Cardiovascular Pharmacology Drug Class Questions
Question 1 of 5
Anjalee Cohen’s research (as discussed by Paul Cohen) on methamphetamine use in Thailand shows that while methamphetamine used to be regarded as a performance-enhancing drug used by workers (a ‘drug of diligence’), it has recently come to be portrayed as:
Correct Answer: D
Rationale: The correct answer is D because Anjalee Cohen's research highlights the shift in perception of methamphetamine from being a 'drug of diligence' to one that causes users to become crazed and violent. This shift is supported by evidence showing the negative effects of methamphetamine on behavior, leading to erratic and violent tendencies. Choice A is incorrect as it does not align with the research findings discussed. Choice B is incorrect as it does not reflect the current portrayal of methamphetamine in Thailand as discussed in the research. Choice C is incorrect as sexual risk-taking is not the primary focus of the research findings.
Question 2 of 5
The physician tells the nurse, 'The medication I’m prescribing for the client enhances the GABA system.' Evaluation will be facilitated if the nurse correctly interprets this statement to mean the medication is expected to:
Correct Answer: B
Rationale: The correct answer is B: Decrease anxiety. GABA is an inhibitory neurotransmitter that helps regulate anxiety and stress. Enhancing the GABA system means increasing its activity, which would result in a calming effect, reducing anxiety. A: Increasing alertness is unlikely because GABA is associated with relaxation, not alertness. C: GABA's role is not primarily in reducing hallucinations. D: While GABA may indirectly influence mood, its primary role is in anxiety regulation.
Question 3 of 5
Before a patient receives triptans for the treatment of migraines, the nurse will assess for the presence of which condition, which is a contraindication if present?
Correct Answer: D
Rationale: The correct answer is D: Cardiovascular disease. Triptans can cause vasoconstriction, potentially worsening cardiovascular conditions. Assessing for cardiovascular disease is crucial to prevent adverse effects. A: Hypotension is not a contraindication for triptans. B: Renal disease does not directly interact with triptans. C: Liver damage is not a direct contraindication for triptans.
Question 4 of 5
The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?
Correct Answer: D
Rationale: Step 1: Digoxin interacts with high-fiber foods like bran muffins, decreasing its absorption. Step 2: Bran muffins can reduce the effectiveness of digoxin, leading to subtherapeutic levels. Step 3: Avoiding bran muffins can help maintain optimal digoxin levels for therapeutic effect. Summary: A - Leafy greens are okay; B - Dairy products don't interact significantly; C - Grapefruit juice can interact with certain medications, but not digoxin.
Question 5 of 5
A patient in the neurologic intensive care unit is being treated for cerebral edema. Which class of diuretic is used to reduce intracranial pressure?
Correct Answer: B
Rationale: The correct answer is B: Osmotic diuretics. Osmotic diuretics, like mannitol, are commonly used in the neurologic ICU to reduce intracranial pressure by drawing water out of the brain tissue and into the bloodstream, thus decreasing cerebral edema. Loop diuretics (A) are more commonly used for conditions like heart failure and kidney disease, not specifically for cerebral edema. Thiazide diuretics (C) are primarily used for conditions like hypertension and edema related to heart failure, not for reducing intracranial pressure. Vasodilators (D) work by dilating blood vessels and are not typically used as the first-line treatment for cerebral edema.
