Chapter 25 Cardiovascular Drugs Quizlet Questions
Question 1 of 5
The __________ constitute a class of drugs that are commonly prescribed for cardiac arrhythmias but also have been found to be effective treatment for social phobias.
Correct Answer: D
Rationale: The correct answer is D: Beta-blockers. Beta-blockers are commonly prescribed for cardiac arrhythmias due to their ability to block the effects of adrenaline on the heart. In the context of social phobias, beta-blockers can help reduce physical symptoms of anxiety such as rapid heart rate and trembling, making them an effective treatment option. A: Benzodiazepines are typically used to treat anxiety disorders, but they are not specifically known for treating social phobias. B: Tricyclics are a class of antidepressants and are not commonly prescribed for social phobias. C: Azaspirones are anxiolytic drugs used to treat generalized anxiety disorder and are not commonly used for social phobias.
Question 2 of 5
A patient is taking flurazepam (Dalmane) 3 to 4 nights a week for sleeplessness. She is concerned that she cannot get to sleep without taking the medication. What nonpharmacologic measures should the nurse suggest to promote sleep for this patient?
Correct Answer: A
Rationale: The correct answer is A: Providing a quiet environment. Creating a quiet environment can help the patient relax and reduce distractions, promoting better sleep. This measure is important as it can help the patient establish a consistent sleep routine and reduce the dependence on medication for sleep. Choice B is incorrect because exercising before bedtime can actually stimulate the body and make it harder to fall asleep. Choice C is incorrect because consuming heavy meals in the evening can lead to indigestion and discomfort, making it difficult to sleep. Choice D is incorrect because drinking hot tea or coffee just before bedtime can interfere with sleep due to the caffeine content, which is a stimulant.
Question 3 of 5
A patient arrives in the emergency department with severe chest pain. The patient reports that the pain has been occurring off and on for a week now. Which assessment finding would indicate the need for cautious use of nitrates and nitrites?
Correct Answer: A
Rationale: The correct answer is A: Blood pressure of 88/62 mm Hg. This indicates hypotension, a contraindication for nitrates that can further lower blood pressure. Nitrates dilate blood vessels, leading to decreased preload and afterload, which can worsen hypotension. Choices B, C, and D are incorrect because an elevated pulse rate, renal disease history, and past myocardial infarction do not directly contraindicate the cautious use of nitrates and nitrites.
Question 4 of 5
A patient who has recently started therapy on a statin drug asks the nurse how long it will take until he sees an effect on his serum cholesterol. Which statement would be the nurse’s best response?
Correct Answer: B
Rationale: The correct answer is B: “It takes 6 to 8 weeks to see a change in cholesterol levels.” This is because statins typically take time to reach their full effect on lowering cholesterol levels by inhibiting the enzyme involved in cholesterol production. Within 6 to 8 weeks, the patient can expect to see a significant reduction in their serum cholesterol levels. Choice A is incorrect because blood levels do not return to normal within a week of beginning statin therapy. Choice C is incorrect as it typically does not take 6 months to see a change in cholesterol levels with statins. Choice D is incorrect as significant results can be seen before a year of therapy.
Question 5 of 5
The nurse is teaching a patient with iron-deficiency anemia about foods to increase iron intake. Which food may enhance the absorption of oral iron forms?
Correct Answer: D
Rationale: The correct answer is D: Orange juice. This is because orange juice contains vitamin C, which enhances the absorption of iron. Vitamin C helps convert non-heme iron (the type found in plants) into a form that is more easily absorbed by the body. Milk (choice A) and yogurt (choice B) contain calcium and casein, which can inhibit iron absorption. Antacids (choice C) can also decrease iron absorption by altering stomach acidity. Therefore, consuming orange juice along with iron-rich foods can help improve iron absorption in patients with iron-deficiency anemia.
