Before administering an antibiotic that can cause nephrotoxicity, which laboratory value is most important for the practical nurse (PN) to review?
White blood cell count (WBC).
Serum creatinine.
Hemoglobin and Hematocrit.
Serum calcium
The Correct Answer is B
The correct answer is choice B, Serum creatinine. Choice A rationale:
The white blood cell count (WBC) is an important parameter for assessing the body's immune response to infections. While it can provide valuable information about the presence of an infection, it is not directly related to nephrotoxicity. Therefore, it is not the most important laboratory value to review before administering an antibiotic that can cause nephrotoxicity.
Choice B rationale:
Serum creatinine is a crucial laboratory value to assess kidney function. It is a waste product that is filtered by the kidneys, and its level in the blood is a reliable indicator of kidney function. If the serum creatinine level is elevated, it suggests impaired kidney function, which can be a warning sign of nephrotoxicity. Reviewing the serum creatinine level before administering nephrotoxic antibiotics is essential to ensure that the client's kidneys are functioning adequately and to avoid potential harm.
Choice C rationale:
Hemoglobin and hematocrit are indicators of the client's red blood cell count and blood's oxygen-carrying capacity. While these values can provide information about the client's overall health status, they are not directly related to nephrotoxicity. Therefore, they are not the most important laboratory values to review in this particular scenario.
Choice D rationale:
Serum calcium levels are essential for assessing bone health, nerve function, and muscle contractions. However, they are not directly related to nephrotoxicity, and reviewing serum calcium levels alone would not provide sufficient information about kidney function. Hence, it is not the most critical value to review before administering nephrotoxic antibiotics

Correct Answer is C
Explanation
The correct answer is Choice C. Soft blanket.
Choice A rationale:
A heating pad should not be applied to the client's legs with a mottled appearance. A mottled appearance indicates poor circulation, and applying heat could potentially worsen the situation by dilating blood vessels and further reducing blood flow to the extremities.
Choice B rationale:
The body lotion is not appropriate in this situation. While it may help moisturize the skin, it will not address the underlying circulation issues causing the mottled appearance. Moreover, applying lotions to areas with compromised circulation can be harmful.
Choice C rationale:
The correct choice. A soft blanket can be applied to the client's legs with a mottled appearance to provide warmth and comfort. It is essential to keep the client comfortable during palliative care, and a soft blanket can help maintain a suitable temperature without causing harm.
Choice D rationale:
Moist clothes are not indicated in this situation. They may potentially worsen the mottled appearance by adding moisture to the skin, and it won't address the circulation issues causing the discoloration.
Correct Answer is B
Explanation
The correct answer is **b. Oral feeding of a two-year-old child after application of a hip spica cast.**
Choice A rationale:
Participation in staff rounds to record notes regarding client goals is not an appropriate task to delegate to a UAP. This task requires clinical assessment, judgment, and documentation skills that are within the scope of practice of a licensed practical nurse (PN), but not a UAP.
Choice B rationale:
Oral feeding of a two-year-old child after application of a hip spica cast is an appropriate task that the PN can delegate to a UAP. Feeding a stable patient is a routine task that does not require advanced nursing skills or clinical judgment. As long as the child is not at high risk for complications, this task can be safely delegated to a UAP with proper training and supervision.
Choice C rationale:
Evaluation of a client's incisional pain following narcotic administration is not an appropriate task to delegate to a UAP. This task requires clinical assessment, evaluation of medication effects, and critical thinking skills that are within the scope of practice of a PN, but not a UAP.
Choice D rationale:
Assessment of the placement and patency of a nasogastric feeding tube is not an appropriate task to delegate to a UAP. This task requires specialized nursing skills and clinical judgment to ensure the safety and effectiveness of the feeding tube. It is within the scope of practice of a PN, but not a UAP.
