A nurse is caring for a 30-month-old child. Which of the following activities should the nurse expect the child to participate in?

A) Playing with an imaginary friend: While imaginative play does begin to develop in toddlers, having an imaginary friend is more typical in older preschool-aged children, around 3 to 4 years old. Therefore, this activity may not be expected in a 30-month-old child.

B) Playing with a large plastic truck: At 30 months old, children are typically engaged in parallel play and are interested in toys that promote gross motor skills and imaginative play. Playing with a large plastic truck is developmentally appropriate, as children at this age enjoy manipulating vehicles and may engage in simple pretend play related to driving or racing.

C) Playing with dress-up clothes: Although some children may enjoy dress-up, this activity tends to be more prominent in slightly older toddlers and preschoolers. A 30-month-old may show interest in dressing up but may not engage in it as frequently or with as much understanding of role play as older children.

D) Playing with a jump rope: Jump rope activities require a level of coordination and motor skills that are typically beyond what a 30-month-old child can achieve. At this age, children are still developing basic motor skills and would not yet be proficient in using a jump rope effectively.

A) Flumazenil: Flumazenil is a benzodiazepine antagonist used to reverse the effects of benzodiazepine overdose. Since the client received hydromorphone, which is an opioid, flumazenil would not be the appropriate medication to administer in this situation. The respiratory depression is likely due to opioid use, so this option does not address the client’s specific needs.

B) Protamine: Protamine is a medication used to reverse the effects of heparin, an anticoagulant. It is not indicated for opioid overdose or respiratory depression caused by opioids. Therefore, administering protamine would not be relevant in this scenario and would not help address the client's low respiratory rate.

C) Acetylcysteine: Acetylcysteine is primarily used as an antidote for acetaminophen overdose and to help loosen mucus in conditions like cystic fibrosis. It does not have a role in reversing opioid effects. The client’s respiratory depression following hydromorphone administration would not be treated with acetylcysteine.

D) Naloxone: Naloxone is an opioid antagonist specifically designed to reverse the effects of opioid medications, including respiratory depression. Given that the client is experiencing a significantly low respiratory rate of 10/min after receiving hydromorphone, naloxone is the most appropriate medication to administer promptly to restore normal respiratory function.
