Midwifery Practice Questions Questions
Question 1 of 5
What is the most common cause of fetal distress during labor?
Correct Answer: C
Rationale: The correct answer is C: Placental insufficiency. Placental insufficiency can lead to decreased oxygen and nutrient supply to the fetus, causing fetal distress during labor. This can result in abnormal fetal heart rate patterns and potential complications. A: Umbilical cord prolapse can also cause fetal distress but is less common than placental insufficiency. B: Uterine rupture is a serious complication but typically presents with maternal symptoms rather than fetal distress. D: Fetal position can impact labor progress but is not typically the primary cause of fetal distress.
Question 2 of 5
What is the impact of maternal stress on fetal development?
Correct Answer: D
Rationale: The correct answer is D because maternal stress can indeed lead to low birth weight, increase the risk of preterm labor, and affect brain development in the fetus. Stress hormones can interfere with the placental function, affecting the transfer of nutrients to the fetus and leading to low birth weight. Stress can also trigger early contractions, potentially resulting in preterm labor. Furthermore, maternal stress can impact fetal brain development through the release of stress hormones that can alter the development of the fetal brain structures. Therefore, all of the choices (A, B, and C) are correct in demonstrating the impact of maternal stress on fetal development.
Question 3 of 5
Ms. Kweke’s possible complications (obstructed labour):
Correct Answer: D
Rationale: Rationale: 1. Obstructed labor can lead to prolonged pressure on the uterus, causing hemorrhage and uterine rupture (A). 2. Prolonged labor can result in fetal distress due to reduced oxygen supply and potential infection (B). 3. Therefore, both complications mentioned in A and B can occur in obstructed labor. Summary: A: Incorrect - Preterm birth and asphyxia are not directly related to obstructed labor. B: Incorrect - Only fetal distress and infection are commonly associated with obstructed labor. C: Incorrect - Both A and B are possible complications of obstructed labor, making D the correct choice.
Question 4 of 5
Five (5) major factors predisposed to uterine rupture:
Correct Answer: A
Rationale: Rationale for Correct Answer (A): 1. Previous C-section and uterine scars weaken the uterine wall. 2. Fetal macrosomia (large baby) increases pressure on the uterus. 3. Trauma can cause direct injury to the uterus. 4. Prolonged labor can lead to uterine overdistension and fatigue, increasing rupture risk. Summary of Incorrect Choices: B: Malpresentation, premature rupture of membranes, obesity, malnutrition, anemia are not direct factors for uterine rupture. C: Uterine fibroids, excessive weight gain, smoking, poor prenatal care can contribute to complications but not primary causes of uterine rupture. D: Not all factors in choices B and C are predisposing factors for uterine rupture, making this choice incorrect.
Question 5 of 5
A patient with suspected Cushings syndrome is being evaluated to establish the diagnosis and cause. Patients with an adrenal tumor typically will demonstrate
Correct Answer: A
Rationale: The correct answer is A (Low ACTH and low cortisol) because in patients with an adrenal tumor causing Cushing's syndrome, the tumor autonomously produces cortisol, leading to suppression of ACTH secretion from the pituitary. This results in low ACTH levels and high cortisol levels. Choices B, C, and D are incorrect because they do not reflect the characteristic hormone levels seen in patients with an adrenal tumor causing Cushing's syndrome.
