's anxious, and wheezes are audible. The client is immediately given oxygen by face mask and methylprednisolone (Depo-medrol) I.V. At 11:30 p.m., the client's arterial blood oxygen saturation is 86% and he's still wheezing. The nurse should plan to administer: A. Alprazolam (Xanax). B. Propranolol (Inderal) C. Morphine. D. Albuterol (Proventil).

D. The client is hypoxemic because of bronchoconstriction as evidenced by wheezes and a subnormal arterial oxygen saturation level. The client's greatest need is bronchodilation, which can be accomplished by administering bronchodilators. Albuterol is a beta2 adrenergic agonist, which causes dilation of the bronchioles. It's given by nebulization or metered-dose inhalation and may be given as often as every 30 to 60 minutes until relief is accomplished. Alprazolam is an anxiolytic and central nervous system depressant, which could suppress the client's breathing. Propranolol is contraindicated in a client who's wheezing because it's a beta2 adrenergic antagonist. Morphine is a respiratory center depressant and is contraindicated in this situation.

A male adult patient hospitalized for treatment of a pulmonary embolism develops respiratory alkalosis. Which clinical findings commonly accompany respiratory alkalosis? A. Nausea or vomiting B. Abdominal pain or diarrhea C. Hallucinations or tinnitus D. Lightheadedness or paresthesia

D. The patient with respiratory alkalosis may complain of lightheadedness or paresthesia (numbness and tingling in the arms and legs). Nausea, vomiting, abdominal pain, and diarrhea may accompany respiratory acidosis. Hallucinations and tinnitus rare are associated with respiratory alkalosis or any other acid-base imbalance.

Nurse Ruth assessing a patient for tracheal displacement should know that the trachea will deviate toward the: A. Contralateral side in a simple pneumothorax B. Affected side in a hemothorax C. Affected side in a tension pneumothorax D. Contralateral side in hemothorax

D. The trachea will shift according to the pressure gradients within the thoracic cavity. In tension pneumothorax and hemothorax, accumulation of air or fluid causes a shift away from the injured side. If there is no significant air or fluid accumulation, the trachea will not shift. Tracheal deviation toward the contralateral side in simple pneumothorax is seen when the thoracic contents shift in response to the release of normal thoracic pressure gradients on the injured side.

When planning teaching for the patient with chronic obstructive pulmonary disease (COPD), the nurse understands that what causes the manifestations of the disease? An overproduction of the antiprotease α1 -antitrypsin Hyperinflation of alveoli and destruction of alveolar walls Hypertrophy and hyperplasia of goblet cells in the bronchi Collapse and hypoventilation of the terminal respiratory unit

In COPD there are structural changes that include hyperinflation of alveoli, destruction of alveolar walls, destruction of alveolar capillary walls, narrowing of small airways, and loss of lung elasticity. An autosomal recessive deficiency of antitrypsin may cause COPD. Not all patients with COPD have excess mucus production by the increased number of goblet cells.

The nurse is teaching a patient how to self-administer ipratropium (Atrovent) via a metered dose inhaler (MDI). Which instruction given by the nurse is most appropriate to help the patient learn the proper inhalation technique? "Avoid shaking the inhaler before use." "Breathe out slowly before positioning the inhaler." "Using a spacer should be avoided for this type of medication." "After taking a puff, hold the breath for 30 seconds before exhaling."

It is important to breathe out slowly before positioning the inhaler. This allows the patient to take a deeper breath while inhaling the medication, thus enhancing the effectiveness of the dose. The inhaler should be shaken well. A spacer may be used. Holding the breath after the inhalation of medication helps keep the medication in the lungs, but 30 seconds will not be possible for a patient with COPD.

While teaching a patient with asthma about the appropriate use of a peak flow meter, what should the nurse instruct the patient to do? Keep a record of the peak flow meter numbers if symptoms of asthma are getting worse. Use the flow meter each morning after taking medications to evaluate their effectiveness. Increase the doses of the long-term control medication if the peak flow numbers decrease. Empty the lungs and then inhale quickly through the mouthpiece to measure how fast air can be inhaled.

It is important to keep track of peak flow readings daily, especially when the patient's symptoms are getting worse. The patient should have specific directions as to when to call the physician based on personal peak flow numbers. Peak flow is measured by exhaling into the flow meter and should be assessed before and after medications to evaluate their effectiveness.

The nurse is evaluating if a patient understands how to safely determine whether a metered dose inhaler (MDI) is empty. The nurse interprets that the patient understands this important information to prevent medication underdosing when the patient describes which method to check the inhaler? Place it in water to see if it floats. Keep track of the number of inhalations used. Shake the canister while holding it next to the ear Check the indicator line on the side of the canister.

It is no longer appropriate to see if a canister floats in water or not since this is not an accurate way to determine the remaining inhaler doses. The best method to determine when to replace an inhaler is by knowing the maximum puffs available per MDI and then replacing it after the number of days when those inhalations have been used. (100 puffs/2 puffs each day = 50 days)

A patient has been receiving oxygen per nasal cannula while hospitalized for COPD. The patient asks the nurse whether oxygen use will be needed at home. What is the most appropriate response by the nurse? "Long-term home oxygen therapy should be used to prevent respiratory failure." "Oxygen will not be needed until or unless you are in the terminal stages of this disease." "Long-term home oxygen therapy should be used to prevent heart problems related to COPD." "You will not need oxygen until your oxygen saturation drops to 88% and you have symptoms of hypoxia."

Long-term oxygen therapy in the home will not be considered until the oxygen saturation is less than or equal to 88% and the patient has signs of tissue hypoxia, such as cor pulmonale, erythrocytosis, or impaired mental status. PaO2 less than 55 mm Hg will also allow home oxygen therapy to be considered.

Which test result identifies that a patient with asthma is responding to treatment? An increase in CO2 levels A decreased exhaled nitric oxide A decrease in white blood cell count An increase in serum bicarbonate levels

Nitric oxide levels are increased in the breath of people with asthma. A decrease in the exhaled nitric oxide concentration suggests that the treatment may be decreasing the lung inflammation associated with asthma and adherence to treatment. An increase in CO2 levels, decreased white blood cell count, and increased serum bicarbonate levels do not indicate a positive response to treatment in the asthma patient.

The patient had abdominal surgery yesterday. Today the lung sounds in the lower lobes have decreased. The nurse knows this could be due to what occurring? Pain Atelectasis Pneumonia Pleural effusion

Postoperatively there is an increased risk for atelectasis from anesthesia as well as restricted breathing from pain. Without deep breathing to stretch the alveoli, surfactant secretion to hold the alveoli open is not promoted. Pneumonia will occur later after surgery. Pleural effusion occurs because of blockage of lymphatic drainage or an imbalance between intravascular and oncotic fluid pressures, which is not expected in this case.

A patient with an acute exacerbation of chronic obstructive pulmonary disease (COPD) needs to receive precise amounts of oxygen. Which equipment should the nurse prepare to use? Oxygen tent Venturi mask Nasal cannula Oxygen-conserving cannula

The Venturi mask delivers precise concentrations of oxygen and should be selected whenever this is a priority concern. The other methods are less precise in terms of amount of oxygen delivered.

Which position is most appropriate for the nurse to place a patient experiencing an asthma exacerbation? Supine Lithotomy High Fowler's Reverse Trendelenburg

The patient experiencing an asthma attack should be placed in high Fowler's position and may need to lean forward to allow for optimal chest expansion and enlist the aid of gravity during inspiration. The supine, lithotomy, and reverse Trendelenburg positions will not facilitation ventilation.

When teaching the patient with cystic fibrosis about the diet and medications, what is the priority information to be included in the discussion? Fat soluble vitamins and dietary salt should be avoided. Insulin may be needed with a diabetic diet if diabetes mellitus develops. Pancreatic enzymes and adequate fat, calories, protein, and vitamins are needed. Distal intestinal obstruction syndrome (DIOS) can be treated with increased water.

The patient must take pancreatic enzymes before each meal and snack and adequate fat, calories, protein, and vitamins should be eaten. Fat-soluble vitamins are needed because they are malabsorbed with the excess mucus in the gastrointestinal system. Insulin may be needed, but there is no longer a diabetic diet, and this is not priority information at this time. DIOS develops in the terminal ileum and is treated with balanced polyethylene glycol electrolyte solution (MiraLAX) to thin bowel contents.

Which statement made by the patient with chronic obstructive pulmonary disease (COPD) indicates a need for further teaching regarding the use of an ipratropium inhaler? "I can rinse my mouth following the two puffs to get rid of the bad taste." "I should wait at least 1 to 2 minutes between each puff of the inhaler." "Because this medication is not fast-acting, I cannot use it in an emergency if my breathing gets worse." "If my breathing gets worse, I should keep taking extra puffs of the inhaler until I can breathe more easily.

The patient should not just keep taking extra puffs of the inhaler to make breathing easier. Excessive treatment could trigger paradoxical bronchospasm, which would worsen the patient's respiratory status. Rinsing the mouth after the puffs will eliminate a bad taste. Waiting 1 to 2 minutes between each puff will facilitate the effectiveness of the administration. Ipratropium is not used in an emergency for COPD.

Before discharge, the nurse discusses activity levels with a 61-year-old patient with chronic obstructive pulmonary disease (COPD) and pneumonia. Which exercise goal is most appropriate once the patient is fully recovered from this episode of illness? Slightly increase activity over the current level. Swim for 10 min/day, gradually increasing to 30 min/day. Limit exercise to activities of daily living to conserve energy. Walk for 20 min/day, keeping the pulse rate less than 130 beats/min.

The patient will benefit from mild aerobic exercise that does not stress the cardiorespiratory system. The patient should be encouraged to walk for 20 min/day, keeping the pulse rate less than 75% to 80% of maximum heart rate (220 - patient's age).

A male patient with COPD becomes dyspneic at rest. His baseline blood gas results are PaO2 70 mm Hg, PaCO2 52 mm Hg, and pH 7.34. What updated patient assessment requires the nurse's priority intervention? Arterial pH 7.26 PaCO2 50 mm Hg Patient in tripod position Increased sputum expectoration

The patient's pH shows acidosis that supports an exacerbation of COPD along with the worsening dyspnea. The PaCO2 has improved from baseline, the tripod position helps the patient's breathing, and the increase in sputum expectoration will improve the patient's ventilation.

The nurse teaches pursed lip breathing to a patient who is newly diagnosed with chronic obstructive pulmonary disease (COPD). The nurse reinforces that this technique will assist respiration by which mechanism? Loosening secretions so that they may be coughed up more easily Promoting maximal inhalation for better oxygenation of the lungs Preventing bronchial collapse and air trapping in the lungs during exhalation Increasing the respiratory rate and giving the patient control of respiratory patterns

The purpose of pursed lip breathing is to slow down the exhalation phase of respiration, which decreases bronchial collapse and subsequent air trapping in the lungs during exhalation. It does not affect secretions, inhalation, or increase the rate of breathing.

When teaching the patient with bronchiectasis about manifestations to report to the health care provider, which manifestation should be included? Increasing dyspnea Temperature below 98.6° F Decreased sputum production Unable to drink 3 L low-sodium fluids

The significant clinical manifestations to report to the health care provider include increasing dyspnea, fever, chills, increased sputum production, bloody sputum, and chest pain. Although drinking at least 3 L of low-sodium fluid will help liquefy secretions to make them easier to expectorate, the health care provider does not need to be notified if the patient cannot do this one day.

The nurse identifies the nursing diagnosis of activity intolerance for a patient with asthma. In patients with asthma, the nurse assesses for which etiologic factor for this nursing diagnosis? Work of breathing Fear of suffocation Effects of medications Anxiety and restlessness

When the patient does not have sufficient gas exchange to engage in activity, the etiologic factor is often the work of breathing. When patients with asthma do not have effective respirations, they use all available energy to breathe and have little left over for purposeful activity. Fear of suffocation, effects of medications or anxiety, and restlessness are not etiologies for activity intolerance for a patient with asthma.

The patient's arterial blood gas results show the PaO2 at 65 mmHg and the SaO2 at 80%. What early manifestations should the nurse expect to observe in this patient? Restlessness, tachypnea, tachycardia, and diaphoresis Unexplained confusion, dyspnea at rest, hypotension, and diaphoresis Combativeness, retractions with breathing, cyanosis, and decreased output Coma, accessory muscle use, cool and clammy skin, and unexplained fatigue

With inadequate oxygenation, early manifestations include restlessness, tachypnea, tachycardia, and diaphoresis, decreased urinary output, and unexplained fatigue. The unexplained confusion, dyspnea at rest, hypotension, and diaphoresis; combativeness, retractions with breathing, cyanosis, and decreased urinary output; coma, accessory muscle use, cool and clammy skin, and unexplained fatigue occur as later manifestations of inadequate oxygenation.
