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 optimal absorption. Calcium can interfere with the absorption of levothyroxine, so it is recommended to wait at least 4 hours after taking levothyroxine before consuming calcium supplements. Ginkgo biloba, Vitamin C, and Zinc do not significantly interfere with levothyroxine absorption, so there is no need to wait specifically for them. Calcium is the correct choice because of its known interference with levothyroxine absorption.
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.
Total parenteral nutrition (TPN) solution should be kept refrigerated to maintain stability and prevent bacterial growth. It should be allowed to warm up to room temperature before administration to prevent adverse effects like hypothermia.
A: Obtaining the client's weight three times a week is important for monitoring fluid status but not directly related to administering TPN.
B: Checking the client's WBC count daily is not necessary for administering TPN unless clinically indicated for other reasons.
D: Changing the solution every 36 hours is not typically necessary; TPN solution changes are usually done every 24 hours to prevent contamination.
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
Rationale: The correct answer is C: Use two client identifiers prior to administering the medication. This is crucial to ensure that the right medication is administered to the right client. By using two identifiers, such as the client's name and date of birth, the nurse can double-check and verify the client's identity before giving the medication. This helps prevent medication errors and ensures patient safety.
Choice A is incorrect because asking another nurse to check the medication dosage is related to verifying the right dose, not the right medication.
Choice B is incorrect because verifying a written order with the medication administration record is important but does not specifically ensure the right medication is administered.
Choice D is incorrect because documenting the medication after administration does not prevent errors in medication administration.
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:
Rationale: Option A is correct because when mixing short-acting insulin with NPH insulin, air should be injected into the NPH insulin vial first to prevent creating a vacuum. This allows for easier withdrawal of the short-acting insulin. Injecting air into the short-acting insulin vial could lead to contamination of the insulin. Option B is incorrect because insulin should be administered within 5-10 minutes of mixing, not 20. Option C is incorrect since the short-acting insulin should be drawn into the syringe first to avoid contamination. Option D is incorrect as using two separate syringes is unnecessary and increases the risk of dosing errors.
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 and together can lead to severe hypotension. Sildenafil is a phosphodiesterase type 5 inhibitor used for erectile dysfunction. Gemfibrozil is a lipid-lowering agent, Lansoprazole is a proton pump inhibitor, and Diazepam is a benzodiazepine, none of which have significant interactions with nitroglycerin.
