Correct Answer is A
Explanation
Choice A rationale
Naloxone is an opioid antagonist that rapidly reverses the effects of opioid overdose, including respiratory depression. It binds to opioid receptors and displaces the opioid molecules, reversing their effects.
Choice B rationale
Bisacodyl is a stimulant laxative used to treat constipation. It does not have any effect on opioid-induced respiratory depression.
Choice C rationale
Flumazenil is a benzodiazepine antagonist used to reverse the effects of benzodiazepines, not opioids. It is not effective in treating opioid-induced respiratory depression.
Choice D rationale
Pentazocine is an opioid agonist-antagonist used for pain relief. It does not reverse opioid-induced respiratory depression and can potentially worsen the condition.
Correct Answer is B
Explanation
Choice A rationale
Crushing tadalafil is not recommended as it can alter the medication’s effectiveness and absorption. Tadalafil should be taken whole to ensure proper dosage and efficacy.
Choice B rationale
Tadalafil can decrease blood pressure by relaxing blood vessels, which allows for increased blood flow. This is a known effect of phosphodiesterase type 5 (PDE5) inhibitors like tadalafil.
Choice C rationale
Tadalafil should not be taken more than once a day. Taking it twice a day can increase the risk of side effects and is not recommended.
Choice D rationale
The effects of tadalafil can last up to 36 hours, not just 4 hours. This prolonged duration is one of the reasons it is preferred by some patients.
