The provider has ordered intramuscular (IM) injections of morphine, a narcotic, every 4 hours as needed for pain in a motor vehicle accident victim.
The nurse is aware this drug has a high abuse potential.
Under what category would morphine be classified?
Schedule I.
Schedule III.
Schedule IV.
Schedule II.
The Correct Answer is D
Choice A rationale
Schedule I drugs have no medical use and high abuse potential, unlike morphine.
Choice B rationale
Schedule III drugs have less abuse potential than Schedule II, making this incorrect for morphine.
Choice C rationale
Schedule IV drugs have even lower abuse potential, incorrect for morphine.
Choice D rationale
Schedule II drugs have high abuse potential with medical use, fitting morphine's classification.

Correct Answer is A
Explanation
Choice A rationale
Acetaminophen is recommended for children because it is effective for pain and fever relief with a low risk of stomach irritation and other side effects.
Choice B rationale
Ibuprofen, though effective, may cause stomach irritation and should be used with caution in children.
Choice C rationale
Aspirin is not recommended for children due to the risk of Reye’s syndrome, a rare but serious condition.
Choice D rationale

Correct Answer is B
Explanation
Choice A rationale
Thiazide diuretics do not block the sodium pump. They act primarily on the distal convoluted tubule in the kidneys.
Choice B rationale
Thiazide diuretics block the chloride pump in the distal convoluted tubule, preventing the reabsorption of sodium and chloride, leading to increased urine output and decreased blood pressure.
Choice C rationale
Thiazide diuretics do not block the carbonic anhydrase pump. This action is associated with carbonic anhydrase inhibitors.
Choice D rationale
Thiazide diuretics do not block the potassium pump. They can cause potassium loss as a side effect, but this is not their primary mechanism of action.
