Correct Answer: A

Rationale: Filgrastim works by stimulating the production of white blood cells. Therefore, monitoring the white blood cell (WBC) count is essential to assess the effectiveness of the treatment. Choice B, serum potassium, is not directly affected by filgrastim therapy. Choice C, hemoglobin level, is important but not the primary indicator of filgrastim's effectiveness. Choice D, serum creatinine, is unrelated to the action of filgrastim and would not reflect its effectiveness.

Correct Answer: B

Rationale: The correct action for the nurse to take when noticing a discrepancy between the client's current IV infusion and the information received during the shift report is to compare the current infusion with the prescription in the client's medication record. This step is crucial to ensure the accuracy of the prescribed treatment and to prevent any potential harm to the client. Option A is incorrect because completing an incident report should only be done after verifying the discrepancy. Option C is incorrect as contacting the charge nurse should come after confirming the details. Option D is incorrect as submitting a written warning is not appropriate without verifying the information first.

Correct Answer: B

Rationale: Limiting the intake of phosphorus-rich foods is appropriate for a client with chronic kidney disease. In individuals with chronic kidney disease, the kidneys cannot filter phosphorus effectively, leading to a buildup in the blood. This can result in bone and heart problems. Therefore, reducing phosphorus intake is crucial to prevent complications. Choices A, C, and D are incorrect. Increasing potassium intake may be harmful as potassium levels can accumulate in the blood with impaired kidney function. Encouraging protein-rich foods may not be suitable as excessive protein intake can strain the kidneys. Advising to increase fluid intake should be done cautiously as individuals with chronic kidney disease may need to restrict fluids based on their stage of the disease.

Correct Answer: B

Rationale: The correct answer is B: 'Choose lean cuts of beef.' Selecting lean cuts of beef is crucial in reducing solid fat consumption for individuals with high cholesterol levels. Lean cuts contain less saturated fat compared to fatty cuts, thus aiding in managing cholesterol levels. Option A is incorrect as oils with trans fats should be avoided since they contribute to unhealthy fats. Option C is not directly related to reducing solid fat consumption. Option D, while suggesting a leaner meat option, does not address the issue of solid fat consumption as directly as choosing lean cuts of beef.

Correct Answer: D

Rationale: The LPN should question the assignment of replacing the PCA pump cartridge and tubing as it is outside the LPN's scope of practice. LPNs are not trained to handle tasks related to PCA pumps, which involve medication administration and monitoring that are typically within the RN's responsibilities. Assisting a postop client with an incentive spirometer (Choice A), collecting a clean catch urine specimen (Choice B), and providing nasopharyngeal suctioning for a client with pneumonia (Choice C) are all tasks that fall within the LPN's scope of practice and do not require questioning by the LPN.
