Correct Answer: D

Rationale: The correct answer is D: Decrease the respiratory rate. The ABG results show respiratory alkalosis with decreased PaCO2 and elevated pH. This indicates overventilation, so decreasing the respiratory rate will help normalize the PaCO2 and pH levels. Increasing the FIO2 (Choice A) is not needed as the PaO2 is within normal range. Increasing tidal volume (Choice B) can lead to further hyperventilation. Increasing the respiratory rate (Choice C) would exacerbate the respiratory alkalosis.

Correct Answer: C

Rationale: Step-by-step rationale for choice C: 1. Activity intolerance is a priority nursing problem postoperatively due to pain. 2. Postoperative pain can limit the client's ability to perform activities. 3. Addressing activity intolerance is crucial for promoting recovery and preventing complications. 4. Delaying the teaching session helps the nurse focus on managing pain first. Summary of why other choices are incorrect: - Choice A: Knowledge deficit can be addressed after managing immediate postoperative issues. - Choice B: Treatment regimen management is important but may not be as urgent as addressing activity intolerance related to pain. - Choice D: Noncompliance with exercise plan can be addressed once the client's pain and activity intolerance are under control.

Correct Answer: C

Rationale: The correct answer is C because BIS and PSI monitors provide both raw EEG data and a numeric value, simplifying the interpretation of patient sedation levels. Raw EEG data offers detailed information on brain activity, while the numeric value allows for quick assessment. This simplifies the monitoring process compared to interpreting raw EEG data alone. Choice A is incorrect as BIS and PSI monitors are not restricted to heavily sedated patients. Choice B is incorrect as they are not limited to pediatric patients. Choice D is incorrect as the number of leads required does not determine the simplicity of use; it is the data interpretation that matters.

Correct Answer: A

Rationale: The correct answer is A: Airway clearance therapies. In cystic fibrosis (CF), mucus buildup in the lungs can lead to infections and breathing difficulties. Airway clearance therapies help loosen and clear this mucus, improving lung function. Antibiotic therapy (B) is used to treat infections but is not specific to CF treatment. Nutritional support (C) is crucial in CF due to malabsorption, but it is not the primary treatment. Tracheostomy (D) is a surgical procedure to create an airway bypassing the upper respiratory tract and is not a standard treatment for CF.

Correct Answer: D

Rationale: The correct answer is D, The Joint Commission, because it is a regulatory body that accredits healthcare organizations and requires them to have mechanisms for addressing ethical issues to ensure patient safety and quality of care. The other choices (A, B, C) are professional organizations that focus on specific areas of healthcare practice and do not have the authority to set regulatory standards for addressing ethical issues in healthcare organizations.
