A nurse is giving an intramuscular injection to a newborn who was delivered at 38 weeks of gestation. Which of the following pain scales should the nurse use to assess the newborn's pain?

Choice A reason:A. Natal Infant Pain Scale (NIPS): The NIPS is a behavioral assessment tool designed for both preterm and full-term neonates. It evaluates six behavioral indicators in response to painful procedures. These indicators include changes in facial expression (such as grimacing, brow bulge, and eye squeeze), body movements (such as fisting, tremulousness, and limb withdrawal), and other signs of distress Choice B reason: FACES pain rating scale The FACES pain rating scale should not be used because it is a visual scale that uses facial expressions to assess pain in children who can communicate using pictures of faces displaying different emotions. It is generally used for older children and not appropriate for newborns. Choice C reason Premature Infant Pain Profile (PIPP): The PIPP is another pain assessment tool specifically developed for preterm infants. It considers physiological and behavioral parameters, including facial expressions, heart rate, oxygen saturation, and gestational age. While useful for preterm infants, it may not be the best choice for full-term newborns. Since the newborn in this scenario was delivered at 38 weeks of gestation, the PIPP would be an appropriate pain assessment tool to use. It considers specific physiological and behavioural indicators of pain in newborns and helps healthcare providers evaluate and manage pain in this vulnerable population. Choice D reason: Visual analog scale (VAS) should not be used because the visual analog scale is a pain assessment tool typically used for older children, adolescents, and adults who can understand and provide a subjective rating of their pain intensity along a linear scale. It involves marking a point on the line corresponding to the level of pain experienced. Since newborns cannot communicate in this way, the VAS is not suitable for their pain assessment.
