Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Chapter Review Physiological differences between ages will affect your care (for example: differences in respiratory systems; effects of pre-existing conditions). Infants and young children have less- developed, smaller respiratory structures which can worsen respiratory conditions. continued
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Chapter Review Communicating with patients will depend on their stage of development: could be fear of strangers, separation anxiety, embarrassment, denial, depression.
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Remember Infants present massive bursts of anatomical and psychosocial development in the first year of life. Although preschoolers begin to develop independence and reason, in many ways they still resemble the psychosocial development of toddlers. continued
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Remember School-age children often are independent and logical, but that may crumble with illness or injury. Adolescents are reaching physiological maturity, but they often face difficult psychosocial challenges. continued

She is with friends at the park. She seems hesitant to answer any of your questions. What characteristic of adolescent development is most likely the cause of this? How could you overcome it?
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Summary (1 of 6) Whereas each developmental stage is marked by different physical and psychosocial changes and characteristics, infants (1 month to 1 year) develop at a startling rate.
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Summary (2 of 6) The vital signs of toddlers (ages 1 to 3 years) and preschoolers (ages 3 to 6 years) differ somewhat from those of an infant. During the toddler stage, children learn to speak and express themselves.
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Summary (3 of 6) From ages 6 to 12 years, the school-age child’s vital signs and body gradually approach those observed in adulthood. During this stage, children develop self- esteem.
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Summary (4 of 6) The vital signs of adolescents (ages 12 to 18 years) begin to level off within the adult ranges. Adolescents focus on creating their self-image.

Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Review 1.When providing bag-mask ventilations to an infant, what is most important to remember? A.Blood pressure typically increases with age. B.An infant’s lungs are fragile. C.An infant grows at a rate of about 30 g per day. D.An infant has a proportionately larger tongue than an adult.
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Review Answer: B Rationale: It is important to remember that an infant’s lungs are fragile; ventilations that are too forceful can result in trauma from pressure, or barotrauma. Due to the large size of the infant’s occiput and the increased flexibility of the trachea, the airway can easily be inadvertently occluded by incorrect positioning, either overextension or overflexion.

Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Review 1.When providing bag-mask ventilations to an infant, what is most important to remember? A.Blood pressure typically increases with age.

Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Review 1.When providing bag-mask ventilations to an infant, what is most important to remember? C.An infant grows at a rate of about 30 g per day. Rationale: This is not crucial information when giving ventilations. D.An infant has a proportionately larger tongue than an adult. Rationale: The large tongue could occlude the airway, but it is more important to remember the fragility of the lungs.

Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Review Answer: C Rationale: An infant’s psychosocial development begins at birth and continues to evolve as the infant interacts with, and reacts to, the environment. At 4 months of age, an infant is likely to start reaching out to people and drooling.
Copyright ©2012 by Pearson Education, Inc. All rights reserved. Emergency Care, Twelfth Edition Limmer O’Keefe Dickinson Review 2.You see an infant capable of reaching out to people and drooling.
