Question 1 of 5
A family member asks a mental health nurse, “I am reading a lot of information about gene therapy in the news lately. Will gene therapy be able to help my spouse, who has schizophrenia?” Which response by the nurse is best?
Correct Answer: C
Rationale: The correct answer is C because gene therapy is indeed still an experimental field, especially in the context of treating mental health disorders like schizophrenia. This is due to the complex nature of mental health conditions and the need for more research to fully understand how gene therapy can effectively target and treat such disorders. Choice A is incorrect because the popularity of gene therapy for schizophrenia is not dependent on geographical location. Choice B is incorrect as the high cost is not the primary reason why gene therapy is not widely used for schizophrenia. Choice D is incorrect as it acknowledges the promise of gene therapy for schizophrenia but highlights the lack of sufficient large-scale studies, which further supports the notion that gene therapy is not yet a standard treatment for the condition.
Question 2 of 5
A 74-year-old professional golfer has chest pain that occurs toward the end of his golfing games. He says the pain usually goes away after 1 or 2 sublingual nitroglycerin tablets and rest. What type of angina is he experiencing?
Correct Answer: A
Rationale: The correct answer is A: Classic angina. This type of angina is characterized by chest pain occurring predictably with exertion and relieved by rest or nitroglycerin. In this case, the golfer experiences pain at the end of games, consistent with exertional angina. Variant angina (B) occurs at rest due to coronary artery spasm. Unstable angina (C) is characterized by chest pain at rest that is new or changing in pattern. Prinzmetal's angina (D) is also due to coronary artery spasm but typically occurs at rest and is not necessarily related to exertion.
Question 3 of 5
A patient with risk factors for coronary artery disease asks the nurse about the “good cholesterol” laboratory values. The nurse knows that “good cholesterol” refers to which lipids?
Correct Answer: D
Rationale: The correct answer is D: High-density lipoproteins (HDLs). HDLs are known as "good cholesterol" because they help remove LDL cholesterol from the arteries, reducing the risk of heart disease. High levels of HDL are associated with a lower risk of coronary artery disease. Triglycerides (A), LDLs (B), and VLDLs (C) are not considered "good cholesterol." Triglycerides are a type of fat in the blood that can increase the risk of heart disease when elevated. LDLs are often referred to as "bad cholesterol" as they can lead to plaque buildup in the arteries. VLDLs are another type of lipoprotein that carries triglycerides and can contribute to heart disease risk.
Question 4 of 5
The nurse is reviewing the medical record of a patient before giving a new order for iron sucrose (Venofer). Which statement regarding the administration of iron sucrose is correct?
Correct Answer: D
Rationale: The correct answer is D because monitoring for hypotension during iron sucrose infusion is crucial due to the risk of anaphylactic reactions. Hypotension is a common early sign of an allergic reaction. Choices A and B are incorrect as iron sucrose is typically given on an empty stomach and is safe for patients with renal disease. Choice C is incorrect as a test dose is not usually required for iron sucrose administration.
Question 5 of 5
Pharmacodynamics involves the study of following?
Correct Answer: A
Rationale: Pharmacodynamics is the study of how drugs interact with the body to produce their effects, focusing on mechanisms of drug action. This includes drug-receptor interactions, signal transduction pathways, and physiological responses. Biotransformation (choice B), distribution (choice C), and excretion (choice D) are aspects of pharmacokinetics, not pharmacodynamics. Pharmacokinetics deals with drug absorption, distribution, metabolism, and excretion in the body. Therefore, choice A is the correct answer as it directly relates to the study of pharmacodynamics.
