A nurse is caring for a client who has human immunodeficiency virus (HIV). Which of the following laboratory values would be most concerning to the nurse?

Positive Western blot test

CD4-T-cell count 505 cells/mm³ (nl. 500-1500 cells/mm³)

Platelets 115,000/mm³ (nl. 140,000-400,000/mm³)

White blood cell (WBC) count 800/mm³ (nl. 5000-10,000/mm³)

Answer and Explanation

The Correct Answer is D

A. A positive Western blot test confirms the diagnosis of HIV, but it is not concerning once the diagnosis has been established.
B. A CD4-T-cell count of 505 cells/mm³ is low but not critically low. While it does indicate immunosuppression, it is not the most concerning value presented.
C. A platelet count of 115,000/mm³ is lower than normal and may indicate a risk for bleeding, but it is not as concerning as a critically low white blood cell count.
D. A WBC count of 800/mm³ is severely low and indicates a high risk for infection, which is particularly concerning in a client with HIV, as it suggests significant immunosuppression and vulnerability to opportunistic infections.

Correct Answer is A

Explanation

A. Insulin lispro is a rapid-acting insulin that should be administered 15-30 minutes before a meal to manage blood glucose levels effectively. This timing helps to match the peak action of the insulin with the rise in blood glucose levels after eating.
B. Hypoglycemia from insulin lispro typically occurs within 1-3 hours of administration, not 4 hours later. Regular monitoring during this time frame is more appropriate.
C. An increase in appetite is not a direct result of insulin lispro administration and does not indicate insulin effectiveness or safety.
D. Insulin lispro and insulin glargine should not be mixed in the same syringe as they have different action profiles and pH levels, which can affect their efficacy.

A. WBC count in CSF B. Muscle weakness C. Altered level of consciousness D. Kernig sign result E. Body temperature at 2105

Correct Answer is {"A":{"answers":"A,B"},"B":{"answers":"A,B"},"C":{"answers":"A,B"},"D":{"answers":"A"},"E":{"answers":"A,B"}}

Explanation

A high white blood cell (WBC) count in cerebrospinal fluid (CSF) is more commonly associated with bacterial meningitis, characterized by a high neutrophil count, low glucose, and high protein levels. it is also seen in encephalitis and reflects the individual cell lines that are affected.

Muscle weakness and altered levels of consciousness can occur in both conditions but are more prominent in encephalitis, which often presents with focal neurological deficits and seizures. The

Kernig sign, a classical sign of meningitis, is a physical examination finding that indicates irritation of the meninges and supports a diagnosis of bacterial meningitis when positive.

An elevated body temperature is common in bacterial meningitis, but it is not exclusive and can be observed in encephalitis as well.
