General contraindications for anticancer drugs are:

Correct Answer: D

Rationale: The correct answer is D: All of the above. General contraindications for anticancer drugs include depression of bone marrow, which can lead to decreased production of blood cells; acute infections, as these drugs can further compromise the immune system; and severe hepatic and/or renal insufficiency, as these organs are responsible for drug metabolism and elimination. These contraindications are crucial to consider to prevent further harm to the patient. Choices A, B, and C individually are incorrect because they do not encompass all the general contraindications associated with anticancer drugs.

Correct Answer: C

Rationale: The correct answer is C: Blockade of beta receptors of the vascular wall. Atenolol is a beta-blocker that works by blocking beta receptors in the vascular wall, leading to reduced sympathetic stimulation and vasodilation, ultimately lowering blood pressure. Choice A is incorrect as atenolol primarily affects beta receptors, not large veins. Choice B is incorrect as atenolol does not directly affect epinephrine release from the adrenal medulla. Choice D is incorrect as atenolol primarily acts at the beta receptors in the vascular wall rather than affecting sympathetic outflow from the vasomotor area.
