Correct Answer: B

Rationale: The correct answer is B: Turtle sign. This occurs when the fetal head retracts against the perineum during delivery, resembling a turtle retracting into its shell. This indicates fetal shoulder dystocia, a serious complication. Gaskin sign (A) refers to the position of the mother during labor. Klumpke sign (C) is related to brachial plexus injuries during delivery. Chignon sign (D) is not a recognized term in obstetrics.

Correct Answer: A

Rationale: Neonatal injury to nerve roots C8 & T1 leads to Klumpke's palsy due to damage to the lower brachial plexus. This results in weakness of the hand and forearm muscles. Erb's palsy is from injury to C5-C6 roots causing upper brachial plexus damage. Phrenic injury affects the diaphragm due to C3-C5 roots. Radial palsy involves the radial nerve, typically from injury at the spiral groove of the humerus. Therefore, the correct answer is A as it directly correlates with the specific nerve roots affected in Klumpke's palsy.

Correct Answer: C

Rationale: The correct answer is C: Importance of early ambulation. After a cesarean section, early ambulation is crucial to prevent complications like blood clots and promote circulation. It helps prevent post-operative complications. Choice A is important for respiratory health but not the priority right after surgery. Choice B focuses on perineal care which is important but not the immediate priority. Choice D is important, but recognizing signs of infection can wait until the client is more stable. Early ambulation is key to preventing complications and aiding in recovery.

Correct Answer: D

Rationale: The correct answer is D because hypoplastic left heart syndrome involves underdevelopment of the left ventricle, aortic valve, and aortic arch. The left ventricle is typically small and unable to adequately pump blood to the body. The aortic valve is often malformed, leading to difficulties in blood flow from the heart to the body. Additionally, the aortic arch may be narrow or underdeveloped, further impacting blood circulation. Choice A is incorrect as it includes the pulmonary veins, which are not typically affected in hypoplastic left heart syndrome. Choice B is incorrect as it focuses on the left atrium and pulmonary vessels, which are not the primary structures affected in this condition. Choice C is incorrect as it mentions the aorta arch, venacava, and right atrium, which are not primarily associated with hypoplastic left heart syndrome.

Correct Answer: A

Rationale: Placenta praevia is classified into four types based on the degree of coverage of the cervix by the placenta. Complete placenta praevia, where the internal os is completely covered by the placenta, is referred to as Type 4. This is the correct answer as it accurately describes the specific condition. Choices B, C, and D are incorrect as they do not correspond to the classification system for placenta praevia.
