Which of the following does the nurse implement to prevent postoperative respiratory complications for a patient? (Select all that apply)

Choice A reason: Signal anxiety refers to a specific concern or perceived threat, which is not indicated by the patient's statement.

Choice B reason: Severe anxiety is a high level of anxiety that would likely impair functioning, which cannot be determined from the patient's statement alone.

Choice C reason: Moderate anxiety is a manageable level of anxiety, but the patient's statement suggests a more pervasive and non-specific anxiety.

Choice D reason: Free-floating anxiety is a general feeling of dread or foreboding that is not attached to any specific issue or situation, which aligns with the patient's expression of a vague sense of impending doom.

Choice A reason: While limit-setting is important, it should not be overly strict as it can increase anxiety in patients who are already highly anxious.

Choice B reason: Increasing environmental stimuli may overwhelm a highly anxious patient rather than help them.

Choice C reason: Providing support and a therapeutic milieu offers a safe and structured environment, which can help reduce anxiety and promote healing.

Choice D reason: More freedom can be beneficial, but it must be balanced with the need for a supportive and structured environment for a highly anxious patient.
