A nurse is caring for a client who is in active labor. The nurse notes early decelerations of the FHR on the fetal monitor tracing. The nurse should identify that which of the following conditions causes early decelerations in the FHR?
Fetal hypoxemia.
Cord compression.
Uteroplacental insufficiency.
Head compression.
The Correct Answer is D
Choice A rationale:
Fetal hypoxemia is associated with late decelerations in the fetal heart rate (FHR) tracing. It occurs when the fetus experiences a decreased supply of oxygen, typically due to placental insufficiency or maternal hypotension.
Choice B rationale:
Cord compression can lead to variable decelerations in the FHR tracing. It occurs when the umbilical cord is compressed, restricting blood flow to the fetus temporarily.
Choice C rationale:
Uteroplacental insufficiency causes late decelerations in the FHR tracing. It refers to an inadequate blood flow between the uterus and placenta, resulting in reduced oxygen supply to the fetus.
Choice D rationale:
Head compression is the correct answer for early decelerations in the FHR tracing. It happens during contractions when the fetal head is compressed by the maternal pelvis, leading to a temporary vagal response that slows the heart rate.

Correct Answer is B
Explanation
Choice A rationale:
Hyporeactivity, or reduced responsiveness to stimuli, is not typically associated with neonatal abstinence syndrome (NAS) NAS is characterized by increased irritability and not reduced activity.
Choice B rationale:
An excessive high-pitched cry is a common manifestation of neonatal abstinence syndrome. Infants exposed to substances like methadone during pregnancy may experience heightened sensitivity and exhibit a high-pitched cry as a sign of withdrawal.
Choice C rationale:
Acrocyanosis, a bluish discoloration of the hands and feet, is not a specific indicator of neonatal abstinence syndrome. It is a common finding in newborns and often resolves on its own.
Choice D rationale:
A respiratory rate of 50/min is within the normal range for a newborn. It is not an indication of neonatal abstinence syndrome.
Correct Answer is C
Explanation
Choice A rationale:
Raloxifene is not used to treat migraines. It is a selective estrogen receptor modulator (SERM) that primarily acts on bone tissues, estrogen receptors, and has anti-estrogenic effects in the breast, which may reduce the risk of breast cancer.
Choice B rationale:
Raloxifene is not used to treat hypertension (high blood pressure) It is primarily indicated for the prevention and treatment of osteoporosis in postmenopausal women.
Choice C rationale:
This is the correct choice. Raloxifene is indicated for the treatment and prevention of osteoporosis in postmenopausal women. It helps increase bone density and reduces the risk of fractures associated with osteoporosis.
Choice D rationale:
Raloxifene is not used to treat heart disease. While it may have some cardiovascular benefits due to its effects on cholesterol levels, it is not a primary medication for heart disease management.
