A client who had knee replacement surgery receives a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL prefilled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.).
The Correct Answer is ["0.6"]
Step 1: The medication is prescribed as 30 mg every 12 hours, which means it is given twice a day. So, the total daily dosage in mg is 30 mg × 2 = 60 mg.
Step 2: The medication is available in 30 mg per 0.3 mL. So, to find out how many mL correspond to 60 mg, we set up a proportion: (30 mg / 0.3 mL) = (60 mg / x mL). Solving for x gives x = (0.3 mL / 30 mg) × 60 mg = 0.6 mL.
Therefore, the practical nurse should administer 0.6 mL of the medication each day.

Correct Answer is D
Explanation
The correct answer is D. Electrolytes.
Choice A rationale: The white blood cell count (WBC) is typically reviewed for signs of infection or inflammation, but it is not directly related to numbness and tingling.
Choice B rationale: Hematocrit levels assess the proportion of red blood cells in the blood, which are not commonly associated with numbness and tingling.
Choice C rationale: Albumin and protein levels are important for nutritional status and overall health but are not directly associated with numbness and tingling.
Choice D rationale: Electrolytes are crucial for nerve function and muscle contractions. Abnormal levels of electrolytes (such as calcium, potassium, or sodium) can lead to symptoms like numbness and tingling in the extremities.
Correct Answer is B
Explanation
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
