ATI PN Comprehensive Predictor 2024

Correct Answer: C

Rationale: The correct answer is 0.9% sodium chloride. This solution is isotonic and helps maintain electrolyte balance during irrigation, preventing fluid and electrolyte imbalances. Tap water (choice A) may cause electrolyte imbalances due to its hypotonic nature. Sterile water (choice B) is hypotonic and can lead to electrolyte disturbances. 0.45% sodium chloride (choice D) is hypotonic and may also disrupt electrolyte balance when used for irrigation.

Correct Answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting clients with C. difficile is crucial to prevent the transmission of the infection. Options A, B, and C are incorrect because assigning the client to a room with a negative air-flow system, using alcohol-based hand sanitizer, and cleaning contaminated surfaces with a phenol solution are not specific measures for preventing the spread of C. difficile.

Correct Answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.

Correct Answer: B

Rationale: The correct next step when a client develops phlebitis while receiving IV fluids is to remove the catheter and place it in another site. Phlebitis is inflammation of a vein, and leaving the catheter in the same site can lead to further complications. Monitoring the site for further swelling, as in choice A, is not enough as the source of inflammation needs to be removed. Choice C, reducing the flow rate, may not address the underlying issue causing phlebitis. Switching to oral hydration, as in choice D, is not necessary for addressing phlebitis related to IV fluid administration.

Correct Answer: A

Rationale: The correct answer is A: Shortness of breath and weight gain. Early signs of heart failure typically manifest as shortness of breath due to fluid accumulation in the lungs and weight gain due to fluid retention in the body. Choices B, C, and D are incorrect. Fatigue and chest pain are symptoms commonly associated with heart conditions but are not specific early signs of heart failure. Nausea and vomiting are not typically early signs of heart failure. Cough can be a symptom of heart failure, but it is usually associated with other symptoms like shortness of breath rather than being an isolated early sign. Elevated blood pressure is not an early sign of heart failure; in fact, heart failure is more commonly associated with low blood pressure.
