The nurse providing feeding instructions to a family with a newborn with cleft lip and palate will include:

Choice A reason: This statement is correct, as asking about the child's contacts over the last three weeks can help the nurse identify the possible source of infection and the risk of transmission. Rubella is a viral infection that spreads through respiratory droplets or direct contact with an infected person. The incubation period of rubella is 14 to 21 days, meaning that the child could have been exposed to the virus up to three weeks before developing symptoms.

Choice B reason: This statement is incorrect, as asking about the child's immunizations is not the most effective way to determine how the child was exposed to the virus. Although immunization can prevent rubella infection, it is not 100% effective, and some children may still get the disease despite being vaccinated. The nurse should also consider other factors, such as the child's medical history, travel history, and exposure to other people with rash or fever.

Choice C reason: This statement is incorrect, as asking about the medications given to the child is not the most effective way to determine how the child was exposed to the virus. Medications can help relieve the symptoms of rubella, such as fever, rash, or joint pain, but they do not affect the transmission or the course of the infection. The nurse should focus on the epidemiological aspects of the disease, such as the mode of transmission, the incubation period, and the contagious period.

Choice D reason: This statement is incorrect, as asking about the onset of the rash is not the most effective way to determine how the child was exposed to the virus. The rash of rubella usually appears 14 to 17 days after exposure, and lasts for about three days. However, the child can be contagious from seven days before to seven days after the rash appears, meaning that the child could have been exposed to the virus up to four weeks before or after the rash. The nurse should ask about the child's contacts during this period, not just the rash.

Choice A reason: This statement is incorrect, as letting the child feed herself finger foods is not a risk factor for aspiration, but a way to promote self-feeding skills, independence, and appetite. The nurse should encourage the parents to offer the child a variety of soft, bite-sized, and nutritious foods, such as cooked vegetables, fruits, cheese, or bread, and to supervise the child during meals.

Choice B reason: This statement is correct, as giving whole milk is recommended for children between 1 and 2 years old, as it provides adequate fat, protein, calcium, and vitamin D for their growth and development. The nurse should advise the parents to give the child about 16 to 24 ounces of whole milk per day, and to avoid low-fat or skim milk until the child is 2 years old.

Choice C reason: This statement is incorrect, as delaying the introduction of foods which may cause allergies is not necessary or beneficial for the prevention of food allergies in children. The nurse should inform the parents that there is no evidence that avoiding certain foods, such as eggs, peanuts, or fish, can reduce the risk of food allergies, and that introducing these foods early, around 6 months of age, may actually prevent or reduce the severity of food allergies.

Choice D reason: This statement is incorrect, as transitioning to 1% milk is not advisable for children under 2 years old, as it does not provide enough fat and calories for their growth and development. The nurse should explain to the parents that low-fat or skim milk is not suitable for young children, as they need more fat for their brain and nervous system development, and that switching to 1% milk should only be done after consulting with the doctor.
