Question 1 of 5

Noise in the critical care unit can have negative effects on the patient. Which of the following interventions assists in reducing noise levels in the criticala cbiarbr.ec osme/ttetisnt g? (Select all that apply.)

Correct Answer: A

Rationale: Step 1: Bringing in the patient's i-Pod with favorite music can provide personalized, soothing sounds, reducing stress and anxiety for the patient. Step 2: Familiar music can create a calming environment, distracting the patient from external noise. Step 3: Listening to music may improve patient comfort and overall experience in the critical care unit. Summary: Option A is correct as it directly addresses noise reduction by providing a personalized, calming environment for the patient. Options B, C, and D do not specifically target noise reduction but focus on other aspects of care or facility improvement.

Question 2 of 5

The family is considering withdrawing life-sustaining measures from the patient. The nurse knows that ethical principles for withholding or withdrawi ng life-sustaining treatments include which of the following?

Correct Answer: A

Rationale: The correct answer is A because it aligns with the ethical principle of patient autonomy, which emphasizes the patient's right to make decisions about their own care. Withholding or withdrawing life-sustaining treatments, including nutrition, antibiotics, and blood products, respects the patient's autonomy. This choice also reflects the principle of beneficence, as it aims to prevent unnecessary suffering and respects the patient's wishes. Option B is incorrect because it focuses on pain and anxiety management rather than the broader ethical considerations of withholding life-sustaining treatments. Option C is incorrect because withdrawing life-sustaining treatments while a patient is receiving paralytic agents can pose additional risks and complications, potentially conflicting with the principles of nonmaleficence and beneficence. Option D is incorrect because the primary goal of withdrawing or withholding treatments is not to hasten death but to respect the patient's autonomy and quality of life. This choice does not align with the ethical principles of patient-centered care.

Question 3 of 5

The nurse plans a teaching session with a client but postpones the planned session based on which nursing problem?

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.

Question 5 of 5

Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patient�s arterial blood gas (ABG) results include a pH of 7.51, PaO2 of 82 mm Hg, PaCO2 of 26 mm Hg, and HCO3 of 23 mEq/L (23 mmol/L). The nurse will anticipate the need to:

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.
