Question 1 of 5
A nurse is planning to administer a prefilled syringe of enoxaparin to a client. Which of the following actions should the nurse take?
Correct Answer: C
Rationale:
Correct
Answer: C - Administer the medication into the anterolateral or posterolateral abdominal area.
Rationale:
1. Enoxaparin is a low molecular weight heparin that is typically administered subcutaneously.
2. The anterolateral and posterolateral abdominal areas are recommended sites for subcutaneous injections due to the presence of a thick layer of adipose tissue and minimal risk of hitting blood vessels or nerves.
3. These areas have a larger surface area, which allows for better absorption and reduces the risk of tissue damage.
4. By selecting these specific areas, the nurse ensures proper administration and absorption of the medication.
Summary:
A: Massaging the injection site can cause bruising or tissue damage and is not recommended after administering enoxaparin.
B: Holding the skin taut is not necessary and may cause discomfort to the client during injection.
D: Expelling air bubbles is important to prevent air embolism but is not specific to the administration
Question 2 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: C
Rationale: The correct answer is C: Calcium. Levothyroxine absorption can be affected by calcium supplements, so the client should wait at least 4 hours after taking levothyroxine before taking calcium. Calcium can bind to levothyroxine in the gastrointestinal tract, reducing its absorption and effectiveness. Ginkgo biloba (
Choice
A), Zinc (
Choice
B), and Vitamin C (
Choice
D) do not interact significantly with levothyroxine absorption, so there is no need to wait before taking them.
Question 3 of 5
A nurse is preparing to administer heparin subcutaneously to a client. Which of the following actions should the nurse plan to take to minimize bleeding following the injection?
Correct Answer: D
Rationale:
Correct
Answer: D. Grasp skin between thumb and forefinger throughout the injection.
Rationale: By grasping the skin between thumb and forefinger throughout the injection, the nurse ensures proper technique to create a taut surface for the needle insertion. This helps to minimize bleeding post-injection by reducing the risk of hitting a blood vessel.
Summary of Incorrect
Choices:
A: Aspirating the syringe prior to injecting heparin is not necessary for subcutaneous injections and may increase the risk of tissue trauma.
B: The Z-track method is used for intramuscular injections, not subcutaneous injections like heparin.
C: Massaging the site post-injection can increase the risk of bleeding by dispersing the medication.
Question 4 of 5
A nurse is mixing NPH insulin and regular insulin prior to administration. Which of the following actions should the nurse take first?
Correct Answer: C
Rationale: The correct answer is C: Inject air into the vial with NPH insulin in it. This should be done first to prevent contamination between the two insulins. Drawing up the NPH insulin dose should follow to avoid mixing errors. Injecting air into the regular insulin vial (choice
A) or drawing up the regular insulin dose (choice
D) before the NPH insulin can lead to incorrect dosing and potential errors in insulin administration. It is crucial to follow the correct sequence to ensure accurate mixing and administration of the insulins.
Question 5 of 5
A nurse is providing teaching to a client who has a prescription for total parenteral nutrition (TPN). Which of the following information should the nurse include in the teaching?
Correct Answer: D
Rationale: The correct answer is D: You will receive TPN through a central vein. This is correct because TPN is a form of nutrition that is delivered directly into the bloodstream through a central vein, typically the subclavian vein. This method allows for the nutrients to be quickly absorbed and utilized by the body.
Explanation of why the other choices are incorrect:
A: You require TPN because your glucose is too high - This is incorrect as TPN is not typically used to address high glucose levels.
B: You will receive TPN for the next 6 months - This is incorrect because the duration of TPN therapy varies based on the individual's condition and needs.
C: You require TPN because you have a low platelet count - This is incorrect as TPN is not specifically used to address a low platelet count.
In summary, choice D is the correct answer as it pertains to the essential method of administering TPN, while the other choices are incorrect as they do
