A nurse is caring for a client who has cancer and is receiving total parenteral nutrition (TPN). Which of the following lab values indicates the treatment is effective?

Albumin 4.2 g/dL

Calcium 9.4 mg/dL

Hct 43%

WBC 8,000/uL

Answer and Explanation

The Correct Answer is A

A.   Albumin is a protein that is produced by the liver and is a good indicator of nutritional status. TPN is intended to provide adequate nutrition to the patient, so an increase in albumin levels would indicate that the treatment is effective.
B.   Calcium levels are not directly related to the effectiveness of TPN. Calcium levels can be affected by a variety of factors and are not a specific marker for the effectiveness of TPN.
C.   Hematocrit (Hct) measures the percentage of red blood cells in the blood. It is not directly related to the effectiveness of TPN.
D.   White blood cell count (WBC) is a marker of immune function and is not directly related to the effectiveness of TPN.

Correct Answer is C

Explanation

A. A WBC count of 5,000/mm3 is within the normal range (4,000-11,000/mm3) and is not a priority value to monitor in a client with HIV.
B. A platelet count of 150,000/mm3 is within the normal range (150,000-400,000/mm3) and is not a priority value to monitor in a client with HIV.
C. The CD4-T-cell count is a key indicator of the immune system's function in clients with HIV. A CD4-T-cell count of 180 cells/mm3 is significantly below the normal range (500-1,500 cells/mm3) and indicates a weakened immune system, which is a priority concern in clients with HIV.
D. A positive Western blot test confirms the diagnosis of HIV, but it does not provide information about the severity of the client's condition or their immune system function.

A. Use a dosimeter to measure the level of radiation in the area before intervening. B. Choose the highest level of protection equipment available. C. Wait until the type of equipment needed is known. D. Decontaminate victims before intervening.

Correct Answer is B

Explanation

A. Using a dosimeter to measure radiation levels may be necessary in certain situations, but it is not the first step in determining what type of PPE to use.
B. Choosing the highest level of protection equipment available is important in minimizing the chances of the provider contacting the disease.
C. Waiting before delivering care might lead to loss of valuable time.
D. Decontaminating victims before intervening is not the nurse's responsibility. The focus should be on protecting oneself and providing care to those who need it.
