A 4-year-old child with a history of cystic fibrosis (CF) presents to the clinic for a routine follow-up. The parents report that the child has had an increase in productive cough, wheezing, and shortness of breath over the past few days. Upon examination, the child has clubbed fingers, and chest auscultation reveals decreased breath sounds. Given these findings, which of the following interventions should the nurse prioritize to manage the child's condition and prevent further respiratory complications?

A. This scale asks the child to verbally rate their pain on a scale from 0 (no pain) to 10 (worst pain). It requires understanding of numbers, abstract thinking, and the ability to quantify pain, which is beyond the cognitive level of most 5-year-old preschoolers. Since the child in this scenario has difficulty understanding numbers, using the NRS would likely lead to inaccurate or unreliable pain assessment.

B. The VAS requires the child to mark a point along a continuous line representing pain intensity, usually anchored with “no pain” at one end and “worst pain” at the other. This tool requires abstract thinking, spatial awareness, and fine motor skills, which preschoolers may not have fully developed. A 5-year-old may not comprehend the concept of a continuous gradient or how to place a mark accurately, making this scale inappropriate.

C. The FLACC scale assesses pain based on observational behaviors: Face, Legs, Activity, Cry, and Consolability. It is designed for infants, toddlers, or children who are nonverbal or unable to self-report. While effective for behavioral assessment, FLACC does not allow the child to self-report pain, which is considered the gold standard whenever possible. Since this child can speak, the nurse should use a tool that allows self-expression rather than relying solely on observation.

D. This scale presents a series of faces ranging from a happy face (no pain) to a crying face (worst pain). Children point to the face that best represents their pain, allowing self-reporting without needing to understand numbers. It is validated for children aged 4–12 years and is developmentally appropriate for a 5-year-old preschooler. It accommodates children who have difficulty with numerical concepts but can interpret visual expressions of discomfort. Additionally, it encourages active participation in pain assessment, improves communication between the child and caregiver, and can guide pain management decisions accurately.

A. While cold compresses can reduce local pain and inflammation, they do not address the systemic risk of tetanus. Given the child’s symptoms (stiff jaw, muscle spasms, difficulty swallowing) 10 days after stepping on a rusty nail, tetanus is suspected, and simply treating the wound locally is insufficient.

B. Muscle stiffness and spasms in tetanus are caused by neurotoxin effects on the nervous system, not inactivity. Ambulation does not prevent the progression of tetanus and could increase the risk of falls or injury.

C. The child’s clinical presentation is consistent with tetanus, which is a medical emergency. The priority intervention is to neutralize the toxin and provide active and passive immunization. The tetanus booster stimulates active immunity, while tetanus immune globulin (TIG) provides immediate passive immunity to neutralize circulating toxin. This intervention is life-saving and takes priority over local wound care or antibiotics.

D. Antibiotics like metronidazole or penicillin are used to reduce bacterial load, but they do not neutralize circulating tetanus toxin and are secondary to immediate immunotherapy. Delaying TIG while focusing only on antibiotics could be fatal.
