Ketamine anesthesia is associated with:

Correct Answer: D

Rationale: The correct answer is D because ketamine anesthesia is associated with cardiovascular stimulation due to its sympathomimetic effects. It also increases cerebral blood flow, oxygen consumption, and intracranial pressure. Additionally, disorientation, sensory and perceptual illusions, and vivid dreams can occur post-anesthesia due to its psychotomimetic properties. Choices A, B, and C individually do not fully encompass the range of effects associated with ketamine anesthesia, making D the correct choice.

Correct Answer: C

Rationale: Aglycone is essential for cardiotonic action because it refers to the non-sugar component of a glycoside molecule that possesses pharmacological activity. In cardiotonic action, the aglycone part of the glycoside compound is responsible for the therapeutic effect on the heart, making choice C the correct answer. Plasma protein binding (choice A), half-life (choice B), and metabolism (choice D) do not directly involve the aglycone component in the context of this question.

Correct Answer: D

Rationale: The correct answer is D: Sustac. Sustac is a long-acting nitrate drug that provides sustained release of nitroglycerin, leading to prolonged vasodilation effects. This is achieved through its formulation that allows for controlled and gradual release of the medication over an extended period of time. In contrast, options A, B, and C are short-acting nitrate drugs that are rapidly absorbed and have a shorter duration of action, making them unsuitable for long-term management of conditions requiring sustained vasodilation.

Correct Answer: A

Rationale: The correct answer is A: Noradrenalin. Noradrenalin is a sympathomimetic drug that acts on alpha and beta adrenergic receptors, leading to increased cardiac output by increasing heart rate and contractility. Methyldopa (B) and Phenylephrine (C) are vasoconstrictors that can increase blood pressure but not cardiac output. Angiotensinamide (D) is not a drug commonly used to increase cardiac output.

Correct Answer: C

Rationale: The correct answer is C: Triiodothyronine. The thyroid gland produces triiodothyronine (T3) along with its precursor hormone, thyroxine (T4), which are essential for regulating metabolism in the body. T3 is the active form of thyroid hormone that influences various physiological processes. Thyroid-stimulating hormone (TSH) is produced by the pituitary gland to stimulate the thyroid gland to produce T3 and T4, making choice A incorrect. Thyrotropin-releasing hormone (TRH) is produced by the hypothalamus to stimulate the pituitary gland to produce TSH, making choice B incorrect. Thyroglobulin is a protein synthesized by the thyroid gland to store thyroid hormones, not a hormone itself, making choice D incorrect.
