A patient who has developed opioid tolerance will experience which effect?
Decreased constipation
Increased respiratory depression
Increased euphoria
Decreased analgesic effect
The Correct Answer is D
Choice A reason: Opioid tolerance does not reduce constipation; it may persist or worsen. Tolerance primarily reduces pain relief, so this is incorrect for the effect.
Choice B reason: Respiratory depression risk may not increase with tolerance, as sensitivity to this effect also diminishes. Analgesia is most affected, so this is incorrect.
Choice C reason: Euphoria typically decreases with tolerance, not increases, as receptor sensitivity drops. Reduced analgesia is the primary effect, so this is incorrect.
Choice D reason: Opioid tolerance leads to decreased analgesic effect, requiring higher doses for pain relief. This is the hallmark of tolerance, making it the correct choice.

Correct Answer is A
Explanation
Choice A reason: Furosemide, a loop diuretic, reduces blood volume, often lowering blood pressure. Monitoring for hypotension is critical to prevent dizziness or shock, making this the correct manifestation to observe.
Choice B reason: Decreased temperature is not a common effect of furosemide, which primarily affects fluid balance. Blood pressure changes are more relevant, so this is incorrect.
Choice C reason: Furosemide may increase heart rate due to volume loss, not decrease pulse. Hypotension is a primary concern, making this incorrect for the expected manifestation.
Choice D reason: Decreased respiratory rate is unrelated to furosemide, which may improve breathing in heart failure but not slow respiration. Blood pressure is key, so this is incorrect.
Correct Answer is ["C","E"]
Explanation
Choice A reason: Verapamil is not used for preterm labor; calcium channel blockers like nifedipine are preferred. Verapamil targets cardiovascular conditions, so this is incorrect for its therapeutic use.
Choice B reason: Verapamil is contraindicated in heart block, as it slows conduction. It is used for hypertension and dysrhythmias, not conduction blocks, so this is incorrect.
Choice C reason: Verapamil is a channel blocker used for essential hypertension, effectively reducing blood pressure by relaxing vessels. This is a standard use, making it a correct choice.
Choice D reason: Hypocalcemia is not treated with verapamil; it may worsen with calcium channel blockers. Cardiovascular indications are primary, so this is incorrect.
Choice E reason: Verapamil is used for cardiac dysrhythmias, such as supraventricular tachycardia, by slowing heart rate. This is a recognized indication, making it a correct choice.
