Cardiovascular Drugs Pharmacology Questions
Question 1 of 5
Which type of receptors can be activated by angiotensinamide:
Correct Answer: D
Rationale: Certainly! Angiotensinamide is a peptide derived from angiotensinogen that activates angiotensin receptors. Step 1: Angiotensinamide is a component of the renin-angiotensin system and binds specifically to angiotensin receptors. Step 2: Angiotensin receptors are a distinct class of receptors that respond to angiotensin peptides, including angiotensinamide. Therefore, the correct answer is D. Choices A, B, and C are incorrect because angiotensinamide does not activate adrenergic, cholinergic, or dopaminergic receptors, but rather specifically binds to angiotensin receptors.
Question 2 of 5
The normal ovary produces small amount of androgens including testosterone androstenedione and degydroepiandrosterone. This consideration is:
Correct Answer: A
Rationale: The correct answer is A because the normal ovary does indeed produce small amounts of androgens such as testosterone, androstenedione, and dehydroepiandrosterone. This is a well-established fact in endocrinology. Choice B is incorrect because it contradicts the established knowledge about hormone production in the ovary. Choice C is incorrect as it doesn't provide any relevant information to confirm or deny the statement in the question. Choice D is incorrect because not all of the statements are true. Only option A correctly reflects the fact that the normal ovary produces small amounts of androgens.
Question 3 of 5
Antibody is a protein substance produced in the blood or tissues in response to a specific antigen, such as a bacterium or a toxin that destroys or weakens bacteria and neutralizes organic poisons, thus forming the basis of immunity. This consideration is:
Correct Answer: A
Rationale: Rationale: 1. Antibodies are indeed protein substances produced in response to specific antigens. 2. Antibodies work by binding to antigens, marking them for destruction. 3. Antibodies play a crucial role in immune response and immunity. 4. Therefore, the statement accurately describes the role and function of antibodies. Summary: - Choice A is correct as it accurately describes the function of antibodies. - Choice B is incorrect as antibodies do play a role in immunity. - Choice C is incorrect as it implies all statements are true. - Choice D is incorrect as antibodies do exist and have a specific function.
Question 4 of 5
Immunomodulating agent is:
Correct Answer: D
Rationale: The correct answer is D because all three choices (Sirolimus, Levamisole, and Tacrolimus) are immunomodulating agents that work by modifying the immune response. Sirolimus inhibits T-cell activation, Levamisole enhances immune function, and Tacrolimus suppresses T-cell activation. Each agent targets specific components of the immune system to regulate the immune response. Therefore, the correct answer is D as all the listed options are immunomodulating agents. Choice A, Sirolimus, is an mTOR inhibitor used in immunosuppression. Choice B, Levamisole, is an immunostimulant used in treating parasitic infections. Choice C, Tacrolimus, is a calcineurin inhibitor used in immunosuppression.
Question 5 of 5
Which of the following antienzymes is a fibrinolysis inhibitor?
Correct Answer: C
Rationale: The correct answer is C: Aminocaproic acid. Aminocaproic acid is a known fibrinolysis inhibitor that works by preventing the breakdown of blood clots. It does this by inhibiting the activation of plasmin, the enzyme responsible for breaking down fibrin clots. Clavulanic acid and sulbactam are both beta-lactamase inhibitors used in combination with antibiotics to prevent bacterial resistance. Disulfiram is an alcohol deterrent used in the treatment of alcoholism and does not have any direct relation to fibrinolysis inhibition.
