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 D
Explanation
A high blood urea nitrogen (BUN) level indicates impaired renal function, which can be caused by dehydration, infection, or nephrotoxic drugs. Chemotherapy can damage the kidneys and increase the risk of renal failure. The PN should report this finding to the charge nurse, as it may require fluid replacement, dose adjustment, or discontinuation of the chemotherapy.
The other options are not correct because:
A. Periodic nausea and vomiting are common side effects of chemotherapy that can be managed with antiemetics, hydration, and dietary modifications. They are not as urgent as a high BUN level.
B. Decreased deep tendon reflexes may indicate hypocalcemia, hypomagnesemia, or peripheral neuropathy, which can be caused by chemotherapy or other factors. They are not as urgent as a high BUN level.
C. A platelet count of 135,000/mm3 or 135 x 10^9/L is slightly below the normal range, but not significantly low. Chemotherapy can cause thrombocytopenia, which increases the risk of bleeding. The PN should monitor the client for signs of bleeding, but this finding is not as urgent as a high BUN level.
Correct Answer is A
Explanation
The injury description by the mother varies from the child's version.
Choice A rationale:
The practical nurse (PN) should note the significant indicator of possible child abuse, which is the discrepancy between the mother's description of the injury and the child's version. In cases of child abuse, perpetrators often provide inconsistent or conflicting explanations about how the injuries occurred, raising suspicion of maltreatment. This inconsistency can be a red flag for the PN to further assess the situation and, if necessary, report concerns to the appropriate authorities.
Choice B rationale:
While the child looking at the floor when answering questions might be a behavior worth noting, it alone is not a definitive indicator of child abuse. Children may exhibit various emotional responses for various reasons, and it requires further assessment to determine if there are signs of abuse.
Choice C rationale:
The healing of abrasions on the child's arms, legs, and chest does not necessarily indicate child abuse. Children are active and prone to minor injuries, which are a normal part of growing up. The PN should investigate further to determine the cause of the injuries.
Choice D rationale:
The mother describing in detail what she did for her injured child does not automatically suggest child abuse. It is essential for the PN to gather more information and conduct a comprehensive assessment before drawing any conclusions.
