Question 1 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 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 reviewing the medication administration record for a client who has cancer and is receiving morphine via a PCA pump. Which of the following prescriptions should the nurse clarify with the provider?
Correct Answer: A
Rationale: The correct answer is A: Nalbuphine. Nalbuphine is a mixed opioid agonist-antagonist and may antagonize the effects of morphine, leading to decreased pain relief. The nurse should clarify this prescription with the provider to avoid potential interference with the effectiveness of morphine.
Summary of other choices:
B: Acetaminophen - Safe to administer with morphine for pain management.
C: Ondansetron - Used for nausea and vomiting, does not directly interact with morphine.
D: Insulin glargine - Used for diabetes management, does not interact with morphine.
Question 4 of 5
A nurse is caring for a client who is experiencing severe vomiting. Which of the following medications should the nurse plan to administer?
Correct Answer: C
Rationale: The correct answer is C: Prochlorperazine. This medication is an antiemetic that helps in controlling severe vomiting. It works by blocking dopamine receptors in the brain, reducing nausea and vomiting. Propafenone (
A) is an antiarrhythmic drug, not indicated for vomiting. Simvastatin (
B) is a statin used for lowering cholesterol. Metformin (
D) is an antidiabetic medication. These choices are incorrect for treating severe vomiting as they do not have antiemetic properties.
Question 5 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: B
Rationale: The correct answer is B: Grasp skin between thumb and forefinger throughout the injection. This technique helps to create tension in the skin, making it easier for the needle to penetrate the subcutaneous tissue and reducing the risk of bleeding. Massaging the site (choice
A) can actually increase the risk of bleeding by disrupting the clotting process. The Z-track method (choice
C) is used for intramuscular injections, not subcutaneous. Aspirating the syringe (choice
D) is not necessary for subcutaneous injections as there are no large blood vessels in the subcutaneous tissue.
Therefore, grasping the skin between thumb and forefinger is the correct technique to minimize bleeding following a subcutaneous injection.
