A patient who is addicted to heroin is admitted to the hospital for treatment of an infection. The patient is prescribed methadone (Dolophine) as part of a detoxification program. What is the rationale for using methadone in this patient?
Methadone prevents withdrawal symptoms and reduces cravings for heroin.
Methadone blocks the euphoric effects of heroin and discourages its use.
Methadone stimulates opioid receptors and enhances natural pain relief.
Methadone reverses the respiratory depression caused by heroin overdose.
The Correct Answer is B
The correct answer is choice B. Methadone blocks the euphoric effects of heroin and discourages its use. Methadone is a synthetic opioid analgesic that produces a cross-tolerance to other narcotics, thereby preventing the user from feeling the high of heroin. Methadone also reduces withdrawal symptoms and cravings for heroin.
Choice A is wrong because methadone does not prevent withdrawal symptoms, but rather reduces them.
Choice C is wrong because methadone does not stimulate opioid receptors, but rather occupies them and blocks their activation by heroin.
Choice D is wrong because methadone does not reverse the respiratory depression caused by heroin overdose, but rather carries a risk of overdose itself.

Explanation
The correct answer is choice A, B, C and E.Aspirin is a medication that can prevent cardiovascular events by inhibiting platelet aggregation and reducing inflammation.
However, aspirin also has some side effects that the patient should be aware of and report to the doctor if they occur.
Choice A is correct because taking aspirin with food or milk can reduce the risk of stomach irritation and ulcers that aspirin can cause.
Choice B is correct because aspirin can increase the risk of bleeding and bruising due to its antiplatelet effect.The patient should monitor for signs of bleeding such as black, tarry stools, bloody or cloudy urine, vomiting of blood or material that looks like coffee grounds, and unusual bleeding or bruising.
Choice C is correct because taking other NSAIDs (nonsteroidal anti-inflammatory drugs) concurrently with aspirin can increase the risk of stomach ulcers and bleeding.
NSAIDs include ibuprofen, naproxen, diclofenac, and others.
Choice D is wrong because tinnitus (ringing in the ears) is a sign of aspirin toxicity and should not be ignored.The patient should stop taking aspirin and seek medical attention if they experience tinnitus, confusion, hallucinations, rapid breathing, or seizures.
Choice E is correct because enteric-coated tablets can reduce the gastric irritation caused by aspirin by delaying its release until it reaches the small intestine.However, enteric-coated tablets may not be as effective as regular tablets in preventing cardiovascular events.
