Midwifery Practice Questions

Correct Answer: B

Rationale: The correct answer is B: Inadequate surfactant levels. Surfactant is a substance that reduces surface tension in the alveoli, preventing their collapse. In respiratory distress syndrome, premature infants have insufficient surfactant production, leading to collapsed alveoli and difficulty breathing. Choice A is incorrect because it focuses on quality rather than quantity of surfactant. Choice C is incorrect as rib cage underdevelopment is associated with congenital conditions like thoracic dystrophy, not RDS. Choice D is incorrect as gradual alveolar rupture is not a known cause of RDS.

Correct Answer: C

Rationale: The correct answer is C: Choanal atresia. The congenital abnormality of the respiratory tract with abnormal apical position is typically associated with choanal atresia, which is a blockage or narrowing of the back of the nasal passage. This condition can lead to respiratory distress in newborns due to difficulty breathing through the nose. Explanation: 1. Laryngeal stridor (Choice A) is a high-pitched noise during breathing and is not typically associated with abnormal apical position. 2. Diaphragmatic hernia (Choice B) is a defect in the diaphragm that allows abdominal organs to move into the chest cavity, but it is not related to abnormal apical position. 3. Tracheo-bronchi fistula (Choice D) is an abnormal connection between the trachea and bronchi, which is not associated with abnormal apical position. In summary, choanal atresia is the correct answer because it fits the description of

Correct Answer: A

Rationale: The correct answer is A. High-dose initial steroids are tapered off over a period of 4 to 6 weeks posttransplant. This is because corticosteroids are used initially to prevent rejection and then gradually tapered to minimize side effects. Choice B is incorrect as it states a general interest but does not address the specific protocol for corticosteroid use. Choice C is incorrect as there is no evidence suggesting better results in corticosteroid-free protocols for second-transplant recipients. Choice D is incorrect as there is no strong evidence supporting corticosteroid-free rejection protocols in posttransplant patients.

Correct Answer: A

Rationale: The correct answer is A: Irritable bowel syndrome. Mrs. Maroldo's history of recurrent left lower quadrant pain that usually resolves with antibiotics suggests a chronic condition rather than an acute one like diverticulitis, appendicitis, or inflammatory bowel disease. Her lack of nausea, vomiting, and severe symptoms, along with the presence of diarrhea and no bowel movements, align more with irritable bowel syndrome. Additionally, her vital signs are not significantly elevated, ruling out acute conditions like appendicitis. Discomfort to deep palpation in the left lower quadrant is common in irritable bowel syndrome due to visceral hypersensitivity. Therefore, based on her chronic symptoms, lack of severe signs, and typical presentation, the most likely diagnosis is irritable bowel syndrome.

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.
