Nursing Elites

1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

• A. 400 mg
• B. 200 mg
• C. 1600 mg
• D. 100 mg

Correct answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

2. The nurse is preparing to administer a blood transfusion to a client. Which action should the LPN/LVN take to ensure the client's safety?

• A. Check the client's identification and blood type.
• B. Monitor the client's vital signs every hour during the transfusion.
• C. Administer the blood through a peripheral IV line.
• D. Verify the blood product with another nurse before administration.

Correct answer: D

Rationale: To ensure the client's safety during a blood transfusion, it is crucial to verify the blood product with another nurse before administration. This step helps confirm the correct blood type and prevents transfusion reactions. While checking the client's identification and blood type (Choice A) is important, the ultimate responsibility lies with confirming the blood product before administration. Monitoring vital signs (Choice B) is necessary during a transfusion but does not directly address verifying the blood product. Administering blood through a peripheral IV line (Choice C) is a common practice but does not specifically ensure that the correct blood product is being administered, which is essential for the client's safety.

3. The provider orders Lanoxin (digoxin) 0.125 mg PO and furosemide 40 mg every day. Which of these foods would the nurse reinforce for the client to eat at least daily?

• A. Spaghetti
• B. Watermelon
• C. Chicken
• D. Tomatoes

Correct answer: B

Rationale: The correct answer is 'Watermelon.' Watermelon is high in potassium, which is important to counteract the potassium loss caused by furosemide. Furosemide is a loop diuretic that can lead to potassium depletion, so consuming potassium-rich foods like watermelon can help maintain electrolyte balance. Choices A, C, and D do not specifically address the need for potassium in this scenario and are not as beneficial for addressing the potential electrolyte imbalance caused by furosemide.

4. The nurse is preparing to administer a subcutaneous injection of enoxaparin (Lovenox). Which site is most appropriate for the LPN/LVN to use?

• A. Deltoid muscle
• B. Ventrogluteal site
• C. Abdomen
• D. Dorsogluteal site

Correct answer: C

Rationale: The abdomen is the most appropriate site for administering subcutaneous injections of enoxaparin (Lovenox). Enoxaparin is typically administered in the abdomen due to better absorption and reduced risk of injury to underlying structures. The deltoid muscle is not recommended for subcutaneous injections of enoxaparin due to the potential risk of injury to underlying structures. The ventrogluteal and dorsogluteal sites are more appropriate for intramuscular injections rather than subcutaneous injections.

5. During a follow-up visit, a home health nurse notices that a client with a gastrostomy tube, who receives intermittent feedings and medications, has developed diarrhea. Which of the following findings should the nurse identify as a possible cause of the diarrhea?

• A. The client’s caregiver washes out the feeding bag once every 24 hours with warm water.
• B. The client’s caregiver washes out the feeding bag with hot water every 24 hours.
• C. The client’s caregiver changes the feeding bag every 48 hours.
• D. The client’s caregiver adds water to the formula before administration.

Correct answer: A

Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.
