Indicate an antiemetic agent which is related to neuroleptics:

Correct Answer: D

Rationale: Step-by-step rationale: 1. Prochlorperazine is a typical antipsychotic that also has antiemetic properties due to its dopamine receptor blocking activity. 2. Neuroleptics, like prochlorperazine, target dopamine receptors in the brain to alleviate symptoms. 3. Metoclopramide works by enhancing motility in the upper GI tract and has no direct relation to neuroleptics. 4. Nabilone is a synthetic cannabinoid used as an antiemetic, not related to neuroleptics. 5. Tropisetron is a serotonin receptor antagonist used as an antiemetic, not related to neuroleptics. Summary: Prochlorperazine is the correct answer as it shares the mechanism of action with neuroleptics by targeting dopamine receptors. Metoclopramide, nabilone, and tropisetron do not have this direct relationship with neuroleptics.

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.

Correct Answer: D

Rationale: Progesterone is a hormone essential for pregnancy and menstrual cycle regulation. It is primarily secreted by the corpus luteum after ovulation. Ovarian follicles also produce progesterone during the menstrual cycle. Additionally, granulosa and theca cells in the ovaries contribute to progesterone production. Therefore, the correct answer is D, "All of the above," as all three options play a role in progesterone secretion. Choices A, B, and C individually are incorrect as they only represent specific sources of progesterone production.
