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 A
Explanation
Troponin I and CK-MB are cardiac enzymes that are released into the bloodstream when the heart muscle is injured or necrotic. Elevated levels of these enzymes indicate that the client has suffered a myocardial infarction (MI) or heart attack. The damaged heart tissue can impair the electrical conduction system of the heart and cause abnormal heart rhythms or dysrhythmias, which can be life-threatening. The PN should monitor the client's cardiac status closely and report any changes to the charge nurse.
The other options are not correct because:
B. The client is not at risk for pulmonary embolism, which is a blockage of a pulmonary artery by a blood clot or other material. Pulmonary embolism does not cause elevated cardiac enzymes, but it can cause chest pain, shortness of breath, and hypoxia.
C. The client is not at risk for recurrent long-term angina pain, which is chest pain caused by reduced blood flow to the heart muscle due to narrowed or blocked coronary arteries. Angina pain does not cause elevated cardiac enzymes, but it can be a warning sign of an impending MI.
D. The lab results do not indicate risk factors for transient ischemic attack (TIA), which is a temporary interruption of blood flow to a part of the brain due to a clot or plaque. TIA does not cause elevated cardiac enzymes, but it can cause neurological symptoms such as weakness, numbness, or speech difficulties.
Correct Answer is A
Explanation
The correct answer is choicea. Teach the client to use a straw when taking the medication to reduce further tooth staining.
Choice A rationale:
Using a straw when taking liquid iron preparations helps minimize contact with the teeth, thereby reducing the risk of staining.
Choice B rationale:
While tooth discoloration can indicate that the iron is being absorbed, it is not a desired effect and should be managed to prevent cosmetic concerns.
Choice C rationale:
Assessing for mouth or gum pain and difficulty swallowing is important but not directly related to the issue of tooth staining.
Choice D rationale:
Advising the client to withhold doses without consulting a healthcare provider could lead to non-compliance and inadequate treatment of iron deficiency.
