What could be the result of fetal head compression?
Uteroplacental insufficiency.
Spontaneous rupture of membranes.
Altered fetal cerebral blood flow.
Umbilical cord compression.
The Correct Answer is A
Choice A rationale: Uteroplacental insufficiency causes late decelerations due to reduced oxygenation, not mechanical pressure. It reflects placental dysfunction, not direct cranial compression effects.
Choice B rationale: Spontaneous rupture of membranes increases infection and labor risk but does not directly alter cerebral perfusion or trigger vagal responses linked to head compression.
Choice C rationale: Altered fetal cerebral blood flow results from cranial pressure during contractions, triggering vagal stimulation and early decelerations. This is the physiological response to head compression.
Choice D rationale: Umbilical cord compression causes variable decelerations due to transient blood flow obstruction, unrelated to cranial pressure or cerebral perfusion changes.

Correct Answer is C
Explanation
Choice A rationale
Inserting an indwelling urinary catheter is not the immediate next step. While it may be necessary in some cases, the priority is to address the client’s excessive bleeding, which is a sign of postpartum hemorrhage.
Choice B rationale
Administering oxytocin by continuous IV infusion is a common intervention for postpartum hemorrhage. However, it is not the immediate next step. The nurse should first attempt to massage the client’s fundus to promote contractions and control bleeding.
Choice C rationale
Massaging the client’s fundus is the correct next step. The client’s symptoms indicate postpartum hemorrhage, a serious condition that can lead to shock and other complications. Fundal massage often helps the uterus contract and can stop the bleeding.
Choice D rationale
Tilting the client onto her right side with her legs elevated to at least 30 degrees is not the immediate next step. This position can help improve venous return but does not directly address the cause of the client’s symptoms.
Correct Answer is B
Explanation
Choice A rationale
The deltoid muscle is not typically used for intramuscular injections in infants due to its small size.
Choice B rationale
The vastus lateralis muscle is one of the preferred sites for intramuscular injections in infants, including the vitamin K injection. This muscle is large enough to absorb the medication, and injections here carry less risk of hitting a nerve or blood vessel.
Choice C rationale
The ventrogluteal muscle is not typically used for intramuscular injections in infants. This site is often used in older children and adults.
Choice D rationale
The dorsogluteal site is not recommended for intramuscular injections due to the risk of damaging the sciatic nerve.
