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: B

Rationale: The correct answer is B: Facilitation of weight gain. A thermal controlled environment for a low birth weight baby helps in maintaining the baby's body temperature, reducing energy expenditure, and promoting weight gain. This is crucial for the baby's growth and development.

Incorrect choices:
A: Prevention of infection - While a thermal controlled environment can indirectly help prevent infections by maintaining the baby's health, it is not the primary aim.
C: Provision of quality care - Quality care involves multiple aspects beyond just thermal control, so this is not the primary aim.
D: Provision of nutrition - Nutrition is important for weight gain, but the thermal controlled environment specifically focuses on regulating the baby's body temperature to support weight gain.

Correct Answer: A

Rationale: The correct answer is A (36 weeks gestation) because at this stage, the fetal lie should stabilize into a consistent position, typically longitudinal. Before 36 weeks, fetal movement and position can vary frequently.

Choices B, C, and D are incorrect as they are past the point where fetal lie should have stabilized. At 42 weeks gestation (
Choice
B), the baby is considered post-term, and fetal lie should have already been established. Similarly,

Choices C (38 weeks) and D (40 weeks) fall within the expected range for fetal lie stabilization.

Correct Answer: D

Rationale: The use of bed cradle in leg thrombosis management is to promote venous drainage. Elevating the legs on a bed cradle helps improve blood flow back to the heart, reducing swelling and preventing blood clots. Keeping the legs straight (
A) is not the main purpose. Preventing embolism (
B) is important but not the direct purpose of a bed cradle. Controlling body temperature (
C) is unrelated to the use of a bed cradle for leg thrombosis.

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.
