Correct Answer: A

Rationale: The correct answer is A: Glucocorticoids and androgens. The adrenal cortex is divided into three layers, with the outer layer responsible for producing mineralocorticoids like aldosterone, the middle layer producing glucocorticoids like cortisol, and the inner layer producing androgens. Glucocorticoids are essential for regulating metabolism and immune response, while androgens are male sex hormones. Choices B, C, and D are incorrect because mineralocorticoids, catecholamines, norepinephrine, and epinephrine are produced by different parts of the adrenal gland, not specifically by the adrenal cortex.

Correct Answer: B

Rationale: The correct answer is B: Lifetime dependency on hormone replacement. After hypophysectomy, the pituitary gland is removed, leading to a deficiency in essential hormones. Patients will need lifelong hormone replacement therapy to maintain normal body functions. This is crucial for regulating metabolism, growth, reproduction, and stress response. Choices A, C, and D are incorrect because abnormal distribution of body hair, increased fluid intake, and repeat surgical procedures are not typically associated with hypophysectomy. It is essential to focus on the long-term management of hormone replacement therapy to ensure the patient's overall health and well-being.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be measured or observed directly. In this case, nausea and abdominal pain are symptoms that can only be described by the patient, making them subjective data. Vomiting, pulse rate, respirations, blood pressure, pale skin, and thick toenails are all objective data, as they can be measured or observed directly by the healthcare provider. Therefore, choice C is the correct answer as it represents subjective data.

Correct Answer: C

Rationale: The correct answer is C: A decreased number of functioning acetyl-choline receptor sites. This is because in diseases like myasthenia gravis, there is an autoimmune attack on acetylcholine receptor sites, leading to decreased functionality. Choice A is incorrect because it refers to a genetic defect in acetylcholine production, which is not typically the cause of myasthenia gravis. Choice B is incorrect as it suggests a reduced amount of acetylcholine, which is not the primary issue in myasthenia gravis. Choice D is incorrect as it mentions inhibition of the enzyme Ache, which is not the main mechanism in this disease.

Correct Answer: A

Rationale: The correct answer is A: Increased ICP. Decreasing level of consciousness is a classic sign of increased intracranial pressure (ICP) due to the compression of the brain. As ICP rises, it impairs cerebral perfusion leading to altered mental status. Parasympathetic response (B) and sympathetic response (C) are related to autonomic nervous system functions, not consciousness. Increased cerebral blood flow (D) might lead to conditions like hyperemia but does not directly cause a decreased level of consciousness.
