The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding indicates the need for immediate intervention?

Correct Answer: C

Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.

Correct Answer: B

Rationale: Confusion and altered mental status are the most critical assessment findings in a client with cirrhosis. These symptoms may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Yellowing of the skin (jaundice) is a common manifestation of cirrhosis and does not necessitate immediate intervention. Peripheral edema and increased abdominal girth are associated with fluid retention in cirrhosis but are not as urgent as addressing altered mental status and confusion.

Correct Answer: D

Rationale: Mucous plugging of the tracheostomy tube is the most concerning finding in a client with a tracheostomy and thick secretions. This can lead to airway obstruction, which requires immediate intervention to maintain a patent airway. Crepitus around the tracheostomy site may indicate subcutaneous emphysema but does not pose an immediate threat to the airway. A dry and cracked tracheostomy site may require interventions to promote healing but is not as urgent as mucous plugging. Yellowing of the skin around the tracheostomy site could indicate infection or impaired circulation, which should be addressed but does not pose the same immediate risk as airway obstruction.

Correct Answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD receiving supplemental oxygen, the use of accessory muscles is a critical finding that requires immediate intervention. This observation indicates increased work of breathing, suggesting respiratory distress. Addressing this issue promptly is crucial to prevent further respiratory compromise. Choice A, oxygen saturation of 90%, is slightly below the normal range but may not require immediate intervention unless it continues to decrease. Choice B, a respiratory rate of 24 breaths per minute, is within normal limits for an adult and does not indicate an urgent issue. Choice D, inspiratory crackles, may be present in COPD due to secretions or inflammation but do not necessitate immediate intervention unless associated with other concerning signs.

Correct Answer: C

Rationale: The correct answer is C. The use of accessory muscles is most concerning in a client with COPD receiving supplemental oxygen as it indicates increased work of breathing, requiring immediate intervention. Oxygen saturation of 90% is acceptable in a client with COPD. A respiratory rate of 24 breaths per minute is slightly elevated but not as critical as the use of accessory muscles. Inspiratory crackles may be present in clients with COPD due to underlying lung changes but do not require immediate intervention unless associated with other concerning symptoms.
