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 : Administering an opioid narcotic can be an effective measure for managing dyspnea in end-of-life care. Opioids, such as morphine, can reduce the sensation of breathlessness and improve comfort without significantly affecting oxygen saturation levels. The use of opioids is a well-established practice in palliative care for the relief of dyspnea, particularly when other causes of dyspnea have been addressed and managed appropriately.

Choice B reason : Increasing the heat in the client's room is not a recommended action for managing dyspnea and may actually worsen the client's comfort. Patients experiencing dyspnea often feel better in a cooler environment, as warm temperatures can make breathing feel more labored⁴.

Choice C reason : Placing the head of the client's bed flat is not advisable for managing dyspnea. Elevating the head of the bed can help ease breathing by reducing pressure on the diaphragm and allowing for better lung expansion. A semi-upright position, such as Fowler's or semi-Fowler's position, is typically recommended for patients experiencing dyspnea.

Choice D reason : Nasotracheal suctioning is a procedure used to clear secretions from the airway. While it may be necessary in some cases, it is not a standard action for managing dyspnea in end-of-life care unless there is a specific indication, such as excessive secretions that the patient cannot clear on their own. It can be uncomfortable and distressing for the patient and should be used judiciously⁵.

Choice A reason : Increasing intake of saturated fats is not recommended for reducing stress. Saturated fats can contribute to the development of heart disease by raising cholesterol levels and should be limited in a healthy diet.

Choice B reason : Limiting alcohol intake is generally a good practice, but specifying "3 drinks per day" is not accurate. The Dietary Guidelines for Americans recommend up to one drink per day for women and up to two drinks per day for men.

Choice C reason : Choosing complex carbohydrates each day is beneficial for managing stress. Complex carbohydrates can increase the amount of serotonin in the brain, which has a calming effect. Foods rich in complex carbohydrates include whole grains, fruits, vegetables, and legumes⁷.

Choice D reason : Consuming less than 2000 mg of sodium per day is part of a healthy diet, but it is not specifically related to stress reduction. The American Heart Association recommends no more than 2300 mg a day and moving toward an ideal limit of no more than 1500 mg per day for most adults.
