Question

A client arrives at the emergency department with increasing shortness of breath, productive cough, and wheezing for the past 3 days.

Answer 1

Correct Answers:

Prolonged expiratory phase with wheezing
Productive cough with yellow-green sputum
Sp02 86% on room air

Rationale :

🫁A prolonged expiratory phase with wheezing reflects airflow obstruction and bronchospasm during an acute COPD exacerbation.

🦠A yellow-green productive cough indicates increased sputum volume and purulence, commonly associated with an infectious trigger.

📉An SpO₂ of 86% demonstrates clinically significant hypoxemia caused by worsening ventilation-perfusion imbalance.

🚨Together, these findings indicate an acute deterioration from the client’s underlying chronic pulmonary disease.

📌Core Message:

An acute COPD exacerbation commonly causes increased dyspnea, wheezing, sputum purulence, prolonged expiration, and hypoxemia.

Answer 2

Correct Answers:

Respiratory acidosis, partially compensated

Rationale :

🧪The pH of 7.31 indicates acidemia because it is below the expected range.

🫁The PaCO₂ of 58 mmHg identifies carbon dioxide retention as the respiratory cause of the acidemia.

🩸The elevated HCO₃⁻ of 30 mEq/L demonstrates renal compensation through bicarbonate retention.

⚖️Because the pH remains abnormal despite increased bicarbonate, the imbalance is partially compensated respiratory acidosis.

📌Core Message:

A decreased pH, elevated PaCO₂, and compensatory elevation in bicarbonate indicate partially compensated respiratory acidosis.

Answer 3

Correct Answers:

Ineffective breathing

Rationale :

🚨The client has labored respirations, accessory-muscle use, wheezing, and tachypnea, indicating impaired breathing.

📉An oxygen saturation of 86% and PaO₂ of 55 mmHg demonstrate severe oxygenation impairment.

🫁The elevated PaCO₂ and decreased pH show inadequate alveolar ventilation with carbon dioxide retention.

🎯Following airway and breathing priorities, ineffective breathing requires intervention before fluid balance or suspected infection.

📌Core Message:

Actual respiratory distress and severe hypoxemia make ineffective breathing the highest-priority problem.

Answer 4

Correct Answers:

Start empiric antibiotic therapy
Administer a short-acting bronchodilator
Administer corticosteroids intravenously

Rationale :

🦠Empiric antibiotic therapy is anticipated because fever, leukocytosis, and purulent sputum suggest a bacterial respiratory infection.

💨A short-acting bronchodilator such as albuterol rapidly decreases bronchospasm and improves airflow.

💉Systemic corticosteroids reduce airway inflammation and shorten recovery from a moderate-to-severe exacerbation.

🩺These treatments address the likely infection, bronchoconstriction, and inflammation driving the client’s acute respiratory deterioration.

📌Core Message:

Acute COPD exacerbation treatment includes short-acting bronchodilators, systemic corticosteroids, and antibiotics when bacterial infection is suspected.

Answer 5

Correct Answers:

Titrate oxygen to maintain SpO2 between 88-92%

Rationale :

🫁Controlled oxygen therapy corrects severe hypoxemia while reducing the risk of excessive oxygen administration.

🎯For clients at risk of hypercapnic respiratory failure, the usual target is an SpO₂ between 88% and 92%.

🧪Excessive oxygen can worsen carbon dioxide retention through increased ventilation-perfusion mismatch and the Haldane effect.

📊The nurse should titrate oxygen carefully and reassess the client’s mental status, respiratory effort, oxygen saturation, and ABGs.

📌Core Message:

Oxygen during an acute COPD exacerbation should be carefully titrated to maintain SpO₂ between 88% and 92%.

Answer 6

Correct Answers:

Temperature decreases from 100.6 °F to 99.5 °F
Arterial Blood Gas: pH 7.35, PaCO2 - 55, HCO, - 31
SpO2 increased from 86% to 90% on 2L nasal cannula

Rationale :

🌡️The decrease in temperature indicates improvement in the inflammatory or infectious process contributing to the exacerbation.

🧪The ABG shows a normalized pH of 7.35 and a reduction in PaCO₂ from 58 to 55 mmHg, demonstrating improved ventilation with chronic compensation.

🫁An increase in SpO₂ from 86% to 90% indicates improved oxygenation within the usual COPD target range of 88% to 92%.

📈Together, these findings demonstrate improvement in infection control, ventilation, acid-base balance, and oxygenation.

📌Core Message:

Improvement in an acute COPD exacerbation is demonstrated by a lower temperature, improved ABG values, and oxygen saturation maintained within the 88% to 92% target range.

Answer 7

Correct Answers:

Albuterol

Rationale :

💨Albuterol is a short-acting beta₂-adrenergic agonist that rapidly relaxes bronchial smooth muscle.

🚨During an acute asthma attack, the immediate priority is reversing bronchospasm and airflow obstruction.

⏱️Inhaled albuterol has a rapid onset and is considered a rescue medication.

🫁The nurse should monitor the client’s breath sounds, oxygen saturation, respiratory effort, and possible tachycardia or tremors.

📌Core Message:

An acute asthma attack requires immediate administration of a rapid-acting short-acting beta₂ agonist.

Answer 8

Correct Answers:

Previous intubation due to status asthmaticus episode

Rationale :

🚨A history of previous intubation for asthma identifies a client with prior life-threatening airway obstruction.

🫁These clients have a greater risk of developing another severe episode of status asthmaticus.

📋Previous mechanical ventilation indicates that standard rescue treatments once failed to control the client’s bronchospasm.

🔍The nurse should closely monitor such clients for decreasing breath sounds, exhaustion, altered consciousness, and worsening hypoxemia.

📌Core Message:

Previous asthma-related intubation or mechanical ventilation is a major risk factor for future status asthmaticus.

Answer 9

Correct Answers:

Suppress respiratory effort

Rationale :

💉Pancuronium is a nondepolarizing neuromuscular-blocking medication that causes skeletal-muscle paralysis.

🫁It suppresses spontaneous respiratory muscle activity, allowing the ventilator to control breathing effectively.

⚙️The medication can improve ventilator synchrony when respiratory effort interferes with prescribed ventilation.

⚠️Because pancuronium does not provide sedation or analgesia, the client must also receive adequate sedation and pain control.

📌Core Message:

Pancuronium suppresses spontaneous respiratory effort to promote synchrony with mechanical ventilation.

Answer 10

Correct Answers:

Sepsis

Rationale :

🦠Sepsis is the most common precipitating cause of acute respiratory distress syndrome.

🔥The systemic inflammatory response increases pulmonary capillary permeability.

💧Protein-rich fluid subsequently enters the alveoli, producing noncardiogenic pulmonary edema.

📉The resulting alveolar collapse and shunting cause severe refractory hypoxemia and reduced lung compliance.

📌Core Message:

Sepsis is the most common cause of ARDS because systemic inflammation damages the alveolar-capillary membrane.
