Midwifery Exam Questions Questions
Question 1 of 5
The MAIN function of surfactant factor is to
Correct Answer: A
Rationale: The correct answer is A: Prevent alveoli of the lungs from collapsing. Surfactant reduces surface tension in the alveoli, preventing them from collapsing during exhalation and maintaining lung compliance. B, C, and D are incorrect because surfactant primarily affects lung mechanics, not the initiation of breathing, maturity of the respiratory center, or immediate regulation of breathing upon birth.
Question 2 of 5
What are the risks of untreated gestational hypertension?
Correct Answer: D
Rationale: The correct answer is D, All of the above. Untreated gestational hypertension can lead to serious complications such as preeclampsia, characterized by high blood pressure and organ damage, placental abruption which is the separation of the placenta from the uterine wall, and preterm labor, resulting in premature birth. Each of these complications poses significant risks to both the mother and the baby, highlighting the importance of managing gestational hypertension. Therefore, all the choices A, B, and C are consequences of untreated gestational hypertension.
Question 3 of 5
A patient with chronic hepatic encephalopathy is being discharged home. Discharge teaching centers upon long-term management strategies to prevent ammonia accumulation. Teaching for this patient includes instruction about
Correct Answer: C
Rationale: The correct answer is C: Protein intake of 50 g daily. In hepatic encephalopathy, reducing protein intake helps decrease ammonia production. Excessive ammonia leads to neurological symptoms. Lactulose (choice A) is correct for hepatic encephalopathy as it helps eliminate ammonia through the gut. Spironolactone (choice B) is a diuretic and not indicated for hepatic encephalopathy. Zolpidem (choice D) is a sleep aid and not relevant to managing ammonia accumulation. In summary, choice C is correct because it directly targets the underlying issue of ammonia accumulation in hepatic encephalopathy, while the other choices do not address this specific concern.
Question 4 of 5
A neonate of a smear-negative mother just before birth receives BCG as usual.
Correct Answer: A
Rationale: The correct answer is A: TRUE. This is because BCG vaccination for newborns is recommended even if the mother is smear-negative for tuberculosis, as it helps protect the newborn from severe forms of TB. Smear status of the mother does not impact the need for BCG vaccination in the neonate. Choice B is incorrect as it falsely implies that BCG should not be given in this scenario. Choices C and D are not applicable as they do not provide any information.
Question 5 of 5
The progression of coronary artery plaque formation can lead to a variety of pathologic conditions. When subtotal plaque disruption occurs resulting in vasoconstriction, platelet activation, and embolization, it most commonly causes which clinical phenomenon?
Correct Answer: C
Rationale: The correct answer is C: Transmural myocardial infarction. Subtotal plaque disruption leads to vasoconstriction, platelet activation, and embolization, causing complete occlusion of a coronary artery. This results in ischemia of the entire thickness of the myocardial wall, leading to transmural myocardial infarction. Endothelial cell dysfunction (A) is an early event in atherosclerosis but does not directly result from subtotal plaque disruption. Prinzmetal's angina (B) is caused by transient coronary artery spasm rather than plaque disruption. Non-ST elevation myocardial infarction (D) involves incomplete blockage of a coronary artery and typically does not result from subtotal plaque disruption.
