Correct Answer: C

Rationale: The correct answer is C: 'Enzymes should be taken before or with meals.' Pancreatic enzymes should be taken before or with meals to assist with digestion in children with cystic fibrosis. This timing helps maximize the effectiveness of the enzymes in breaking down nutrients from food. Giving the enzymes after meals (choice A) may not provide the necessary support for digestion. Mixing the enzymes with hot food or drinks (choice B) is not recommended as it may affect the enzymes' efficacy. Avoiding giving enzymes with any food or drink (choice D) is incorrect as enzymes need to be taken in conjunction with meals to aid in digestion.

Correct Answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.

Correct Answer: B

Rationale: Teaching children how to swim is valuable, but parental supervision around water is essential to prevent drowning. It's crucial to emphasize constant supervision when young children are near water, regardless of their swimming abilities. The other choices (A, C, and D) demonstrate appropriate safety measures for injury prevention in toddlers, such as securing cleaning supplies, ensuring helmet use during tricycle rides, and using a car seat for every car ride.

Correct Answer: D

Rationale: The correct response is D because it is believed that hearing is the last sense to go. Even if the dying person does not respond, speaking to them can still provide comfort. Choice A is incorrect because talking loudly is not necessary and can be distressing. Choice B is incorrect as it focuses on touch rather than the sense of hearing. Choice C is incorrect because sitting close may not necessarily help the dying person hear better.

Correct Answer: C

Rationale: In this scenario, the priority intervention for the nurse is to initiate a structured eating plan. Anorexia nervosa is a serious eating disorder characterized by severe food restriction, which can lead to malnutrition and severe weight loss. By starting a structured eating plan, the nurse can ensure the client receives the necessary nutrition to begin the process of weight restoration and recovery. Monitoring vital signs is essential, but without addressing the nutrition deficiency, vital signs may not improve significantly. Establishing a therapeutic relationship is crucial for long-term care but may not address the immediate risk of malnutrition. Providing education about healthy eating habits is important but may not be effective initially due to the severity of the client's condition.
