Correct Answer: C

Rationale: The correct answer is C: Disruption of tissue integrity. Acute pain is typically caused by tissue damage or injury, such as a cut or a burn. The nurse would use this assessment data as an etiology for acute pain because it directly relates to the source of the pain. Discomfort while changing position (A) is a symptom of pain but does not provide the underlying cause. Reports pain as a 7 on a 0 to 10 scale (B) is a pain intensity rating and does not explain the cause of the pain. Dull headache (D) is a specific type of pain but is not relevant to the given scenario of tissue disruption.

Correct Answer: C

Rationale: The correct answer is C because it does not provide a specific, measurable outcome. It is vague and subjective, making it difficult to assess and track progress. In contrast, choices A, B, and D are all specific, measurable, and time-bound goals, making them more effective for evaluating client outcomes. Choice A specifies the amount of fluid intake and the time frame, choice B sets a clear deadline for demonstrating a skill, and choice D outlines a specific task to be completed upon discharge. Therefore, C is the correct answer as it lacks the clear criteria needed for effective outcome evaluation.

Correct Answer: D

Rationale: The correct answer is D: Improve ability to hear. A hearing aid is designed to improve a person's ability to hear by amplifying sound. This helps individuals with hearing loss to better understand speech and sounds in their environment. A: Amplifying background noise is not the main purpose of a hearing aid. It may actually hinder the user's ability to focus on important sounds. B: Amplifying musical sounds is not the primary function of a hearing aid. The main focus is on improving speech understanding. C: Occluding the ear is not the purpose of a hearing aid. It is meant to enhance hearing, not block sound.

Correct Answer: A

Rationale: The correct answer is A: Preventing infection. With a low WBC count of 3,000/ul, the client is at high risk for infection due to compromised immune function. Priority is to prevent infection by implementing strict infection control measures, such as hand hygiene, sterile techniques, and isolation precautions. Alleviating pain (B) would be important but not the priority in this case. Controlling infection (C) is similar to preventing infection and would be a secondary intervention. Monitoring blood transfusion reactions (D) is not relevant to the client's current lab values.

Correct Answer: A

Rationale: The correct answer is A because observing the patient for abnormal bleeding is an appropriate action to monitor for potential complications of warfarin therapy. This aligns with the nursing role in assessing and monitoring patient responses to treatment. B is incorrect as increasing warfarin dose without physician order can lead to adverse effects. C is incorrect as altering the dose without medical advice can be dangerous. D is incorrect as administering Vitamin K would counteract the effects of warfarin, which is used to prevent blood clotting.
