Choice A is correct as the statement indicates understanding of the chickenpox transmission timeline. Choice B is also correct as high folic acid foods are beneficial during pregnancy. Choice D is correct as washing hands with hot water after gardening helps prevent infections.

Correct Answer: C

Rationale: The correct first action for the nurse to take after realizing that the wrong medication has been administered to a client is to monitor vital signs. Monitoring vital signs is crucial as it allows the nurse to promptly assess for any immediate adverse effects that may result from the wrong medication. This immediate assessment is essential for ensuring the client's safety and well-being. Notifying the provider (choice A) and reporting the incident to the nurse manager (choice B) are important steps to take, but they should come after ensuring the client's immediate safety. Filling out an incident report (choice D) is also necessary but should be done after addressing the client's immediate needs.

Correct Answer: D

Rationale: The correct answer is D. After cataract surgery, wearing an eye shield at night for 2 weeks is essential to protect the eye during the initial healing period. Choice A is incorrect because significant eye pain should not be expected for the first 2 days after surgery. Choice B is incorrect as bending at the waist can increase intraocular pressure, which should be avoided postoperatively. Choice C is incorrect as there is no need to avoid sleeping on the side of the body that was operated on after cataract surgery.

Correct Answer: B

Rationale: Correct Answer: The healthcare professional should review serum creatinine levels before administering metformin to assess kidney function. Metformin is excreted by the kidneys, and checking serum creatinine helps prevent lactic acidosis, a potential side effect in individuals with impaired renal function. Choice A: Potassium levels are not directly related to the administration of metformin. While monitoring potassium levels is important for some medications, it is not the priority when initiating metformin. Choice C: Sodium levels are not typically assessed specifically before starting metformin. It is not a routine lab test required prior to metformin administration. Choice D: Hemoglobin A1C reflects long-term blood sugar control and is not a lab test that needs to be reviewed before initiating metformin. It is used to monitor diabetes management over time, not for immediate medication administration considerations.

Correct Answer: D

Rationale: The correct statement is D: 'An RN evaluates the client's needs to determine which tasks are appropriate to delegate to assistive personnel.' This is an essential step in the delegation process to ensure that tasks are assigned appropriately based on the client's condition and the competencies of the assistive personnel. Option A is incorrect because while the nurse retains accountability for delegation decisions, the AP is responsible for their actions. Option B is incorrect as tasks should be within the AP's scope of practice regardless of training. Option C is incorrect as delegation typically involves assigning tasks from the RN to the AP, not between APs.
