What interventions should be implemented to maintain the skin integrity of a preterm infant born at 30 weeks?

Correct Answer: B

Rationale: The correct intervention to maintain the skin integrity of a preterm infant born at 30 weeks is to bathe the infant with sterile water. Bathing with sterile water or a neutral pH solution is recommended to protect the delicate skin of preterm infants, which is more permeable and prone to damage. Choices A, C, and D are incorrect as avoiding cleaning the skin may lead to hygiene issues, cleansing with alkaline-based soap can be harsh on the delicate skin, and thoroughly rinsing with plain water after bathing may not be as gentle and protective for preterm infants.

Correct Answer: C

Rationale: The FACES Pain Rating Scale is suitable for children as young as 3 years of age. It uses facial expressions to depict different levels of pain, making it easy for young children to understand and use. The Poker Chip Tool is validated for children aged 4 and older who have a certain level of cognitive ability. The Visual Analog Scale is more appropriate for children aged 7 and above. The Word-Graphic Rating Scale, which uses descriptive words, is recommended for children in the age range of 4 to 17 years.

Correct Answer: B

Rationale: When switching from intravenous to oral morphine, a higher oral dose is required to achieve equianalgesia due to significant metabolism from the first-pass effect. Choosing the same oral dose as the intravenous dose would provide less pain relief. Opting for a dose greater than the intravenous dose is necessary to achieve the same analgesic effect. Therefore, options A, C, and D are incorrect.

Correct Answer: B

Rationale: The correct site to administer an intramuscular (IM) vaccine to a newborn is the vastus lateralis muscle. For newborns, the vastus lateralis is preferred over the dorsogluteal site because the dorsogluteal site has been associated with low antibody seroconversion rates, indicating a reduced immune response. The vastus lateralis is also recommended for IM injections in newborns, while the deltoid muscle is preferred for older infants and children. The ventral gluteal muscle and the biceps muscle are not appropriate sites for IM injections. Therefore, choice B is the correct answer.
