2024 PN NCLEX Questions Nursing Practice Question
Intramuscular (IM) phytonadione (vitamin K) 0.5 mg is prescribed for a newborn. After the medication is prepared, in which anatomic site does the nurse administer it?
Correct Answer: D
Rationale: Administering intramuscular phytonadione to a newborn requires careful consideration of anatomical sites. The vastus lateralis muscle (D) is the preferred site for infants due to its size and depth, minimizing the risk of injury to nerves or blood vessels.
The rectus femoris muscle (A) is less commonly used in infants due to its proximity to major nerves and vessels, making it a less safe option. The deltoid muscle (B) is typically not recommended for newborns due to its underdevelopment and smaller muscle mass. The gluteal muscle (C) is avoided in infants because of the potential for sciatic nerve injury and the risk of inadequate muscle development.
