Asthma Flashcards
The nurse is caring for a client diagnosed with status asthmaticus who is currently not receiving any medical treatment. Which risk factor should the nurse consider for this client? (Select all that apply.) A. Alkalosis B. Hypercapnia C. Anxiety D. Hyperresonance E. Hyporeflexia
B, C, D
Rationale: The client who is not being treated for status asthmaticus is at risk for developing hypercapnia, hyperresonance, and anxiety. Acidosis occurs with status asthmaticus, not alkalosis. Hyporeflexia is not a condition that occurs if a client does not receive treatment for status asthmaticus.
The nurse is preparing to teach a client who is newly diagnosed with asthma on how to prevent asthma triggers. Which trigger should the nurse include in the teaching plan? (Select all that apply.) A. Cigarette smoke B. Mattress covers C. Indoor pets D. Stuffed animals E. Tile floors in the house
A, C, D
Rationale: Asthma triggers include cigarette smoke, indoor pets, and stuffed animals. Carpets, not tile floors, should be avoided as they can trigger asthma. Mattress covers should be used to decrease dust mites, which is a trigger for asthma.
Which clinical manifestation should the nurse expect to observe in the client with asthma? (Select all that apply.) A. Bradycardia B. Wheezing C. Dyspnea D. Retractions E. Cough
Answer: B, C, D, E
Rationale: Clinical manifestations associated with asthma include dyspnea, wheezing, cough, and retractions. Tachycardia, not bradycardia, is a clinical manifestation of asthma.
The nurse is examining a client newly diagnosed with asthma. Which pathological characteristic should the nurse expect in this client during physical examination? A. Dead space B. Air trapping C. Expiratory wheezing D. Increased lung volume
Answer: C
Rationale: On physical examination, there is expiratory wheezing that is often described as high pitched and musical, and there is prolongation of the expiratory phase of the respiratory cycle. Lung volumes are decreased. Air trapping and dead space occur in emphysema, not asthma.
The nurse is teaching a client who is newly diagnosed with asthma. Which manifestation of an asthma attack should the nurse include? A. Bradycardia B. Wheezing C. Chest pain D. Headache
B
Rationale: Wheezing occurs in asthma due to narrowing of airways. Chest pain and headaches are not a part of an asthma attack. Clients might exhibit tachycardia with an asthma attack, not bradycardia.
The nurse is discharging a client following a status asthmaticus episode. Which information should the nurse include in the asthma-teaching plan to prevent recurrence of episodes? (Select all that apply.)
A. Carrying a rapid-acting bronchodilator inhaler at all times
B. Getting a yearly influenza vaccination
C. Using the inhaled corticosteroid when shortness of breath occurs
D. Recommending that the client not be vaccinated for pneumonia
E. Avoiding breathing in strong odors and smoke
A, B, E
Rationale: Clients should be instructed to get vaccinated for both influenza and pneumonia and avoid asthma triggers such as strong odors and smoke. Inhaled corticosteroids do not act rapidly to reduce dyspnea. Rapid-acting bronchodilators are used to quickly open airways in an asthma attack and should be carried with the client at all times.
The nurse is teaching a client with asthma about peak flowmeter use. Which action by the client indicates that the teaching was successful?
A. The client anticipates using montelukast for readings in the red zone.
B. The client exhales slowly into the mouthpiece to obtain a reading.
C. The client uses the albuterol inhaler for peak flow readings in the yellow zone.
D. The client plans to contact the healthcare provider when the readings are in the green zone
C
Rationale: Readings in the yellow zone indicate a decrease in peak flow that should be treated with a short-acting beta2-adrenergic medication such as albuterol. Readings in the green zone indicate good asthma control, so there is no need to contact the healthcare provider. The client should be taught to exhale quickly and forcefully through the peak flowmeter mouthpiece to obtain the readings. Readings in the red zone do not indicate good peak flow, and the client should take a fast-acting bronchodilator and call the healthcare provider for further instructions. Montelukast is not indicated for acute attacks but rather is used for maintenance therapy.
A client has been taught how to use a peak flowmeter at home for asthma control. The daily peak flow is 75% of the baseline. Which action should the client take in this situation?
A. Go to the nearest emergency department for an evaluation.
B. Take her bronchodilator and recheck the peak flow.
C. Contact the healthcare provider.
D. Increase the dosage of daily corticosteroid and monitor her breathing.
B
Rationale: The client’s peak flow reading indicates that the condition is worsening, so she should take her bronchodilator and recheck the peak flow. Depending on whether she returns to the green zone, indicating well-controlled symptoms, or worsening to the red zone, the next step will be decided. If the symptoms continue to worsen, she should contact the healthcare provider or go to the emergency department. Increasing the dose of prescribed oral corticosteroid is not an appropriate treatment at this time.
The nurse is completing an admission history on a client with hypertension and possible asthma who is experiencing a new onset of wheezing and shortness of breath. Which information from the client’s health history may identify the cause of the asthma attack?
A. The client started a nonsteroidal anti-inflammatory drug (NSAID) 1 hour prior.
B. Two weeks ago, the client had an influenza vaccination.
C. The client took two acetaminophen (Tylenol) tablets for a headache that morning.
D. The client visited the zoo yesterday.
A
Rationale: Exposure to aspirin and nonsteroidal anti-inflammatory drugs can cause asthma. The other information in the health history, such as taking acetaminophen and getting an influenza vaccination, will not cause the asthma attack. If the trip to the zoo were going to trigger an attack, it would have happened yesterday while at the zoo or later in the evening following the trip.
The nurse is discharging a client who is newly diagnosed with asthma. Which topic should the nurse include in the discharge teaching? (Select all that apply.)
A. Side effects of theophylline
B. Complications associated with oxygen therapy
C. Self-administration of inhaled corticosteroids
D. When to contact the healthcare provider
E. How to use a peak flowmeter
C, D, E
Rationale: The nurse should teach the client the use of the peak flowmeter and when to contact the healthcare provider. The use of inhaled corticosteroids is more effective in improving asthma than any other drug and is indicated for all clients with persistent asthma. The other therapies, such as oxygen and theophylline, are not expected treatments for asthma.
A client is admitted in the emergency department for asthma. Which diagnostic and lab test should the nurse expect to be ordered? (Select all that apply.) A. Allergy skin testing B. Arterial blood gas C. Spirometry D. Pulse oximetry E. Peak expiratory flow
A, B, D, E
Rationale: Diagnostic tests that are appropriate for a client with asthma include peak expiratory flow, pulse oximetry, allergy skin testing, and arterial blood gas analysis. Spirometry can determine the extent of bronchospasm in clients with bronchitis, but not with asthma.
A client with a history of asthma presents with bradycardia and severe wheezing. Which action should be the nurse’s priority?
A. Preparing to assist with intubation and mechanical ventilation
B. Auscultating the lungs
C. Encouraging the client to cough and breathe deeply
D. Administering an intravenous (IV) corticosteroid
A
Rationale: The client’s clinical manifestation indicates impending respiratory failure and immediate action is required, so the nurse should notify the healthcare provider. The nurse should prepare to assist with intubation and mechanical ventilation after notifying the healthcare provider. IV corticosteroids require several hours before having any effect on respiratory status. Auscultation, coughing, and deep breathing will not help this client.
A client who is experiencing an acute asthma attack is brought to the emergency department. Which action should the nurse take first?
A. Administer an inhaled corticosteroid.
B. Obtain a peak flowmeter reading.
C. Auscultate the client’s lungs.
D. Determine when the shortness of breath began.
C
Rationale: Assessment of the client’s lungs will help determine how effectively the client is ventilating and whether rapid intubation may be necessary. The length of time the attack has persisted is not as important as determining the current status. During an acute attack, most clients are unable to use a peak flowmeter. Medication administration should be done following the assessment.
A client calls the clinic nurse and reports the following readings: baseline peak flow of 600 L/min and the current peak flow of 420 L/min. Which instruction should the nurse give this client?
A. Notify the healthcare provider.
B. Use the albuterol (bronchodilator) inhaler.
C. Avoid any asthma triggers and repeat the peak flow testing.
D. Go to the closest emergency department.
B
Rationale: The client’s peak flow is 70% of normal, which is the yellow zone. This indicates a need for immediate use of short-acting beta-adrenergic medications. Advising the client to avoid exposure to allergens is important but would not address the current decrease in peak flow. Because the client is currently in the yellow zone, notifying the healthcare provider and hospitalization are not immediately needed.
The nurse is evaluating the oxygenation status of a client during an asthma attack. Which diagnostic tool should be most useful for gathering this information? A. Cardiac monitor B. Chest x-ray C. Pulse oximetry D. Peak flowmeter
C
Rationale: The nurse should use pulse oximetry to determine the client’s oxygen saturation. The goal for treatment of an asthma attack is to keep the oxygen saturation greater than 90%. Viewing the heart rate and rhythm, chest x-ray, and knowing the measurements for the peak flow reading do not indicate if the client has good oxygenation status.
