A patient has a diagnosis of Impaired Gas Exchange. Which assessment finding shows that the interventions have been effective?
The patient's Spo2 is 97% on 2L NC
The patient appears comfortable
The patient is coughing up copious white sputum
The patient is able to move out of bed without difficulty
The Correct Answer is A
A. The patient's Spo2 is 97% on 2L NC:
This assessment finding indicates that the patient's oxygen saturation level (SpO2) is 97% while receiving 2 liters per minute of oxygen via nasal cannula. Oxygen saturation is a measure of the percentage of hemoglobin saturated with oxygen in the blood. A SpO2 level of 97% suggests adequate oxygenation, which is essential for effective gas exchange. Therefore, if the patient's SpO2 is within the target range on the prescribed oxygen therapy, it indicates that the interventions aimed at improving gas exchange have been effective.
B. The patient appears comfortable:
While patient comfort is important, it is not a direct indicator of effective gas exchange. A patient may appear comfortable for various reasons, such as pain relief, proper positioning, or emotional support, but this does not necessarily reflect improved gas exchange. Therefore, while comfort is an important aspect of nursing care, it is not specifically indicative of the effectiveness of interventions for impaired gas exchange.
C. The patient is coughing up copious white sputum:
The presence of copious white sputum does not directly indicate improved gas exchange. White sputum may suggest various conditions, such as respiratory tract infections or inflammation, but it does not provide direct information about gas exchange efficiency. Effective gas exchange involves the exchange of oxygen and carbon dioxide at the alveolar-capillary membrane, which cannot be assessed solely based on sputum production.
D. The patient is able to move out of bed without difficulty:
The ability to move out of bed without difficulty may indicate improved overall physical function or mobility, but it does not specifically reflect improved gas exchange. Gas exchange primarily involves the transfer of oxygen from the alveoli into the bloodstream and the removal of carbon dioxide from the bloodstream into the alveoli for exhalation. While improved gas exchange may lead to enhanced physical endurance and reduced dyspnea, the ability to move out of bed without difficulty is not a direct measure of gas exchange efficiency.

Correct Answer is B
Explanation
A. Add tap water as needed to the suction control chamber.
This is not the correct action. The suction control chamber of a water-seal chest tube drainage system is typically filled with sterile water to the prescribed level by the healthcare provider during the initial setup. Adding tap water to the suction control chamber can disrupt the balance of the system and affect the prescribed suction level. The nurse should not add tap water without specific instructions from the healthcare provider.
B. Maintain the drainage container below the level of the client's chest.
This is the correct action. In a water-seal chest tube drainage system, it's important to keep the drainage container below the level of the client's chest. This positioning allows gravity to assist in the drainage of air or fluid from the pleural space into the drainage container. It also helps prevent backflow of fluid or air into the chest cavity, ensuring the effectiveness of the drainage system.
C. Empty the collection container every shift.
While it may be necessary to empty the collection container if it becomes full, emptying it every shift is not a set rule. The frequency of emptying the collection container should be based on the volume of drainage and the facility's policy. The nurse should monitor the collection container regularly and empty it when it reaches the appropriate level, typically around half full or as indicated by facility protocol.
D. Clamp the chest tubes if it becomes disconnected.
Clamping the chest tubes if they become disconnected is not recommended. It can lead to tension pneumothorax, a life-threatening condition where air accumulates in the pleural space and compresses the lung. If a chest tube becomes disconnected, the nurse should immediately assess the situation, secure the chest tube connections, and notify the healthcare provider for further management.
Correct Answer is C
Explanation
A. Constipation
Constipation is not typically associated with obstructive sleep apnea. However, sleep disturbances and certain medications used to manage OSA may indirectly contribute to constipation in some cases.
B. Nausea
Nausea is not a common symptom of obstructive sleep apnea. While sleep disturbances may affect gastrointestinal function in some individuals, nausea is not a typical manifestation of OSA.
C. Headache
One of the common findings associated with obstructive sleep apnea (OSA) is headache. This occurs due to the repeated episodes of apnea (cessation of breathing) during sleep, which leads to intermittent hypoxia (low oxygen levels) and subsequent cerebral vasodilation. The vasodilation can trigger headaches, often described as morning headaches, upon waking up. These headaches are typically frontal and may be accompanied by other symptoms such as fatigue and irritability.
D. Hypotension
Hypotension (low blood pressure) is not a typical finding in obstructive sleep apnea. In fact, individuals with OSA are more likely to have hypertension (high blood pressure) due to the effects of repeated apnea episodes on the cardiovascular system, such as increased sympathetic activity and arterial stiffness.
