A nurse is teaching car seat safety to a parent of an infant who weighs 4.5 kg (10 lb). Which of the following car seat positions should the nurse include in the teaching?

A. "Activity will increase the respiratory rate": While activity can indeed affect respiratory rate, counting for a full minute allows for a more accurate assessment of the newborn's baseline respiratory rate, regardless of activity level.

B. "The rate and rhythm of breath are irregular in newborns": This statement reflects an understanding of why a complete minute is necessary for counting the respiratory rate in newborns. Newborns often have irregular breathing patterns, so counting for a full minute helps ensure an accurate assessment of their respiratory rate.

C. "Newborns are abdominal breathers": While newborns primarily use their diaphragm to

breathe (abdominal breathing), this fact alone does not explain why the respiratory rate should be counted for a full minute.

D. "Newborns do not expand their lungs fully with each respiration": While newborns may not fully expand their lungs with each breath, this factor is not the primary reason for counting the respiratory rate for a full minute.

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.
