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 A
Explanation
A. Withhold food and liquids until the client's gag reflex returns.
This is the correct action. After a bronchoscopy, the client's throat may be numb or irritated from the procedure, which can temporarily impair the gag reflex. Withholding food and liquids until the gag reflex returns reduces the risk of aspiration, where food or liquid enters the airway instead of the stomach. Aspiration can lead to pneumonia and other serious complications. Therefore, it's essential to assess the client's gag reflex before allowing them to eat or drink.
B. Irrigate the client's throat every 4 hours.
This action is not necessary and may even be harmful. Irrigating the client's throat every 4 hours could further irritate the throat and increase discomfort for the client. Unless specifically ordered by the healthcare provider for a specific reason, such as to remove secretions or debris, routine irrigation of the throat is not recommended after a bronchoscopy.
C. Have the client refrain from talking for 24 hours.
There is typically no need for the client to refrain from talking for 24 hours after a bronchoscopy. While the client may experience some throat discomfort and hoarseness, restricting talking for such an extended period is unnecessary and may cause undue stress or anxiety for the client. Unless specifically instructed by the healthcare provider for a valid reason, such as to allow vocal cord healing, there is no need to restrict talking for such a long duration.
D. Suction the client's oropharynx frequently.
Frequent suctioning of the client's oropharynx is not indicated unless there is a specific medical reason to do so. Excessive suctioning can cause trauma to the mucous membranes, increase the risk of infection, and exacerbate throat irritation. The decision to suction should be based on clinical assessment, such as evidence of secretions or if the client is having difficulty clearing their airway, rather than being performed routinely.
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.
