Chapter 25 Cardiovascular Drugs Quizlet Questions
Question 1 of 5
A patient with a history of depression reports not feeling well rested in recent weeks. Before making the assumption that the complaint is related to depression, a nurse should investigate whether the patient has had any recent changes in:
Correct Answer: A
Rationale: The correct answer is A: work schedule that affect the hours of sleep. This is because changes in work schedule can directly impact the amount and quality of sleep a person gets, leading to feelings of not being well-rested. Investigating this factor is important before assuming the complaint is solely related to depression. Choice B: vacations taken within the same time zone, is incorrect as vacations within the same time zone should not significantly affect sleep patterns unless there are other factors involved. Choice C: fluid intake with reduced overall intake of water, is incorrect because while hydration is important for overall health, it is less likely to be the primary cause of not feeling well-rested. Choice D: food intake with decreased intake of heavy foods before bedtime, is incorrect as while diet can impact sleep quality, it is less likely to be the primary cause of feeling not well-rested in this case.
Question 2 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 3 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 4 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.
Question 5 of 5
Pharmacodynamics involves the following?
Correct Answer: B
Rationale: Pharmacodynamics refers to how drugs interact with the body to produce their effects, including both desired and undesired effects. Choice B is correct as it specifically mentions information about unwanted effects, which is a key aspect of pharmacodynamics. Choices A, C, and D are incorrect as they do not directly relate to the effects of drugs on the body. Choice A focuses on drug absorption mechanisms, Choice C refers to biological barriers not directly related to drug effects, and Choice D pertains to drug excretion rather than drug action within the body. Therefore, choice B is the most relevant to pharmacodynamics.
