A nurse is preparing to administer recommended immunizations to a 4-year-old child who is up-to-date on current immunizations and severely immunocompromised. Which of the following immunizations should the nurse plan to administer?

A. The Poker Chip Tool is used to assess pain in children who can understand the concept of "a few" to "lots" of pain, typically in older children. It is not appropriate for infants or toddlers.

B. The Color tool is used for children who can associate color with pain intensity, but it is generally for older children who can understand this system, not for infants.

C. The Numeric scale is designed for children who are old enough to understand and use numbers (typically older than 8 years). An 18-month-old would not be able to understand this scale.

D. The FLACC (Face, Legs, Activity, Cry, Consolability) scale is specifically designed to assess pain in infants and nonverbal children. It uses behavioral indicators to rate pain intensity and is appropriate for an 18-month-old toddler.

A. Redness at the injection site is a common and mild reaction to vaccines. It does not typically require immediate medical intervention unless it worsens or is accompanied by more severe symptoms.

B. A temperature of 37.7° C (99.9° F) is a low-grade fever, which is a common, expected response after immunization. It is not a priority unless it increases significantly or is accompanied by other concerning symptoms.

C. Prolonged crying can sometimes occur after immunizations, but it is usually self-limited and resolves within a short period. If the crying is not excessive and does not indicate distress, it is generally not a priority concern.

D. Hives on the child’s neck could be a sign of an allergic reaction, such as anaphylaxis, which is a medical emergency. The nurse should immediately assess the child’s airway and provide necessary interventions, such as administering epinephrine, if required. This finding is the priority because it suggests a possible severe allergic response
