A nurse caring for a patient in labor is evaluating the fetal heart monitor.Which finding would indicate fetal distress?

The fetal heart rate decreases after the start of a contraction and returns to the baseline 60 seconds after the end of the contraction.

There is a six to ten beat-to-beat variability in the fetal heart rate.

The fetal heart rate accelerates five to seven beats just prior to the beginning of a contraction.

The fetal heart rate decreases at the start of the contraction and returns to baseline by the end of the contraction.

Answer and Explanation

The Correct Answer is A

The correct answer is choice A and it indicates fetal distress because it is a sign of late deceleration. Late decelerations are due to uteroplacental insufficiency as the result of decreased blood flow and oxygen to the fetus during the uterine contractions. This causes hypoxemia and can lead to fetal acidosis and neurological damage.

Choice B is wrong because it indicates a normal variability in the fetal heart rate, which reflects a healthy autonomic nervous system. A normal fetal heart rate is 120-160 beats per minute.

Choice C is wrong because it indicates an early acceleration in the fetal heart rate, which is a benign finding that may occur with fetal movement or stimulation.

Choice D is wrong because it indicates an early deceleration in the fetal heart rate, which is a normal response to fetal head compression during contractions.

It does not indicate fetal distress.

Normal ranges for fetal heart rate patterns are:

• Baseline: 120-160 beats per minute

• Variability: 6-25 beats per minute

• Accelerations: at least 15 beats per minute above baseline for at least 15 seconds

• Decelerations: none or early (mirror contractions)

Correct Answer is B

Explanation

The correct answer is choice B. Position the patient in a left lateral position.This is because late fetal decelerations indicate uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen to the fetus.By positioning the patient on her left side, the blood flow to the placenta and the fetus is improved.

Choice A is wrong because notifying the health care provider is not the first action that the nurse should take.The nurse should first intervene to correct the cause of fetal distress and then inform the provider.

Choice C is wrong because increasing the patient’s intravenous rate may not help with uteroplacental insufficiency.It may also cause fluid overload or pulmonary edema in the patient.

Choice D is wrong because providing the patient with oxygen via a face mask is not the most effective way to increase fetal oxygenation.Oxygen therapy may be used as an adjunct to other interventions, but it is not sufficient by itself.

A. Insulin amount needs will remain stable during the third trimester. B. Insulin amount needs will continue to increase throughout the second and third trimesters. C. Insulin amount needs will decrease during the third trimester. D. Insulin amount needs will remain stable for the rest of the second and during the third trimesters.

Correct Answer is B

Explanation

The correct answer is choice B. Insulin amount needs will continue to increase throughout the second and third trimesters.This is because gestational diabetes is a form of diabetes that develops during pregnancy, usually during the 2nd or 3rd trimester.It is caused by hormonal changes that interfere with the action of insulin, leading to high blood sugar levels.As the pregnancy progresses, the placenta produces more hormones that increase insulin resistance, so the mother needs more insulin to keep her blood sugar within normal range.

Choice A is wrong because insulin amount needs will not remain stable during the third trimester.They will increase as the placenta grows and produces more hormones that cause insulin resistance.

Choice C is wrong because insulin amount needs will not decrease during the third trimester.They will increase as the placenta grows and produces more hormones that cause insulin resistance.

Choice D is wrong because insulin amount needs will not remain stable for the rest of the second and during the third trimesters.They will increase as the pregnancy progresses and the placenta produces more hormones that increase insulin resistance.

Normal ranges for blood sugar during pregnancy are: fasting < 95 mg/dL, 1 hour after meal < 140 mg/dL, 2 hours after meal < 120 mg/dL.
