A nurse is caring for a client who has methicillin-resistant Staphylococcus aureus (MRSA) in an abdominal wound. The nurse enters the room to check the client's pulse. Which of the following items should the nurse wear?

Choice A reason: The severity of the condition may not always correlate with the level of pain experienced by the client. Pain is a subjective experience, and two individuals with the same condition may report different levels of pain.

Choice B reason: Vital signs can be indicators of pain but are not always reliable. For example, some clients may exhibit increased heart rate or blood pressure when in pain, while others may not show significant changes in vital signs despite severe pain.

Choice C reason: Nonverbal behavior can be an indicator of pain, especially in clients who are unable to communicate verbally. However, it is still considered less reliable than self-report because it is subject to interpretation by the observer.

Choice D reason: Self-report of pain is considered the most reliable indicator of a patient's pain experience. It is a direct expression of the client's experience and should be the primary source of assessment whenever possible.

Choice A reason: The FACES pain scale is commonly used for children who are able to select a face that best describes their pain. However, this scale is not suitable for a 6-month-old infant post-myringotomy, as infants of this age cannot verbally communicate or reliably choose a face to represent their pain level.

Choice B reason: The Visual Analog Scale (VAS) is typically used for older children and adults who can understand and indicate their level of pain by marking a point on a line. This scale is not appropriate for infants due to their developmental stage and inability to communicate or understand the concept of the scale.

Choice C reason: The Oucher pain scale includes both a photographic scale with pictures of children's faces showing different levels of pain and a numerical scale. While it is designed for children aged 3 to 12 years, it is not suitable for infants, as they cannot verbally express their pain or point to a photograph to indicate their pain level.

Choice D reason: The FLACC scale, which stands for Face, Legs, Activity, Cry, and Consolability, is an appropriate choice for assessing pain in infants and young children who are non-verbal. It involves observing specific behaviors and assigning a score from 0 to 2 for each category, resulting in a total score between 0 and 10. This observational tool allows healthcare providers to assess pain levels based on the infant's behavior and physiological responses.
