Intrapartum Complication Questions
Question 1 of 5
Observation of a fetal heart rate pattern indicates an increase in heart rate from the prior baseline rate of 152 bpm. Which physiologic mechanisms would account for this situation?
Correct Answer: D
Rationale: The correct answer is D: Sympathetic stimulation. Sympathetic stimulation increases heart rate by releasing norepinephrine, which acts on beta-adrenergic receptors in the heart. This leads to an increase in heart rate. Choices A and B are incorrect because inhibition of epinephrine or norepinephrine would not cause an increase in heart rate. Choice C is incorrect because stimulation of the vagus nerve would actually decrease heart rate by releasing acetylcholine, which acts on muscarinic receptors in the heart.
Question 2 of 5
When a pattern of variable decelerations occur, the nurse should immediately
Correct Answer: D
Rationale: The correct answer is D because positioning the patient in a knee-chest position helps to relieve pressure on the vena cava, improving blood flow to the placenta and fetus. This can help alleviate variable decelerations. Choice A is incorrect because administering oxygen at 8 to 10 L/min would not directly address the cause of variable decelerations. Choice B is incorrect as placing a wedge under the right hip is typically used for supine hypotension syndrome. Choice C is incorrect because increasing IV fluids may not directly address the issue of variable decelerations.
Question 3 of 5
Which medications could potentially cause hyperstimulation of the uterus during labor? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Oxytocin (Pitocin). Oxytocin is a uterotonic agent commonly used to induce or augment labor. It can cause hyperstimulation of the uterus, leading to uterine hypertonicity and potentially compromising fetal oxygenation. Misoprostol, Dinoprostone, and Methylergonovine maleate are not known to cause hyperstimulation of the uterus during labor.
Question 4 of 5
A new client is seen at the prenatal clinic and says she thinks she is pregnant. The first day of her last menstrual period was April 1, 2014. What is her EDB?
Correct Answer: A
Rationale: The correct answer is A: December 30, 2014. To calculate the Estimated Date of Birth (EDB), you add 9 months and 7 days to the first day of the last menstrual period. In this case, April 1, 2014 + 9 months is January 1, 2015, and then adding 7 days gives December 30, 2014 as the EDB. This calculation takes into account the typical 40-week gestational period of a pregnancy. Choices B, C, and D are incorrect because they do not consider the full 40-week gestational period from the last menstrual period.
Question 5 of 5
A 20-year-old gravida 1 para 0 presents to the prenatal clinic with a chief complaint that she feels like she is pregnant. Which are presumptive signs of pregnancy? Select all that apply.
Correct Answer: A
Rationale: The correct answer is A: Linea nigra. Linea nigra is a presumptive sign of pregnancy, which refers to a dark line that appears on the abdomen. This sign is caused by hormonal changes during pregnancy. Breast tenderness (B) and leukorrhea (C) are actually probable signs of pregnancy, not presumptive signs. Chadwick's sign (D) is also a probable sign, not a presumptive sign. Presumptive signs are subjective symptoms reported by the patient and are not definitive indicators of pregnancy.
