The nurse is preparing to administer the vitamin K injection to a newborn. Which action would be correct for this client?
Using a 21 gauge needle.
Injecting at a 45-degree angle.
Injecting 1cc of medication.
Injecting the medication into the vastus lateralis.
The Correct Answer is D
Injecting the medication into the vastus lateralis. This is because the vastus lateralis is a large muscle in the thigh that is suitable for intramuscular injections in newborns³. The vitamin K injection helps prevent vitamin K deficiency bleeding, which is a rare but serious condition that can cause bleeding in the brain or other organs¹. The American Academy of Pediatrics recommends that all newborns receive a single intramuscular dose of 0.5 to 1 mg of vitamin K within one hour of birth².
Choice A is wrong because a 21 gauge needle is too large for a newborn's muscle. A 25 or 27 gauge needle is more appropriate.
Choice B is wrong because injecting at a 45-degree angle may not reach the muscle tissue. A 90-degree angle is more appropriate.
Choice C is wrong because injecting 1cc of medication is too much for a newborn's muscle. The recommended dose of vitamin K is 0.5 to 1 mg, which is equivalent to 0.05 to 0.1 mL.

Correct Answer is B
Explanation
Your baby can lose 5% of body weight during the first 3 days of life. This is a normal physiological process that happens as your baby adjusts to breastfeeding and expels excess fluids. Your baby should regain this weight by 10 to 14 days of age.
Choice A is incorrect because your baby does not need to feed constantly in the first week of life. Your baby should feed at least eight times in 24 hours but may have periods of cluster feeding where they feed more frequently for a few hours.
Choice C is incorrect because your baby should have more than 5 wet diapers per day after the fourth day of life. This is a sign that your baby is getting enough milk and is well-hydrated.
Choice D is incorrect because your baby should gain more than 0.25 oz (7 grams) per day after the fourth day of life. The average weight gain for a breastfed baby is about 0.5 to 1 oz (14 to 28 grams) per day in the first month.
Correct Answer is D
Explanation
Rooting. The rooting reflex is a primitive neonatal reflex that helps the baby find the breast or bottle to start feeding. When the corner of the baby's mouth is stroked or touched, the baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This reflex lasts about 4 months.
Choice A. Sucking is not the correct answer because it is a different reflex that starts when the roof of the baby's mouth is touched, and it does not help the baby find the breast or bottle.
Choice B. Grasp is not the correct answer because it is a reflex that causes the baby to close his or her fingers in a grasp when the palm of the hand is stroked, and it has nothing to do with breastfeeding.
Choice C. Tonic neck is not the correct answer because it is a reflex that causes the baby to assume a "fencing" position when the head is turned to one side, and it also has nothing to do with breastfeeding.
