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 D
Explanation
Choice A rationale:
Increased pancreatic activity during pregnancy causing fat intolerance is not related to the cause of indigestion and heartburn. Pancreatic activity can change during pregnancy, but it does not directly impact indigestion and heartburn.
Choice B rationale:
Increased estrogen production causing more hydrochloric acid in the stomach is not the cause of indigestion and heartburn during pregnancy. While hormones can influence digestion, the mechanism for indigestion and heartburn lies elsewhere.
Choice C rationale:
Pressure from the growing uterus pushing up on the stomach and intestines is a contributing factor to indigestion and heartburn during pregnancy. However, it is not the primary cause. The main cause is related to the relaxation of the cardiac sphincter.
Choice D rationale:
Progesterone causes relaxation of the cardiac sphincter, which is a muscular valve that prevents stomach acid from flowing back into the esophagus. When this sphincter relaxes, it can lead to acid reflux and subsequent indigestion and heartburn during pregnancy. The nurse should educate the client about this hormonal effect to help manage these symptoms effectively.
Correct Answer is A
Explanation
Choice A rationale:
Petroleum jelly is a common recommendation to apply during diaper changes for circumcised newborns. It acts as a barrier between the diaper and the healing penis, reducing friction and preventing the diaper from sticking to the sensitive area. This can help promote better healing and prevent discomfort for the newborn.
Choice B rationale:
Pre-moistened towelettes are not typically recommended for application on the penis of a circumcised newborn during diaper changes. These towelettes may contain chemicals or irritants that could potentially irritate the delicate skin of the healing area.
Choice C rationale:
Povidone-iodine is an antiseptic solution often used to disinfect the skin before procedures or surgeries. However, it is not recommended for routine use on the penis of a circumcised newborn during diaper changes as it may be too harsh for the healing skin.
Choice D rationale:
Silver sulfadiazine is a topical antimicrobial agent used for treating burns and certain infections. However, it is not indicated for use on a circumcised newborn's penis during diaper changes. The healing process after circumcision does not usually involve infections that require this type of treatment.
