Question 1 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Correct Answer: B
Rationale: The correct answer is B: Calcium. Levothyroxine should be taken on an empty stomach to ensure proper absorption. Calcium can interfere with levothyroxine absorption, so it is recommended to wait at least 4 hours between taking them. Ginkgo biloba, Vitamin C, and Zinc do not interfere significantly with levothyroxine absorption. Taking them at the same time as levothyroxine should not cause any issues.
Question 2 of 5
A nurse is preparing to administer total parenteral nutrition to a client. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: The correct answer is C: Keep the solution refrigerated until 1 hr before infusion. This is important to prevent bacterial growth and maintain the integrity of the TPN solution. Keeping it refrigerated helps to preserve the nutrients and prevent contamination.
A: Obtaining the client's weight three times a week is not directly related to administering TPN.
B: Checking the client's WBC count daily is not necessary for administering TPN.
D: Changing the solution every 36 hours is not the standard practice for TPN administration.
In summary, choice C is correct because it ensures the safety and efficacy of the TPN solution, while the other choices are not directly relevant to the administration process.
Question 3 of 5
A nurse is preparing to administer a medication to a client. Using the rights of medication administration. Which of the following actions should the nurse take to ensure the right medication is administered to the client?
Correct Answer: C

By using two identifiers (such as name and date of birth), the nurse verifies the client's identity accurately. This step helps prevent medication errors and ensures patient safety.
Option A is not as effective as it does not directly verify the client's identity. Option B involves verifying the written order but does not confirm the client's identity. Option D is after administration and does not prevent errors.
Question 4 of 5
A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Inject air into the vial to withdraw the short-acting insulin. The rationale is to prevent the formation of a vacuum in the vial when withdrawing the insulin. By injecting air, it equalizes the pressure inside the vial, making it easier to withdraw the desired amount of insulin accurately. This step ensures that the correct dosage is obtained and minimizes the risk of contamination or air bubbles in the syringe.
Choices B, C, and D are incorrect:
B: Administer the insulin within 20 min of preparing it - This is not a necessary step for mixing short-acting insulin with NPH insulin; it is more important to ensure accurate dosage.
C: Ensure the NPH insulin is drawn into the syringe first - This is incorrect as the order of drawing the insulins does not affect their mixing or effectiveness.
D: Use two separate syringes to mix the insulin - This is unnecessary and increases the risk of errors in dosage measurement
Question 5 of 5
A nurse is reviewing the list of current medications for a client who has a new prescription for nitroglycerin. The nurse should identify that which of the following client medications is contraindicated for use with nitroglycerin?
Correct Answer: A
Rationale: The correct answer is A: Sildenafil. Nitroglycerin and sildenafil both cause vasodilation, leading to a severe drop in blood pressure when taken together, which can result in a life-threatening condition called hypotension. Gemfibrozil, lansoprazole, and diazepam do not have significant interactions with nitroglycerin and are safe to use together. It is important to avoid combining medications that have similar effects on the body to prevent adverse reactions.
