The nurse performing a health history on a child asks the parents if their child has experienced increased appetite or thirst. What body system is the nurse assessing with this question?

A. Telling about safety procedures during baths: While bath safety is important, it may not be the most relevant topic for a 9-month-old, who may already have established bathing routines. Additionally, the focus of anticipatory guidance at this age is often broader than just one specific activity.

B. Warning about small objects left on the floor: While important for safety, this advice may be more pertinent when the child is older and more mobile. At 9 months, infants are typically not yet crawling or exploring the environment as extensively.

C. Advising how to create a toddler-safe homE. At 9 months, infants are becoming more mobile and curious, so advising on how to create a safe environment is crucial to prevent accidents and injuries as the child begins to explore their surroundings.

D. Cautioning about putting the baby in a walker: Walkers are generally not recommended due to safety concerns, but this advice may be more relevant when the child is closer to reaching the appropriate age for walker use.

A. "I will give him a pacifier during feeding time.": Giving a pacifier during feeding time may interfere with the infant's ability to coordinate sucking, swallowing, and breathing, especially if

they are receiving nutrition through a nasogastric tube. This response indicates a need for further teaching because pacifiers during feeding time could potentially disrupt the infant's feeding

pattern and may not be appropriate in this situation.

B. "We need to make sure he doesn't lose the desire to eat by mouth.": This response

demonstrates an understanding of the importance of maintaining the infant's oral feeding skills and indicates appropriate knowledge about promoting oral feeding while using a nasogastric

tube.

C. "We need to keep feeding time very quiet.": Keeping feeding time quiet can help reduce distractions and promote a calm environment, which may enhance feeding tolerance for the infant. This response reflects an understanding of strategies to facilitate feeding.

D. "Sucking produces saliva, which aids in digestion.": This response demonstrates knowledge about the benefits of sucking and saliva production during feeding, indicating an understanding of the infant's physiological needs during feeding.
