Question 1 of 5
A nurse is collecting data from a client who is receiving vancomycin for a Clostridium difficile infection. Which of the following findings is the priority for the nurse to report to the provider?
Correct Answer: D
Rationale: The correct answer is D: Creatinine 3.1 mg/dL. Elevated creatinine levels indicate potential kidney damage, which is a serious concern when a client is receiving vancomycin, a nephrotoxic medication. Acute kidney injury can occur as a complication of vancomycin therapy, leading to further health issues.
Therefore, it is crucial for the nurse to report this finding promptly to the provider for immediate intervention to prevent further kidney damage.
Choice A: Two loose stools are expected in a client with a Clostridium difficile infection, and it may not be the priority concern.
Choice B: WBC count of 11,000/mm³ is slightly elevated but not a priority over potential kidney damage.
Choice C: Heart rate of 104/min may be elevated due to infection or other factors, but it is not as critical as kidney function in this scenario.
Question 2 of 5
A nurse is preparing to administer medications to a client through an enteral feeding tube. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: The correct answer is C: Flush the tube with normal saline following medication administration. Flushing the tube with normal saline after medication administration helps ensure that the medication is completely delivered into the stomach and prevents any residual medication from clogging the tube. This action also helps prevent any potential drug interactions or reactions that may occur if different medications are inadvertently mixed in the tube. Additionally, flushing the tube with normal saline helps maintain the patency of the tube and reduces the risk of infections.
Other choices are incorrect because:
A: Pinching the tube while connecting the syringe can lead to blockage and prevent proper medication administration.
B: Elevating the head of the client's bed to 10° is a good practice for preventing aspiration during feeding, but it is not directly related to administering medications through an enteral tube.
D: Combining crushed medications in a single syringe can lead to drug interactions or inconsistent dosing.
Question 3 of 5
A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the dosage, first, convert the child's weight to kg: 44 lb / 2.2 = 20 kg. Next, calculate the total daily dose: 6 mg/kg/day * 20 kg = 120 mg/day. Since the dose is to be divided into three equal doses, each dose would be 120 mg / 3 = 40 mg. Since gentamicin is available as 40 mg/mL, the nurse should administer 1 mL for each dose (40 mg / 40 mg/mL = 1 mL).
Therefore, the correct answer is A: 1 mL.
Choices B-G are incorrect as they do not align with the calculated dose based on the child's weight and the available concentration of the medication.
Question 4 of 5
A nurse is preparing to administer amikacin 5 mg/kg IM to a client who weighs 110 lb. Available is amikacin injection 250 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if applicable. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the dose of amikacin for a client weighing 110 lb, convert the weight to kg by dividing by 2.2: 110 lb / 2.2 = 50 kg. Next, multiply the weight by the prescribed dose of 5 mg/kg: 50 kg x 5 mg/kg = 250 mg. Since the amikacin injection is 250 mg/mL, the nurse should administer 1 mL (250 mg ÷ 250 mg/mL = 1 mL).
Therefore, choice A (1 mL) is the correct answer.
Choices B-G are incorrect as they do not align with the accurate calculation based on the client's weight and the medication concentration.
Question 5 of 5
A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the dosage per dose, first convert the child's weight from pounds to kilograms: 66 lb ÷ 2.2 = 30 kg.
Then, multiply the weight by the prescribed dosage: 30 kg × 0.24 mg/kg/week = 7.2 mg/week. Since the total weekly dosage is divided into 6 daily doses, divide 7.2 mg by 6 to get the per-dose amount: 7.2 mg ÷ 6 = 1.2 mg.
Therefore, the nurse should administer 1.2 mg per dose.
Choice A (1.2 mg) is correct because it reflects this calculation. The other choices are incorrect as they do not accurately represent the calculated dosage based on the child's weight and the prescribed dosage regimen.
