Cardiovascular Drugs Commonly Prescribed Quizlet Questions
Question 1 of 5
Psychotropic medications can cause a parasympathetic and/or sympathetic response from the autonomic nervous system. Which of the following is considered a sympathetic response?
Correct Answer: A
Rationale: The correct answer is A: Pupil dilation. Sympathetic response involves the activation of the fight-or-flight response, leading to physiological changes to prepare the body for action. Pupil dilation occurs in response to sympathetic stimulation to enhance visual acuity. Increased saliva production (B) is a parasympathetic response for digestion. Decreased heart rate (C) and constricted airway (D) are both parasympathetic responses, as they are associated with relaxation and rest.
Question 2 of 5
A 50-year-old man who has been taking phenobarbital for 1 week is found very lethargic and unable to walk after eating out for dinner. His wife states that he has no other prescriptions and that he did not take an overdose—the correct number of pills is in the bottle. The nurse suspects that which of the following may have happened?
Correct Answer: B
Rationale: The correct answer is B: He drank a glass of wine. Phenobarbital is a central nervous system depressant, and when combined with alcohol, it can enhance the sedative effects, leading to extreme lethargy and impaired motor skills. This interaction can be dangerous and life-threatening. Incorrect choices: A: Taking a multivitamin would not cause such severe symptoms when combined with phenobarbital. C: Aspirin does not typically interact in a significant way with phenobarbital to cause extreme lethargy and inability to walk. D: Developing an allergy to the drug would result in different symptoms, such as rash, swelling, or difficulty breathing, rather than extreme lethargy and impaired motor skills.
Question 3 of 5
The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication?
Correct Answer: D
Rationale: Step 1: Nitroglycerin is light-sensitive and can degrade when exposed to light. PVC plastic can release compounds that can interact with nitroglycerin. Therefore, non-PVC plastic must be used to prevent drug degradation. Step 2: Using non-PVC bags and tubing ensures the drug's stability and efficacy during administration, reducing the risk of adverse effects. Step 3: This requirement is specific to intravenous nitroglycerin administration and is crucial to ensure the patient receives the intended therapeutic benefits without compromising the drug's potency. In summary, choice D is correct because using non-PVC plastic intravenous bags and tubing is essential to maintain the stability and effectiveness of intravenous nitroglycerin. Choices A, B, and C are incorrect as they do not address the specific requirement related to the administration of this medication.
Question 4 of 5
When reviewing patients’ histories, the nurse recognizes that which patient would be a likely candidate for drug therapy for cholesterol reduction?
Correct Answer: C
Rationale: Rationale: 1. Patient C has coronary heart disease, indicating a higher risk of cardiovascular events. 2. The LDL level of 165 mg/dL is above the recommended target for patients with coronary heart disease. 3. Lowering cholesterol levels in patients with existing heart disease is crucial to reduce the risk of further complications. Summary: A: LDL level is within the recommended range for patients with coronary heart disease. B: LDL level is high, but the absence of coronary heart disease makes this patient less of a priority. D: Although the LDL level is optimal, having coronary heart disease takes precedence over the number of risk factors.
Question 5 of 5
A patient has been taking iron supplements for anemia for 2 months. During a follow-up assessment, the nurse will observe for which therapeutic response?
Correct Answer: B
Rationale: The correct answer is B: Increased activity tolerance. Iron supplements help increase red blood cell production, improving oxygen delivery to tissues and reducing fatigue. Increased activity tolerance is a common therapeutic response to iron supplementation. Decreased weight (A) is not a direct therapeutic response to iron supplementation. Decreased palpitations (C) may improve with increased iron levels, but it is not the primary expected outcome. Increased appetite (D) is not a typical response to iron supplementation and may not be directly related to improved anemia symptoms.
