A venturi mask: The Venturi mask is often used in patients with COPD. However, it may cause dryness and irritation in the nasal passages and sinuses due to non-humidified, high-flow delivery, which could aggravate existing sinus conditions.

A nasal cannula: While nasal cannulas are less drying than masks and suitable for low-flow oxygen delivery, they can still cause mucosal dryness when used without humidification, particularly in patients with sinus issues.

High-flow oxygen via nasal cannula: High-flow nasal cannula therapy provides warmed, humidified oxygen, but at higher rates than needed for most patients starting oxygen therapy. It is more appropriate for acute respiratory failure than for routine use in sinus conditions.

Adding humidification to the oxygen setup: Humidifying oxygen helps prevent nasal and sinus mucosal dryness and irritation, making it beneficial for patients with sinus disorders. Moisture improves comfort and protects the integrity of the upper airway mucosa during oxygen therapy.

Respiratory rate may be increased a great part of the time: While some clients with emphysema may exhibit tachypnea during exertion or exacerbations, this is not a consistent or defining characteristic across all situations.

Lung stretch receptors may fail to monitor the patterns of breathing: Lung stretch receptors play a role in the Hering-Breuer reflex, but there is no evidence that they fail to function in emphysema. The issue in emphysema is gas trapping and reduced surface area for gas exchange, not receptor failure.

Intercostal muscles contract during inspiration, but fail to relax during expiration: The intercostal muscles assist with ventilation, particularly during increased respiratory effort. However, their relaxation in expiration is typically passive and not impaired in emphysema.

"It will reduce the frequency of your cough. Antitussives suppress the cough reflex and may reduce how often the patient coughs. However, this answer is vague and does not address the patient's concern and doesn't provide specific guidance on usage.

"It should be used in the morning." Antitussives are not recommended for use in the morning unless the cough is disruptive to daytime function. Taking them in the morning could lead to daytime drowsiness, if the medication contains sedating agents like codeine.

"It will eliminate your cough at night." While antitussives may greatly reduce coughing, they do not guarantee total elimination of the cough. This statement creates unrealistic expectations and may mislead the patient regarding the effectiveness of the medication.

"I have cared for patients who were able to have the tracheostomy reversed. While this may offer hope, it shifts the focus to long-term outcomes rather than addressing the patient's current emotional state. Not all tracheostomies are reversible, and offering this reassurance prematurely may set unrealistic expectations.

“I will be efficient and give care quickly." Although efficiency is important, this response may come off as dismissive of the patient's emotional needs. It prioritizes task completion over patient-centered care and fails to address the underlying anxiety.

"I will wait until your tracheostomy heals before teaching." Teaching should begin early, even in small steps, to help the patient gradually understand and adapt to tracheostomy care. Delaying education may increase fear, uncertainty, and dependence on others for care.

Initiate and maintain supplemental oxygen as prescribed: Supplemental oxygen helps improve oxygenation but does not directly address the underlying issue of retained secretions. Oxygen delivery is important, but secretion removal is the priority when the airway is obstructed.

Plan activities with rest periods to conserve oxygen needs: While energy conservation is useful for managing oxygen demand in alert clients, it does not apply to an unresponsive client. Additionally, it does not assist with clearing the airway or managing retained secretions.

Monitor oxygenation (the oxygen saturation [SaO2]) during activity: Monitoring oxygen saturation is helpful for evaluating respiratory status, but this intervention does not address the immediate problem of retained secretions compromising airway clearance.

Chest x-ray: A chest x-ray can show lung abnormalities consistent with TB, such as cavitations or infiltrates, but it cannot confirm active infection. It is useful for supporting diagnosis but must be interpreted alongside microbiological tests.

Mantoux test: The Mantoux (PPD) test identifies TB exposure by measuring delayed hypersensitivity, but it does not distinguish between latent and active infection. A positive result requires further testing to confirm active disease.

Pulmonary function test: Pulmonary function tests assess lung capacity and airflow but are not used for diagnosing tuberculosis. They may be used later to evaluate lung impairment but have no role in confirming TB.

“I will rest my hand over my abdomen to create resistance.” This technique is used for diaphragmatic breathing exercises, not incentive spirometry. It does not help assess or improve lung expansion, which is the primary goal of using the incentive spirometer.

“I will lie on my back with my knees bent.” While lying down may be appropriate for some breathing exercises, the incentive spirometer is best used in a sitting or upright position. Sitting allows for maximal lung expansion and facilitates more effective use of the device.

“I will place the adapter on my finger to read my blood oxygen saturation level.” This describes the use of a pulse oximeter, not an incentive spirometer. The spirometer measures inspiratory volume, while pulse oximetry is used to monitor oxygen saturation.

Barrel chest and polycythemia: These findings are more characteristic of chronic obstructive pulmonary disease, especially emphysema. They reflect long-term adaptations to hypoxia and air trapping, not the acute onset seen in pneumothorax.

Bronchovesicular lung sounds and bradypnea: Bronchovesicular sounds are normal in some lung areas, and bradypnea is not a common feature of pneumothorax. Pneumothorax often presents with decreased or absent breath sounds on the affected side and increased respiratory rate due to hypoxia.

Frothy bloody sputum and consolidation: These findings suggest pulmonary edema or pneumonia rather than pneumothorax. Frothy sputum is often seen in left-sided heart failure, and lung consolidation is not a feature of air in the pleural space.
