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
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 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.
Correct Answer is D
Explanation
A. Reinforce the importance of daily weights. While reinforcing the importance of daily weights is crucial for managing heart failure, it does not address the immediate concern of the patient's weight gain and edema. The nurse needs to take a more direct action to manage the patient's current condition.
B. Call the health care provider for further instructions. Calling the health care provider is a reasonable step, but it may delay immediate intervention that the nurse can perform. Ensuring the patient is taking their prescribed diuretic can provide more immediate relief from fluid retention.
C. Document the findings and continue with the visit. Documenting the findings is necessary for accurate medical records, but it does not address the urgent need to manage the patient's symptoms. Immediate action is required to prevent further complications.
D. Ensure the client has been taking their prescribed diuretic. Ensuring the patient has been taking their prescribed diuretic is the most appropriate immediate action. Diuretics help reduce fluid buildup, which can alleviate the weight gain and edema, providing quick relief and preventing further complications.
