Cardiovascular System Drugs Questions
Question 1 of 5
A patient is receiving gabapentin (Neurontin), an anticonvulsant, but has no history of seizures. The nurse expects that the patient is receiving this drug for which condition?
Correct Answer: B
Rationale: Step 1: Gabapentin is commonly used to treat neuropathic pain. Step 2: Peripheral neuropathy is a type of nerve damage that causes pain. Step 3: Since the patient has no history of seizures, the most likely reason for receiving gabapentin is to manage pain associated with peripheral neuropathy. Step 4: Therefore, the correct answer is B: Pain associated with peripheral neuropathy. Summary: - Inflammation pain (Choice A) is not typically treated with gabapentin. - Depression associated with chronic pain (Choice C) may be managed with other medications. - Prevention of seizures (Choice D) is the primary indication for gabapentin in patients with a history of seizures, not in this case.
Question 2 of 5
The nurse is preparing to administer dipyridamole (Persantine). Which statement about this drug is true?
Correct Answer: D
Rationale: The correct answer is D. Dipyridamole is used in combination with warfarin to prevent postoperative thromboembolic complications. This is because dipyridamole enhances the effects of warfarin, resulting in improved prevention of blood clots. Choice A is incorrect because dipyridamole does not have antiinflammatory or antipyretic properties. Choice B is incorrect because dipyridamole does not have analgesic properties and its main effect is antithrombotic. Choice C is incorrect because dipyridamole is not specifically indicated for reducing the risk of fatal and nonfatal thrombotic stroke.
Question 3 of 5
When educating a patient recently placed on inhaled corticosteroids, the nurse will discuss which potential adverse effects?
Correct Answer: D
Rationale: The correct answer is D because inhaled corticosteroids can lead to oral candidiasis (thrush) due to local immunosuppression and dry mouth. This is because corticosteroids can disrupt the oral mucosa's normal flora and reduce salivary flow. Fatigue and depression (A), anxiety and palpitations (B), and headache and rapid heart rate (C) are not typically associated with inhaled corticosteroid use.
Question 4 of 5
A small amount of the volume of distribution is common for lipophylic substances easy penetrating through barriers and widely distributing in plasma, interstitial and cell fluids:
Correct Answer: B
Rationale: Rationale: B is correct because lipophilic substances have high affinity for fats and are able to penetrate barriers easily. However, a small volume of distribution indicates that these substances are mainly confined to the plasma and do not distribute widely into interstitial and cell fluids. Summary: A is incorrect because a small volume of distribution indicates limited distribution, not widespread distribution as stated. C is incorrect as there is a correct answer. D is incorrect as not all choices are correct, only B is accurate based on the characteristics of lipophilic substances.
Question 5 of 5
If two drugs with the same effect, taken together, produce an effect that is equal in magnitude to the sum of the effects of the drugs given individually, it is called as:
Correct Answer: C
Rationale: Rationale: 1. When two drugs with the same effect are taken together, and their effects sum up equally, it indicates an additive effect. 2. Additive effect means the combined effect is simply the sum of individual effects. 3. Antagonism is when the effect of one drug reduces or cancels out the effect of another. 4. Potentiation is when one drug enhances the effect of another, not equal sum. 5. None of the above is incorrect as the scenario described fits the definition of an additive effect.
