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?

Choice A rationale:

Periodic tingling of fingers is a common symptom during pregnancy and is often related to hormonal changes and increased fluid retention. While it can be uncomfortable, it is not necessarily an indication of a potential prenatal complication.

Choice B rationale:

Absence of clonus is not an abnormal finding during pregnancy. Clonus is a series of involuntary muscle contractions and relaxations and is generally not expected during a routine assessment.

Choice C rationale:

Leg cramps are a common complaint during pregnancy and are usually caused by changes in calcium and magnesium levels. While they can be uncomfortable, they are not typically considered an indication of a potential prenatal complication.

Choice D rationale:

Blurred vision can be an indication of preeclampsia, a serious condition that can occur during pregnancy. Preeclampsia is characterized by high blood pressure and damage to organs, often affecting the eyes, kidneys, and liver. It is crucial for the nurse to recognize this symptom and promptly inform the healthcare provider for further evaluation and management.

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.
