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
CSF analysis and MRI are crucial in diagnosing multiple sclerosis (MS). CSF may show elevated levels of oligoclonal bands, indicative of immune system activity in the central nervous system. MRI can detect lesions or plaques in the brain and spinal cord, which are characteristic of MS.
Choice B rationale
Serum albumin and CT scan are not standard diagnostic tools for MS. Serum albumin is more relevant to liver function and nutritional status, while CT scans are less sensitive than MRIs in detecting MS lesions.
Choice C rationale
CSF proteins and angiography are not standard tests for diagnosing MS. While CSF protein levels might be altered in MS, angiography is used to visualize blood vessels and is not relevant to MS diagnosis.
Choice D rationale
Serum anti-acetylcholine antibodies and x-rays are not used to diagnose MS. Anti-acetylcholine antibodies are related to myasthenia gravis, and x-rays are not useful for visualizing MS lesions.
Correct Answer is D
Explanation
Choice A rationale
Coagulation studies assess the blood's ability to clot and are not directly related to the monitoring of phenytoin therapy. These tests are more relevant for patients with bleeding disorders or those on anticoagulant therapy.
Choice B rationale
Serum electrolytes, including levels of sodium, potassium, and calcium, are important for overall health but are not specifically indicative of phenytoin levels. Phenytoin may affect calcium metabolism, but it is not the primary focus for routine monitoring.
Choice C rationale
Renal function tests are crucial for assessing kidney function but do not directly monitor phenytoin therapy. Phenytoin is primarily metabolized in the liver, making liver function tests more relevant.
Choice D rationale
Blood glucose levels should be monitored in patients taking phenytoin as the drug can cause alterations in blood glucose levels. Both hypoglycemia and hyperglycemia have been reported, so it is important to check glucose levels to ensure they remain within a normal range.
