A nurse is assisting with the monitoring of a client who is in the first stage of labor, with an external fetal monitor in place and IV fluids infusing. Which of the following factors will cause variable decelerations in the fetal heart rate?
Fetal head compression.
Umbilical cord compression.
Maternal opioid administration.
Uteroplacental insufficiency.
The Correct Answer is B
Choice A rationale:
Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.
Choice B rationale:
Umbilical cord compression is a known cause of variable decelerations in the fetal heart rate. When the umbilical cord is compressed, it can temporarily disrupt blood flow and oxygen supply to the fetus, leading to decelerations. Variable decelerations often appear as abrupt, sharp drops in the fetal heart rate and are typically characterized by their unpredictable
nature.
Choice C rationale:
Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.
Choice D rationale:
Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which can lead to late decelerations in the fetal heart rate, not variable decelerations.

Correct Answer is ["B","C"]
Explanation
Choice A rationale:
The nurse does not need to report the blood pressure finding. While blood pressure is an essential vital sign to monitor during pregnancy, the scenario does not indicate any abnormalities or concerning values in the client's blood pressure. Therefore, there is no immediate cause for reporting this finding.
Choice B rationale:
The nurse should report cerebral manifestations to the provider. The client's complaint of a more severe headache, rated at 5 on a 0 to 10 pain scale, along with feeling dizzy when getting up from the examination table, may indicate potential neurological symptoms. These could be signs of conditions like preeclampsia, which is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, including the brain.
Choice C rationale:
The nurse should also report fetal heart rate findings to the provider. The client reports occasional contractions and positive fetal movement, but there is no mention of fetal heart rate in the nurse's notes. Monitoring the fetal heart rate is crucial during prenatal care, as changes in fetal heart rate could indicate fetal distress or other complications.
Choice D rationale:
The nurse does not need to report respiratory rate findings. There is no indication in the nurse's notes of any respiratory issues or complaints from the client, making this finding less relevant to the current situation.
Choice E rationale:
The nurse does not need to report deep tendon reflexes in this context. Deep tendon reflexes are not typically a priority assessment during routine prenatal care unless there are specific concerns or indications of neurological issues.
Choice F rationale:
The nurse does not need to report gastrointestinal assessment findings based on the information provided in the scenario. While the client reports "heartburn,”. there are no other gastrointestinal symptoms or indications of acute gastrointestinal issues requiring immediate reporting.
Correct Answer is ["A","D","E"]
Explanation
Dysuria - Dysuria refers to painful or difficult urination. In a client with a urinary tract infection (UTI), this symptom is commonly present. The rationale behind this finding is that the infection irritates the urinary tract, causing discomfort and pain during urination. The client may experience a burning sensation or pressure while passing urine.
Choice D rationale
Hematuria - Hematuria refers to the presence of blood in the urine. In the case of a UTI, inflammation of the urinary tract can lead to tiny blood vessels rupturing, resulting in blood in the urine. This can cause the urine to appear pink, red, or brownish.
Choice E rationale:
Urinary frequency - Urinary frequency is another common symptom of a UTI. The infection can irritate the bladder lining, leading to an increased urge to urinate even when the bladder is not full. The client may feel the need to urinate frequently throughout the day and night.
Choice B rationale
Dependent edema - Dependent edema is not typically associated with a urinary tract infection. Edema is the accumulation of fluid in tissues, often causing swelling in the lower extremities due to gravity (dependent). This symptom is more commonly related to issues such as heart, kidney, or liver problems.
Choice C rationale
Polyuria - Polyuria refers to excessive urination, usually producing abnormally large volumes of urine. While frequent urination is a symptom of a UTI, polyuria, in this context, is not accurate. UTIs tend to cause frequent but smaller volumes of urine due to the irritation and inflammation of the bladder.
