Common Cardiovascular Drugs Questions
Question 1 of 5
A nurse explains to a patient with a mental health disorder that which part of the brain is responsible for fine motor coordination?
Correct Answer: C
Rationale: The correct answer is C: Cerebellum. The cerebellum is responsible for fine motor coordination as it coordinates muscle movements, balance, and posture. It receives input from sensory systems and integrates this information to regulate motor movements accurately. The medulla (A) controls vital functions like breathing and heart rate. The thalamus (B) acts as a relay station for sensory information. The temporal lobe (D) is mainly involved in auditory processing and memory. Therefore, the cerebellum is the most appropriate choice for fine motor coordination due to its specific functions in motor control.
Question 2 of 5
The nurse is conducting a smoking-cessation program. Which statement regarding drugs used in cigarette-smoking–cessation programs is true?
Correct Answer: A
Rationale: The correct answer is A because rapid chewing of nicotine gum releases an immediate dose of nicotine, providing quick relief during cravings. This immediate effect helps manage withdrawal symptoms effectively. Option B is incorrect as transdermal patches provide a steady release of nicotine over time, not quick relief. Option C is incorrect; compliance is similar for both gum and patches. Option D is incorrect as the nicotine gum can be used up to 20-30 times per day, not just six.
Question 3 of 5
A patient is receiving thrombolytic therapy, and the nurse monitors the patient for adverse effects. What is the most common undesirable effect of thrombolytic therapy?
Correct Answer: D
Rationale: The correct answer is D: Internal and superficial bleeding. Thrombolytic therapy works by breaking down blood clots, which can lead to bleeding as a side effect. This occurs because the medication can also affect the body's ability to form clots at the site of injury. Internal and superficial bleeding are the most common and serious adverse effects of thrombolytic therapy. Dysrhythmias (choice A) are not typically associated with thrombolytic therapy. Nausea and vomiting (choice B) are common side effects of many medications, but not specifically thrombolytic therapy. Anaphylactic reactions (choice C) are rare but serious allergic reactions and are not the most common undesirable effect of thrombolytic therapy.
Question 4 of 5
The nurse is monitoring drug levels for a patient who is receiving theophylline. The most recent theophylline level was 13 mcg/mL, and the nurse evaluates this level to be
Correct Answer: B
Rationale: The correct answer is B: at a therapeutic level. The therapeutic range for theophylline is typically 10-20 mcg/mL. A level of 13 mcg/mL falls within this range, indicating the drug is at an appropriate concentration to provide therapeutic effects without causing toxicity. Choices A, C, and D are incorrect because they do not align with the established therapeutic range for theophylline. A level below the therapeutic range (Choice A) would indicate subtherapeutic effects, whereas a level above the therapeutic range (Choice C) would suggest potential for toxicity. A level at a toxic level (Choice D) would indicate a concentration that is harmful to the patient.
Question 5 of 5
The term “biotransformation” includes the following:
Correct Answer: D
Rationale: The correct answer is D because biotransformation refers to the process of physicochemical and biochemical alteration of a drug in the body. This process involves converting a drug into metabolites that are more easily excreted. Choice A is incorrect as it describes accumulation in fat tissue, not transformation. Choice B is incorrect as it refers to binding with plasma proteins, not transformation. Choice C is incorrect as it mentions accumulation in a tissue, not transformation. Thus, only choice D accurately defines biotransformation.
