Chapter 25 Cardiovascular Drugs Quizlet Questions
Question 1 of 5
Industrial solvent inhalation causes:
Correct Answer: D
Rationale: The correct answer is D because industrial solvent inhalation can cause quick intoxication due to the rapid absorption into the bloodstream, euphoria and a relaxed feeling due to the effects on the central nervous system, disorientation, slow passage of time, and hallucinations due to the impact on brain function. Choices A, B, and C all reflect different aspects of the effects of industrial solvent inhalation on the body and mind, making them incorrect individually. The combination of these effects, as stated in option D, accurately represents the comprehensive impact of inhalation of industrial solvents.
Question 2 of 5
Tick the drug used in aplastic anemia:
Correct Answer: C
Rationale: The correct answer is C: Epoetin alpha. Epoetin alpha is used in aplastic anemia to stimulate the production of red blood cells. In this condition, the bone marrow fails to produce enough blood cells. Epoetin alpha works by mimicking the action of erythropoietin, a hormone that stimulates red blood cell production. Now, let's analyze the other choices: A: Fercoven - This is not a drug commonly used in the treatment of aplastic anemia. B: Cyanocobalamin - This is a form of vitamin B12 and is not typically used to treat aplastic anemia. D: Folic acid - While folic acid may be used in certain types of anemia, it is not the primary drug used in the treatment of aplastic anemia. In summary, Epoetin alpha is the correct choice as it directly addresses the underlying issue of inadequate red blood cell production in aplastic an
Question 3 of 5
All of the following statements concerning the use of angiotensin-converting enzyme (ACE) inhibitors in the treatment of heart failure are true EXCEPT:
Correct Answer: B
Rationale: The correct answer is B. ACE inhibitors do not increase plasma cholesterol levels. ACE inhibitors improve hemodynamics by decreasing afterload, slow the progression of heart failure by preventing myocardial remodeling, and reduce secretion of aldosterone. Choice A is correct because ACE inhibitors reduce systemic vascular resistance, decreasing afterload. Choice C is correct because ACE inhibitors can prevent myocardial remodeling and slow the progression of heart failure. Choice D is correct because ACE inhibitors can reduce aldosterone secretion, leading to decreased sodium and water retention. Therefore, the incorrect statement among the choices is B.
Question 4 of 5
This drug reduces blood pressure by acting on vasomotor centers in the CNS:
Correct Answer: B
Rationale: The correct answer is B: Clonidine. Clonidine acts on vasomotor centers in the central nervous system (CNS) by stimulating alpha-2 adrenergic receptors, leading to decreased sympathetic outflow, resulting in reduced peripheral vascular resistance and ultimately lowering blood pressure. Labetalol (A) is a non-selective beta and alpha blocker, Enalapril (C) is an ACE inhibitor, and Nifedipine (D) is a calcium channel blocker, all of which work by different mechanisms to reduce blood pressure compared to Clonidine.
Question 5 of 5
What is the main action of GABA derivatives in disorders of brain circulation?
Correct Answer: B
Rationale: The correct answer is B: Stimulation of the metabolic processes in neurons. GABA derivatives act by enhancing neuronal metabolism, which helps improve brain circulation and function. This action supports the neurons' energy production and overall function. A: Decrease of vessel permeability is incorrect because GABA derivatives do not directly affect vessel permeability in brain circulation disorders. C: Brain vessel constriction is incorrect as GABA derivatives do not cause constriction of brain vessels but rather support neuronal function. D: Intracranial pressure increase is incorrect as GABA derivatives do not lead to an increase in intracranial pressure; instead, they support neuronal metabolic processes.
