3. Protein, 100 mg/dL 4. White blood cells, 3 cells/mm3


ANS: 3


Rationale: Protein (15 to 45 mg/dL) and glucose (50 to 75 mg/dL) normally are present in CSF; however, the protein level is above the expected range. The adult with normal CSF has no red blood cells in the CSF. The client may have small numbers of white blood cells (0 to 5 cells/mm3).


Test-Taking Strategy: To answer this question accurately, you must be familiar with the normal components of CSF as well as normal values of the CSF. Read each option carefully and remember that the normal protein level is between 15 and 45 mg/dL. Review the normal findings in CSF analysis if you had difficulty with this question.

22. The client with a history of seizure disorder is having a routine serum phenytoin level drawn. The nurse who receives a telephone report of the results notes that the client’s blood level of the medication is within the therapeutic range if the value reported is which of the following? 1. 6 mcg/mL 2. 15 mcg/mL 3. 28 mcg/mL 4. 35 mcg/mL


ANS: 2


Rationale: The therapeutic range for serum phenytoin (Dilantin) level is 10 to 20 mcg/mL. If the level is below the therapeutic range, the client could experience seizure activity. If the level is too high, the client is at risk for phenytoin toxicity.


Test-Taking Strategy: To answer this question accurately, you must be familiar with the therapeutic reference range for this laboratory test. Remember that the normal range is 10 to 20 mcg/mL. Review the therapeutic phenytoin level if you had difficulty with this question.
