A patient with COPD would be expected to have

loss of protective respiratory mechanisms due to prolonged irritation or damage.

localized swelling and Inflammation within the lungs.

an acute viral Infection of the respiratory tract.

inflammation and swelling of the sinus membranes over a prolonged period.

Answer and Explanation

The Correct Answer is A

A) Loss of protective respiratory mechanisms due to prolonged irritation or damage:
Individuals with COPD often experience a progressive loss of protective respiratory mechanisms over time. Chronic exposure to irritants such as cigarette smoke leads to inflammation, structural changes in the airways, and destruction of lung tissue, impairing the body's ability to clear mucus, trap foreign particles, and maintain normal lung function. This loss of protective mechanisms contributes to the hallmark symptoms of COPD, including airflow limitation, chronic cough, and increased susceptibility to respiratory infections.

B) Localized swelling and inflammation within the lungs:
While inflammation is a hallmark feature of COPD, it typically manifests as widespread inflammation throughout the lungs rather than localized swelling. In COPD, chronic exposure to irritants leads to a systemic inflammatory response that affects the entire respiratory tract, including the bronchi and alveoli. This inflammation contributes to airway obstruction, mucus hypersecretion, and the development of respiratory symptoms.

C) An acute viral infection of the respiratory tract:
While individuals with COPD are at increased risk of respiratory infections, including viral infections such as influenza and respiratory syncytial virus (RSV), COPD itself is a chronic, progressive respiratory condition characterized by persistent airflow limitation. Acute viral infections may exacerbate COPD symptoms and lead to worsening respiratory function, but they are not inherent features of the disease itself.

D) Inflammation and swelling of the sinus membranes over a prolonged period:
Sinus inflammation and swelling, known as sinusitis, are not typically considered primary features of COPD. While individuals with COPD may experience comorbid conditions such as chronic rhinosinusitis, which can contribute to respiratory symptoms and exacerbations, sinus inflammation is not a defining characteristic of the disease.

Correct Answer is A

Explanation

A) Hypoxemia:
This is the correct answer. Atelectasis, which is the collapse or incomplete inflation of the lung, can lead to impaired gas exchange and subsequent hypoxemia. As lung volume decreases due to collapse, ventilation-perfusion (V/Q) mismatch occurs, resulting in decreased oxygenation of arterial blood. Hypoxemia is a common finding in individuals with atelectasis and may manifest as decreased oxygen saturation levels on pulse oximetry or arterial blood gas analysis.

B) Apnea:
Apnea, defined as the cessation of breathing, is not typically associated with atelectasis. While atelectasis can contribute to respiratory compromise and may result in respiratory distress, including tachypnea or increased work of breathing, it does not usually lead to complete cessation of breathing.

C) Pleural effusion:
A pleural effusion is the accumulation of fluid in the pleural space surrounding the lungs. While pleural effusion may occur concurrently with atelectasis, it is not an expected finding specifically associated with atelectasis itself. Pleural effusion may cause respiratory symptoms such as dyspnea or chest pain but is not a primary manifestation of atelectasis.

D) Dysphagia:
Dysphagia, or difficulty swallowing, is unrelated to atelectasis. While dysphagia can occur as a result of various conditions affecting the esophagus or neurological control of swallowing, it is not a typical manifestation of atelectasis. Atelectasis primarily affects the lungs and respiratory function rather than swallowing function.

A. Respiratory rate 18/min B. Oxygen saturation 95% C. Heart rate 46/min D. Blood pressure 160/94 mm Hg

Correct Answer is C

Explanation

A) Respiratory rate 18/min:
A respiratory rate of 18/min is within the normal range for adults and is not a contraindication for administering atenolol. This finding does not warrant withholding the medication.

B) Oxygen saturation 95%:
An oxygen saturation of 95% is within the normal range and does not indicate any acute respiratory compromise. It is not a contraindication for administering atenolol.

C) Heart rate 46/min:
A heart rate of 46/min is below the normal range (typically 60-100 beats per minute for adults). Atenolol is a beta-blocker that primarily acts to reduce heart rate and blood pressure. Administering atenolol to a client with bradycardia (heart rate less than 60/min) can further decrease heart rate and may lead to symptomatic bradycardia or heart block. Therefore, the nurse should withhold atenolol in this case and notify the healthcare provider.

D) Blood pressure 160/94 mm Hg:
A blood pressure of 160/94 mm Hg indicates hypertension (elevated blood pressure). While atenolol is often prescribed for the management of hypertension, this blood pressure reading alone does not warrant withholding the medication. However, the client's bradycardia (heart rate 46/min)’is a more immediate concern that requires action."
