Answer to Question 1

A, C, E
The fat-soluble vitamins (A, D, E, and K) are stored in massive amounts in the body. Of the wa-ter-soluble vitamins, B12 can be stored; all others must be replenished with frequent ingestion.

Answer to Question 2

C
Patients taking benzodiazepines for anxiety sometimes develop paradoxical responses to the drug, which include insomnia, excitation, euphoria, heightened anxiety, and rage. A missed dose would trigger withdrawal symptoms, which would include anxiety, insomnia, sweating, tremors, and dizziness. Because this is a paradoxical reaction to the drug, a longer-acting drug would make the symptoms worse. This is not caused by overdose, which would manifest as drowsiness, lethargy, and confusion, so a drug level is not warranted.
