Indications of thyroid hormones are following EXCEPT:

Correct Answer: D

Rationale: The correct answer is D: For treatment of simple obesity. Thyroid hormones are not indicated for the treatment of simple obesity as they do not directly affect weight loss. A: Cretinism - Thyroid hormones are indicated for the treatment of cretinism, a condition caused by thyroid hormone deficiency in infancy. B: Myxoedema - Thyroid hormones are indicated for the treatment of myxoedema, a severe form of hypothyroidism in adults. C: Hashimoto's disease - Thyroid hormones are indicated for the treatment of Hashimoto's disease, an autoimmune condition that leads to hypothyroidism. In summary, thyroid hormones are indicated for conditions related to thyroid hormone deficiencies and dysfunctions, but not for the treatment of simple obesity.

Correct Answer: A

Rationale: The correct answer is A. Allergic reaction is a response of the immune system to an allergen that the body has previously been sensitized to. This response can be local or generalized, involving various symptoms such as itching, hives, swelling, and in severe cases, anaphylaxis. Choice B describes inflammation, not specifically related to allergies. Choices C and D are unrelated medications. In summary, choice A is correct because it accurately defines an allergic reaction, while the other choices do not specifically address the nature of allergies.

Correct Answer: A

Rationale: The correct answer is A because vitamin-like compounds are a group of compounds that are essential for health but are not classified as vitamins. These compounds have specific roles in the body, particularly during periods of rapid growth and development. They are not inorganic nutrients (B) or organic substances needed in large quantities (C). They are also not products of endocrine gland secretion (D). The key is to understand that vitamin-like compounds are essential for certain stages of development and growth, making choice A the most appropriate answer.

Correct Answer: B

Rationale: Selegiline is the correct answer as it is a monoamine oxidase (MAO) inhibitor. MAO inhibitors block the breakdown of monoamine neurotransmitters such as dopamine, serotonin, and norepinephrine. Physostigmine is an acetylcholinesterase inhibitor, not an MAO inhibitor. Acetazolamide is a carbonic anhydrase inhibitor used in glaucoma and altitude sickness. Disulfiram is an aldehyde dehydrogenase inhibitor used in alcohol aversion therapy.

Correct Answer: D

Rationale: Gemfibrozil (Lopid) increases lipoprotein lipase (LPL) activity in adipose tissue. Firstly, it is a fibric acid derivative that specifically targets LPL, leading to increased breakdown of triglyceride-rich lipoproteins. This mechanism helps lower triglyceride levels in the blood. Cholestyramine (A) is a bile acid sequestrant that does not affect LPL activity. Lovastatin (B) is a statin that primarily works by inhibiting cholesterol synthesis in the liver. Nicotinic acid (C) mainly acts by reducing circulating levels of LDL cholesterol and triglycerides, not by enhancing LPL activity.
