Correct Answer: C

Rationale: The correct question for the nurse to ask the mother before administering the MMR vaccine to a 15-month-old is about the child's allergy to antibiotics. This is crucial because the MMR vaccine contains neomycin, an antibiotic, and being allergic to antibiotics like neomycin is a contraindication for the MMR vaccine. Asking about sore throats, eating habits, or exposure to infections is not directly relevant to the administration of the MMR vaccine.

Correct Answer: D

Rationale: The correct answer is D, Assessment. Assessment in nursing involves obtaining subjective information from the patient and their family to gather data about the patient's health status. This step is crucial as it helps identify the patient's needs, strengths, and areas requiring intervention. Choice A, Evaluation, is incorrect as evaluation comes after the implementation of the care plan to determine its effectiveness. Choice B, Planning, is also incorrect as it involves developing a plan of care based on the assessment data. Choice C, Implementation, is the phase where the nursing interventions are carried out based on the established care plan.

Choices A, B, and C are incorrect because they represent individual scenarios where disclosure can occur, but the comprehensive answer is that personal health information can be disclosed in all these situations, not just one or two.
