Correct Answer: B

Rationale: The correct answer is B: 'Opens mouth when food comes her way.' This behavior indicates readiness to start trying solid foods. Infants should be introduced to solid foods based on developmental cues, such as showing an interest in food and the ability to accept it. Choices A, C, and D are not indicative of readiness for solid foods. Stopping rooting when hungry is a reflex that may persist beyond the readiness for solids. Awakening for nighttime feedings is a normal behavior for a 4-month-old, and transitioning from a bottle to a cup is a later developmental milestone.

Correct Answer: B

Rationale: The correct answer is B: 'I will give my baby iron-fortified cereal.' Iron-fortified cereal is an excellent source of iron for infants, aiding in the prevention of iron deficiency anemia. Choice A is incorrect as whole cow's milk should not be introduced until the child is at least 12 months old to prevent iron deficiency. Choice C is incorrect because giving fruit juice between meals can interfere with iron absorption. Choice D is incorrect as giving water with meals can decrease nutrient intake. Therefore, the best choice to prevent iron deficiency anemia in a 9-month-old infant is to give them iron-fortified cereal.

Correct Answer: D

Rationale: The priority action for the nurse is to review the immunization documentation of the child with HIV. This step ensures that the child has received the necessary vaccines to protect against pertussis and other preventable diseases. It is essential to verify the immunization status to provide appropriate care and prevent further transmission of infectious diseases within the foster home. Removing the child from the foster home (Choice A) may not be necessary if the child is adequately protected through immunization. Reporting the exposure to the health department (Choice B) is important but not the first action. Placing the child in reverse isolation (Choice C) is not indicated for pertussis exposure.

Correct Answer: B

Rationale: Introducing solid foods when the child opens their mouth for food is important to ensure readiness for solids. This behavior indicates the infant's interest and readiness for new textures and flavors, promoting safe and successful introduction to solid foods. The other choices are not indicative of the infant's readiness for solid foods: A - stopping rooting is a reflex action, C - awakening for nighttime feedings is a normal behavior, and D - transitioning from a bottle to a cup is a developmental milestone unrelated to solid food introduction.
