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 D
Explanation
Precipitous birth
This is because precipitous birth, which is defined as a labor that lasts less than three hours from the onset of contractions to delivery, is a risk factor for postpartum hemorrhage. This is because the uterus may not contract well after a rapid delivery, leading to uterine atony and bleeding. Other risk factors for postpartum hemorrhage include uterine overdistension, oxytocin use, placental abruption, placenta previa, infection, coagulation disorders, and previous history of postpartum hemorrhage.
Choice A is not correct because gestational hypertension is not a risk factor for postpartum hemorrhage. It is a condition that causes high blood pressure during pregnancy and can lead to complications such as preeclampsia, eclampsia, and placental abruption³.
Choice B is not correct because small for gestational age newborn is not a risk factor for postpartum hemorrhage. It is a condition that indicates that the baby's growth was restricted in the womb and weighs less than 90% of other babies of the same gestational age. It can be caused by maternal factors, placental factors, or fetal factors⁴.
Choice C is not correct because a two-vessel umbilical cord is not a risk factor for postpartum hemorrhage. It is a condition that occurs when the umbilical cord has only one artery and one vein instead of the normal two arteries and one vein. It can be associated with congenital anomalies, intrauterine growth restriction, and stillbirth.
Correct Answer is D
Explanation
Ineffective airway clearance related to mucus and water secretions. This is because newborns who are born via cesarean delivery are at risk for respiratory distress due to the lack of compression of the chest during birth. This can result in retained mucus and fluid in the lungs that can interfere with breathing and oxygenation. The nurse should prioritize clearing the airway and monitoring the respiratory status of the newborn.
Choice A is wrong because ineffective thermoregulation related to heat loss to the environment is not specific to cesarean delivery. All newborns are prone to heat loss due to their large surface area and thin skin. The nurse should maintain a warm and dry environment for the newborn and prevent exposure to cold surfaces.
Choice B is wrong because altered nutrition less than the body requirement related to limited formula intake is not specific to cesarean delivery. All newborns need adequate nutrition to support their growth and development. The nurse should monitor the intake and output of the newborn and assist with feeding as needed.
Choice C is wrong because altered urinary elimination related to post- circumcision status is not specific to cesarean delivery. Circumcision is an elective procedure that may or may not be performed on male newborns. The nurse should provide wound care and pain relief for the circumcised newborn and observe for signs of infection or bleeding.
