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 A
Explanation
Physiologic jaundice usually appears between the second and fourth day after birth and resolves by the second week. It is caused by the immature liver's inability to process bilirubin efficiently.
Correct Answer is B
Explanation
Check the client's fundus. Lochia rubra is the normal vaginal bleeding and discharge that occurs after childbirth. It consists of blood, mucus, and tissue from the placenta and the uterus lining. It is usually bright red and may have some clots, but these clots should not be big or difficult to pass. If the client has a large amount of lochia rubra with several clots, it may indicate that the uterus is not contracting well and needs to be massaged to expel any retained tissue or blood. Checking the client's fundus is the first action the nurse should take to assess the uterine tone and location.
Choice A is incorrect because requesting the provider perform a vaginal examination is not the first action the nurse should take. A vaginal examination may be necessary if the fundal massage does not reduce the bleeding or if there is a suspicion of lacerations or hematoma, but it is not a priority intervention.
Choice C is incorrect because measuring the client's vital signs is not the first action the nurse should take. Vital signs can help monitor the client's hemodynamic status and identify signs of shock, such as tachycardia, hypotension, and pallor, but they are not as important as checking the fundus in this situation.
Choice D is incorrect because feeling for a full bladder is not the first action the nurse should take. A full bladder can displace the uterus and interfere with its contraction, leading to increased bleeding. However, it is not as likely as uterine atony to cause a large amount of lochia rubra with several clots.
