Correct Answer: D

Rationale: The correct answer is D: 'Redness, swelling, and warmth at the surgical site.' These are specific signs of infection at the surgical site that a nurse should monitor for in a postoperative patient. While fever, chills, and increased pain can also indicate infection, the most direct signs are redness, swelling, and warmth at the surgical site. Therefore, 'D' is the best choice as it directly relates to the site of the surgery and is crucial to monitor for potential postoperative infections.

Correct Answer: B

Rationale: The correct answer is B because chest physiotherapy (CPT) helps reduce respiratory infections by loosening mucus in the lungs. Choice A is incorrect because coughing may temporarily increase during CPT treatments as mucus is being cleared. Choice C is incorrect because postural drainage is typically performed before meals. Choice D is incorrect because while CPT can help manage symptoms and improve lung function in COPD, it does not cure the disease.

Correct Answer: C

Rationale: The correct action for the nurse to take is to contact the provider for prescription clarification. Administering vancomycin over less than 60 minutes can lead to infusion reactions like hypotension and flushing. Starting the infusion immediately (choice A) is incorrect as it goes against the prescribed rate. Slowing down the infusion rate (choice B) without provider approval can result in underdosing the medication. Checking blood pressure during the infusion (choice D) is important but not the most immediate action needed in this situation.

Correct Answer: A

Rationale: The correct answer is to store the current bottle of insulin at room temperature. Insulin should be stored this way to maintain its potency and effectiveness. Choice B is incorrect because massaging the injection site after removing the needle is not recommended practice and can cause bruising. Choice C is incorrect as pulling back on the plunger after injecting insulin can lead to injecting air bubbles into the tissue. Choice D is incorrect as syringes should not be reused multiple times due to the risk of contamination and inaccurate dosing.

Correct Answer: D

Rationale: The correct answer is D because measuring hourly urinary output is a task that falls within the scope of practice for assistive personnel. This task involves a technical skill that can be delegated by the charge nurse. Choices A, B, and C require higher-level nursing assessments and interventions that should be performed by licensed nursing staff. Giving a glycerin suppository involves medication administration, evaluating the effectiveness of ibuprofen requires assessment and critical thinking, and discussing dietary changes involves education and assessment of the client's understanding and compliance, all of which are beyond the scope of practice for assistive personnel.
