A nurse is preparing to administer cephalexin 50 mg/kg/day in divided doses every 8 hours to a child who weighs 33 lb. The amount available is cephalexin oral suspension 250 mg/5 mL.

How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) .

1. Jitteriness: Jitteriness can be seen in hypoglycemia (due to low blood sugar), neonatal sepsis (which causes systemic effects including jitteriness), and neonatal abstinence syndrome (due to withdrawal from maternal substances).
2. Poor feeding: Poor feeding is consistent with hypoglycemia (due to low energy reserves), neonatal sepsis (due to general ill-health), and neonatal abstinence syndrome (as a withdrawal symptom).
3. Petechiae on the chest: Petechiae is a sign of neonatal sepsis, which can result from bacterial infections or other causes affecting the clotting system. It is not typically seen in hypoglycemia, neonatal abstinence syndrome, or hyperbilirubinemia.
4. Blood glucose 35 mg/dL: This is a hallmark sign of hypoglycemia, indicating a dangerously low level of glucose in the blood.
5. High-pitched cry: A high-pitched cry is a classic symptom of neonatal abstinence syndrome, often seen in infants withdrawing from opioids or other substances. It is not a typical sign of hypoglycemia, neonatal sepsis, or hyperbilirubinemia.

Choice A rationale

Worrying about physical body changes is more typical of older children or adolescents who have a greater understanding of body image and self-concept. Preschoolers are usually not as concerned about changes in their physical appearance in relation to death, as their cognitive development is not yet at that level of comprehension.

Choice B rationale

Feelings of isolation are more commonly associated with older children and adolescents who have a better understanding of social relationships and separation. Preschoolers are more focused on immediate relationships and may not fully grasp the concept of isolation as it relates to death.

Choice C rationale

Preschoolers often perceive death as a punishment due to their egocentric thinking and limited understanding of cause and effect. They may believe that their actions or behavior have directly caused the death or that it is a form of retribution. This perception is a normal part of their cognitive and emotional development.

Choice D rationale

Understanding that death is permanent is a cognitive milestone that typically develops in later childhood. Preschoolers generally do not comprehend the finality of death and may see it as a temporary or reversible state. Their thinking is more concrete and influenced by their immediate experiences and observations. .
