What is the best nursing intervention for a pregnant woman in her third trimester who complains of feeling faint, dizzy, and agitated while her vital signs are being assessed?
Have the patient stand up and retake her blood pressure.
Have the patient lie supine for 5 minutes and recheck her blood pressure on both arms.
Have the patient sit down and hold her arm in a dependent position.
Have the patient turn to her left side and recheck her blood pressure in 5 minutes.
The Correct Answer is D
Choice A reason: This is not a good intervention, as it may worsen the symptoms of faintness, dizziness, and agitation. Standing up can cause a sudden drop in blood pressure (orthostatic hypotension), which can reduce the blood flow to the brain and the fetus. This can cause lightheadedness, blurred vision, and loss of consciousness in the woman, as well as fetal distress or hypoxia.
Choice B reason: This is not a good intervention, as it may also worsen the symptoms of faintness, dizziness, and agitation. Lying supine can cause compression of the inferior vena cava (a large vein that returns blood to the heart) by the gravid uterus, which can reduce the cardiac output (the amount of blood pumped by the heart) and the blood pressure. This can cause nausea, sweating, and visual disturbances in the woman, as well as fetal distress or hypoxia.
Choice C reason: This is not a good intervention, as it may not improve the symptoms of faintness, dizziness, and agitation. Sitting down and holding the arm in a dependent position can lower the blood pressure in the arm, but not in the rest of the body. This can cause inaccurate readings of the blood pressure and delay the detection of hypotension or hypertension. This can also cause discomfort and pain in the arm due to impaired circulation.
Choice D reason: This is the best intervention, as it can relieve the symptoms of faintness, dizziness, and agitation by improving the blood flow to the brain and the fetus. Turning to the left side can reduce the pressure of the uterus on the inferior vena cava and increase the cardiac output and the blood pressure. This can also optimize the placental perfusion (the blood flow to the placenta) and the fetal oxygenation.

Correct Answer is D
Explanation
Choice A reason: Hypoinsulinemia is not a major neonatal complication of the infant of a diabetic mother. It is a condition of low insulin levels in the blood, which can cause hyperglycemia.
Choice B reason: Hypercalcemia is not a major neonatal complication of the infant of a diabetic mother. It is a condition of high calcium levels in the blood, which can cause muscle weakness, confusion, and kidney stones.
Choice C reason: Hypobilirubinemia is not a major neonatal complication of the infant of a diabetic mother. It is a condition of low bilirubin levels in the blood, which can cause pale skin and eyes.
Choice D reason: Hypoglycemia is a major neonatal complication of the infant of a diabetic mother. It is a condition of low blood sugar levels, which can cause seizures, lethargy, and brain damage.
Choice E reason: None of the above is not a correct answer. There is one major neonatal complication of the infant of a diabetic mother, which is hypoglycemia.
Correct Answer is B
Explanation
Choice A reason: Vibroacoustic stimulation is a technique that uses sound to stimulate the fetus and elicit a response. It is sometimes used in conjunction with the nonstress test (NST), not the CST. The NST measures the fetal heart rate (FHR) in response to fetal movement, while the CST measures the FHR in response to uterine contractions.
Choice B reason: A negative CST result means that the FHR does not show any late decelerations during at least three contractions in a 10-minute period. Late decelerations are decreases in the FHR that begin after the peak of a contraction and return to the baseline after the contraction ends. They indicate uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen and nutrients to the fetus. A negative CST result is reassuring and suggests that the fetus is well-oxygenated and can tolerate labor².
Choice C reason: The CST is not an invasive test, as it does not involve inserting any instruments or devices into the uterus or the fetus. However, it does require stimulating contractions, either by giving the pregnant woman oxytocin (a hormone that causes uterine contractions) or by having her rub her nipples (which also releases oxytocin). The contractions can be uncomfortable and may trigger preterm labor in some cases.
Choice D reason: The CST is not more effective than the NST if the membranes have already been ruptured. In fact, the CST is contraindicated (not recommended) in women who have ruptured membranes, as it can increase the risk of infection and bleeding. The NST is a safer and simpler alternative to the CST, as it does not require stimulating contractions. However, the NST may not be as reliable as the CST in detecting fetal compromise.
