Correct Answer: B

Rationale: The correct first action when irrigating a wound is to cleanse the wound from the center outward. This method helps remove debris and pathogens effectively, reducing the risk of infection. Choice A is incorrect because wearing sterile gloves should be done before starting the wound irrigation but is not the first action in the process. Choice C is incorrect as applying a warm compress is not the initial step in wound irrigation. Choice D is also incorrect as using a syringe to irrigate the wound comes after cleansing the wound.

Correct Answer: C

Rationale: Placing a pillow between the client's legs is beneficial after hip replacement surgery to maintain proper alignment and prevent dislocation of the prosthesis. This position helps keep the hip in a neutral position, reducing the risk of dislocation. Encouraging the client to bend at the waist (Choice A) can increase the risk of hip dislocation. Maintaining the client in a high-Fowler's position (Choice B) and avoiding placing a pillow under the client's knees (Choice D) do not directly address the need to maintain proper alignment of the hip joint to prevent dislocation.

Correct Answer: B

Rationale: The correct answer is B because imagining oneself in a calm place is a relaxation technique that helps reduce anxiety. Walking, meditating every other week, or cutting back on caffeine intake may have their benefits, but they are not as directly related to the immediate management of anxiety as the visualization technique described in option B.

Correct Answer: A

Rationale: Low birth weight increases a child's vulnerability to physical maltreatment due to additional care needs. Advanced maternal age (choice B) is not directly linked to an increased risk of physical maltreatment. Single parenthood (choice C) is not a characteristic that inherently increases the risk of physical maltreatment. Premature birth (choice D) is not listed as a characteristic that directly increases a child's risk of physical maltreatment.

Correct Answer: A

Rationale: The correct answer is A. New confusion in a client with pneumonia could indicate hypoxia or a worsening condition, requiring immediate attention. Option B, a client with diabetes having low blood sugar overnight, is a concerning condition but not as urgent as potential hypoxia. Option C, a client with a leg fracture needing pain medication, and option D, a client with decreased urinary output, are important but do not take precedence over addressing a potentially critical respiratory issue.
