A nurse is assisting with teaching a class about Piaget's stages of cognitive development. The nurse should reinforce that abstract thinking develops during which of the following stages?

Choice A reason : Going to bed at the same time every night, even when not feeling tired, can help regulate the body's clock and aid in falling asleep at a regular time. However, lying in bed awake can lead to frustration and should be avoided. If sleep does not come within 20 minutes, it's recommended to get up and do something relaxing until feeling sleepy.

Choice B reason : Exercising can increase alertness and endorphin levels which can make it difficult to fall asleep if done too close to bedtime. Stopping exercise at least 2 hours before bedtime allows the body to wind down and prepare for sleep, making this statement correct and indicative of an understanding of good sleep hygiene practices.

Choice C reason : Watching television or engaging in other stimulating activities in the bedroom can associate the space with wakefulness rather than sleep. The light from screens can also suppress melatonin production, making it harder to fall asleep. Therefore, this statement does not reflect an understanding of the teaching on good sleep practices.

Choice D reason : Taking long naps, especially in the late afternoon or evening, can interfere with nighttime sleep. If naps are necessary, they should be limited to 20-30 minutes and taken earlier in the day. This statement suggests a misunderstanding of the impact of napping on sleep quality at night.

Choice A reason : Determining the success of coping strategies is an important part of the nursing process, but it is not the first step when caring for a client experiencing grief. The initial step should be to assess the client's current state, including their grieving process, before evaluating the effectiveness of past coping strategies.

Choice B reason : Establishing whether the client's grieving is healthy or complicated is the first action the nurse should take according to the nursing process. This assessment helps to identify the client's needs and guides the subsequent planning of care. Healthy grieving is a natural response to loss, whereas complicated grief may require more intensive intervention and support.

Choice C reason : Developing client-specific goals and outcomes is a crucial part of the nursing process but should come after the nurse has established a clear understanding of the client's grieving process. Goals and outcomes should be based on the initial assessment and tailored to the client's individual situation.

Choice D reason : Incorporating the treatment into the client's care is part of the implementation phase of the nursing process. This step occurs after the nurse has assessed the client, established goals, and planned interventions. Treatment should be based on a thorough understanding of the client's grieving process.
