An infant with bronchiolitis is hospitalized. The causative organism is RSV. The nurse knows that a child infected with this virus requires the following isolation:

A. FACES
The FACES scale, often depicted with a series of faces displaying different expressions, is commonly used for children who can understand and respond to a scale of faces indicating different levels of pain. It is suitable for older children who can articulate their feelings.

B. FLACC
The FLACC (Face, Legs, Activity, Cry, Consolability) scale is commonly used to assess pain in preverbal and non-verbal children, such as a 4-year-old. It evaluates the child's facial expression, leg movement, activity level, cry, and ease of consolability to determine the level of pain.
C. APPT
There is no widely recognized pain assessment tool referred to as "APPT." It may be a term specific to a certain context or institution.

D. Numeric
Numeric pain scales involve asking individuals to rate their pain on a numerical scale, usually ranging from 0 to 10. These scales are often used with older children and adults who can understand and communicate numerical values to describe their pain intensity.

A. The child's current vital signs are consistent with vital signs over the past 4 hours.

Vital signs alone may not be sufficient to assess pain in a child. Children may experience pain without significant changes in vital signs. Behavioral cues and self-reporting are important indicators of pain in pediatric patients.

B. The child becomes quiet when held and cuddled.

While seeking comfort through cuddling may be a sign of distress or discomfort, it is not specific enough to determine the need for pain medication. Additional assessment is required to understand the underlying cause of the child's change in behavior.

C. The child has a temperature of 38.5°C.

Fever alone does not necessarily indicate the need for pain medication. It may suggest an infection or illness, but the specific assessment of pain requires consideration of the child's behavior, verbal expressions, and any other cues related to pain.

D. The child is lying stiffly in bed, not moving, and refusing to get up.

In this scenario, the child's behavior of lying stiffly in bed, not moving, and refusing to get up is indicative of potential pain. Children may express pain in various ways, and behavioral cues such as changes in activity, refusal to move, or guarding certain body parts can suggest discomfort. It is important for the nurse to assess and address the child's pain promptly.
