Question 1 of 5
A staff nurse is working with a client on the medical unit. The health care provider prescribes aspirin for the client to treat headache. The client forgets and drinks two bottles of beer, which caused GI bleeding. How should the nurse analyze this drug-drug interaction?
Correct Answer: C
Rationale: The correct answer is C: Additive reaction. Aspirin and alcohol have additive effects on the GI tract, leading to an increased risk of GI bleeding. Aspirin is known to irritate the stomach lining and increase the risk of bleeding, while alcohol can also irritate the stomach and exacerbate this effect. When combined, the effects of both substances add up, resulting in a higher likelihood of GI bleeding.
A: Antagonistic reaction - This is incorrect because an antagonistic reaction would imply that one substance lessens the effect of the other, which is not the case here.
B: Synergistic reaction - This is incorrect because a synergistic reaction would imply that the combined effect is greater than the sum of the individual effects, which is not the case here.
D: Neutral reaction - This is incorrect because a neutral reaction would imply that there is no interaction between the substances, which is not true in this scenario.
