A nurse is teaching an older adult client about vitamin D deficiency. The nurse should encourage the client to consume an adequate amount of vitamin D to prevent which of the following complications?

Choice A reason: Alternating the first breast that is offered to the baby with each feeding is a good practice for breastfeeding because it can ensure equal stimulation and drainage of both breasts, which can prevent engorgement, mastitis, or low milk supply. Alternating breasts can also provide the baby with both foremilk and hindmilk, which have different compositions and benefits.

Choice B reason: Storing breast milk in the refrigerator up to 48 hours is not a good practice for breastfeeding because it can reduce the quality and safety of the milk. Breast milk should be stored in the refrigerator for no longer than 24 hours or in the freezer for no longer than 6 months. Breast milk should also be stored in clean, sterile containers and labeled with the date and time of expression.

Choice C reason: Nursing the baby once every 4 hours is not a good practice for breastfeeding because it can decrease the milk production and supply, which can affect the growth and development of the baby. Breastfeeding should be done on demand or at least every 2 to 3 hours during the day and every 3 to 4 hours at night. Breastfeeding should also last for at least 10 to 15 minutes per breast or until the baby is satisfied.

Choice D reason: Offering the baby water between feedings is not a good practice for breastfeeding because it can interfere with the baby's appetite and intake of breast milk, which can cause dehydration, malnutrition, or failure to thrive. Breast milk contains enough water and nutrients to meet the baby's needs for the first six months of life. Water should be avoided or limited until the baby starts solid foods.

Choice A reason: Providing a snack 30 min before treatments can worsen nausea and diarrhea, as food can stimulate gastric motility and secretion. It is better to avoid eating for at least 2 hours before and after treatments.

Choice B reason: Ensuring foods are served hot can increase nausea and diarrhea, as hot foods can have strong smells and irritate the digestive tract. It is better to serve foods at room temperature or cold.

Choice C reason: Administering antiemetics on a schedule can prevent nausea and vomiting, which can lead to dehydration and electrolyte imbalance. Antiemetics can also reduce abdominal cramps and spasms that cause diarrhea.

Choice D reason: Serving low carbohydrate meals can aggravate diarrhea, as carbohydrates are the main source of energy for the body. It is better to serve high carbohydrate meals that are easy to digest, such as rice, potatoes, bread, or crackers.
