Midwifery Practice Questions

Correct Answer: A

Rationale: The correct answer is A: Type A aortic aneurysm. Type A involves the ascending aorta, which is more critical due to proximity to the heart. Immediate surgical intervention is necessary to prevent catastrophic complications like aortic dissection or rupture. Choice B, Type B, usually involves the descending aorta and can often be managed through medical therapy initially. Choice C, Descending aneurysm, may not require immediate surgery unless symptomatic or rapidly expanding. Choice D, Symptomatic aneurysm, could refer to any type and would need further evaluation to determine the urgency of surgical intervention.

Correct Answer: C

Rationale: The correct answer is C: Local anesthesia, cleansing, and suture repair. 1. Local anesthesia is needed to minimize pain during the procedure. 2. Cleansing is crucial to remove contaminants and reduce the risk of infection. 3. Suture repair is necessary for a jagged laceration of this size to promote proper wound healing and minimize scarring. Summary of other choices: A: Antibiotic therapy is not routinely needed for clean lacerations, and covering alone may not provide adequate wound closure. B: While wound exploration for foreign bodies is important, it is not the immediate priority for this patient with an open, flapping laceration. D: While cleansing, covering, and tetanus prophylaxis are important, antibiotic therapy is not routinely needed for clean lacerations.

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.

Correct Answer: D

Rationale: The correct answer is D: All neonates need vitamin K for activation of thrombokinase. Vitamin K is essential for the synthesis of clotting factors in the liver, including thrombokinase, which plays a crucial role in blood clotting. In neonates, there is a deficiency of vitamin K due to limited transfer across the placenta and low levels in breast milk. Administering vitamin K at birth helps prevent hemorrhagic disease of the newborn. Choices A, B, and C are incorrect because vitamin K does not directly impact immunity, prevent jaundice, or promote normal gut bacteria growth in neonates.

Correct Answer: B

Rationale: Iron supplementation benefits pregnancy by correcting or preventing iron deficiency anemia in the mother. Anemia can lead to various complications for the mother and baby. Iron is essential for the production of hemoglobin, which carries oxygen to tissues. Therefore, by reducing anemia, iron supplementation ensures optimal oxygen delivery to both the mother and the developing fetus. This ultimately supports healthy pregnancy outcomes. Explanation for other choices: A: Iron supplementation does not directly increase fetal blood flow. C: While iron deficiency may increase the risk of miscarriage, iron supplementation alone does not prevent miscarriages. D: Iron is not directly involved in fetal bone growth, so iron supplementation does not enhance this aspect of fetal development.
