The nurse is inspecting the genitals of a prepubescent girl. Which is a normal sign of the onset of puberty?

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. TympaniC. Tympanic temperature measurement using an ear thermometer is a convenient and accurate method for assessing temperature in children, including toddlers.

B. Oral: Oral temperature measurement using a digital thermometer placed under the tongue is a commonly used method for children who can cooperate with the procedure and keep the

thermometer in their mouth.

C. Axillary: Axillary temperature measurement using a thermometer placed in the armpit is a non-invasive method suitable for children who cannot cooperate with oral or tympanic

measurements or when rectal measurement is contraindicated.

D. Rectal: Rectal temperature measurement is generally considered the most accurate method for assessing temperature in infants and young children, especially when accuracy is critical.

However, it may be less appropriate in the emergency department setting due to its invasive nature and potential discomfort for the child, especially in cases of diarrhea or vomiting where rectal temperature measurement may be difficult or impractical.
