PN ATI Comprehensive Predictor

Correct Answer: A

Rationale: The correct technique for administering an intramuscular (IM) injection is to locate the injection site and insert the needle at a 90-degree angle. This angle ensures that the medication is delivered into the muscle for proper absorption. Choice B is incorrect because a 45-degree angle is typically used for subcutaneous injections, not intramuscular. Choice C is incorrect as massaging the site after an injection can cause the medication to disperse unevenly. Choice D is incorrect as a 15-degree angle would not reach the muscle layer effectively for an IM injection.

Correct Answer: B

Rationale: The correct answer is to check for air leaks and ensure the chest tube is functioning properly. This is crucial post-surgery to prevent complications such as pneumothorax or hemothorax. Clamping the chest tube, positioning the client, or encouraging coughing are not appropriate assessments for a client with a chest tube post-surgery and could lead to serious issues if done incorrectly.

Correct Answer: A

Rationale: The correct answer is A: Maintain sterility during dressing changes. It is crucial to maintain sterility during dressing changes for patients with central venous catheters to prevent infections. Changing the dressing weekly (Choice B) is not frequent enough to prevent infections effectively. Monitoring blood pressure and fluid balance (Choice C) is important for overall patient care but not specific to central venous catheter management. While monitoring the catheter site for infection (Choice D) is important, the key consideration is to prevent infections through proper sterile techniques during dressing changes.

Correct Answer: B

Rationale: The correct answer is B: Ensure that oxygen tanks are kept upright and away from heat sources. This is the most important safety measure to prevent accidents related to home oxygen use. Storing oxygen tanks in a closet when not in use (choice A) is not recommended as they should be stored in a well-ventilated area. Allowing family members to smoke in designated areas (choice C) poses a significant fire hazard. Restricting fluid intake while using oxygen (choice D) is not a safety measure related to oxygen use.

Correct Answer: D

Rationale: Administering analgesics on a scheduled basis for the first 24 hours is crucial to ensure adequate pain control in the immediate postoperative period. Choice A is incorrect because clear liquids are typically initiated gradually and advanced as tolerated but not specifically at 6 hours post-surgery. Choice B is incorrect as cromolyn nebulizer solution is not indicated for postoperative pain management in this scenario. Choice C is incorrect as applying a warm compress may not be appropriate for the operative site after appendicitis surgery and can potentially increase the risk of infection.
