What is the desired peripheral capillary oxygen saturation (Spo2) level in the patient with chronic obstructive pulmonary disease?

92% to 95%

85% to 88%

95% to 100%

88% to 92%

Answer and Explanation

The Correct Answer is A

A. This range is generally considered acceptable for most patients with COPD. It provides a balance between ensuring adequate oxygenation while avoiding the risk of oxygen toxicity. Oxygen saturation levels within this range can help alleviate symptoms of hypoxemia without causing hyperoxia.
B. Oxygen saturation levels below 90% can lead to significant hypoxemia and exacerbate respiratory distress in individuals with COPD. Maintaining oxygen saturation levels above 90% is typically recommended to prevent complications associated with hypoxemia.
C. This range is appropriate for some patients but it may not be ideal for all patients with COPD. Oxygen saturation levels at the higher end of this range (e.g., 100%) can increase the risk of oxygen toxicity in patients with COPD who retain carbon dioxide (CO2) due to their chronic respiratory condition.
D. Oxygen saturation levels within this range help to balance the need for oxygen supplementation with the risk of hyperoxia and oxygen toxicity. However, individual patient factors, such as the severity of COPD, baseline oxygen saturation levels, and comorbidities, should be considered when determining the target range for oxygen saturation.

Correct Answer is A

Explanation

A. Sucralfate works by forming a protective barrier over the ulcer site. It adheres to the ulcer, shielding it from the harmful effects of gastric acid, pepsin, and bile salts. This protection allows the ulcer to heal by preventing further irritation and damage.
B. Medications that prevent gastric acid secretion are typically proton pump inhibitors (PPIs) or H2 receptor antagonists. Sucralfate does not reduce or inhibit the production of gastric acid; instead, it protects the ulcer from the acid already present.
C. Antacids are the type of medication that neutralize gastric acid. Sucralfate does not neutralize acid; it acts locally at the ulcer site to create a protective coating.
D. Antibiotics are used to kill Helicobacter pylori, the bacteria often responsible for causing peptic ulcers. Sucralfate does not have antibacterial properties and does not target or eliminate bacteria.

A. teach the patient the use of accessory muscles B. ask the patient what caused the dyspnea C. encourage the use of pursed lip breathing D. assist the patient into a Sims position

Correct Answer is C

Explanation

C. Pursed lip breathing is a technique that can help patients with acute dyspnea by improving ventilation, prolonging exhalation, and reducing the work of breathing. It helps to keep the airways open longer and makes it easier to get rid of excess carbon dioxide, which can provide quick relief from acute shortness of breath.
A. Teaching the patient about using accessory muscles for breathing can be beneficial in managing chronic respiratory issues, but it is not an immediate intervention.
B. Understanding the cause of dyspnea is important for treatment planning but it is not the first action to take when the patient is experiencing acute shortness of breath.
D. The Sims position, where the patient lies on their side with the lower arm behind the back and the upper leg flexed, is not typically used for relieving acute respiratory distress.
