Final answer:
The correct actions a nurse should take for a preschooler in a pediatric unit depend on the specific assessment findings but commonly include monitoring vital signs and administering necessary fluids such as 0.9% sodium chloride IV. Discontinuation of oxygen or administration of epinephrine are contingent on the patient's condition. An IV delivery order by a physician must be carefully prepared or retrieved according to hospital protocol.
Step-by-step explanation:
The subject question pertains to the appropriate nursing actions after performing an assessment on a preschool child in the pediatric unit. While the provided information does not detail the specific assessment findings, the correct actions would most likely include:
- Monitoring vital signs frequently to ensure stability and detect any changes in the child's condition.
- Considering the administration of 0.9% sodium chloride IV if the child is dehydrated or requires fluid replacement for another reason.
The actions to discontinue supplemental oxygen or to administer epinephrine IM are situation-dependent and cannot be selected without additional context such as the child's oxygen levels or a presentation of an allergic reaction requiring epinephrine.
In the scenario where a physician orders an intravenous (IV) delivery of 100 mL of 0.5% KCl for a patient with hypokalemia, typically hospital protocol would have a staff member retrieve the appropriate IV bag from the supply if available or prepare it following hospital guidelines to ensure accurate concentration and sterility.
