First Aid Cardiovascular Drugs Quizlet Questions
Question 1 of 5
A client with severe depression has sleep disturbance and anorexia. The nurse’s planning will be enhanced by understanding that these symptoms may be attributed to dysfunction of the:
Correct Answer: C
Rationale: The correct answer is C: Hypothalamus. The hypothalamus plays a crucial role in regulating sleep, appetite, and other basic functions related to survival. Dysfunction in the hypothalamus can lead to sleep disturbances and anorexia, as seen in severe depression. The other choices (A, B, and D) are not directly responsible for regulating sleep and appetite, making them incorrect in this context. The cerebellum is involved in motor coordination, the basal ganglia in motor control and habit formation, and the occipital lobe in visual processing.
Question 2 of 5
When applying transdermal nitroglycerin patches, which instruction by the nurse is correct?
Correct Answer: A
Rationale: The correct answer is A: Rotate application sites with each dose. This instruction is crucial to prevent skin irritation and tolerance development. By rotating sites, the skin has time to recover, ensuring optimal absorption. Choice B is incorrect as using only the chest area can lead to skin irritation. Choice C is incorrect because the patch should not be removed when swimming as it may affect drug delivery. Choice D is incorrect as applying the patch to the same site can cause localized skin reactions and reduced effectiveness. Rotation is key for consistent drug absorption and minimizing skin irritation.
Question 3 of 5
When teaching a patient who is beginning antilipemic therapy about possible drug-food interactions, the nurse will discuss which food?
Correct Answer: B
Rationale: The correct answer is B, Grapefruit juice. Grapefruit juice can interact with antilipemic drugs by inhibiting the enzyme CYP3A4, leading to increased drug levels in the body and potential toxicity. Oatmeal (A) is a healthy food choice and does not significantly interact with antilipemic drugs. Licorice (C) can interact with medications such as corticosteroids but not specifically antilipemic drugs. Dairy products (D) can interfere with the absorption of some medications but do not have a significant interaction with antilipemic drugs.
Question 4 of 5
A woman who is planning to become pregnant should ensure that she receives adequate levels of which supplement to reduce the risk for fetal neural tube defects?
Correct Answer: D
Rationale: The correct answer is D, folic acid. Folic acid is essential for the development of the fetal neural tube, reducing the risk of defects. Adequate levels are crucial before and during pregnancy. Vitamin B12 is important for neurological function, but not specifically for neural tube development. Vitamin D is important for calcium absorption but not directly related to neural tube defects. Iron is essential for red blood cell formation but does not specifically reduce the risk of neural tube defects.
Question 5 of 5
What does “affinity” mean?
Correct Answer: B
Rationale: The correct answer is B because "affinity" refers to how tightly a drug binds to a receptor. This is crucial for the drug to exert its pharmacological effect. A: Plasma protein binding is not specifically related to affinity but affects drug distribution. C: Inhibiting potency is different from affinity, which is about binding strength. D: Bioavailability is about drug absorption, not binding to receptors. Thus, B is the most appropriate choice.
