     Exercise:

     1、A nurse is caring for a child who sustained a head injury after falling from a tree. On assessment of the child, the nurse notes the presence of a watery discharge from the child's nose. The nurse shouldimmediately test the discharge for the presence of which substance?

     1.Protein

     2.Glucose

     3.Neutrophils

     4.White blood cells

     Correct Answer:2

     After a head injury, bleeding from the nose or ears necessitates further evaluation. A watery discharge from the nose (rhinorrhea) that tests positive for glucose is likely to be cerebrospinal fluid (CSF) leaking from a skull fracture. On noting watery discharge from the child's nose, the nurse should test the drainage for glucose using reagent strips such as Dextrostix. If the results are positive, the nurse will contact the health care provider. The items in options 1, 3, and 4 are not normally found in CSF.

     2、Zidovudine (Retrovir) has been prescribed for a client who asks the nurse about the action of the medication. The nurse responds that this medication performs which function?

     1.Increases neutrophils

     2.Kills bacteria and fungi

     3. Promotes the function of natural killer cells

     4. Slows the replication of human immunodeficiency virus (HIV)

     Correct Answer:4

     Zidovudine is a nucleoside reverse transcriptase inhibitor that is used in combination with other antiretroviral agents to treat HIV infection. It interferes with viral RNA-dependent DNA polymerase, an enzyme necessary for viral HIV replication. It slows HIV replication, reducing the progression of HIV infection. Zidovudine does not increase neutrophils, kill bacteria and fungi, or promote the function of natural killer cells.

     3、A nurse is assessing the status of a client with diabetes mellitus. The nurse interprets that the client is exhibiting adequate diabetic control if the serum level of glycosylated hemoglobin A1c is less than what percentage?

     1.7%

     2.9%

     3.10%

     4.15%

     Correct Answer:1

     An acceptable measure of diabetic control is indicated by a serum level of glycosylated hemoglobin A1c of 7.5% or less. Specific values may vary slightly, depending on the laboratory and the procedure. Options 2, 3, and 4 are inaccurate.
